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.
