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 the driver bit or drill bit
Fig.10
Turn the sleeve counterclockwise to open the chuck
jaws. Place the bit in the chuck as far as it will go. Turn
the sleeve clockwise to tighten the chuck.
To remove the bit, turn the sleeve counterclockwise.
Installing the hook
Fig.11
The hook is convenient for temporarily hanging the tool.
This can be installed on either side of the tool.
To install the hook, insert it into a groove in the tool
housing on either side and then secure it with a screw.
To remove, loosen the screw and then take it out.
Installing the bit holder (Optional accessory)
Fig.12
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.

Adjusting the fastening torque

Fig.9
The fastening torque can be adjusted in 16 steps by
turning the adjusting ring. Align the graduations with the
arrow on the tool body. You can get the minimum
fastening torque at 1 and maximum torque at 16.
Before actual operation, drive a trial screw into your
material or a piece of duplicate material to determine
which torque level is required for a particular application.
The following shows the rough guide of the relationship
between the screw size and graduation.

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.
When the speed comes down extremely, reduce
•
the load or stop the tool to avoid the tool damage.
Fig.13
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.
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
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.
