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.
For reverse rotation move the lever to the far
right. 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.
GEAR SHIFTING
Your tool is equipped with two separate gear
ranges, low gear and high gear. 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 or low position (Fig. 1).
ATTENTION: If your tool appears to be
running, but the chuck will not turn, check to
make sure the gear shifting switch is pushed
fully into desired setting.
ADJUSTABLE CLUTCH
Your tool features 26 clutch settings. Output
torque will increase as the clutch ring, is
rotated from 1 to 25. The drill ",lll_ " position
will lock up the clutch to permit drilling and
driving heavyduty work, and also enables bits
to be changed quickly and easily in the
keyless chuck (Fig. 7).
DRILL/HAMMER DRILL SELECTOR RING
The selector ring allows the tool to be set for
various drilling/hammer drilling applications.
Rotate the selector dial right or left
depending on the below applications (Fig. 7).
Drill only action: For drilling in woods, metals,
plastics or other non concrete materials.
Drill with hammer action: For drilling in
concrete, asphalt, tile or other similar hard
materials. The hammer drill position overrides
the clutch for hammer drilling.

BRAKE
When the trigger switch is released it
activates the brake to stop the chuck quickly.
This is especially useful in the repetitive
driving and removal of screws.
BUILT IN WORK LIGHT
Your tool is also equipped with a light that turns
on automatically when the switch is activated,
for better visibility when drilling/driving (Fig. 1).
