OPERATION

TO ADJUST DRILLING OR HAMMER MODE

See Figure 16.

To adjust hammer drill to drilling or hammer operation, rotate mode selector in the direction of arrows as shown in Figure

16.For your convenience a hammer symbol and drill bit sym- bol have been molded into the selector.

WARNING:

Your hammer drill has not been designed for re- verse hammering. Reverse hammering may dam- age your drill.

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 mate- rials.

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 drill 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 pres- sure 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 ma- sonry impact bits when drilling holes in brick, tile, concrete, etc.

Turn mode selector on hammer drill to hammer mode.

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.
