Check tightness of screws carefully before

operation.

7. In cold weather or when the tool has not been
used for a long time, let the tool warm up for a
while by operating it under no load. This will
loosen up the lubrication. Without proper
warm-up, hammering operation is difficult.
8. Always be sure you have a firm footing.
Be sure no one is below when using the tool in
high locations.
9. Hold the tool firmly with both hands.
10. Keep hands away from moving parts.
11. Do not leave the tool running. Operate the tool
only when hand-held.
12. Do not point the tool at any one in the area
when operating. The bit could fly out and
injure someone seriously.
13. Do not touch the bit or parts close to the bit
immediately after operation; they may be
extremely hot and could burn your skin.
14. Do not operate
unnecessarily.
15. Some material contains chemicals which may
be toxic. Take caution to prevent dust
inhalation and skin contact. Follow material
supplier safety data.
