TO ADJUST DRILLING OR HAMMER MODE

See Figure 19.

To adjust drill to drilling or hammer operation, rotate mode

selector in the direction of arrows as shown in Figure 19. For your convenience a hammer symbol and drill bit

symbol have been molded into the selector.

_ WARNING: Your hammer drill has not been designed for reverse hammering. Reverse hammering may damage your drill.

SELECTOR

Fig. 19

We recommend that you use carbide-tipped bits and select hammer mode when drilling in hard materials such as brick, tile, concrete, etc.

We recommend that you select normal drilling mode when drilling with twist drills, hole saws, etc. in steel and soft materials.

WOOD DRILLING

For maximum performance, use high speed steel bits for wood drilling.

Turn mode selector ring on hammer drill to normal drilling action.

Begin drilling at a very low speed to prevent the bit

from slipping off the starting point. Increase the speed as the drill bit bites into the material.

When drilling through holes, place a block of wood behind the workpiece to prevent ragged or splintered edges on the back side of the hole.

Do not lock the trigger on for jobs where your hammer drill may need to be stopped suddenly.

METAL DRILLING

For maximum performance, use high speed steel bits for metal or steel drilling.

Turn mode selector on hammer driU to normal drilling action.

Begin drilling at a very low speed to prevent the bit from slipping off the starting point.

Maintain a speed and pressure which allows cutting without overheating the bit. Applying too much pressure will:

Overheat the drill;

Wear the bearings;

Bend or burn bits; and

Produce off-center or irregular shaped holes.

When drilling large holes in metal, we recommend that you drill with a small bit at first, then finish with a larger

bit. Also, lubricate the bit with oil to improve drilling action and increase bit life.

MASONRY DRILLING

For maximum performance use carbide-tipped masonry impact bits when drilling holes in brick, tile, concrete, etc.

Turn mode selector on hammer drill to

hammer mode. Rotate torque selector to drill position.

Apply light pressure and medium speed for best results in brick.

Apply additional pressure and high speed for hard materials such as concrete.

When drilling holes in tile, practice on a scrap piece to determine the best speed and pressure.
