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.
SAVE THESE INSTRUCTIONS.
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
CAUTION:
• Before inserting the battery cartridge into the tool,
always check to see that the switch lever actuates
properly and returns to the "OFF" position when
released. (Fig. 2)
To start the tool, simply pull the switch lever. Tool speed is
increased by increasing pressure on the switch lever.
Release the switch lever to stop.
Lighting up the front lamp
CAUTION:
• Do not look in the light or see the source of light
directly. (Fig. 3)
Pull the switch lever to light up the lamp. The lamp keeps
on lighting while the switch lever is being pulled. The light
automatically goes out 10 - 15 seconds after the switch
lever 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
counterclockwise rotation.
When the reversing switch lever is in the neutral position,
the switch lever 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 (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.
Hook (Accessory)
CAUTION:
• When installing the hook, tighten the screw firmly.
Failure to do so may cause the breakage of the tool or
personal injury. (Fig. 6)
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
housing on either side and then secure it with a screw.
To remove, loosen the screw and then take it out.
Adjusting the angle head
The angle head can be adjusted 360° (8 positions in 45-
degree increments). To adjust it, loosen the hex bolt and
remove the angle head.
Adjust the angle head to the desired position and reinstall
it so that the teeth on the housing will match up with the
grooves in the angle head. Then tighten the hex bolt to
secure the angle head. (Fig. 7 & 8)
