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. 7). 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. 7).
For reverse rotation move the lever to the far
right (Fig. 7). To activate trigger lock move lever
to the center off position.

GEAR SHIFTING

Your tool is equipped with two separate gear
ranges, low gear 1 and high gear 2. Low gear
provides high-torque and slower drilling speeds
for heavy duty work or for driving screws. High
gear provides faster speeds for drilling lighter
work. To change speeds slide switch, to the high
2 or low position 1 (Fig. 8).
ATTENTION: If your tool appears to be running,
but the chuck will not turn, check to make sure
the gear shifter is pushed fully into desired
setting.
