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.
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 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 Checking hydraulic components
Check the condition of the hydraulic hoses and components when the engine has been turned off 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.
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.
Also the metal structures of the attachment must be inspected regularly. Check visually for damages and
inspect the quick attach brackets and their surrounding area carefully. The attachment must not be used if it is
deformed, cracked, or torn.
Welding repairs are only allowed to be carried out by professional welders. When welding, only methods and
additives suited for steel used in bucket must be used. For more information about repairs contact your
nearest service point.
