ASSEMBLY
WARNING: Disconnect air line from tool, engage trigger lock and remove
fasteners from magazine before making adjustments or personal injury may
result.
TRIGGER
WARNING: Keep fingers AWAY from the trigger when not driving fasteners to avoid
accidental actuation. Never carry a tool with finger on the trigger. In bump action mode
(contact actuation mode), the tool will drive a fastener if the contact trip is bumped
while the trigger is depressed.
The DWFP12658 is equipped with a selectable trigger. This trigger allows the
operator to select either single sequential action trigger mode or bump action trigger
mode. In accordance with the ANSI Standard SNT-101-2002, the trigger is assembled
in the single sequential action trigger mode. To change the trigger mode, see Actuating
Tool instructions in the Operation section of the manual. The selectable trigger also has
a trigger lock button to keep the trigger locked at all times when the tool is not in use.
AIR FITTING
The tool is equipped with a 1/4" (6.4 mm) male quick connector coupling. A 3/8"
(9.5 mm) male quick connector coupling is available from D
e
WALT and may be used
when a 1/4" (6.4 mm) supply line is not available.
NOTE: A 3/8" (9.5 mm) supply line (and fittings) are required for maximum tool
performance.
WARNING: Always use couplings that relieve all pressure from the tool when it is
disconnected from the power supply. Always use hose connectors that shut off air
supply from compressor when the tool is disconnected.
To install an air fitting
1. Wrap the male end of the fitting with thread seal tape prior to assembly to eliminate
air leaks.
2. To install a 1/4" (6.4 mm) fitting: screw it directly into the air inlet and tighten firmly.
NOTE: If an adapter is in the air inlet, remove it prior to inserting the fitting.
3. To install a 3/8" (9.5 mm) fitting: screw the fitting into the 3/8" (9.5 mm) adapter and
then into the air inlet of the tool and tighten firmly.
