▶ 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
accidentally turning the
tool "ON" when it is not being used, place
the reversing lever in the center trigger lock
"OFF" position. Unintended tool start, may
cause injury or property and tool damage.
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.
Your tool is equipped with a forward/
reversing lever and trigger lock located above
the trigger (Fig. 8). 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. 8).
▶ 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. 10).
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.
