Your tool is equipped with a variable speed
trigger switch. The tool can be turned "ON" or
"OFF" by squeezing or releasing the trigger.
The speed can be adjusted from the minimum
to maximum nameplate RPM by the pressure
you apply to the trigger. Apply more pressure
to increase the speed and release pressure to
decrease speed (Fig. 1).

After tool use, lock trigger in
“OFF” position to help prevent
accidental starts and accidental discharge.
Your tool is equipped with a forward/
reversing lever and trigger lock located above
the trigger (Fig. 3). This lever was designed
for changing rotation of the bit, and for locking
the trigger in an “OFF” position.
For forward rotation, (with chuck pointed
away from you) move the lever to the far left.
For reverse rotation move the lever to the far
right. To activate trigger lock move lever to
the center off position.
