Safety Instructions
Whenever possible, use a lift or pit when working
beneath vehicle, in preference to jacking. Chock
wheels as well as applying parking brake.
Jacking
Always use the recommended jacking points.
Always ensure that any lifting apparatus has
sufficient load capacity for the weight to be lifted.
Ensure the vehicle is standing on level ground prior
to lifting or jacking.
Apply the handbrake and chock the wheels.
WARNING: Do not work on or under a vehicle
supported only by a jack. Always support the
vehicle on safety stands.
Do not leave tools, lifting equipment, spilt oil, etc.
around or on the work bench area. Always keep a
clean and tidy work area.
Brake shoes and pads
Always fit the correct grade and specification of
brake linings. When renewing brake pads and brake
shoes, always replace as complete axle sets.Brake hydraulics
Observe the following recommendations when
working on the brake system:
lAlways use two spanners when loosening or
tightening brake pipe or hose connections.
lEnsure that hoses run in a natural curve and are
not kinked or twisted.
lFit brake pipes securely in their retaining clips
and ensure that the pipe cannot contact a
potential chafing point.
lContainers used for brake fluid must be kept
absolutely clean.
lDo not store brake fluid in an unsealed
container, it will absorb water and in this
condition would be dangerous to use due to a
lowering of its boiling point.
lDo not allow brake fluid to be contaminated with
mineral oil, or put new brake fluid in a container
which has previously contained mineral oil.
lDo not re-use brake fluid removed from the
system.
lAlways use clean brake fluid or a recommended
alternative to clean hydraulic components.
lAfter disconnection of brake pipes and hoses,
immediately fit suitable blanking caps or plugs to
prevent the ingress of dirt.
lOnly use the correct brake fittings with
compatible threads.
lObserve absolute cleanliness when working
with hydraulic components.
Cooling system caps and plugs
Extreme care is necessary when removing
expansion tank caps and coolant drain or bleed
screws when the engine is hot, especially if it is
overheated. To avoid the possibility of scalding,
allow the engine to cool before attempting removal.
Air suspension system
Whilst working on the air suspension system, eye
protection must be worn at all times.
