produce vibration. The screws can come loose
easily, causing a breakdown or accident. Check
tightness of screws carefully before operation.

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-

8. Do not leave the tool running. Operate the tool
only when hand-held.
9. Do not point the tool at any one in the area when
operating. The bit could fly out and injure
someone seriously.
10. Do not touch the bit, parts close to the bit, or
workpiece immediately after operation; they may
be extremely hot and could burn your skin.
11. Some material contains chemicals which may be
toxic. Take caution to prevent dust inhalation and
skin contact. Follow material supplier safety data.
12. Do not touch the power plug with wet hands.
