ll screws and nuts are metric.
- Uses a 21° plastic collated full round head stick nails, in lengths of 2” to 3-1/4” (50-83mm) and shank diameters of
.113” to .148” (2.8 - 3.8mm)
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.
70 to 120 p.s.i.g. (4.9 to 8.4 kg/cm
). Select the operating pressure within this range for best fastener performance.
DO NOT EXCEED THIS RECOMMENDED OPERATING PRESSURE.
The LPF21PL 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/cm
). 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.
BOSTITCH OFFERS TWO MODES OF OPERATION FOR THIS TOOL.
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.
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.
