Tips for maintaining maximum battery life
1. Charge the battery cartridge before completely dis-
charged.
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 charg-
ing it.
4. Charge the Nickel Metal Hydride battery cartridge
when you do not use it for more than six months.
Refer to the table below for the charging time.
Switch action (Fig. 3)
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 switch trigger. Tool speed
is increased by increasing pressure on the switch trigger.
Release the switch trigger to stop.
Reversing switch action (Fig. 4)
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 reversing switch lever is in the neutral position,
the switch trigger cannot be pulled.
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.
Speed change (Fig. 5)
To change the speed, first switch off the tool and then
slide the speed change lever to the "2" side for high
speed or "1" 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 halfway between the "1" side and "2"
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 action mode (Fig. 6)
This tool has an mode change lever. For drilling, depress
the lock button and then slide the action mode change
lever to the left (
f symbol). For screwing, slide the
action mode change lever to the right (
U symbol) until
it is locked. If it is hard to turn the lever, first turn the
chuck slightly in either direction and then turn the lever
again.
CAUTION:
• Always slide the action mode change lever all the way
to your desired mode position. If you operate the tool
with the
lever positioned halfway between the mode
symbols, the tool may be damaged.
• Do not use the action mode change lever while the tool
is running. The tool may be damaged.
Adjusting the fastening torque (Fig. 7)
The fastening torque can be adjusted in 16 steps by turn-
ing the adjusting ring so that its graduations are aligned
with the pointer on the tool body.
FIrst, slide the action mode change lever to the position
of
U symbol.
The fastening torque is minimum when the number 1 is
aligned with the pointer, and maximum when the marking
is aligned with the pointer. The clutch will slip at various
torque levels when set at the number 1 to 16. 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.
CAUTION:
• The adjusting ring does not lock when the pointer is
positioned only halfway between the graduations.
