Maintenance - DeWalt DCF889-XE Instruction Manual

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 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.
