WARNING
WEAR RESPIRAT ORY PROTECTION
Some dust created by power sanding, sawing, grinding, drilling and other construction
activities contain chemicals known to the State of California to cause cancer, birth
defects or other reproductive harm. Some examples of these chemicals are:
• Lead from lead-base paints,
• Crystalline Silica from bricks, cement and other masonry products, and
• Arsenic and Chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work.
To reduce your exposure to these chemicals, work in a well ventilated area and work
with approved safety equipment, such as those dust masks that are specially designed
to filter out microscopic particles.

Operation
APPLICATIONS:
By combined actions of ROTATION and IMPACT: Boring holes in hard surfaces
(concrete, marble, granite, tiles, etc.)
By ROTATIONAL action: Boring holes in metal, wood and plastic.
PRE-OPERATION:
1. Power source:
Ensure that the power source to be utilized conforms to the power source require
ments specified on the product nameplate.
2. Power switch:
Ensure that the switch is in the OFF position. If the plug is connected to a
receptacle while the switch is in the ON position, the power tool will start operating
immediately and can cause serious injury.
3. Extension cord:
When the work area is far away from the power source, use an extension cord of
sufficient thickness and rated capacity. The extension cord should be kept as short
as practicable.
WARNING: DAMAGED CORD MUST BE REPLACED OR REPAIRED.
4. Check the receptacle
If the receptacle only loosely accepts the plug, the receptacle must be repaired.
Contact a licensed electrician to make appropriate repairs.
If such a faulty receptacle is used, it may cause overheating, resulting in a serious
hazard.
5. Confirming condition of the environment:
Confirm that the work site is placed under appropriate conditions conforming to
prescribed precautions.
6. Selecting the appropriate drill bit:
a. When boring concrete or stone, use a masonry drill bit.
b. When boring metal or plastic, use an ordinary metalworking drill bit.
c. When boring wood, u se an ordinary woodworking drill bit. However, when
drilling 1/4" (6.5 mm) or smaller holes, use a metalworking drill bit.
7. Mounting and dismounting of the bit. (Fig. 2)
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.
(Fig. 2)

Operation
PRE-OPERATION (CONTINUED):
8. Fixing the side handle (Fig. 3):
Loosen the knob bolt on the side handle, and
attach the side handle to the gear cover in a
position convenient for drilling. Match the
projecting part of the handle to the groove on
the gear cover, and firmly tighten the knob bolt.
To remove the side handle, loosen the knob
bolt and rotate the handle.
To attach a depth gauge on the side handle,
insert the gauge into the U-shaped groove on
the side handle, adjust the position of the depth
gauge in accordance with the desired depth of
the hole, and firmly tighten the wing bolt.
9. IMPACT to ROTATION change over (Fig. 4):
The Hammer Drill can be switched from
IMPACT (impact plus rotation) to ROTATION
(rotation only) by rotating the change lever
(Fig. 1). When boring concrete, stone, tile or
similar hard materials, rotating the change lever
to IMPACT side. The drill head impacts against
the material while continuing to rotate.
When boring metal, wood or plastic, rotating
the change lever to ROTATION side. The drill
rotates as an ordinary electric drill.
CAUTION: DO NOT USE THE HAMMER
DRILL IN THE IMPACT
FUNCTION IF THE
MATERIAL CAN BE BORED
BY ROTATION ONLY. SUCH
ACTION WILL NOT ONLY
REDUCE DRILL EFFICIENCY,
BUT MAY ALSO DAMAGE THE
DRILL TIP.
NOTE: The change lever may not rotate smoothly
when changing from hammer drill mode to
drill mode (Fig. 4).
In this case, switch ON and operate the
machine for few seconds. The spindle
shaft will then be pushed forward, and the
change lever can be moved smoothly.

OPERATION:
Operation
CAUTION: TO PREVENT ACCIDENTS, MAKE SURE TO TURN THE SWITCH
1. Operation of switch:
a. The drill speed can be adjusted from O 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.
b. Pulling the trigger and pushing the stopper, it keeps the switched-on condition
which is convenient for continuous running. When switching off, the stopper
can be disconnected by pulling the trigger again.
2. When using as a Drill or a Hammer Drill:
a. 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 bits and decreases the
efficiency of operation, but also shortens the life of the drill.
b. 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
c. 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.
OFF AND DISCONNECT THE PLUG FROM THE RECEPTACLE
WHEN THE DRILL BITS AND OTHER VARIOUS PARTS ARE
INSTALLED OR REMOVED. THE POWER SWITCH SHOULD
ALSO BE TURNED OFF DURING A WORK BREAK AND AFTER
WORK.
OPERATION FOR FIVE SECONDS AFTER COMPLETING A
DRILLING JOB.
