FASTENER SPECIFICATIONS:
F28WW: Uses a 28° wire collated stick nail in lengths of 2" to 3-1/2" (50 - 90mm) and shank diameters of .113" to
.131" (2.8 - 3.3mm)
F21PL:
- with standard framing contact arm installed: Uses a 21° plastic collated full round head stick nails, in lengths
of 2" to 3-1/2" (50-90mm) and shank diameters of .113" to .162" (2.8 - 4.1mm)
- with metal connector attachment installed: Uses a 23° plastic collated full round head metal connector nails, in
lengths of 1-1/2" and 2-1/2" (38 - 64mm) and shank diameters of .131", .148" and .162".
NOTE: Use only one stick of metal connector nails at a time.
F33PT:
- with standard framing contact arm installed: Uses a 33° paper collated stick nails, in lengths of 2" to 3-1/2" (50-
90mm) and shank diameters of .113" to .131" (2.8 - 3.3mm)
- with metal connector attachment installed: Uses a 35° paper collated full round head metal connector nails,
in lengths of 1-1/2" and 2-1/2" (38 - 64mm) and shank diameters of .131", .148" and .162".
NOTE: Use only one stick of metal connector nails at a time.
TOOL AIR FITTING:
This tool uses a 1/4" N.P.T. male plug. The inside diameter should be .275" (7mm) or larger. The fitting must be
capable of discharging tool air pressure when disconnected from the air supply.
OPERATING PRESSURE:
70 to 120 p.s.i.g. (4.9 to 8.4 kg/cm2). Select the operating pressure within this range for best fastener performance.
DO NOT EXCEED THIS RECOMMENDED OPERATING PRESSURE.
AIR CONSUMPTION:
The F21PL / F28WW / F33PT requires 7.5 cubic feet per minute (212 liters per minute) of free air to operate at the
rate of 100 nails per minute, at 80 p.s.i. (5.6 kg/cm2). Take the actual rate at which the tool will be run to determine
the amount of air required. For instance, if your fastener usage averages 50 nails per minute, you need 50% of the
7.5 c.f.m. (212 liters per minute) which is required to operate the tool at 100 nails per minute.
OPERATION
BOSTITCH OFFERS THREE MODES OF OPERATION FOR THIS SERIES TOOL.
SEQUENTIAL TRIP (Gray trigger):
The Sequential Trip requires the operator to hold the tool against the work surface before pulling the trigger. This
makes accurate fastener placement easier, for instance on framing, toe nailing and crating applications.The
Sequential Trip allows exact fastener placement without the possibility of driving a second fastener on recoil, as
described under "Contact Trip". The Sequential Trip Tool has a positive safety advantage because it will not
accidentally drive a second fastener if the tool is contacted against the work – or anything else – while the operator
is holding the trigger pulled.
CONTACT TRIP "Smart Mode" (Black trigger):
The "Smart Trigger" assembly that came with this tool allows you to operate the tool as either Sequential or Contact
Trip, depending upon the order in which you pull the trigger. The "Smart Trigger" mode of operation allows the user
to decide whether the tool will fire once or multiple times with the trigger depressed. For instance: If you pull the
trigger first (and hold), each time you press the tool against the wood it will cycle, like a contact trip (black trigger).
If you press the tool FULLY against the wood, THEN pull the trigger, the tool will only drive one nail. If the tool is
lifted up and pushed against the wood a second time, it will not drive a second nail. Like the Sequential Trip
Operation (gray trigger).
