► 1 . Driver bit holder 2. 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 (1-3/4") 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.
NOTICE:
Do not cover vents, or it may cause over-
heating and damage to the tool.

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
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
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.
