SEQUENTIAL TRIP SAFETY OPERATION
The model 475
fl
ooring stapler operates on a sequen
ti
al trip system. The sequen
ti
al
trip system requires the operator to hold the tool against the work before pulling
the trigger. This makes accurate fastener placement easier. The sequen
ti
al trip
allows exact fastener loca
ti
on without the possibility of driving a second fastener on
recoil. The sequen
ti
al trip system has a posi
ti
ve safety advantage because it will not
accidentally drive a fastener if the tool is contacted against the work – or anything
else – while the operator is holding the trigger pulled.
TOOL OPERATION CHECK:
CAUTION: Remove all fasteners from tool before performing tool opera
ti
on check.
SEQUENTIAL TRIP OPERATION:
A.
Press the contact trip against the work surface, without touching the trigger.
THE TOOL MUST NOT CYCLE.
B.
Hold the tool o
ff
the work surface and pull the trigger.
THE TOOL MUST NOT CYCLE.
Release the trigger. The trigger must return to the trigger stop on the frame.
C.
Pull the trigger and press the contact trip against the work surface.
THE TOOL MUST NOT CYCLE.
D.
With
fi
nger o
ff
the trigger, press the contact trip against the work surface. Pull
the trigger.
THE TOOL MUST CYCLE.

TOOL AIR FITTING:
This tool uses a free-
fl
ow connector plug, 1/4 NPT. The inside diameter should be
.200” (5mm) or larger. The
fi
tti
ng must be capable of discharging tool air pressure
when disconnected from the air supply.
OPERATING PRESSURE:
70 to 100 PSI
G
. (4.8 to 7.0 kg/cm2). Select the opera
ti
ng pressure within this range
for best fastener performance.
DO NOT EXCEED THE RECOMMENDED OPERATING
PRESSURE.
AIR CONSUMPTION:
The model 475 requires 3.1 cubic feet per minute (.09 cubic meters) of free air to
operate at the rate of 100 fasteners per minute, at 80 PSI (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 fasteners per minute, you need 50% of
the tool’s C.F.M. which is required to operate the tool at 100 fasteners per minute.
SEQUENTIAL TRIP OPERATION:
The model 475

LUBRICATION
Apply one or two drops of Air Tool Lubricant, Mobil Velocite #10, or equivalent prior
to each use. Use more or less frequently depending on usage and duty cycle
