OPERATING INSTRUCTIONS
The fastening torque is affected by a wide variety of factors, including the following:
• Socket
- Failure to use the correct size socket will cause a reduction in the fastening torque. A worn
socket (wear on the hex end or square end) will cause a reduction in the fastening torque.
• Bolt
- Although the torque coefficient and the class of bolt may be the same, the proper fastening
torque will differ according to the diameter of the bolt. Although the diameters of bolts may be
the same, the proper fastening torque will differ according to the torque coefficient, the class of
bolt and the bolt length.
• The use of a universal joint or an extension bar (both sold separately) will reduce the fastening
force of the impact wrench somewhat. Compensate by fastening for a longer period of time.
• The manner of holding the tool or the material to be fastened will affect the torque.
Loosening Fasteners
The torque that is required to loosen a fastener averages 75% to 80% of the tightening torque,
depending on the condition of the contacting surfaces. However, if rust or corrosion causes
seizing, more torque may be required.
CARE AND MAINTENANCE
All maintenance should only be carried out by a qualified technician.
Cleaning
Before cleaning or performing any maintenance, remove the battery pack from the impact wrench.
For safe and proper operation, always keep the tool and its ventilation slots clean.
Always use only a soft, dry cloth to clean your impact wrench; never use detergent or alcohol.
