Installing bit holder

Fit the bit holder into the protrusion at the tool foot on
eithher right or left side and secure it with a screw.
When not using the driver bit, keep it in the bit holders.
Bits 45 mm (1-3/4”) long can be kept there.

Hook

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 hous-
ing on either side and then secure it with a screw. To
remove, loosen the screw and then take it out.
OPERATION

Screwdriving operation

First, slide the action mode change lever to the position
of symbol and select the fastening torque.
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:
•Make sure that the driver bit is inserted straight in
the screw head, or the screw and/or bit may be
damaged.
•When driving wood screws, predrill pilot holes to
make driving easier and to prevent splitting of the
workpiece. See the chart.
•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.

Drilling operation

First, slide the action mode change lever to the position
of symbol.
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 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 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 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 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.
