Maintenance; Protecting The Environment - DeWalt DCF809 Original Instructions Manual

DCF809 190
CAUTION: Ensure fastener and/or system will
withstand the level of torque generated by the tool.
Excessive torque may cause breakage and possible
personal injury.
1. Place the accessory on the fastener head. Keep the
tool pointed straight at the fastener.
2. Press switch to start operation. Release the switch to
stop 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.
• Accessory size: Failure to use the correct
accessory 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.
