*2 How to use the LED light
To prevent the battery power consumption caused
by forgetting to turn off the LED light, the light goes off
automatically in about 10 seconds.
*3 Tightening mode selector function
CAUTION
Select tightening mode while the trigger switch is
released. Failure to do so could result in malfunction.
NOTE
○ The appropriate mode will vary depending on the screw
and the material being screwed. Adjust the tightening
mode setting by test-tightening a number of screws.
○ The tightening mode cannot be changed unless the
rechargeable battery has been mounted in the tool and
the switch has been pulled.
(1) High / Low mode selector switch (Fig. 13)
The tightening mode switches between 4 diff erent
rotation speeds each time the High / Low mode selector
switch is pressed.
(2) Auto stop mode selector switch (Fig. 14)
Each time the auto stop mode selector switch is pressed,
the auto stop function will switch between ON and OFF.

USE:
For work of loosening bolts or nuts.
This function helps prevent nuts from dropping when
loosening them.
NOTE
Depending on factors such as the bolt or nut size, socket
used, and extent of tightening, there is a risk of nuts
accidentally dropping if the nut becomes detached from
the screw thread while the power tool is operating.
MAINTENANCE AND INSPECTION
1. Inspecting the socket
A worn or deformed hex. or a square-holed socket will
not give an adequate tightness to the fi tting between
the nut or anvil, consequently resulting in loss of
tightening torque. Pay attention to wear of a socket holes
periodically, and replace with a new one if needed.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that
they are properly tightened. Should any of the screws be
loose, retighten them immediately. Failure to do so could
result in serious hazard.
3. Maintenance of the motor
The motor unit winding is the very "heart" of the power
tool. Exercise due care to ensure the winding does not
become damaged and/or wet with oil or water.
4. Inspection of terminals (tool and battery)
Check to make sure that swarf and dust have not
collected on the terminals.
On occasion check prior, during and after operation.
CAUTION
Remove any swarf or dust which may have collected on
the terminals.
Failure to do so may result in malfunction.
5. Cleaning on the outside
When the tool is stained, wipe with a soft dry cloth or
a cloth moistened with soapy water. Do not use chloric
solvents, gasoline or paint thinner, for they melt plastics.
