retaining the pin rolls. Add grease to the
pin rolls.
Remark:
●

5.8.2.7 Bucket clearance - adjust
The bucket linking clearance must be readjust-
ed after your machine has been operated for
a period of time. When the linking clearance
is excessively large or small, it is necessary to
install or remove the spacer.
Place the work equipment
fi
rmly before ad-
justing bucket clearance. Stop the engine
and engage the hydraulic lockout control.
If the hydraulic lockout control is free,
unexpected movement of the work equip-
ment could cause severe accident.
