tive material.
(2) Avoid storing battery cartridge in a container
with other metal objects such as nails, coins,
etc.
(3) Do not expose battery cartridge to water or
rain.
A battery short can cause a large current flow,
overheating, possible burns and even a break-
down.
7. Do not store the tool and battery cartridge in
locations where the temperature may reach or
exceed 50°C (122°F).
8. Do not incinerate the battery cartridge even if it
is severely damaged or is completely worn out.
The battery cartridge can explode in a fire.

Tips for maintaining maximum battery life
1. Charge the battery cartridge before completely
discharged.
Always stop tool operation and charge the bat-
tery 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 tempera-
ture at 10°C – 40°C (50°F – 104°F). Let a hot bat-
tery cartridge cool down before charging it.
4. Charge the Nickel Metal Hydride battery car-
tridge when you do not use it for more than six
months.

FUNCTIONAL DESCRIPTION

CAUTION:
• Always be sure that the tool is switched off and the bat-
tery cartridge is removed before adjusting or checking
function on the tool.
Installing or removing battery cartridge (Fig. 1)
• Always switch off the tool before insertion or removal of
the battery cartridge.
• To remove the battery cartridge, withdraw it from the
tool while pressing the buttons on both sides of the car-
tridge.
• To insert the battery cartridge, align the tongue on the
battery cartridge with the groove in the housing and slip
it into place. Always insert it all the way until it locks in
place with a little click. If not, it may accidentally fall out
of the tool, causing injury to you or someone around
you.
• Do not use force when inserting the battery cartridge. If
the cartridge does not slide in easily, it is not being
inserted correctly.
Switch action (Fig. 2)
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. 3)
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 coun-
terclockwise 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. 4)
This tool has a three-gear speed change lever. To
change the speed, first switch off the tool and then slide
the speed change lever to the "1" position for low speed,
"2" position for medium speed or "3" position for high
speed. Be sure that the speed change lever is set to the
correct position before operation. Use the right speed for
your job.
NOTE:
When changing the position from "1" to "3" or from "3" to
"1", it may be a little difficult to slide the speed change
lever. At this time, switch on and run the tool for a second
at the "2" position, then stop the tool and slide to your
desired position.
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" position, "2"
position and "3" position, 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 lever. Select
one of the three modes suitable for your work needs by
using this lever.
For rotation only, slide the lever so that it points toward
the m mark on the tool body.
For rotation with hammering, slide the lever so that it
points toward the mark on the tool body.
For rotation with clutch, slide the lever so that it points
toward the mark on the tool body.
NOTE:
When changing the position from
tle difficult to slide the mode change lever. At this time,
switch on and run the tool for a second at the
then stop the tool and slide to your desired position.
CAUTION:
Always set the lever correctly to your desired mode mark.
If you operate the tool with the lever positioned halfway
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 the number 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.
