Operating Instructions

TRIGGER CONTROLLED VARIABLE SPEED Your tool is equipped with a variable speed trigger switch. The tool speed can be controlled from minimum to maximum nameplate rated RPM by the pressure you apply to the trigger. Apply more pressure to increase the speed and release pressure to decrease speed (Fig. 1).

"LOCK-ON" BUTTON

The "Lock-ON" button, located in the handle of your tool allows for continuous operation at maximum RPM without holding the trigger.

TO LOCK TRIGGER "ON": squeeze trigger, depress button and release trigger.

TO UNLOCK THE TRIGGER: squeeze trigger and release it without depressing the "Lock- ON" button.

If the “Lock-ON” button is continuously being depressed,

the trigger can not be released.

FORWARD/REVERSING LEVER &

TRIGGER LOCK

Your tool is equipped with a forward/reversing lever and trigger lock located above the trigger (Fig. 1). This lever was designed for changing rotation of the chuck, and for locking the trigger in an“OFF” position to help prevent accidental starts. For forward rotation, (with the chuck pointed away from you) move 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.

!	CAUTION	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.

PRESET SPEED ADJUSTING DIAL

This feature enables you to preset the trigger at desired speeds by rotating the dial on the trigger to a higher or lower setting. Regardless of the pressure applied on the trigger, the tool will not operate any faster than maximum speed setting selected.

MODE SELECTOR SWITCH

The mode selector switch allows the tool to be set for various drilling applications. Slide the switch right or left depending on the below applications (Fig. 2).

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.

INSERTING BIT

For small bits, open jaws enough to insert the bit up to the flutes. For large bits, insert the bit as far as it will go. Center the bit as you close the jaws by hand. This positions the bit properly, giving maximum contact between the chuck jaws and the bit shank.

KEYED MODELS

To tighten chuck, insert key into each of the three key holes in succession and tighten firmly. The chuck can be released by using one hole only (Fig. 3).

KEYLESS MODELS

To tighten, hold the chuck collar firmly with one hand and securely tighten the chuck sleeve with the other hand (Fig. 4).

! WARNING	To prevent friction burns, or
	possible hand injury, do not

loosen or tighten the chuck by using the power of the drill.
