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 dis-
charged.
Always stop tool operation and charge the battery car-
tridge 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 by inserting it into the
charger.
4. Charge the Nickel Metal Hydride battery cartridge when
you do not use it for more than six months.
Selecting correct socket
Always use the correct size socket for bolts and nuts. An
incorrect size socket will result in inaccurate and inconsistent
fastening torque and/or damage to the bolt or nut.
Installing or removing socket (Fig. 3 & 4)
CAUTION:
Always be sure that the tool is switched off and the battery
cartridge is removed before installing or removing the socket.
1. For socket without O-ring and pin
To install the socket, push it onto the anvil of the tool until
it locks into place.
To remove the socket, simply pull it off.
Auto-stop setting for number of impacts (Fig. 7)
This tool has a convenient auto-stop mechanism that allows you to preset the desired number of impacts in terms of the
application. The tool then stops automatically after reaching the preset number of impacts.
1. To set the dial on the back of the tool, first slide out the battery cartridge by sliding the button on the side of the cartridge.
2. Two dials can be seen on the battery holder side. Use a slotted screwdriver to set the dial to a desired 2-digit setting.
3. You cannot set the auto-stop setting for fastening with more than 200 impacts (over 4 sec.)
Note:
Do not force the dial when turning. You might break it.

Clockwise
Tool stops after the twice the
set number of impacts is
reached. See the next sec-
tion for the appropriate fas-
tening torque.
Pull the trigger to start the tool; release it to stop.
No rotation even with trigger
pulled.
2. For socket with O-ring and pin
Move the O-ring out of the groove in the socket and
remove the pin from the socket. Fit the socket onto the
anvil of the tool so that the hole in the socket is aligned
with the hole in the anvil. Insert the pin through the hole in
the socket and anvil. Then return the O-ring to the original
position in the socket groove to retain the pin. To remove
the socket, follow the installation procedures in reverse.
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 counterclockwise
rotation. When the reversing switch lever is in the neutral
position, the switch trigger cannot be pulled.
Counterclockwise
Pull the trigger to start the
tool; release it to stop.
Pull the trigger to start the
tool; release it to stop.
