Selecting the action mode

Rotation with hammering

Fig.5

For drilling in concrete, masonry, etc., depress the lock

button and rotate the action mode changing knob to the

symbol. Use a tungsten-carbide tipped bit.

Rotation only

Fig.6

For drilling in wood, metal or plastic materials, depress

the lock button and rotate the action mode changing

knob to the

symbol. Use a twist drill bit or wood bit.

CAUTION:

• Do not rotate the action mode changing knob when

the tool is running. The tool will be damaged.

• To avoid rapid wear on the mode change

mechanism, be sure that the action mode changing

knob is always positively located in one of the three

action mode positions.

Torque limiter

The torque limiter will actuate when a certain torque level

is reached. The motor will disengage from the output

shaft. When this happens, the bit will stop turning.

CAUTION:

• As soon as the torque limiter actuates, switch off

the tool immediately. This will help prevent

premature wear of the tool.

• Hole saws cannot be used with this tool. They tend

to pinch or catch easily in the hole. This will cause

the torque limiter to actuate too frequently.

ASSEMBLY

CAUTION:

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

battery cartridge is removed before carrying out

any work on the tool.

Side grip (auxiliary handle)

Fig.7

CAUTION:

• Always use the side grip to ensure operating safety.

Install the side grip so that the teeth on the grip fit in

between the protrusions on the tool barrel. Then tighten

the grip by turning clockwise at the desired position. It

may be swung 360° so as to be secured at any position.

Bit grease

Coat the bit shank head beforehand with a small amount

of bit grease (about 0.5 -1 g). This chuck lubrication

assures smooth action and longer service life.

Installing or removing the bit

Clean the bit shank and apply bit grease before installing

the bit.

Fig.8

Insert the bit into the tool. Turn the bit and push it in until it

engages.

Fig.9

If the bit cannot be pushed in, remove the bit. Pull the

chuck cover down a couple of times. Then insert the bit

again. Turn the bit and push it in until it engages.

After installing, always make sure that the bit is securely

held in place by trying to pull it out.

To remove the bit, pull the chuck cover down all the way

and pull the bit out.

Fig.10

Depth gauge

Fig.11

The depth gauge is convenient for drilling holes of

uniform depth. Loosen the side grip and insert the depth

gauge into the hole in the side grip. Adjust the depth

gauge to the desired depth and tighten the side grip.

NOTE:

• The depth gauge cannot be used at the position

where the depth gauge strikes against the gear

housing.

Dust cup

Fig.12

Use the dust cup to prevent dust from falling over the tool

and on yourself when performing overhead drilling

operations. Attach the dust cup to the bit as shown in the

figure. The size of bits which the dust cup can be

attached to is as follows.

Bit diameter

Dust cup 5 6 mm - 14.5 mm

Dust cup 9

12 mm - 16 mm

OPERATION

Hammer drilling operation

Fig.13

Set the action mode changing knob to the

symbol.

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.

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
