AIR CONSUMPTION:
The BTF83C requires 6.4 cubic feet per minute (181 liters per minute) of free air to operate in sequential trip
mode at the rate of 100 nails per minute, at 80 p.s.i.g (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 6.4 c.f.m. (181 liters per minute) which is required to operate the tool at 100
nails per minute.
OPERATING MODES
BOSTITCH OFFERS TWO MODES OF OPERATION FOR THIS TOOL.
SEQUENTIAL TRIP:
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:
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.
MODE IDENTIFICATION:
Refer to Tool Operation Instructions on pages 9-11 before proceeding to use this tool.
TO CHANGE OPERATING MODES:
Disconnect air line from tool and remove fasteners from magazine before making
adjustments or personal injury may result.
Always know the tool operating mode before connecting to an air supply and/or using the
tool.
SEQUENTIAL TRIP-
1. Push and hold in pivot pin opposite the selector, while rotating the selector 180° counterclockwise to the
sequential trip position .
2. Ensure the selector is fully seated in the new position.
