MIII TOOL SPECIFICATIONS
All screws and nuts are metric.
FASTENER SPECIFICATIONS:
TOOL
AIR FITTING:
This tool uses a 3/8” 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:
60 to 100 p.s.i.g. (4.2 to 7.1 kg/cm2). Select the operating pressure within this range for best
fastener performance.
DO NOT EXCEED THE RECOMMENDED OPERATING PRESSURE.
AIR CONSUMPTION:
The MIII requires 7.1 cubic feet per minute (201 liters per minute) of free air to operate at the rate of 100
fasteners 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 fasteners per minute, you need
50% of the tool’s c.f.m. of free air which is required to operate the tool at 100 fasteners per minute.
OPERATION
BOSTITCH OFFERS TWO TYPES OF OPERATION FOR THIS SERIES TOOL.
CONT
ACT TRIP:
The common operating procedure on “Contact Trip” tools is for the operator to contact the work 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 recontact the work surface with the trigger still actuated (finger still holding trigger
pulled) an unwanted second fastener will be driven.
TRIGGER OPERATED:
The Trigger Operated model is cycled by actuation of the trigger only. This model does not have a Contact
Arm and is intended for use only where a Contact Arm CANNOT be used to satisfy the requirements of the
application. The Trigger Operated tool will cycle each time the trigger is actuated.
MODEL IDENTIFICATION:
Refer to Operation Instructions on page 8 before proceeding to use this tool.
