Introduction
This Hydraulic Hose Training manual has been put together by an Australian Company based on the Gold Coast. Mobile Hose Fixers & Hydraulics has been operating for over 20 years so we know a few things about Hoses, Fittings and High Pressure Hydraulics.
You can use this course as both a guide and a reference to assist you to
carry out your work safely, efficiently and most importantly profitably.
As a Hydraulic Hose Technician, you must make a systematic
review of each situation and then select and install hoses and fittings and
other spare or replacement parts necessary to fulfil the requirements of the
application.
It is absolutely important that you observe and obey all safety
requirements before, during and after work has been carried out. You are required under the Australian Workplace Health
and Safety Act to notify the owner or operator of any unsafe conditions or
possible premature failure of hoses or associated fittings.
Care must be taken to avoid oil spills. Appropriate caps and plugs must be fitted and
drip trays used where possible, in order to minimize spills. When spills occur, it is necessary to use
rags or an approved oil absorbing material to ensure that the oil is contained and removed.
Note: It is an
offence against Australian Environmental legislation to allow oil to be introduced into
the storm water drainage system. Under
no circumstances may spilled oil be flushed or dumped into gutters or storm
water drains.
This course is one of the major sections in the “Mobile Hose Fixers and Hydraulics Operators Folder" which is a
guideline to assist you in marketing yourself as a Mobile Hose Fixer, It outlines “on the
job” procedures, and gives practical advice on hose making. You may, however, come across unusual
situations requiring innovative solutions.
Using your initiative to resolve these situations will be required, and
will help you to become a better Mobile Hose Fixer.
You must always adhere to all safety procedures, and ensure that checks
are carried out under working conditions.
Your Workplace Safety Policy
Safety – General
Correct Attire
Try to always wear the Mobile Hose Fixers uniform.
Black Cotton Cargo Pants (these pants give you room to move and lots of pockets), Black Cotton Short Sleeved Shirt, Black Cotton or Bamboo Socks and Black Steel Capped Safety Boots. As well as looking professional, the uniform of good quality and can stand a great deal of rough punishment. Make sure you have enough uniform sets We recommend 5 sets changed Daily to suit your needs. A Reflective or high-visibility vest or clothing is now mandatory on most work sites.
Safety Footwear
Safety footwear with Steel Toe Caps is a must and should be worn at all times when carrying out repairs either on-site, or in the workshop. Safety footwear comes in a range of styles and a variety of materials. Remember, the majority of spillage is oil, so the material of the footwear should be oil as well as slip resistant.
Safety Spectacles
Contrary to what most people think in regard to safety spectacles, is that you should only wear them when grinding, drilling, buffing etc, you should in fact wear them when dealing with anything high pressure whether it is static or fluctuation pressures.
Safety Hats
Safety Hats or hard hats are to be worn where instructed, usually at a construction site or where a sign displays the use of safety hats. Safety Hats will also protect your head and scalp from UV rays from the sun as well as from low obstacles that you need top duck under. The site Safety Officer may question you if you are not wearing a hat, and can actively order you off the site.
Dehydration
Just about every new guy we have employed has suffered from the effects of dehydration because they ignored our instructions on taking ample drinking water with them to a job.
You will for the most part be working outside on an open exposed site under the sun, in the wind and usually in close proximity to hot equipment, engines and pumps. As this job can at times be physically quite demanding, the lack of available drinking water can lead to strange side effects such as lack of concentration, dizziness and nausea, if these effects are ignored can result in mistakes, and or even deadly accidents.
Make sure you take with you to each job at least 3 liters of cool clean drinking water. If you perspire a lot you make also want to consider taking an electrolyte supplement to replace essential salts and minerals perspired out.
Ear Protection
The wearing of hearing protection may be a mandatory safety requirement in some workplaces, or at specific locations within a workplace. In most instances appropriate signage will alert you to this requirement.
However, even when hearing protection is not required, consideration should be given to wearing hearing protection in workplaces that do generate excessive noise.
This would be more common in factory situations where injection molding or stamping machine were in operation.
On construction sites, it would be wise to wear some sort of hearing protection if you were working close to drilling machines or rock breakers for some length of time.
