Reversing switch action

011494

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.

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

011495

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.

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.

Selecting the action mode

011496

This tool employs an action mode changing ring. Select

one of the three modes suitable for your work needs by

using this ring.

For rotation only, turn the ring so that the arrow on the

tool body points toward the

mark on the ring.

For rotation with hammering, turn the ring so that the

arrow points toward the

mark on the ring.

For rotation with clutch, turn the ring so that the arrow

points toward the

mark on the ring.

CAUTION:

•

Always set the ring correctly to your desired mode

mark. If you operate the tool with the ring positioned

halfway between the mode marks, the tool may be

damaged.

Adjusting the fastening torque

011496

The fastening torque can be adjusted in 16 steps by

turning the adjusting ring so that the graduations are

aligned with the arrow on the tool body. The fastening

torque is minimum when the number 1 is aligned with the

arrow, and maximum when the number 16 is aligned with

the arrow.

Before the 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.

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.
