Mode Selection
WARNING: Always wear proper eye [ANSI Z87.1 (CAN/CSA
Z94.3)] and hearing protection [ANSI S12.6 (S3.19)] when operating
this tool.
WARNING: Keep fingers AWAY from trigger when not driving
fasteners to avoid accidental firing. NEVER carry tool with finger on
trigger. In contact mode tool will fire a fastener if safety is bumped
while trigger is depressed.
The DWFP12233 features a selectable trigger system that allows the
user to choose between the following modes of operation
Sequential Trip
The Sequential Trip requires the operator to hold the tool against
the work before pulling the trigger. This makes accurate fastener
placement easier. The Sequential Trip allows exact fastener location
without the possibility if driving a second fastener on recoil as
described under Contact Trip. The Sequential Trip Tool has a
positive advantage because it will not accidentally drive a fastener
if the tool is contacted against the work surface - or anything else -
while the operator is holding the trigger pulled.
Bump/Contact Trip
The common operation procedure on "Contact Trip" tools is for
the operator to contact the work surface to actuate the trip
mechanism while keeping the trigger pulled, thus driving a fastener
each time the work surface is contacted. This will allow rapid
fastener placement on many jobs. All pneumatic tools are subject
to recoil when driving fasteners. The tool may bounce, releasing the
trip, and if unintentionally allowed to re-contact the work surface
with the trigger still actuated (finger still holding the trigger pulled) an
unwanted second fastener will be driven.
TO CHANGE OPERATING MODES (FIG. 1–3)
WARNING: Disconnect air line from tool and remove fasteners
from magazine before making adjustments or personal injury may
result.
SEQUENTIAL TRIP ACTION
Use sequential action for intermittent nailing where very careful and
accurate placement is desired.
To operate the nailer in sequential action
mode:
1. Rotate the trigger mode selector (B)
clockwise to the sequential action position
, as shown in Figure 2.
2. Fully depress nosepiece against the work
surface.
3. Pull trigger.
4. Release trigger.
5. Lift nosepiece off work surface.
6. Repeat steps 2 through 4 for next application.
WARNING: The contact trip needs to be depressed followed by a
trigger pull for each fastener followed by a release of both the contact
trip and trigger after each fastener.
CONTACT TRIP ACTION
Bump/contact action is intended for rapid nailing on flat, stationary
surfaces.
When using bump action, two methods are available: place
actuation and bump actuation.
