Screwdriving operation
011499
First, turn the action mode changing ring so that the
arrow on the tool body points to the
marking. Adjust
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 screws, predrill pilot holes to
make driving easier and to prevent splitting of the
workpiece. See the chart.

Drilling operation
First, turn the adjusting ring so that the pointer points to
the
marking. Then proceed as follows.
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.
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.
MAINTENANCE
CAUTION:
•
Always be sure that the tool is switched off and the
battery cartridge is removed before attempting to
perform inspection or maintenance.
•
Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may
result.
Replacing the carbon brushes
1
006258
Replace 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.
