ton and rotate the change lever so that the pointer points to
the symbol. Use a tungsten-carbide tipped bit.
Rotation only
For drilling in wood, metal or plastic materials, depress the
lock button and rotate the change lever so that the pointer
points to the symbol. Use a twist drill bit or wood bit.
Hammering only
For chipping, scaling or demolition operations, depress the
lock button and rotate the change lever so that the pointer
points to the symbol. Use a bull point, cold chisel, scaling
chisel, etc.
CAUTION:
• Do not rotate the change lever when the tool is running.
The tool will be damaged.
• To avoid rapid wear on the mode change mechanism, be
sure that the change lever is always positively located in
one of the three action mode positions.
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.
