OPERATING INSTRUCTIONS

Installing or removing bit

Important:

Always be sure that the tool is switched off and

unplugged before installing or removing the bit.

Clean the bit shank and apply the bit grease provided to

it before installing the bit. (Fig. 1)

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

it engages. (Fig. 2)

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. (Fig. 3)

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. 4)

Selecting action mode

When selecting an action mode, first set the change lever

and the shift lever to the position shown in Fig.5. Then

proceed as follows.

Rotation with hammering (Fig. 6 & 7)

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

button and rotate the change lever so that the pointer

points to the h

symbol. Use a tungsten- carbide tipped

bit.

Hammering only (Fig. 6& 8)

For chipping, scaling or demolition operations, depress

the lock button and rotate the change lever so that the

pointer points to the

symbol. Use a bull point, cold

chisel, scaling chisel, etc.

Rotation only (Fig. 6 &9)

For drilling in wood, metal or plastic materials, rotate the

shift lever so that the symbol is aligned with the

pointer on the change lever. Use a twist drill bit or wood

bit.

CAUTION:

• Do not rotate the change lever and/or the shift lever

when the tool is running under load. The tool will be

damaged.

• To avoid rapid wear on the mode change mechanism,

be sure that the change lever and/or the shift lever is

always positively located in one of the three action

mode positions.

• The action mode cannot be changed directly from

“hammering only” to “rotation only” or from “rotation

only” to “hammering only”. First set the change lever

and the shift lever to “rotation with hammering” mode

position shown in Fig. 5. Then set them to the position

for “hammering only” or “rotation only”.

Bit angle

(when chipping, scaling or demolishing)

Important:

Always be sure that the tool is switched off and

unplugged before changing the bit angle.

The bit can be secured at 12 different angles. To change

the bit angle, depress the lock button and rotate the

change lever so that the pointer points to the

symbol.

Turn the bit to the desired angle. (Fig. 10)

Depress the lock button and rotate the change lever so

that the pointer points to the

symbol.

Then make sure that the bit is securely held in place by

turning it slightly. (Fig. 11)

Side grip (Fig. 12)

CAUTION:

• Always use the side grip to ensure operating safety

when drilling in concrete, masonry, etc.

• When the bit begins to break through concrete or if the

bit strikes reinforcing rods embedded in concrete, the

tool may react dangerously. Maintain good balance and

safe footing while holding the tool firmly with both

hands to prevent dangerous reaction.

The side grip swings around to either side, allowing easy

handling of the tool in any position. Loosen the side grip

by turning it counterclockwise, swing it to the desired

position and then tighten it by turning clockwise.

Switch action (Fig.13)

CAUTION:

Before plugging in the tool, always check to see that the

switch trigger actuates properly and returns to the “OFF”

position when released.

To start the tool, simply pull the trigger. Release the trig-

ger to stop.

Speed change (Fig. 14)

The revolutions and blows per minute can be adjusted

just by turning the adjusting dial. The dial is marked 1

(lowest speed) to 6 (full speed). Refer to the table below

for the relationship between the number settings on the

adjusting dial and the revolutions/blows per minute.

Hammer drilling operation (Fig. 15)

CAUTION:

When the bit begins to break through concrete or if the

bit strikes reinforcing rods embedded in concrete, the tool

may react dangerously. Maintain good balance and safe

footing while holding the tool firmly with both hands to

prevent dangerous reaction.

Set the change lever and the shift lever to the

symbol.

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

trigger. Do not force the tool. Light pressure gives best

results. Keep the tool in position and prevent it from slip-

ping 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 from the hole. By repeating this several

times, the hole will be cleaned out.
