lined above and follow the directions below.
1. Make sure compressor tanks have been properly drained prior to use. Always drain the
compressor tanks at least once daily while using the nailer. This is especially important in
cold weather because any moisture in the air in the tanks will condense in the cold tem-
perature.
2. Keep the tool as warm as possible prior to use.
3. Put 5 to 10 drops of D
WALT Pneumatic Tool Oil or winter weight pneumatic oil containing
E
ethylene glycol in the end cap.

[ANSI S12.6 (S3.19)] when operating this tool.
The tool can be actuated using one of two modes: single sequential action trigger mode and
bump action trigger mode. The trigger installed on the tool as described in the Trigger section
of this manual determines the mode of operation.
SEQUENTIAL ACTION TRIGGER -
The sequential action trigger's intended use is for intermittent nailing where very careful and
accurate placement is desired.
To operate the nailer in sequential action mode:
1. Depress the contact trip firmly against the work surface.
2. Depress the trigger.
CAUTION: A nail will fire each time the trigger is depressed as long as the contact trip
remains depressed.
