Clogging of spreader
Freezing or arching of the material inside the spreader can lead to poor spreading performance, but
complete blocking is unlikely to occur when using normal spreadable materials. The material inside the
spreader can be mixed with a shovel, which usually is enough to clear any blockage. Follow safe stopping
procedure before going near the spreader. Keeping the material protected from rain is important for efficient
operation. Mixing material with salt may reduce or prevent freezing. Never remove the protective grille from
the spreader, always use suitable tools. Also, do not hit the spreader against the ground to prevent
damaging the spreader.

Maintenance and service
Continuous maintenance of the spreader includes regular cleaning, monitoring the condition of rotating parts
and regular lubrication. Check the material left in the spreader and remove any rocks or clogged material. If
the spreader makes unusual noise, stop the spreader, empty it and check the mixing and spreader shafts as
well as the chain drive.
Ensure that the attachment is properly supported during all inspections, adjustments
or maintenance work. Ensure the support also when the spreader is mounted to the
loader; note that the loader boom and the rear lift device may move even if the
engine is not running.

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 pressurized, 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, which is
marked on the hoses. After the date marked on the hoses, they should be replaced with new ones.
