For drilling in wood, metal or plastic materials, depress
the lock button and rotate the action mode changing
knob to the symbol. Use a twist drill bit or wood bit.
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.
