of eye injury, always wear ANSI Z87.1 approved eye
protection when performing thisprocedure.

WARNING: Never use solvents or other harsh
chemicals for cleaning the non‑metallic parts of the
tool. These chemicals may weaken the plastic materials
used in these parts. Use a cloth dampened only with
water and mild soap. Never let any liquid get inside the
tool; never immerse any part of the tool into aliquid.

accidental start‑up can causeinjury.
Your DeWALT power tool has been designed to operate
over a long period of time with a minimum of maintenance.
Continuous satisfactory operation depends upon proper tool
care and regularcleaning.

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.
