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.
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.

speed change lever positioned halfway between
the "1" side and "2" side, the tool may be
damaged.

•
is running. The tool may be damaged.
If the tool speed is coming down extremely during

To change the speed, switch off the tool first. Select the
"2" side for high speed or "1" for low speed but high
torque. Be sure that the speed change lever is set to the
correct position before operation.

Adjusting the fastening torque

013960
The fastening torque can be adjusted in 17 steps by
turning the adjusting ring. Align the graduations with the
arrow on the tool body. You can get the minimum
fastening torque at 1 and maximum torque at
marking.
The clutch will slip at various torque levels when set at
the number 1 to 16. The clutch does not work at
the marking.
Before actual operation, drive a trial screw into your
material or a piece of duplicate material to determine
which torque level is required for a particular application.
The following shows the rough guide of the relationship
between the screw size and graduation.
