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.
CAUTION:
Use the hanging/mounting parts for
their intended purposes only. Using for unintended
purpose may cause accident or personal injury.

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.
NOTICE:
When hanging the tool on your belt
using the hook, remove the bit and the side grip.
Installing driver bit holder
Optional accessory
► Fig.13: 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

Hold the tool firmly with one hand on the grip and the
other hand on the handle to control the twisting action.

NOTICE:
When the speed comes down extremely,
reduce the load or stop the tool to avoid the tool
damage.
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 adjusting ring so that the arrow on the tool
body points to the proper fastening torque level (1 - 21).
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 sudden
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 adjusting ring so that the arrow on the tool
body points to the
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.16: 1. Blow-out bulb
After drilling the hole, use the blow-out bulb to clean the
dust out of the hole.
Drilling operation
CAUTION:
Pressing excessively on the tool will
not speed up the drilling. In fact, this excessive pressure
will only serve to damage the tip of your drill bit, decrease
the tool performance and shorten the service life of the tool.
CAUTION:
Hold the tool firmly and exert care
when the drill bit begins to break through the
workpiece. There is a tremendous force exerted on
the tool/drill bit at the time of hole break through.
CAUTION:
A stuck drill bit can be removed
simply by setting the reversing switch to reverse
rotation in order to back out. However, the tool
may back out abruptly if you do not hold it firmly.
CAUTION:
Always secure workpieces in a
vise or similar hold-down device.
CAUTION:
If the tool is operated continuously until
the battery cartridge has discharged, allow the tool to rest
for 15 minutes before proceeding with a fresh battery.
First, turn the adjusting ring so that the arrow points to
the marking. Then proceed as follows.
Drilling in wood
When drilling in wood, the best results are obtained with
wood drills equipped with a guide screw. The guide screw
makes drilling easier by pulling the drill bit into the workpiece.
Drilling in metal
To prevent the drill bit from slipping when starting a
hole, make an indentation with a center-punch and
hammer at the point to be drilled. Place the point of the
drill bit in the indentation and start drilling.
Use a cutting lubricant when drilling metals. The excep-
tions are iron and brass which should be drilled dry.
