The appropriate tightening torque may vary depending on the type or size of the screw,
the material of the part to be fastened, etc.
The relationship between tightening torque and tightening time is as follows.
Proper tightening torque for standard screw
1. Fixture time (second) 2. Tightening torque
Proper tightening torque for high tenacity bolt
1. Fixture time (second) 2. Tightening torque
Keep the tool pointed directly at the bolt or nut.
Excessive tightening torque can damage the nut or impact socket. Before starting your
job, always do a trial run to determine the proper tightening time for your bolt or nut.
If the tool is used continuously until the battery cartridge is discharged, let the tool rest
for 15 minutes before proceeding with a new battery cartridge.
After fixing, always check the tightening torque with a torque wrench. Tightening torque
is affected by a wide variety of factors, including the following:
•
When the battery cartridge is almost fully discharged, the voltage will drop and
the tightening torque will decrease.
• impact socket
o
If the correct size impact wrench is not used, the tightening torque will be
reduced.
o
A worn impact socket (hex or square end wear) will cause a reduction in
torque.
