• If you charge a battery cartridge from a just-operated tool or a battery cartridge which has been left in a location
exposed to direct sunlight or heat for a long time, the charging light may flash in red color. If this occurs, wait for a
while. Charging will begin after the battery cartridge cools. The battery cartridge will cool faster if you remove the
battery cartridge from the battery charger.
• If the charging light flashes alternately in green and red color, a problem exists and charging is not possible. The ter-
minals on the charger or battery cartridge are clogged with dust or the battery cartridge is worn out or damaged.
Trickle charge (Maintenance charge)
If you leave the battery cartridge in the charger to prevent spontaneous discharging after full charge, the charger will
switch into its “trickle charge (maintenance charge)” mode and keep the battery cartridge fresh and fully charged.
Tips for maintaining maximum battery life
1. Charge the battery cartridge before completely discharged.
Always stop tool operation and charge the battery cartridge when you notice less tool power.
2. Never recharge a fully charged battery cartridge.
Overcharging shortens the battery service life.
3. Charge the battery cartridge with room temperature at 10°C – 40°C (50°F – 104°F).
Let a hot battery cartridge cool down before charging it.
4. Charge the Nickel Metal Hydride battery cartridge when you do not use it for more than six months.
Installing or removing driver bit or drill bit
(Fig. 3 & 4)
Important:
Always be sure that the tool is switched off and the bat-
tery cartridge is removed before installing or removing
the bit.
Hold the ring and turn the sleeve counterclockwise to
open the chuck jaws. Place the bit in the chuck as far as it
will go. Hold the ring firmly and turn the sleeve clockwise
to tighten the chuck.
To remove the bit, hold the ring and turn the sleeve coun-
terclockwise. When not using the driver bit, keep it in the
bit holders. Bits 45 mm long can be kept there.
Switch action (Fig. 5)
CAUTION:
Before inserting the battery cartridge into the tool, always
check to see that the switch trigger actuates properly and
returns to the “OFF” position when released.
To start the tool, simply pull the trigger. Tool speed is
increased by increasing pressure on the trigger. Release
the trigger to stop.
Reversing switch action (Fig. 6)
CAUTION:
• Always check the direction of rotation before operation.
• Use the reversing switch only after the tool comes to a
complete stop. Changing the direction of rotation
before the tool stops may damage the tool.
• When not operating the tool, always set the reversing
switch lever to the neutral position.
This tool has a reversing switch to change the direction of
rotation. Depress the reversing switch lever from the A
side for clockwise rotation or from the B side for counter-
clockwise rotation. When the switch lever is in the neutral
position, the switch trigger cannot be pulled.
Speed change (Fig. 7)
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.
Adjusting the fastening torque (Fig. 8)
The fastening torque can be adjusted in 17 steps by turn-
ing the adjusting ring so that its graduations are aligned
with the pointer on the tool body. The fastening torque is
minimum when the number 1 is aligned with the pointer,
and maximum when the
m
marking is aligned with the
pointer.
The clutch will slip at various torque levels when set at
the number 1 to 16. The clutch is designed not to slip at
the
m marking.
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.
NOTE:
• The adjusting ring does not lock when the pointer is
positioned only half-way between the graduations.
• Do not operate the tool with the adjusting ring set
between the number 16 and the
m marking. The tool
may be damaged.
