Care And Maintenance - Kobalt 6904 Mode D'emploi

OPERATION INSTRUCTIONS
• The use of a universal joint or an extension bar (both available 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 with the Impact Wrench
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

WARNING
• To ensure safety and reliability, all repairs should be performed by a qualified service
technician.
• When servicing, use only identical replacement parts. The use of any other parts may create
a hazard or cause damage to the product.
• Unplug the impact wrench from the power source before cleaning or performing any
maintenance.
Before each use:
• Inspect the impact wrench, the switch, and the cord for damage.
• Check for damaged, missing, or worn parts.
• Check for loose screws, misalignment or binding of moving parts, or any other condition that
may affect the operation.
• If abnormal vibration or noise occurs, turn the impact wrench off immediately, and have the
problem corrected before further use.
Using compressed air may be the most effective cleaning method. Always wear safety goggles
when cleaning tools with compressed air.
WARNING
• Do not allow brake fluids, gasoline, petroleum-based products, penetrating oil, etc. to come
into contact with plastic parts. These substances contain chemicals that can damage,
weaken, or destroy plastic.
