500 Series Daily inspections and maintenance
4. Visual inspection of boom and other
metal structures for defects
Check the loader structures visually. Do not use the
loader if there is visible damage
• All pivot pins must be in good condition andsecure
secured in place.
• Make sure that the pivot pins are not worn and there is
no excessive slack in the joints. Worn pins lead to wear
and failure of the joints, only small slack is acceptable.
• The telescopic boom has slide pads that wear during
use. The telescopic inner part of the boom must not
move signicantly when manually handling it. If it is
necessary to adjust or to replace the slide pads, contact
your Avant service.
Risk of dropping of load - Check all
pivot pins. Check the tightness of the
locking screws of all pivot pins. If any
of them is loose, use thread locking
compound and tighten.
Metal structures of the loader
Discontinue use of loader and
contact Avant service in case the
steel structure of the loader gets
damaged. A faulty reparation, or
wrong methods and materials used
for reparation, can cause further
hazardous failures or damage the
loader.
In case the ROPS safety frame or the
FOPS canopy of the machine gets
damaged, the machine must be taken
to Avant service for service. It is not
allowed to repair the ROPS and FOPS.
5. Check and tightening of bolts, nuts
and fittings
Check tightness of bolts, nuts and hydraulic ttings
regularly. However, do not overtighten; tighten hydraulic
ttings only if necessary.
The tightening torque of the wheel nuts is 150 Nm.
Check the tightness of the pivot pin locking screws.
Tighten and use thread locker, if necessary.
Risk of dropping of load - Check all
pivot pins. Check the tightness of the
locking screws of all pivot pins. If any
of them is loose, use thread locking
compound and tighten.
Wheel nuts settle in during the rst
hours of use of the loader and may
become loose. Tighten wheel nuts
after rst 5 operating hours. Check
tightness of wheel nuts regularly.
6. Wheel check
Check the condition of wheels visually. Do not use if there
is visible damage on tires or rims.
Check tire pressure with a pressure gauge, when wrong
pressure is suspected. Check tire pressure, when heavy
attachments and extra counterweights are not attached.
The correct tire pressure depends on intended load.
Refer to Chapter Technical Specications.
Risk of loss of stability due to tire
failure - Never attempt to repair
a tire by yourself. The loader is
equipped with heavy duty tires that
must only be repaired by a qualied
tire technician.