Welding Goggles
Welding Goggles should be used at all times when electric or gas welding. Similar to safety spectacles, they are to be used to protect your eyes. Irreversible damage can be caused to eyes due to the brightness of the light that is radiated when welding
Vehicle
Maintenance
The mobile hose operator, must maintain a regular service
program for the vehicle regardless of its age. This ensures that the vehicle remains reliable (paramount to business
success), and safe to operate.
In
addition to regular mechanical servicing, the van operator must also check the
condition of tyres, wiper blades, bulbs, fluid levels, reverse beepers etc. in
accordance with the manufacturer’s recommendations.
Specific information should be available in
the vehicle’s owner’s manual. Please see vehicle weekly Inspection Sheet in appendix.
Types of Vehicles to Use
We have tried and used, Utes, Vans and Light Trucks between 3.0 to to 4.5 tones Gross Vehicle Mass.
Based on our experience the most reliable, user friendly and available space has come from Using Light Trucks with swing up doors on all sides. They usually are built stronger can carry more weight and are more cost effective.
We choose to use Isuzu Trucks mainly because in Australia they have market share and therefore parts are readily available at a reasonable prices, but more importantly because we have found that with regular maintenance, parts are rarely required other than the mandatory consumables such as oil and air filters, tires, brake pads or shoes and the occasional starter motor.

Safety On-Site
Having the correct safety equipment is essential as
mentioned in the previous section.
Further to this; and depending on the situation or the job which is
being carried out by you, it may be necessary to check a few items before
proceeding with the actual job. For your personal safety, complete a site
assessment prior to beginning any tasks. Please see our compact site checklist.
Position
of the Vehicle
Always try to position the vehicle as close as
practical to the work-site, without interfering with other people or their
workplaces. If in doubt, ASK!
Always try and position your vehicle so that when the doors open they provide shade and protection from direct sunlight.
In windy, dry and dusty conditions (hot or Cold) try and use the vehicle to protect you and the job you are working on from these negative elements.
Safety
Regulations
When entering or working on-site, observe all safety
regulations, both inside of buildings and outside on construction sites. This would include all speed limits and road
signs etc. If in doubt or an unfamiliar
site, it would pay to call in at the office or seek directions from the
appropriate persons.
Safety
at the Machine
In all instances avoid working on
a machine whilst it is in operation, or the motor is running. It may be necessary for the operator to work
his controls to correctly diagnose a fault or leak. Once satisfied, the operator should turn
everything OFF and vacate the machine or vehicle whilst you are
working. Many injuries and fatalities
have occurred because of a misunderstanding.
Never start a machine before you are 100% sure of how to turn it
off. Anything could happen. An arm could drop and injure somebody or
worse. Also once you start the machine,
it doesn’t take long to pump all the oil out of a blown hose. Then you’ve got all sorts of dramas.
Pressure
Tanks
Some machines that you will work
on, predominantly earth moving machines, may have a pressurized hydraulic
tank. If so, your initial procedure
before undoing hose fittings will be to release the tank pressure. Usually the operator is aware of the
procedure. However if in doubt, find out
before proceeding. As well as being
embarrassing, it can be a dangerous situation undoing a pressurized fitting.
Feeling
for a Leak
When diagnosing and more
specifically looking for a leak in a hose, it may become difficult in locating
because of the different circumstances surrounding the position of the
hose. If so, resist using your hand to
feel for a fault on the hose, it can cause you injury which in turn could
result in having you laid off work and hence, no income.
Cracking a Hose
At the point of actually starting
to undo the hose fitting or “cracking” the hose, it is imperative that you are
confident that it is not going to cause a hazardous situation to you, or cause damage
to the machine or surrounding fixtures etc.
·
If in doubt check with a person who does know before proceeding.
·
Fatalities have occurred due to the fact that this has
been overlooked.
·
In some cases it may be necessary to remove several
hoses or hose fittings, and because these hoses are not at fault, they may
still be holding pressure in which case you may have to chock or secure a
certain part or parts of a machine before proceeding.
·
Please ensure that all hoses that have been
disconnected are free from any blockages and or check valves.
·
Ensure that both ends are free from plugs and caps
before cutting, re-ending or shortening.
