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 bit, decrease the tool
performance and shorten the service life of the tool.
• There is a tremendous force exerted on the tool/bit at
the time of hole break through. Hold the tool firmly and
exert care when the bit begins to break through the
workpiece.
• A stuck 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.
• Always secure small workpieces in a vise or with a
similar hold-down device.
• 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.
• Do not pull the switch trigger repeatedly when the
motor is locked. It may damage the tool.
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 bit into the workpiece.
Drilling in metal
To prevent the bit from slipping when starting to make a
hole, make an indentation with a center-punch and
hammer at the point to be drilled. Place the point of the bit
in the indentation and start drilling.
Use a cutting lubricant when drilling metals. The
exceptions are iron and brass which should be drilled dry.
Screwdriving operation
First, turn the action mode changing ring so that the arrow
on the tool body points to the
adjusting ring to the proper torque level for your work.
Then proceed as follows.
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.
CAUTION:
• Make sure that the driver bit is inserted straight in the
screw head, or the screw and/or bit may be damaged.
NOTE:
• When driving wood screw, predrill a pilot hole 2/3 the
diameter of the screw. It makes driving easier and
prevents splitting of the workpiece.
Using the tool as a hand screwdriver
(Fig. 11)
Switch off the tool.
Move the reversing switch lever to the neutral position.
Turn the tool.
NOTE:
• This use is convenient for checking the screwdriving.
• Do not use the tool for work requiring excessive force,
such as tightening bolt or removing rusted screws.
marking. Adjust the
Using holster (Optional accessory)
CAUTION:
• Do not use for tools such as a drill with a bit installed on
them.
• Turn off the tool and wait until it comes to a complete
stop before placing it in the holster.
Be sure to close the holster securely so that it holds the
tool firmly. (Fig. 12)
Thread a waist belt or similar through holster holder.

Put the tool in the holster and lock it with the holster
button. (Fig. 14)
You can keep two bits at the front of holster.

• Always be sure that the tool is switched off and the
battery cartridge is removed before performing any
inspection or maintenance.
