SAVE THESE INSTRUCTIONS.
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.
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 sliding the push button on the front 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 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.
Lighting up the front lamp (Fig. 3)
CAUTION:
• Do not look in the light or see the source of light
directly.
Pull the switch trigger to light up the lamp. The lamp
keeps on lighting while the switch trigger is being pulled.
The light automatically goes out 10 – 15 seconds after
the switch trigger is released.
NOTE:
• Use a dry cloth to wipe the dirt off the lens of lamp. Be
careful not to scratch the lens of lamp, or it may lower
the illumination.
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 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.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and the bat-
tery cartridge is removed before carrying out any work
on the tool.
Selecting correct socket
Always use the correct size socket for bolts and nuts. An
incorrect size socket will result in inaccurate and incon-
sistent fastening torque and/or damage to the bolt or nut.
Installing or removing socket
1.
For socket without O-ring and pin
(Fig. 5)
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.
2.
For socket with O-ring and pin
(Fig. 6)
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.
Hook (Fig. 7)
The hook is convenient for temporarily hanging the tool.
This can be installed on either side of the tool.
To install the hook, insert it into a groove in the tool hous-
ing on either side and then secure it with a screw. To
remove, loosen the screw and then take it out.
OPERATION
CAUTION:
• Always insert the battery cartridge all the way until it
locks in place. 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.
Hold the tool firmly and place the socket over the bolt or
nut. Turn the tool on and fasten for the proper fastening
time.
(Fig. 8)
The proper fastening torque may differ depending upon
the kind or size of the bolt, the material of the workpiece
to be fastened, etc. The relation between fastening
torque and fastening time is shown in the figures.
