OPERATION
CAUTION: Always insert the battery cartridge
all the way until it locks in place. If you can see
the red part on the upper side of the button, it is not
locked completely. Insert it fully until the red part can-
not 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.

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.
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.
Drilling operation
First, turn the adjusting ring so that the pointer 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.
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 small 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.
MAINTENANCE
CAUTION: Always be sure that the tool is
switched off and the battery cartridge is removed
before attempting to perform inspection or
maintenance.
NOTICE: Never use gasoline, benzine, thinner,
alcohol or the like. Discoloration, deformation or
cracks may result.
Replacing carbon brushes
►Fig.13: 1. Limit mark
Check the carbon brushes regularly.
Replace them when they wear down to the limit mark.
Keep the carbon brushes clean and free to slip in the
holders. Both carbon brushes should be replaced at the
same time. Use only identical carbon brushes.

Use a screwdriver to remove two screws then
remove the rear cover.

Raise the arm part of the spring and then place
it in the recessed part of the housing with a slotted bit
screwdriver of slender shaft or the like.

3.
Use pliers to remove the carbon brush caps of
the carbon brushes. Take out the worn carbon brushes,
insert the new ones and replace the carbon brush caps
in reverse.

Make sure to place the lead wire in opposite side
of the arm.
