F SERIESTOOL SPECIFICATIONS
All screws and nuts are metric.
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/F21PL2:
- with standard framing contact arm installed: Uses a 21° plastic collated fullround head stick nails, in lengths
of 2”to 3-1/2”(50-90mm) and shank diameters of.113”to .162” (2.8 - 4.1mm)
- (Included with F21PL ONLY) 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”.
- MCN-KIT3 must be purchased separately for the F21PL2 to be used for fastening metal connectors.
NOTE:Use only one stick of metal connectornails at a time.
F33PT/ F33PTSM:
- with standard framing contact arm installed: Uses a 33° paper collated stick nails, in lengths of2”to 3-1/2”(50-
90mm) and shank diameters of .113”to .131”(2.8 - 3.3mm)
- with metal connector attachment installed: Uses a35° paper collated fullround 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/cm
2
).Select the operating pressure within this range for best fastener performance.
DO NOT EXCEEDTHIS RECOMMENDED OPERATING PRESSURE.
AIR CONSUMPTION:
The F21PL /F21PL2 / F28WW / F33PT / F33PTSM requires 8.7 cubic feet per minute (247 liters per minute) of free
air to operate at the rate of 100 nails per minute, at 80 p.s.i.(5.6 kg/cm
2
).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,
youneed 50% of the 8.7 c.f.m. (247 liters per minute) which is required to operate the tool at 100 nails per minute.
OPERATION
BOSTITCH OFFERS TWO MODES OF OPERATION FORTHIS SERIES TOOL.
SEQUENTIALTRIP (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 secondfastenerif the tool is contacted against the work– or anything else – while the operator
is holding the trigger pulled.
CONTACTTRIP (Black trigger):
The common operating 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 is
contacted. This will allow rapid fastener placement on many jobs, such as sheathing, decking and pallet
assembly.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
trigger pulled) an unwanted second fastener will be driven.
