Maintenance - DeWalt DCF900 Instruction Manual

nOTE: The first time the tool is run after changing the
direction of rotation, you may hear a click on start up. This is
normal and does not indicate a problem.
Worklight (Fig. A, B)
The worklight 7 is activated when the variable
speed trigger 1 is depressed. Pressing the worklight
switch 8 repeatedly will cycle through low illumination,
high illumination, and off.
nOTE: The worklight is for lighting the immediate work
surface and is not intended to be used as a flashlight.
Usage (Fig. A)

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 variable speed trigger switch
Release variable speed trigger 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 recommended could cause the fasteners to be
overstressed, stripped or damaged.
