Torque limiter
The torque limiter will actuate when a certain torque
level is reached. The motor will disengage from the out-
put shaft. When this happens, the bit will stop turning.
CAUTION:
• As soon as the torque limiter actuates, switch
off the tool immediately. This will help prevent
premature wear of the tool.
• Bits such as hole saw, which tend to pintch or
catch easily in the hole, are not appropriate for
this tool. This is because they will cause the
torque limiter to actuate too frequently.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the
tool.

between the protrusions on the tool barrel. Then tighten
the grip by turning clockwise at the desired position. It
may be swung 360° so as to be secured at any position.
Bit grease
Coat the bit shank head beforehand with a small
amount of bit grease (about 0.5 - 1 g).
This chuck lubrication assures smooth action and lon-
ger service life.
