CAUTION:
Always check the direction of
rotation before operation.
CAUTION:
Use the reversing switch only after
the tool comes to a complete stop. Changing the
direction of rotation before the tool stops may dam-
age the tool.
CAUTION:
When not operating the tool,
always set the reversing switch lever to the neu-
tral position.
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 coun-
terclockwise rotation.
When the reversing switch lever is in the neutral posi-
tion, the switch trigger cannot be pulled.
Selecting the action mode
NOTICE:
Do not rotate the action mode chang-
ing knob when the tool is running. The tool will be
damaged.
NOTICE:
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 action mode positions.
Rotation with hammering
For drilling in concrete, masonry, etc., rotate the action
mode changing knob to the
bide-tipped drill bit.
► Fig.6: 1. Action mode changing knob
Rotation only
For drilling in wood, metal or plastic materials, rotate
the action mode changing knob to the symbol. Use a
twist drill bit or wood drill bit.

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)
CAUTION:
Always use the side grip to ensure
safe operation.
CAUTION:
After installing or adjusting the
side grip, make sure that the side grip is firmly
secured.
Install the side grip so that the grooves on the grip fit in
the protrusions on the tool barrel. Turn the grip clock-
wise to secure it. The grip can be fixed at desired angle.

Grease
Coat the shank end of the drill bit beforehand with a
small amount of grease (about 0.5 - 1 g).
This chuck lubrication assures smooth action and lon-
ger service life.
Installing or removing drill bit
Clean the shank end of the drill bit and apply grease
before installing the drill bit.
► Fig.9: 1. Shank end 2. Grease
Insert the drill bit into the tool. Turn the drill bit and push
it in until it engages.
After installing the drill bit, always make sure that the
drill bit is securely held in place by trying to pull it out.
► Fig.10: 1. Drill bit
To remove the drill bit, pull the chuck cover down all the
way and pull the drill bit out.

Depth gauge
The depth gauge is convenient for drilling holes of uniform
depth. Loosen the side grip and insert the depth gauge
into the hole on the side grip. Adjust the depth gauge to
the desired depth and tighten the side grip firmly.
► Fig.12: 1. Hole 2. Depth gauge
NOTE: Make sure that the depth gauge does not
touch the main body of the tool when attaching it.
Dust cup (optional accessory)
Use the dust cup to prevent dust from falling over the
tool and on yourself when performing overhead drilling
operations. Attach the dust cup to the bit as shown in
the figure. The size of bits which the dust cup can be
attached to is as follows.

Dust cup set (optional accessory)
NOTICE:
Do not use the dust cup set when drill-
ing in metal or similar. It may damage the dust cup
set due to the heat produced by small metal dust or
similar. Do not install or remove the dust cup set with
the drill bit installed in the tool. It may damage the
dust cup set and cause dust leak.
NOTE: The standard side grip cannot be used
with the dust cup set being installed on the tool.
Use an optional side grip when the dust cup set is
installed on the tool.
Before installing the dust cup set, remove the bit from
the tool if installed.
Install the spacer so that the grooves on the spacer fit in
the protrusions on the tool barrel while widening it. Be
careful for the spring not to come off from the slit of spacer.
