screw is not damaged.
• Hold the tool pointed straight at the screw.
• If you tighten the screw for a time longer than
shown in the figures, the screw or the point of the
driver bit may be overstressed, stripped, damaged,
etc. Before starting your job, always perform a test
operation to determine the proper fastening time
for your screw.
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. Driver bit or socket bit
Failure to use the correct size driver bit or socket
bit will cause a reduction in the fastening torque.
2. Bolt
• Even though the torque coefficient and the
class of bolt are the same, the proper
fastening torque will differ according to the
diameter of bolt.
• Even though the diameters of bolts are the
same, the proper fastening torque will differ
according to the torque coefficient, the class of
bolt and the bolt length.
3. The manner of holding the tool or the material of
driving position to be fastened will affect the
torque.
4. Operating the tool at low speed will cause a
reduction in the fastening torque.
MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and
