Cold Weather Operation

When operating tools at temperatures below freezing:

1. Keep tool as warm as possible prior to use.
2. Actuate the tool 5 or 6 times into scrap lumber before

using.

Hot Weather Operation

Tool should operate normally. However, keep tool out of direct
sunlight as excessive heat can deteriorate bumpers and other
rubber parts resulting in increased maintenance.

The D

E

WALT cordless nailers include an

integrated suspension hook (J) and can be
attached to either side of the tool to accom-
modate left- or right-handed users.
If the hook is not desired at all, it can be
removed from the tool.

TO REMOVE SUSPENSION HOOK

1. Remove battery pack from tool.
2. To switch the tool from right- to left-hand usage simply

remove the screw from the opposite side of the tool and
reassemble on the other side.

3. Replace battery pack. 

WARNING: 

Remove nails from magazine before making

any adjustments or servicing this tool. Failure to do so may
result in serious injury.

CAUTION: Disconnect battery pack from tool before

making any adjustments, changing accessories, servic-
ing, or moving the tool.

Such preventative safety measures

reduce the risk of starting the tool accidentally.

CAUTION: When not in use, place tool on its side on a

stable surface where it will not cause a tripping or falling
hazard. 

Some tools with large battery packs will stand

upright on the battery pack but may be easily knocked over. 

MAINTENANCE

Daily Maintenance Chart

ACTION

Clean magazine, pusher, and contact trip mechanism.

WHY

Permits smooth operation of magazine, reduces wear,
and prevents jams. 

HOW

Blow clean with compressor air. The use of oils, lubri-
cants periodically or solvents is not recommended as
they tend to attract debris.

ACTION

Before each use, check to insure all screws, nuts and
fasteners are tight and undamaged. 

WHY

Prevents jams and premature failure of tool parts.

HOW

Tighten loose screws or other fasteners using the
appropriate allen wrench or screwdriver. 

Cleaning

Use only mild soap and a damp cloth to clean the tool. Many
household cleaners contain chemicals which could seriously
damage plastic. Also, do not use gasoline, turpentine, lac-
quer or paint thinner, dry cleaning fluids or similar products.
