ASSEMBLY
Screwdriving operation
CAUTION: Adjust the adjusting ring to the
proper torque level for your work.
CAUTION: Always be sure that the tool is
switched off and the battery cartridge is removed
before carrying out any work on the tool.
CAUTION: Make sure that the driver bit is
inserted straight in the screw head, or the screw
and/or driver bit may be damaged.
Installing or removing driver bit/
drill bit
Optional accessory
► Fig.10: 1. Sleeve 2. Close 3. Open
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.
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.
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.
Installing hook
► Fig.11: 1. Groove 2. Hook 3. Screw
Hammer drilling operation
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.
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.
Installing driver bit holder
Optional accessory
► Fig.12: 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 can be kept there.
OPERATION
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.
Blow-out bulb
Optional accessory
► Fig.14: 1. Blow-out bulb
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.
After drilling the hole, use the blow-out bulb to clean the
dust out of the hole.
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.
