Operating Instructions

PADDLE CONTROLLED VARIABLE SPEED

SWITCH WITH “LOCK-OFF”

Your tool is equipped with a variable speed paddle switch with “Lock-OFF” feature. The tool speed can be controlled from minimum to maximum nameplate rated RPM by the pressure you apply to the paddle. Apply more pressure to increase the speed and release pressure to decrease speed.

TO UNLOCK SWITCH AND TURN TOOL “ON”: Pull the front portion of the paddle lever BACKWARD (toward the cord) then squeeze the paddle lever.

TO SWITCH TOOL “OFF”: Release pressure on the paddle lever. The switch is spring loaded and will return to “OFF” position automatically.

PRESET SPEED ADjUSTING DIAL

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

REVERSING SWITCH LEVER

The reversing switch lever is used to reverse rotation of the bit.

To use drill in "Forward" rotation move lever to left side of tool. To "Reverse" the rotation of the bit move the lever to the right side of the tool.

!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.

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.

DRILL CHUCK

! WARNING To prevent personal injury, always disconnect tool from

power source before installing or removing accessories.

REMOVING CHUCK

This drill is equipped with a special chuck that is internally attached to the drilling spindle and can only be removed and replaced by a BOSCH Service Center, as special tools are needed to disassemble the tool.

INSTALLING AND REMOVING

ACCESSORIES

When installing a drill bit, insert the shank of the bit well within the jaws of the chuck, but not further than the beginning of the drill bit flutes. Tighten the chuck collar by hand until the shank is firmly gripped in the jaws.

Continue tightening by inserting the chuck key provided into each of the three holes in the chuck body and turn key clockwise until secure. To remove bit, reverse foregoing procedure. Use only the chuck key provided or identical replacement key to tighten or loosen the chuck jaws.

Operating Tips

You will extend the life of your bits and do neater work if you always put the bit in contact with the work before pulling the trigger. During the operation, hold the tool firmly and exert light, steady pressure. Too much pressure at low speed will stall the tool. Too little pressure will keep the bit from cutting and cause excess friction by sliding over the surface. This can be damaging to both tool and bit.

DRILLING WITH VARIABLE SPEED

The trigger controlled variable speed feature will eliminate the need for center punches in hard materials. The variable speed trigger allows you to slowly increase RPM. By using a slow starting speed, you are able to keep the bit from “wandering”. You can increase the

speed as the bit “bites” into the work by squeezing the trigger.

DRIVING WITH VARIABLE SPEED

Variable speed drills will double as a power screwdriver by using a screwdriver bit in the drill mode. The technique is to start slowly, increasing the speed as the screw runs down. Set the screw snugly by slowing to a stop. Prior to driving screws, pilot and clearance holes should be drilled.

FASTENING WITH SCREWS

The procedure shown in (Fig. 2) will enable you to fasten materials together with your hammer drill in the drill mode without stripping, splitting or separating the material.
