CAUTION:
Do not turn the adjusting dial when
the tool is running. Failure to do so may result in
the loss of control of the tool and cause an injury.
NOTICE:
The speed adjusting dial can be turned
only as far as 5 and back to 1. Do not force it past
5 or 1, or the speed adjusting function may no
longer work.
NOTE: Soft no-load rotation function
Blows at no load per minute becomes smaller than
those on load in order to reduce vibration under no
load, but this does not show trouble.
Once operation starts with a bit against concrete,
blows per minute increase and reach the numbers as
shown in the table.
When temperature is low, the tool may not have this
function even with the motor rotating.
Lighting up the front lamp
► Fig.5: 1. Lamp
CAUTION:
Do not look in the light or see the

Pull the switch trigger to light up the lamp. The lamp
keeps on lighting while the switch trigger is being pulled.
The lamp goes out approximately 10 seconds after
releasing the switch trigger.
NOTE: Use a dry cloth to wipe the dirt off the lens of
the lamp. Be careful not to scratch the lens of lamp, or
it may lower the illumination.
Electronic function
The tool is equipped with the electronic functions for
easy operation.
• Constant speed control
The speed control function provides the constant
rotation speed regardless of load conditions.
• Soft start
The soft-start function minimizes start-up shock,
and makes the machine start smoothly.

Side handle (auxiliary handle)
CAUTION:
Always use the side handle to
ensure safe operation.
CAUTION:
After installing or adjusting the
side handle, make sure that the side handle is
firmly secured.
The side handle can be swung in a vertical direction
and secured at any desired position. It can also be
adjusted at eight steps back and forth in a horizontal
direction. Loosen the clamp nut to swing the side han-
dle to a desired position, and then tighten the clamp nut
securely.

Installing or removing bit
Grease
Clean the shank end of the bit and apply grease before
installing the bit.
Coat the shank end of the bit beforehand with a small
amount of grease (about 0.5 - 1 g). This chuck lubrica-
tion assures smooth action and longer service life.
► Fig.7: 1. Shank end 2. Grease
Insert the bit into the tool. Turn the bit and push it in until
it engages.
If the bit cannot be pushed in, remove the bit. Pull the
release cover down a couple of times. Then insert the
bit again. Turn the bit and push it in until it engages.
After installing the bit, always make sure that the bit is
securely held in place by trying to pull it out.
► Fig.8: 1. Bit 2. Release cover
To remove the bit, pull the release cover down all the
way and pull the bit out.
► Fig.9: 1. Bit 2. Release cover
Bit angle
The bit can be secured at 12 different angles. To
change the bit angle, slide the change ring cover for-
ward, then turn the change ring cover to change the bit
angle. At the desired angle, slide the change ring cover
back to the original position. The bit will be secured in
place.
After changing the bit angle, make sure the angle is
fixed by trying to rotate the bit.
