Inspections after starting the
loader
16.
Check the movements of boom
The boom should move smoothly to all extreme
positions, when using it without an attachment.
If the telescopic function of the boom starts to
stick under load, add grease to the lubrication
points on top of the boom. Do not apply grease
directly on the inner boom as it will collect dirt
and cause wear. Extend the boom fully and
spray PTFE lubricant onto the inner boom.
If the wear pads are worn, there may be too
much play between the boom sections. If there is
noticeable play, adjust or replace the slide pads
of the boom.
If an attachment is fitted, check that the boom
moves smoothly within its normal operating
range.
Hydraulic hoses or electric cables must not get
pinched or stretched in any position of the boom
CAUTION
Risk of collision - Avoid moving
the attachment to a position
where it can contact the loader.
Some attachments may reach the
front tires, boom, or structures of
the loader when moving the boom
or tilting to the extreme positions.
Use any attachment only for its
intended use.

17.
Check drive control and steering
Check operation of pedals and steering. Pedals
must move freely and not get stuck or feel stiff.
Check that loader stops when not pressing the
drive pedals. Do not use the loader if the braking
performance is decreased, or if the loader
creeps.
Allow the loader to warm up and check steering.
When the engine is running, turning the steering
wheel should be easy. When the engine is off
the steering will work but it will need more effort.
There is a built-in backup steering that makes it
possible to turn the loader in case the hydraulic
flow to steering is interrupted.
If you notice any trouble with pedals, stopping of the
loader, creeping, or trouble with normal or back-up
steering, switch on the parking brake, shut down the
loader, and service the loader before continuing use.
18.
Test parking brake
Test the parking brake periodically.
1.
When the loader is running, switch on the
parking brake.
2.
Switch drive speed mode to slow.
3.
Press drive pedals. The loader must not move
when parking brake is on.
4.
Increase engine RPM and test the parking
brake to both front and rear directions.
If the loader moves when drive pedals are pressed,
stop using the loader. Service the brakes before
using the loader.
