OPERATION
CAUTION:
Always insert the battery cartridge all
the way until it locks in place. 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.
CAUTION:
Do not cover vents, or it may
cause overheating and damage to the tool.
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.
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 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 action mode changing ring so that the arrow
on the tool body points to the
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.

First, turn the adjusting ring so that the arrow points to

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.
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.
CAUTION:
Do not pull the switch trigger
repeatedly when the motor is locked. It may dam-
age the tool.
Using the tool as a hand screwdriver
► Fig.11
Switch off the tool.
Move the reversing switch lever to the neutral position.
Turn the action mode changing ring so that the arrow
points to the
marking.
Turn the tool.
NOTE: This use is convenient for checking the
screwdriving.
NOTE: Do not use the tool for work requiring exces-
sive force, such as tightening bolt or removing rusted
screws.
