To start the tool, simply pull the switch trigger. Tool speed 
is increased by increasing pressure on the switch trigger. 
Release the switch trigger to stop.

Lighting up the lamp (Fig. 4)

CAUTION:

• Do not look in the light or see the source of light 

directly.

Pull the switch trigger to light up the lamp. The lamp 
keeps on lighting while the switch trigger is being pulled.
The light automatically goes out 10 - 15 seconds after the 
switch trigger is released.

NOTE:

• Use a dry cloth to wipe the dirt off the lens of lamp. Be 

careful not to scratch the lens of lamp, or it may lower 
the illumination.

• Do not use thinner or gasoline to clean the lamp. Such 

solvents may damage it.

Reversing switch action (Fig. 5)

This tool has a reversing switch to change the direction of 
rotation. Depress the reversing switch lever from the A 
side for clockwise rotation or from the B side for 
counterclockwise rotation.
When the reversing switch lever is in the neutral position, 
the switch trigger cannot be pulled.

CAUTION:

• Always check the direction of rotation before operation.
• Use the reversing switch only after the tool comes to a 

complete stop. Changing the direction of rotation 
before the tool stops may damage the tool.

• When not operating the tool, always set the reversing 

switch lever to the neutral position.

Selecting the action mode

Rotation with hammering (Fig. 6)

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. 7)

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.

Hammering only (Fig. 8)

For chipping, scaling or demolition operations, depress 
the lock button and rotate the action mode changing knob 
to the   symbol. Use a bull point, cold chisel, scaling 
chisel, etc.

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. 9)

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. 10)

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

(Fig. 11)

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. 12)

Bit angle (when chipping, scaling or 
demolishing) (Fig. 13)

The bit can be secured at the desired angle. To change 
the bit angle, depress the lock button and rotate the action 
mode changing knob to the 

O

 symbol. Turn the bit to the 

desired angle.
Depress the lock button and rotate the action mode 
changing knob to the   symbol. Then make sure that the 
bit is securely held in place by turning it slightly. 

(Fig. 14)

Depth gauge (Fig. 15)

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. 16)

Use the dust cup to prevent dust from falling over the tool 
and on yourself when performing overhead drilling
