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. Accessories are available for driving screws as well as running bolts and nuts.

INSTALLING SDS-plus®ACCESSORIES Clean the insert shank end of the accessory to remove any debris, then lightly grease with a light oil or lubricant

Insert accessory into the bit holder through the dust shield, while twisting and pushing inward until it locks automatically into place. Pull outward on the accessory to be certain it is locked into the bit holder (Fig. 2).

NOTE: The high efficiency available from the rotary hammers can only be obtained if sharp and undamaged accessories are used. The "cost" to maintain sharp and undamaged accessories is more than offset by the "time saved" in operating the tool with sharp accessories.

REMOVING SDS-plus®ACCESSORIES

Accessories may be hot after ! WARNING use. Avoid contact with skin

and use proper protective gloves or cloth to remove.

To remove an accessory, pull and hold locking sleeve backward and pull bit forward. All accessories should be wiped clean after removing.
