Fastening torque
NOTE:
Hold the tool pointed straight at the bolt or nut.
NOTE:
Excessive fastening torque may damage the
bolt/nut or impact socket. Before starting your job,
always perform a test operation to determine the
proper fastening time for your bolt or nut.
NOTE:
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
cartridge.
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
completely, voltage will drop and the fastening
torque will be reduced.
2. Impact socket
•
Failure to use the correct size impact socket
will cause a reduction in the fastening torque.
•
A worn impact socket (wear on the hex end
or square end) will cause a reduction in the
fastening torque.
