Check wheels
Check the condition of tyres and rims visually daily.
Do not use if there is visible damage on tires or rims.
If a tyre is punctured take the tyre to a professional
tyre shop. It may not be possible to repair all
punctures safely. Do not repair tyres yourself.
Check tyre pressure with a pressure gauge
whenever you suspect wrong pressure. Check the
tyre pressures at least monthly. Check tyre pressure
when heavy attachments and extra counterweights
are not attached.
Check that the tyre models are appropriate for the
loader model and listed on page 36. The load and
speed rating of the tyre and rim must be appropriate
for the loader model.
The correct tyre pressure depends on tyre model and
intended load. Refer to Chapter Technical
Specifications.
WARNING
Risk of loss of stability due to
tire failure - Never attempt to
repair a tyre by yourself.
The
loader is equipped with heavy duty
tyres that must only be repaired by
a qualified tyre technician.

Check the attachment and the
quick coupling plate
Check the locking of attachment and locking pins on
attachment coupling plate. Check both locking pins:
Both pins must move
easily and come through
the lower brackets of the
attachment.
To check the attachment
and any additional
coupling instructions for
individual attachments,
see the Operator’s
manual of the
corresponding
attachment.
The locking pins must return easily to their locking
position. Do not operate the loader if the coupling
pins do not lock down.
Clean the locking pins when cleaning the loader.
Move the locking pins regularly, even if you do not
change attachments regularly.
The quick coupling plate and its pin on top of it must
not be bent, cracked, or otherwise damaged.
Make sure that the attachment is locked, if an
attachment is mounted on the quick coupling plate.
Check the operation of the attachment, and position
of the hydraulic hoses of the attachment. Hoses must
not rub against sharp surfaces, or get stretched or
pinned when moving the loader boom and the
attachment. See also the operator's manual of the
attachment, see page 4.
Hydraulic attachment locking:
If your loader is equipped with hydraulic attachment
locking, check that both locking pins move up and
lower down completely by using the switch on the
dashboard. Do not operate the loader if the
attachment locking system pins do not lower down
completely.
Use the hydraulic locking periodically even if you
don't change attachments.
