7. Maintenance and Service
The attachment has been designed to be as maintenance free as possible. Continuous maintenance includes
regular cleaning and lubrication, and monitoring the condition of the attachment. Because of the crushing
hazard caused by lowering machine parts, all maintenance work must be done when moving parts have been
lowered down completely and the attachment is lowered flat against the ground.
DANGER
Risk of crushing - Never go under lifted attachment. Make sure the attachment is
properly supported during all maintenance work. Never go under a lifted attachment. The
loader boom may lower unexpectedly during maintenance causing serious injuries from
crushing or impact even when the loader engine is not running. All maintenance and
service must be performed when the attachment has been lowered down to a safe
position.
7.1 Inspection of hydraulic components
Check the condition of the hydraulic hoses and components when the engine has been turned off, system has
cooled down, and the pressure has been relieved. Do not use the equipment, if you have discovered a leak in
the hydraulic system of the attachment or the loader. Leaking hydraulic fluid may penetrate skin and cause
serious injuries. Seek medical attention immediately in case hydraulic fluid penetrates the skin. Wash any part
of body that has been in contact with hydraulic oil carefully with water and soap. Hydraulic fluid is also harmful
to the environment and any leak to the environment must be prevented. Repair all leaks immediately after
detecting them; a small leak can quickly grow into a big one. Operate the attachment only with type of
hydraulic oil that is accepted for use in Avant loaders.
DANGER
Risk of high pressure fluid injection
through skin - Release residual pressure
before maintenance.
Never handle hydraulic
components when the hydraulic system is
pressurised, since a fitting may break or
become loose and the released oil may cause
serious injuries. Do not use the equipment, if
you have discovered a fault in the hydraulic
system.
Check hoses visually for cracks or abrasions. If there are signs of leaks, to check a component, hold up a
piece of cardboard in the area where a leak is suspected. Do not use hands to search for leaks. Monitor the
wearing of the hoses and stop the use, if the surface layer of any hose has worn off. Check the routing of the
hoses; adjust the hose clamps to avoid abrasion to the hoses. The hoses have limited service life. Depending
on operating conditions all hoses must be inspected thoroughly no later than after 3 to 5 years of use, and if
required, they must be replaced with new ones.
Finding any fault means that the hydraulic hose or component must be replaced and the equipment must not
be used until it is repaired. Spare parts are available from your nearest AVANT retailer or authorised service
point. Leave the repair work to professional service technicians, if you don’t have adequate knowledge and
experience about hydraulic assemblies and how to perform the repairing safely.
Regularly clean the loader oil cooler core; refer to the operator's manual of the loader for
more instructions. Overheating oil decreases the power and affects the service life of the
hydraulic components of both the attachment and the loader.
