(1) Do not touch the terminals with any
conductive 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
breakdown.
6.
Do not store the tool and battery cartridge in
locations where the temperature may reach or
exceed 50 °C (122 °F).
7.
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.
8.
Be careful not to drop or strike battery.
9.
Do not use dropped or struck battery.

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.
FUNCTIONAL DESCRIPTION
CAUTION:
• Always be sure that the tool is switched off and the
battery 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 sliding the button on the front of the cartridge.
• 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 you can see the red part on
the upper side of the button, it is not locked completely.
Insert it fully until the red part cannot be seen. 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
counterclockwise 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)
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 operation. 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
running. The tool may be damaged.
Adjusting the fastening torque (Fig. 5)
The fastening torque can be adjusted in 17 steps by
turning 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
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
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.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and the
battery cartridge is removed before carrying out any
work on the tool.
