Installing the bit holder (Optional accessory) 

Fig.11 

Fit the 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 bit holders. 
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 part on the 
upper side of the button, it is not locked completely. 
Insert it fully until the red part cannot be seen. If not, 
it may accidentally fall out of the tool, causing injury 
to you or someone around you. 

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. 

CAUTION: 

• 

Do not cover vents, or it may cause overheating 
and damage to the tool.

Hammer drilling operation 

CAUTION: 

• 

There is a tremendous and sudden twisting force 
exerted on the tool/bit at the time of hole 
break-through, 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 bit. 
Position the 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 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) 

Fig.13 

After drilling the hole, use the blow-out bulb to clean the 
dust out of the hole. 

Screwdriving operation 

Fig.14 

First, turn the action mode changing ring so that the 
arrow on the tool body points to the

 marking. Adjust 

the adjusting ring to the proper torque level for your work. 
Then proceed as follows. 
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. 

CAUTION: 

• 

Make sure that the driver bit is inserted straight in 
the screw head, or the screw and/or bit may be 
damaged. 

NOTE: 

• 

When driving wood screw, predrill a pilot hole 2/3 
the diameter of the screw. It makes driving easier 
and prevents splitting of the workpiece. 

Drilling operation 

First, turn the adjusting ring so that the pointer points to 
the 

  marking. Then proceed as follows. 

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 bit, decrease the 
tool performance and shorten the service life of the 
tool. 

• 

There is a tremendous force exerted on the tool/bit 
at the time of hole break through. Hold the tool 
firmly and exert care when the bit begins to break 
through the workpiece. 

• 

A stuck 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. 

• 

Always secure small workpieces in a vise or with a 
similar hold-down device. 

• 

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. 

• 

Do not pull the switch trigger repeatedly when the 
motor is locked. It may damage the tool. 

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 bit into the 
workpiece. 

Drilling in metal 

To prevent the bit from slipping when starting to make a 
hole, make an indentation with a center-punch and 
hammer at the point to be drilled. Place the point of the 
bit in the indentation and start drilling. 
Use a cutting lubricant when drilling metals. The 
exceptions are iron and brass which should be drilled dry.
