Stall Release (Fig. 12)
If the nailer is used in harder wood where all available energy in the motor

E
is used to drive a fastener, the tool may stall. The driver blade will not
complete the drive cycle and the jam/stall indicator will flash. Rotate the
stall release lever (E) on the tool and the mechanism will release. NOTE:
The tool will disable itself and not reset until the battery pack has been
removed and reinserted. If the driver blade does not automatically return
to the home position, proceed to Clearing a Jammed Nail. If the unit
continues to stall please review the material and fastener length to be
sure that it is not too rigorous an application.

Cold Weather Operation
When operating tools at temperatures below freezing:
1. Keep tool as warm as possible prior to use.
2. Actuate the tool 10 or 15 times into scrap lumber before using.

on the battery pack but may be easily knocked over.
The D
EWALT cordless nailer includes a rotating rafter hook (J) and can be
easily positioned to the left or right of the tool to accommodate left- or right-

tool before making any adjustments, changing accessories, servicing, or moving the tool.
Such preventative safety measures reduce the risk of starting the tool accidentally.
Daily Maintenance Chart
ACTION Clean magazine, pusher, and contact trip mechanism.
WHY Permits smooth operation of magazine, reduces wear, and prevents jams.
HOW Blowing off the tool with compressed air is the most effective way to clean the tool.
The use of oils, lubricants periodically or solvents is not recommended as they tend to
attract debris and/or damage the plastic parts of the tool.
ACTION Before each use, check to ensure all screws and fasteners are tight and undamaged.
WHY Prevents jams and premature failure of tool parts.
HOW Tighten loose screws using the appropriate hex wrench or screwdriver.
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.
NOTICE: When cleaning, use only a damp cloth on plastic parts. Many household cleaners contain
chemicals which could seriously damage plastic parts. Also, do not use gasoline, turpentine, lacquer
or paint thinner, dry cleaning fluids or similar products which may seriously damage plastic parts.
Never let any liquid get inside the tool; never immerse any part of the tool into a liquid.
CHARGER CLEANING INSTRUCTIONS

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.
Lubrication
