Selecting action mode
CAUTION:
• Always set the knob fully to your desired mode
symbol. If you operate the tool with the knob
positioned half-way between the mode symbols,
the tool may be damaged.
• Do not rotate the action mode changing knob when
the tool is running under load. The tool will be
damaged.
• To avoid rapid wear on the mode change
mechanism, be sure that the action mode changing
knob is always positively located in one of the three
action mode positions.

For drilling in wood, metal or plastic materials, depress
the lock button and rotate the action mode changing
knob to the

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.
• Hole saws cannot be used with this tool. They tend
to pinch or catch easily in the hole. This 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.

Always use the side grip to ensure operating safety.
Install the side grip so that the teeth on the grip fit in
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 longer
service life.
