Battery protection system (Lithium-ion
battery with star marking) (Fig. 2)
Lithium-ion batteries with a star marking are equipped
with a protection system. This system automatically cuts
off power to the tool to extend battery life.
The tool will automatically stop during operation if the tool
and/or battery are placed under one of the following
conditions:
• Overloaded:
The tool is operated in a manner that causes it to
draw an abnormally high current.
In this situation, release the trigger switch on the tool
and stop the application that caused the tool to
become overloaded. Then pull the trigger switch
again to restart.
If the tool does not start, the battery is overheated. In
this situation, let the battery cool before pulling the
trigger switch again.
• Low battery voltage:
The remaining battery capacity is too low and the tool
will not operate. In this situation, remove and
recharge the battery.
Indicating the remaining battery capacity
Only for battery cartridges with the indicator (Fig. 3)
Press the check button on the battery cartridge to indicate
the remaining battery capacity. The indicator lamps light
up for a few seconds.
NOTE:
• Depending on the conditions of use and the ambient
temperature, the indication may differ slightly from the
actual capacity.
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. 4)
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. 5)
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. 6)
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. 7)
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. 8)
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.
