Straight head and ratchet head (optional

accessory)

Straight heads and ratchet heads are available as optional

accessories for various applications on the job.

OPERATION

The proper fastening torque may differ depending upon the

kind or size of the screw/bolt, the material of the workpiece to

be fastened, etc. Before starting your job, always perform a

test operation to determine the proper fastening time for your

screw.

NOTE:

• Use the proper bit for the head of the screw/bolt that you

wish to use.

• Hold the tool pointed straight at the screw.

• If the tool is operated continuously until the battery

cartridge has discharged, allow the tool to rest for 15

minutes before proceeding with a fresh battery.

The fastening torque is affected by a wide variety of factors

including the following. After fastening, always check the

torque with a torque wrench.

1. When the battery cartridge is discharged almost com-

pletely, voltage will drop and the fastening torque will be

reduced.

2. Driver bit or socket bit

Failure to use the correct size driver bit or socket bit will

cause a reduction in the fastening torque.
