Installing driver bit holder

Optional accessory

 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.

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 pres-

sure 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

Optional accessory

 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 to cool the workpiece when 

drilling metals. The exceptions 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.

Using the tool as a hand screwdriver

► 

Fig.14

Switch off the tool. 

Move the reversing switch lever to the neutral position. 

Turn the action mode changing ring so that the arrow 

points to the 

 marking. 

Turn the tool.

NOTE:

 This use is convenient for checking the 

screwdriving.

NOTE:

 Do not use the tool for work requiring exces-

sive force, such as tightening bolt or removing rusted 

screws.
