3.2 mm – 20 mm dia.
Optional accessories are subject to change without notice.
APPLICATIONS
䡬 By combined actions of ROTATION and IMPACT:
Boring holes in hard materials (concrete, marble,
granite, tiles, etc.)
䡬 By ROTATIONAL action:
Boring holes in metal, wood and plastic.
PRIOR TO OPERATION
1. Power source
Ensure that the power source to be utilized conforms
to the power requirements specified on the product
nameplate.
2. Power switch
Ensure that the power switch is in the OFF position.
If the plug is connected to a receptacle while the
power switch is in the ON position, the power tool
will start operating immediately, inviting serious
accident.
3. Extension cord
When the work area is removed from the power
source. Use an extension cord of sufficient thickness
and rated capacity. The extension cord should be
kept as short as practicable.
4. Mounting and dismounting of the bit.
For Drill chuck with chuck wrench (Fig. 1)
Fit the drill bit into the chuck and use the chuck
wrench to secure it, tightening the chuck by each
of the three holes in turn.
For keyless chuck (Fig. 2, 3)
(1) Mounting the bit
Turn the lock collar in the direction “AUF . RELEASE”
and open the chuck. After Inserting the drill bit Into
the chuck as far it will go, turn the lock collar in
the “GRIP . ZU” direction. Grip the retaining ring
and close the chuck by turning the sleeve clockwise
as viewed from the front.
(2) Dismounting the bit
Turn the lock collar in the direction “AUF . RELEASE”
to release the shucking force. Grip the retaining ring
and open the chuck by turning the sleeve
counterclockwise.
NOTE
When the sleeve does not become loose any further,
fix a regular spanner to spindle, hold regular spanner
firmly, then turn the sleeve to loosen by hand. (Fig.
4)
5. Selecting the appropriate drill bit
䡬 When boring concrete or stone
Use the drill bits specified in the Optional
Accessories.
䡬 When boring metal or plastic
Use an ordinary metalworking drill bit.
䡬 When boring wood
Use an ordinary woodworking drill bit.
However, when drilling 6.5 mm or smaller holes,
use a metalworking drill bit.
6. Confirm the direction of bit rotation (Fig. 5)
The bit rotates clockwise (viewed from the rear
side) by pushing the R-side of the reversing switch
lever. The L-side of the lever is pushed to turn the
bit counterclockwise.
CAUTION
䡬 Never change the direction of bit rotation during
operation.
Turn the power switch OFF before changing the
direction of bit rotation; otherwise, the motor will
burn.
䡬 Always use with clockwise rotation, when using it
as an impact drill.
7. Side handle attachment
Attach the side handle to the mounting part.
Rotate the side handle grip in a clockwise direction
to secure it.
Set the side handle to a position that is suited to
the operation and then securely tighten the side
handle grip.

8. IMPACT to ROTATION changeover (Fig. 6)
The impact drill can be switched from IMPACT
(impact plus rotation) to ROTATION (rotation only)
by simply sliding the change knob. When boring
concrete, stone, tile or similar board materials, slide
the change knob right. The drill head impacts against
the material while continuing to rotate.
When boring metal, wood or plastic, slide the change
knob fully to the left. The drill simply rotates as
an ordinary electric drill.
CAUTION
Do not use the impact drill in the IMPACT mode
if the material can be bored by rotation only. Such
action will not only reduce drill afficiency, but may
also damage the drill tip.
When changing over, ensure the change knob is
slide as far as it will go.
9. High-spped/Low-speed changeover
To change speed, rotate the gear shift lever as
indicated by the arrow in Fig. 7. The numeral “1”
engraved on the drill body denotes low speed, the
numeral “2” denotes high speed.
PRACTICAL HANDLING PROCEDURES
1. Speed adjustment and switch operation
䡬 The drill speed can be adjusted from 0 through full
speed by regulating the trigger-squeezing force.
The more the trigger is squeezed, the faster the drill
rotates. When the trigger is squeezed fully, the
speed is the maximum.
䡬 Pulling the trigger switch and pushing the stopper,
keeps the switched-on condition which is convenient
for continuous running. When switching off, the
stopper can be disconnected by pulling the trigger
again.
CAUTION
Drill at a maximum rotation speed when drilling
wooden materials.
2. When using as a Drill or an Impact Drill
(1) Pressing force of the drill
You cannot drill holes more quickly even if you
press the drill with a stronger force than necessary.
It not only damages tip of drill bit and decreases
the efficiency of operation, but also shortens the
life of the drill tip.
(2) In case of penetrating holes
Drill bits can be broken when the material being
drilled is penetrated. It is important to decrease
pressing force just before penetrating.
CAUTION
In continuous operation, conduct no-load operation
for five seconds after completing a drilling job.
(3) When a thick drill bit is used
Your arm is subjected to larger reaction force when
a thicker drill bit is used. Be careful not to be moved
by the reaction force. For this, establish a foothold,
hold the unit tightly with both hands perpendicularly
to the material being drilled.
3. Using a large diameter drill bit
The larger the drill bit diameter, the larger the
reactive force on your arm. Be careful not to lose
control of the drill because of this reactive force.
To maintain firm control, establish a good foothold,
hold the drill tightly with both hands, and ensure
that the drill is vertical to the material being drilled.
4. When drilling completely through the material
When the drill bit bores completely through the
material, careless handling often results in a broken,
drill bit or damage to the drill body itself due to
the sudden movement of the drill. Always be alert
and ready to release pushing force when drilling
through the material.
MAINTENANCE AND INSPECTION
1. Inspecting the drill bit
Continued use of a worn and/or damaged drill bit
will result in reduced drilling efficiency and may
seriously overload the drill motor. Inspect the drill
bit frequently and replace it as necessary.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure
that they are properly tightened. Should any of the
screws be loose, retighten them immediately. Failure
to do so could result in serious hazard.
3. Maintenance of the motor
The motor unit winding is the very “heart” of the
power tool. Exercise due care to ensure the winding
does not become damaged and/or wet with oil or
water.
4. Servicing
Consult an authorized Service Center in the event
of power tool failure.
