MAINTENANCE
WHEN REQUIRED
REPLACING THE BUCKET TEETH
Replace the bucket teeth if the tooth points
are worn. Do not wait until the bucket is
damaged.
• Before performing maintenance or
repairs under the machine, lower all
moveable working equipment to the
ground or in the lowermost position.
• To prevent unexpected movement,
firmly secure the working equipment
when repairing or replacing the bucket
teeth or side cutter.
• When using a hammer, pins may fly out
or metal particles may be scattered.
This may lead to serious injury.
· If hard metal parts such as pins,
bucket teeth, side cutter or bearings
are hit with a hammer, wear protective
gear such as safety goggles and
gloves.
·
When hitting pins or bucket teeth,
always check that there is no one in
the surrounding area.
• Do not allow unauthorized personnel in
the work area while working.
WHEN REQUIRED
Replace the teeth if they are worn to 140
mm (5.5 in.).
