VARIABLE SPEED CONTROLLED
TRIGGER SWITCH
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).
FORWARD/REVERSING
LEVER & TRIGGER LOCK
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. 6). 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 (Fig. 6).
For reverse rotation move the lever to the far
right (Fig. 6). To activate trigger lock move
lever to the center off position.
Do not change direction
of rotation until the tool
comes to a complete stop.
Shifting during
rotation of the chuck can cause damage to
the tool.
