SAFETY
PREVENT THE BUCKET FROM HITTING
THE DITCH.
Be careful that the bucket will not hit the walls
of ditch or the bank during swinging operation.
This is likely to occur when conducting digging
and dumping alternately.
Move the bucket slowly.
NEVER SWEEP WITH THE BUCKET.
Avoid sweeping the bucket like a broom in
order to level off ahead of machine. This
causes side strains and wear on the boom,
arm, and bucket.
DO NOT MOVE THE ATTACHMENTS TO
THE EXTREME ENDS OF THE STROKE.
If the rod is extended to the stroke end of the
cylinder, the shock applies a large force to the
cylinder, which may cause a damage to the
boom or arm.
Operate the machine without moving the
cylinder to the extreme end of the stroke.
It is recommended to operate the attachments
near the stroke end of the cylinder.
USE AN EXCLUSIVE MACHINE TO DIG OR
BREAK EXTREMELY HARD MATERIALS.
Do not use the bucket to dig or break very
hard materials like concrete. This will cause
damage to the machine.
