MAINTENANCE
WARNING: To reduce the risk of serious personal injury, place
the forward/reverse button in the lock-off position or turn tool
off and disconnect battery pack before making any adjustments
or removing/installing attachments or accessories.
Cleaning
WARNING:
Blow dirt and dust out of all air vents with clean, dry air
at least once a week. To minimize the risk of eye injury, always wear
ANSI Z87.1 approved eye protection when performing this.
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.
CHARGER CLEANING INSTRUCTIONS
WARNING:
Shock hazard. Disconnect the charger from the AC
outlet before cleaning. Dirt and grease may be removed from the
exterior of the charger using a cloth or soft non-metallic brush.
Do not use water or any cleaning solutions.

accessories with this tool could be hazardous. To reduce the risk of
injury, only D
E
WALT recommended accessories should be used with
this product.

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 socket 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.
•
Socket size:
Failure to use the correct socket 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.
