Do not force the action mode change knob or do
•
not move it from
mode (or vise versa) at once. It may damage the
tool. When turning the knob from
mode to symbol mode (or vise versa), stop it
at symbol mode once. And rotate the chuck
clockwise (looking from the chuck side) half turn or
until it clicks. Then turn the knob to the desired
mode. If it is still difficult to turn the knob, rotate the
chuck again.
Torque limiter
The torque limiter will actuate when a certain torque
level is reached. The motor will disengage from the
output 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 pinch 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.
Hook
CAUTION:
Never hook the tool at high location or on
•
potentially unstable surface.

CAUTION:
Always use the side grip to ensure operating

safety.
Install the side grip so that the protrusions on the grip fit
in between the grooves 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 longer
service life.
