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.

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
► Fig.9: 1. Sleeve
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.

Installing hook

CAUTION:
When installing the hook, always
secure it with the screw firmly. If not, the hook may
come off from the tool and result in the personal injury.
► Fig.10: 1. Groove 2. Hook 3. Screw
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 driver bit holder
Optional accessory
► Fig.11: 1. Driver bit holder 2. Driver bit
Fit the driver bit holder into the protrusion at the tool foot

To change the speed, switch off the tool first. Select
the "2" side for high speed or "1" for low speed but high
torque. 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 "2", slide the lever to the "1" and restart
the operation.

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.
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.
