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.

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

the trigger can not be released.

REVERSING SWITCH BUTTON

The reversing switch button is located above the trigger switch and is used to reverse rotation of the bit. For forward rotation, (with the chuck pointed away from you) move button to the far left. For reverse rotation move the button to the far right.

!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.

HIP CLIP

Your tool is equipped with a hip clip that allows you to conveniently attach your drill to your belt, (Fig.1) This feature will allow you to have both hands free when climbing a ladder or positioning material to be fastened.

CHUCK KEY & STORAGE AREA

Keyed models are equipped with a chuck key that is conveniently located on the cord protector where it is always handy and unlikely to get lost or misplaced.

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. 2).

KEYLESS MODELS

To tighten, hold the chuck collar firmly with one hand and securely tighten the chuck sleeve with the other hand (Fig. 3).

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

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