NOTE:
•
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
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.
First, slide the action mode change lever so that it
points to the
marking. The adjusting ring can be
aligned in any torque levels for this operation. 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 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.
MAINTENANCE
CAUTION:
•
Always be sure that the tool is switched off and
the battery cartridge is removed before attempt-
ing to perform inspection or maintenance.
•
Never use gasoline, benzine, thinner, alcohol
or the like. Discoloration, deformation or cracks
may result.
Replacing carbon brushes
► 1 . Limit mark
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.
► 1 . Rear cover 2. Screws
Raise the arm part of the spring and then place it in the
recessed part of the housing with a slotted bit screw-
driver of slender shaft or the like.