·
Ensure all parts/linkages are secured properly/resting
securely on the ground
Pinhole
Leaks and Oil Injection Injuries
Probably the most common injury associated with hydraulic
systems is the result of pinhole leaks in hoses. These leaks are difficult to
locate.
A person may notice a damp, oily, dirty place near a hydraulic line.
Not seeing the leak, the person runs a hand or finger along the line to find
it.
When the pinhole is reached, the fluid easily can be injected into the skin
as if from a hypodermic syringe. Immediately after the injection, the
person experiences only a slight stinging sensation and may not think much about
it. Several hours later, however, the wound begins to throb and severe pain
begins.
By the time a doctor is seen, it is often too late, and the individual
loses a finger or entire arm. Unfortunately, this kind of accident is not
uncommon. To reduce the chances of this type of injury, run a piece of wood or
cardboard along the hose (rather than fingers) to detect the leak (see Figure
1).
 |
Figure 1 The Dangers of Oil Injection
and how to safely check for Leaks |
Removing
Welded Joints
When at any stage you apply heat
to a fitting which still has the remains of a hose attached, do it with care
and always have a hose tail or fitting secured when applying heat, as it will
blow off with a force strong enough to cause injury if struck.
Suction
Hose !
Although suction hose is only
used at a low or negative pressure and doesn’t appear to create a safety
threat, it is the makeup of the hose which can cause serious injury. Suction hose, because
of its application, can in some cases collapse which will cause a
restriction. To overcome this, two
spring steel strands are moulded into the hose.
The unsafe condition arises when the hose is cut. The wire strands are exposed and tend to
protrude outwards. In all cases the wire
is to be made safe by cutting it behind the end of the hose end.
Correct
Tools for the Job
As well as selecting the correct
spanners for a certain size hose tail of swivel nut, or the correct size welding tip, or
even the correct jaws for the crimping machine, along with the correct tools
comes the associated safety equipment.
e.g. Welding: Gloves, Goggles, Boots
and Clothes
Grinding: Gloves, Safety
Spectacles, Boots, Clothes and Hearing Protection
Dismantling: Clothes, Boots, Gloves and Safety
Spectacles.
Completion of
Job
Along with checking the job for leaks, and hose positioning,
point out if necessary any unsafe condition to the operator. If it’s out of your control to make safe,
then as well as telling the operator, you should make a note of it on your
docket. Any extra materials, equipment
or oil spillage should be removed or cleaned up; or the necessary arrangements
made for the removal and clean up. The
bottom line is to cover yourself, especially where safety is involved.
Business Safety
Protect your business and that of the remainder of the
team by completing the job so that the machine you’ve worked on is safe. E.g., If you haven’t cleaned the dirt out of
a hose or if you put dirty oil back in the tank, a number of failures could
occur. Make sure that your future work
with that customer is safe.
Workplace Harassment
As your company grows and you add team members your
company should strive to maintain an environment of mutual respect, free of all forms
of harassment. Inappropriate behaviour, such that gives offence; makes employees
feel intimidated or humiliated at work; negatively impacts on employee morale
or interferes with work performance, will be considered and treated as
harassment. Furthermore any or all discrimination based on sexual orientation,
ethnicity, racial, religion, disability or age will be considered harassment.
Scope
This workplace
harassment policy applies to all employees or contractors, public visitors,
clients and anyone else whom employees come into contact with during the
discharge of their professional duties.
Policy elements
Harassment
may include but is not limited to bullying, intimidation, insults, malicious
gossip, victimisation etc. Employees should not be obliged to tolerate any form
of misconduct that undermines the integrity of their relationship to the
company or creates a hostile work environment.
What is
the definition of harassment in the workplace?
While it is impractical list all
occasions which would constitute harassment, we nonetheless provide some
indicative examples:
·
Sexual harassment
·
Discriminatory harassment
·
Unwelcome sexual advances,
·
Requests for sexual favors or coerced sexual acts
·
Derogatory comments on a person’s ethnic
heritage/religious beliefs
·
The display of objects which are degrading to
members of a particular group
If an
employee experiences or witnesses harassment by any other employee, customer or
vendor, they are obliged to report the incident as soon as possible to their
immediate supervisor or to the Human Resources department. All reports will be
discreetly and confidentially investigate to determine whether harassment has
occurred.
