Hold the tool firmly with one hand on the grip and the

other hand on the bottom of the battery cartridge to

control the twisting action.

Hammer drilling operation

CAUTION:

• There is a tremendous and sudden twisting force

exerted on the tool/bit at the time of hole break-

through, when the hole becomes clogged with chips

and particles, or when striking reinforcing rods

embedded in the concrete.

First, turn the action mode changing ring so that the arrow

on the tool body points to the marking. The adjusting

ring can be aligned in any torque levels for this operation.

Be sure to use a tungsten-carbide tipped bit.

Position the bit at the desired location for the hole, then

pull the switch trigger. Do not force the tool. Light pressure

gives best results. Keep the tool in position and prevent it

from slipping away from the hole.

Do not apply more pressure when the hole becomes

clogged with chips or particles. Instead, run the tool at an

idle, then remove the bit partially from the hole. By

repeating this several times, the hole will be cleaned out

and normal drilling may be resumed.

Blow-out bulb (Optional accessory)

(Fig. 11)

After drilling the hole, use the blow-out bulb to clean the

dust out of the hole.

Screwdriving operation (Fig. 12)

First, turn the action mode changing ring so that the arrow

on the tool body points to the marking. Adjust the

adjusting ring to the proper torque level for your work.

Then proceed as follows.

Place the point of the driver bit in the screw head and

apply pressure to the tool. Start the tool slowly and then

increase the speed gradually. Release the switch trigger

as soon as the clutch cuts in.

CAUTION:

• Make sure that the driver bit is inserted straight in the

screw head, or the screw and/or bit may be damaged.

NOTE:

• When driving wood screws, predrill pilot holes to make

driving easier and to prevent splitting of the workpiece.

See the chart.

Drilling operation

First, turn the adjusting ring so that the pointer points to

the marking. Then proceed as follows.

CAUTION:

• Pressing excessively on the tool will not speed up the

drilling. In fact, this excessive pressure will only serve

to damage the tip of your bit, decrease the tool

performance and shorten the service life of the tool.

• There is a tremendous force exerted on the tool/bit at

the time of hole break through. Hold the tool firmly and

exert care when the bit begins to break through the

workpiece.

• A stuck bit can be removed simply by setting the

reversing switch to reverse rotation in order to back

out. However, the tool may back out abruptly if you do

not hold it firmly.

• Always secure small workpieces in a vise or with a

similar hold-down device.

• If the tool is operated continuously until the battery

cartridge has discharged, allow the tool to rest for

15 minutes before proceeding with a fresh battery.

Drilling in wood

When drilling in wood, the best results are obtained with

wood drills equipped with a guide screw. The guide screw

makes drilling easier by pulling the bit into the workpiece.

Drilling in metal

To prevent the bit from slipping when starting to make a

hole, make an indentation with a center-punch and

hammer at the point to be drilled. Place the point of the bit

in the indentation and start drilling.

Use a cutting lubricant when drilling metals. The

exceptions are iron and brass which should be drilled dry.

MAINTENANCE

CAUTION:

• Always be sure that the tool is switched off and the

battery cartridge is removed before attempting to

perform inspection or maintenance.

• Never use gasoline, benzine, thinner, alcohol or the

like. Discoloration, deformation or cracks may result.

Replacing the carbon brushes (Fig. 13)

Replace when they wear down to the limit mark. Keep the

carbon brushes clean and free to slip in the holders. Both

carbon brushes should be replaced at the same time. Use

only identical carbon brushes.

Use a screwdriver to remove two screws then remove the

rear cover. (Fig. 14)

Raise the arm part of the spring and then place it in the

recessed part of the housing with a slotted bit screwdriver

with a slender shaft or the like. (Fig. 15)

Use pliers to remove the carbon brush caps of the carbon

brushes. Take out the worn carbon brushes, insert the

new ones and replace the carbon brush caps in reverse.

(Fig. 16)

Make sure that the carbon brush caps have fit into the

holes in brush holders securely. (Fig. 17)

Reinstall the rear cover and tighten two screws securely.

To maintain product SAFETY and RELIABILITY, repairs,

any other maintenance or adjustment should be
