2. Press switch to start operation. Always check torque with a
torque wrench, as the fastening torque is affected by many factors
including the following:
• Voltage: Low voltage, due to a nearly discharged battery, will
reduce fastening torque.
• Socket size: Failure to use the correct socket size will cause a
reduction in fastening torque.
• Bolt Size: Larger bolt diameters generally require higher
fastening torque. Fastening torque will also vary according to
length, grade, and torque coefficient.
• Bolt: Ensure that all threads are free of rust and other debris to
allow proper fastening torque.
• Material: The type of material and surface finish of the material
will affect fastening torque.
• Fastening Time: Longer fasten ing time results in increased
fastening torque. Using a longer fastening time than recom-
mended could cause the fasteners to be overstressed, stripped
or damaged.