Grievance Procedure
All your supervisors and managers are responsible for ensuring that policies designed to
prohibit harassment in the workplace are applied at all times and that all
procedures and practices are free of discrimination. All staff are obliged to follow legal
guidelines and company principles.
In cases
when rules are adjudged to have been violated, employees can address the
offender directly. If the issue is not resolved the complainant can report it
to the Human Resources department or their immediate supervisor. The report
will be investigated in a timely fashion and all parties listened to. The
employee that suffered the offense will be protected against any further form
of harassment or victimization.
Disciplinary Consequences
Any such
actions, when determined, will bring prompt disciplinary steps against the
offending party, including counseling, warnings, suspensions or termination.
Hydraulics
 |
| Damaged gear from skip bin truck pump caused by over speed and heat. |
Hydraulics in general like valves, valve banks,
cylinders, motors and pumps etc. are an area that you should consider expanding into and as such there will be times when you will be completely out
of your level of expertise, experience and comfort zone. In these situations if
you are unsure just say so, but also advise the client that you will call the
main service centre and ask for backup or advice.
A hydraulic system may be simple and easy to follow,
or on the other hand, with a number of assorted valves installed in a system,
it can be very complicated as well as expensive to repair. It may be that you feel obliged to help the
customer by removing hydraulic parts which may be at fault. However, you must know your limitations.
Try and build alliances with companies that deal in
hydraulics or specialise in one brand of machine only.
As you gain experience, so does your ability
to diagnose faults in a hydraulic system.
If you can confidently refer someone, as well as helping the customer,
you are giving the hydraulics person an opportunity to carry out a repair. This referral should be reciprocal and
hopefully a “win – win” situation.
Hose And Fittings
 |
| 5 Short Hose Assemblies with BSPP Female Swivel Ends |
A hose may be made up from many different materials
and constructions depending on the specific application and environment. It consists of a tube to carry liquid or gas,
a reinforcement to enable the tube to use high pressure, and a cover to protect
the reinforcement and the tube from the environment.
Basic Hose Construction
There are a number of different hose construction each with their own special or general recomended applications we use the common SAE100R** designations as they are widely used in the Australian Hydraulics Industry.
Please be aware that the higher the SAE100R** number does not always represent the higher the pressure or specification of the hose.
Mobile Hose Fixers And Hydraulics use the following main types of SAE Designated Hose Construction.
100R1AT, 100R2AT, 100R4, 100R5, 100R7, 100R12, 100R13, 100R14, 100R15, 100R19
Types of Hoses
Because of the different substances as well as the
range of different pressures hoses endure, so too, the range of different hose
constructions. These hose constructions
can vary from your common push on low pressure, single cotton braid type hose, to
ultra high pressure multi-spiral type hoses.
Stainless steel convoluted Teflon hose to six inch stainless steel
delivery hose. These different sizes and
types of hoses are illustrated below.
The most common hose used in hydraulic oil transfer as
a pressure hose, is steel wire reinforced synthetic rubber hose.
Specialty hoses, such as chemical transfer
hose, may have to be sourced for specific uses.
If so, refer to a hose compatibility chart or chemical resistance chart in
your Catalog. As you become more
experienced, the more conversant you will become with regard to the best and
most practical hose to use for a particular job.
Hose Sizes
All hoses, regardless of size, pressure rating or material, is measured and identified by its inside diameter (I.D.). These measurements are in imperial measurement, and are generally in increments of 1/16 inch. In the case of SAE Hydraulic hose, measurement (although measured in 1/16 inch increments) is referred to in a code size. These code sizes are also known as “dash” sizes.
Hose Size and Dash Sizes
Hose sizes are expressed in terms of 1/16 inch increments. That is, size 04 = 4/16” I.D. or ¼”; size
Full Inside Diameter. – Normally used in high pressure rubber covered hose.
