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 pressing the buttons on both sides 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 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.
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
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.
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.
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
For socket with O-ring and pin
Fig.5
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.
For socket without O-ring and pin
Fig.6
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.
OPERATION
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.
