operation

To change the speed, switch off the tool first. Push the 

speed change lever to display "2" for high speed or "1" 

for low speed. Be sure that the speed change lever is 

set to the correct position before operation.

If the tool speed is coming down extremely during the 

operation with display "2", push the lever to display "1" 

and restart the operation.

Selecting the action mode

CAUTION:

Always set the ring correctly to 

your desired mode mark. If you operate the tool 

with the ring positioned halfway between the 

mode marks, the tool may be damaged.

This tool has three action modes.

• 

 Drilling mode (rotation only)

• 

 Hammer drilling mode (rotation with 

hammering)

• 

 Screwdriving mode (rotation with clutch)

Select one mode suitable for your work. Turn the 

action mode changing ring and align the mark that you 

selected with the arrow on the tool body.

The fastening torque can be adjusted in 16 levels by 

turning the adjusting ring. Align the graduations with the 

arrow on the tool body. You can get the minimum fas

-

tening torque at 1 and maximum torque at 16.

Before actual operation, drive a trial screw into your mate-

rial or a piece of duplicate material to determine which 

torque level is required for a particular application.

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.

Installing or removing driver bit/drill bit

CAUTION:

 After inserting the driver bit, make 

sure that it is firmly secured. If it comes out, do not 

use it.

 Close

Turn the sleeve counterclockwise to open the chuck 

jaws. Place the driver bit/drill bit in the chuck as far 

as it will go. Turn the sleeve clockwise to tighten the 

chuck. To remove the driver bit/drill bit, turn the sleeve 

counterclockwise.

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 sud

-

den 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.