Tube Size
Tube size is measured on The Outside Diameter (O.D.), and should be taken into account when replacing with hose. In some cases hose is manufactured to cater for the I.D. of the tube size. Examples of these are:
· Air conditioning hose
· Steel Seamless tubing
· Air brake hose
· Teflon hose
Hose Reinforcement
Pressures may vary from low pressure or a vacuum, to extremely high pressure. The pressure will determine the amount and type of reinforcing. The reinforcing varies from a cotton or nylon braid for low pressure, to multi-spiral high tensile stainless steel reinforcing for ultra-high pressure applications. Flexibility and size must be considered for a given pressure range. The layers of reinforcing in some hoses are separated by a layer of rubber or other materials.
Note: Most hoses have a 4:1 safety margin. E.g., 5000 psi working pressure : 20000 psi burst pressure.
BRAID AND SPIRAL REINFORCEMENTS
Single Fabric Braid
Single Wire Braid
Double Wire Braid
Multi Spiral
Hose Selection
When it is necessary to select a hose for a particular application, the following information will be required for the correct selection:
1. Operating pressure
2. Flow Rate
3. Fluid or substance to be carried by the hose
4. Temperature range of fluid or substances
5. Ambient temperature of surrounding conditions
1. Operating Pressure
The operating pressure determines the hoses reinforcement. The working pressure or operating pressure should be equal to at least any peak pressure the hose may encounter.
2. Flow Rate
The flow rate determines the inside diameter of the hose. When replacing a hose, always try to select a hose equal to the one you are replacing. Avoid replacing a hose which is smaller in diameter. If at any stage you have not got the correct diameter hose for the replacement, go larger in diameter than smaller.
3. Fluid to be Carried by the Hose
This will help determine the hose tube material. Refer to the compatibility chart in the catalogue and select a suitable hose and fitting material, compatible with the fluid to be carried.
4. Temperature Range of Fluid or Substance
This will help to determine the hose tube material. Refer to the hose section of the catalogue and select a hose that will suit the fluid temperature range encountered.
5. Ambient Temperature and Type of Atmosphere
This will help determine the material used in the hose outer cover, which is normally equal to that of the hose tube listed in the hose section of the catalogue
Caution: The maximum flow rate of the hydraulic pump in a system may not be the maximum flow to be carried by the hose. For example; a hydraulic lifting cylinder may be allowed to descent rapidly under the influence of its load, causing a much higher rate of flow in the hoses connected to the cylinder than that encountered during the lifting cycle when only the pump flow rate is seen.
Hose Identification
Identifying hoses for a specific purpose becomes easier as the more experienced you become as a Hose Fixer. Along with identifying the hose by its size (I.D. measurement) hoses can be identified by the cover colour and reinforcing. In many cases all information which is relevant for a repair is written on the hose cover, (i.e. type, working pressure, size etc.)
Hoses that are used for specific purposes (petroleum, gas etc.) have standard markings so that they can be identified easily, and there is less chance of a mistake being made.
Low pressure, or push on hose, comes in a variety of types for a number of different purposes. If you are in doubt as to whether the hose selected is suitable, ask or refer to a hose chart.
Attention to this detail is paramount where spillage could cause contamination to equipment or the environment. Chemical transfer hose is sometimes identified by a helical strip on a black cover. Another hose which can be identified by a coloured strip is suction hose. This is larger in diameter, and holds its form by two (2) spring wires vulcanised into the rubber. As mentioned previously, experience plays a big part in hose replacement. If in doubt, use a hose that would adequately do the job.
Although the service van has a range of hoses, the most common hoses used are wire braided and multi-spiral hoses as shown in the diagrams and specifications below.
Hose Colours
Hoses may be found in a number of colours and may
include a coloured lateral trace. The
most common colours include red, blue, grey and black. In the past these colours were used to
identify various attributes (including pressure and temperature ratings),
however this is not usually the case with modern hoses. The most common colour in current use is
black.
Hose Inner Tube
The hose inner tube is made up from a number of
different sizes and varied materials.
Depending on what substance and in what volume per minute (flow) is being transferred, will depend on the
inner tube material and size, and in some cases the covering also. A particular hose inner tube may be compatible
to a number of different substances, and if in doubt as to the compatibility,
reference should be made to the chemical resistance chart, Appendix 2.
Below is a list of the more common hose inner
materials.
·
Neoprene (synthetic rubber)
·
Nitrile
·
Teflon
·
Nylon
·
Polyester
Below are examples of different types of hoses with
different types of inner tubes.
