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.
