600 Series
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 110 ft-lb (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.
