Functional Description - Makita HR4001C Instruction Manual

5. Under normal operation, the tool is designed to
produce vibration. The screws can come loose
easily, causing a breakdown or accident. Check
tightness of screws carefully before operation.
6. 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.
7. Always be sure you have a firm footing.
Be sure no one is below when using the tool in
high locations.
8. Hold the tool firmly with both hands.
9. Keep hands away from moving parts.
10. Do not leave the tool running. Operate the tool
only when hand-held.
11. Do not point the tool at any one in the area when
operating. The bit could fly out and injure some-
one seriously.
12. Do not touch the bit or parts close to the bit
immediately after operation; they may be
extremely hot and could burn your skin.
13. Some material contains chemicals which may be
toxic. Take caution to prevent dust inhalation
and skin contact. Follow material supplier safety
data.
