Driver bit
Fit the driver bit holder into the protrusion at the tool foot
on either right or left side and secure it with a screw.
When not using the driver bit, keep it in the driver bit
holders. Driver bits 45 mm-long can be kept there.

Grip
Insert the side grip so that the protrusions on the arm
fit in the recesses on the tool. Then tighten the grip by
turning clockwise.
Depending the operations, you can install the side grip
either right or left side of the tool.
OPERATION
CAUTION:
Always insert the battery cartridge
all the way until it locks in place.
If you can see the
red indicator on the upper side of the button, it is not
locked completely. Insert it fully until the red indicator
cannot be seen. If not, it may accidentally fall out of
the tool, causing injury to you or someone around
you.
CAUTION:
When the speed comes down
extremely, reduce the load or stop the tool to
avoid the tool damage.
Hold the tool firmly with one hand on the grip and the
other hand on the bottom of the battery cartridge to
control the twisting action.
Screwdriving operation
CAUTION:
Adjust the adjusting ring to the
proper torque level for your work.
CAUTION:
Make sure that the driver bit is
inserted straight in the screw head, or the screw
and/or driver bit may be damaged.
First, turn the action mode changing ring so that the
arrow on the tool body points to the
marking.
Place the point of the driver bit in the screw head and
apply pressure to the tool. Start the tool slowly and then
increase the speed gradually. Release the switch trigger
as soon as the clutch cuts in.

NOTE:
When driving wood screw, pre-drill a pilot hole
2/3 the diameter of the screw. It makes driving easier
and prevents splitting of the workpiece.
Hammer drilling operation
CAUTION:
There is a tremendous and sudden
twisting force exerted on the tool/drill bit at the
time of hole breakthrough, when the hole becomes
clogged with chips and particles, or when striking
reinforcing rods embedded in the concrete.
First, turn the action mode changing ring so that the arrow
on the tool body points to the
marking. The adjusting
ring can be aligned in any torque levels for this operation.
Be sure to use a tungsten-carbide tipped drill bit.
Position the drill bit at the desired location for the hole,
then pull the switch trigger. Do not force the tool. Light
pressure gives best results. Keep the tool in position
and prevent it from slipping away from the hole.
Do not apply more pressure when the hole becomes clogged with
chips or particles. Instead, run the tool at an idle, then remove the
drill bit partially from the hole. By repeating this several times, the
hole will be cleaned out and normal drilling may be resumed.
Blow-out bulb

Blow-out bulb
After drilling the hole, use the blow-out bulb to clean the
dust out of the hole.
Drilling operation
First, turn the action mode changing ring so that the arrow
points to the
marking. Then proceed as follows.
Drilling in wood
When drilling in wood, the best results are obtained with
wood drills equipped with a guide screw. The guide screw
makes drilling easier by pulling the drill bit into the workpiece.
Drilling in metal
To prevent the drill bit from slipping when starting a hole, make an
indentation with a center-punch and hammer at the point to be drilled.
Place the point of the drill bit in the indentation and start drilling.
Use a cutting lubricant when drilling metals. The excep-
tions are iron and brass which should be drilled dry.
CAUTION:
Pressing excessively on the tool will
not speed up the drilling.
In fact, this excessive pressure
will only serve to damage the tip of your drill bit, decrease
the tool performance and shorten the service life of the tool.
CAUTION:
Hold the tool firmly and exert care
when the drill bit begins to break through the
workpiece.
There is a tremendous force exerted on
the tool/drill bit at the time of hole break through.
CAUTION:
A stuck drill bit can be removed
simply by setting the reversing switch to reverse
rotation in order to back out. However, the tool
may back out abruptly if you do not hold it firmly.
CAUTION:
Always secure workpieces in a
vise or similar hold-down device.
CAUTION:
If the tool is operated continuously until
the battery cartridge has discharged, allow the tool to rest
for 15 minutes before proceeding with a fresh battery.
