Operating Instructions
VARIABLE SPEED CONTROLLED
TRIGGER SWITCH
Your tool is equipped with a variable speed trigger switch. The tool speed can be controlled from the minimum to the maximum nameplate RPM by the pressure you apply to the trigger. Apply more pressure to increase the speed and release pressure to decrease speed. This accurate speed control enables you to drill without center punching. It also permits you to use as a power screwdriver. Bits are available for driving screws as well as running bolts and nuts (Fig. 1).
FORWARD/REVERSING LEVER &
TRIGGER LOCK
Your tool is equipped with a forward/reversing lever and trigger lock located above the trigger (Fig. 2). This lever was designed for changing rotation of the chuck, and for locking the trigger in an “OFF” position
to help prevent accidental starts and accidental battery discharge. For forward rotation, (with chuck pointed away from you) move the lever to the far right. For reverse rotation move
the lever to the far left. To activate trigger lock move lever to the center off position.
Do not change direction of ! CAUTION rotation until the tool
comes to a complete stop. Shifting during rotation of the chuck can cause damage to the tool.
MODE SELECTOR SWITCH
The mode selector switch allows the tool to be set for various drilling/hammer drilling applications. Slide the switch right or left depending on the below applications (Fig. 1).
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.
GEAR SHIFTING
Your tool is equipped with two separate gear ranges, low gear and high gear.
Low gear provides
drilling speeds for heavy duty work or for driving screws.
High gear provides faster speeds for drilling lighter work.
Changing gears: Change gear position only with the motor at a complete standstill. To change gears rotate the gear selection lever. If you have difficulties changing from one gear to the other, turn the chuck by hand until the gears engage (Fig. 1).
AUXILIARY HANDLE
The tool must be supported with the auxiliary handle, which can be swiveled 360˚. To reposition and/or swivel the handle, loosen the hand grip, move the handle to the desired position along the barrel and securely retighten the hand grip (Fig. 1).
DEPTH GAUGE
Your drilling depth can be
Setting depth: After the auxiliary handle is installed, slide the depth gauge to desired depth and securely tighten wing knob.
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.
