Service and maintenance instructions
Safety instructions for maintenance
• Stop the engine and let it cool down before
starting any service operation.
• Put the service support on the boom lift
cylinder when working under the boom.
• Install the frame lock when lifting the
machine, for instance when changing tyres
• Before working on the engine or
equipment, disconnect the battery.
Check hydraulic hoses and components only when the
engine is stopped and hydraulic pressure is released.
Repair all leaks as soon as you have noticed them,
because a small leak can quickly change into a big one.
Do not operate the machine if you have noticed faults
or leaks in hydraulic system. Leaking hydraulic fluid can
cause serious personal injuries and is harmful to the
environment.
Check hydraulic hoses for eventual cracks and wear.
Follow the wear of the hoses and stop operation if the
outer layer of any hose has worn out. If there are signs of
oil leakage, put a piece of cardboard under the probable
leakage place in order to find the leakage. If you find
a fault, the hose or the component must be replaced.
Contact your Avant dealer or service for spare parts.
If the loader is equipped with the smooth
drive option, a pressure accumulator is
fitted to the boom hydraulic circuit. Do not
disconnect any hydarulic component before
the accumulator has been isolated from the
circuit and the residual pressure has been
released.
Never handle pressurized hydraulic components, because ejection of high
pressure hydraulic fluid can cause serious injuries. Never use hands to search
for leaks. Do not operate the machine if you have noticed a fault in the hydraulic
system. Consult a doctor immediately if hydraulic fluid penetrates your skin.
The red service support of the
boom lift cylinder is located
at the tip of the boom, behind
the attachment coupling plate.
Make sure that the boom
stays up during maintenance
operations by putting the
service support on the lift
cylinder piston rod. Secure
the service support by locking
it on the piston rod with the
long screw that is on the
support.
Installing of service support and frame lock
The frame lock is located over
the articulation joint, under
the seat base, and is fastened
with a bolt.
The frame can be locked with
the red frame lock. This way
the loader frame stays straight
during e.g. transportation.
Install the frame lock in the
holes on the front and rear
frame and secure it with the
cotter pin.
