Speed change (Fig. 4)
To change the speed, first switch off the tool and then
slide the speed change lever to the “ II ” side for high
speed or “ I ” side for low speed. Be sure that the speed
change lever is set to the correct position before opera-
tion. Use the right speed for your job.
CAUTION:
• Always set the speed change lever fully to the correct
position. If you operate the tool with the speed change
lever positioned half-way between the “ I ” side and “ II ”
side, the tool may be damaged.
• Do not use the speed change lever while the tool is run-
ning. The tool may be damaged.
Selecting the action mode (Fig. 5)
This tool employs an action mode changing ring. Select
one of the three modes suitable for your work needs by
using this ring. For rotation only, turn the ring so that the
arrow on the tool body points toward the M mark on the
ring. For rotation with hammering, turn the ring so that
the arrow points toward the X on the ring. For rotation
with clutch, turn the ring so that the arrow points toward
the U mark on the ring.
CAUTION:
Always set the ring correctly to your desired mode mark.
If you operate the tool with the ring positioned half-way
between the mode marks, the tool may be damaged.
Adjusting the fastening torque (Fig. 6)
The fastening torque can be adjusted in 16 steps by turn-
ing the adjusting ring so that its graduations are aligned
with the arrow on the tool body. The fastening torque is
minimum when the number 1 is aligned with the arrow,
and maximum when thenumber 16 is aligned with the
arrow.
Before actual operation, drive a trial screw into your
material or a piece of duplicate material to determine
which torque level is required for a particular application.
Installing or removing driver bit or drill bit
(Fig.7 & 8)
Important:
Always be sure that the tool is switched off and the bat-
tery cartridge is removed before installing or removing
the bit.
Turn the sleeve counterclockwise to open the chuck jaws.
Place the bit in the chuck as far as it will go. Turn the
sleeve clockwise to tighten the chuck. To remove the bit,
turn the sleeve counterclockwise.
When not using the driver bit, keep it in the bit holders.
Bits 45 mm long can be kept there.
Side grip (auxiliary handle) (Fig. 9)
Always use the side grip to ensure operating safety.
Install the side grip so that the teeth on the grip fit in
between the protrusions on the tool barrel. Then tighten
the grip by turning clockwise at the desired position. It
may be swung 360° so as to be secured at any position.
Adjustable depth rod (Fig. 10)
The adjustable depth rod is used to drill holes of uniform
depth. Loosen the thumb screw, set to desired position,
then tighten the thumb screw.
