to drop the tool accidentally. If the hook is deformed or
hung from the wrong position, there is danger that the
hook will slip off and the tool will fall.

○ In making a through hole, the power tool sometimes
shakes violently when the workpiece is pierced, from
example. Be careful you are not hurt by the hook even
if such situation happens.

However, when drilling 6.5 mm or smaller holes, use a
metalworking drill bit.

MAINTENANCE AND INSPECTION

1. Inspecting the drill bits
Since use of an abraded drill bits will cause motor
malfunctioning and degraded effi ciency, replace the drill
bits with a new one or resharpening without delay when
abrasion is noted.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that
they are properly tightened. Should any of the screws be

The motor unit winding is the very "heart" of the power
tool. Exercise due care to ensure the winding does not
become damaged and/or wet with oil or water.
