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.
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.
Speed change
Fig.5
To change the speed, first switch off the tool and then
slide the speed change lever to the "2" side for high
speed or "1" side for low speed. Be sure that the speed
change lever is set to the correct position before
operation. Use the right speed for your job.
CAUTION:
Always set the speed change lever fully to the
•
correct position. If you operate the tool with the
speed change lever positioned halfway between
the "1" side and "2" side, the tool may be damaged.
Do not use the speed change lever while the tool is
•
running. The tool may be damaged.
Adjusting the fastening torque
Fig.6
The fastening torque can be adjusted in 17 steps by
turning the adjusting ring so that its graduations are
aligned with the pointer on the tool body. The fastening
torque is minimum when the number 1 is aligned with the
pointer, and maximum when the
with the pointer.
The clutch will slip at various torque levels when set at
the number 1 to 16. The clutch is designed not to slip at
the marking.
