Loading Tool (con't.)

· Check operation of the contact arm mechanism frequently.  Do not use the tool if the arm
is not working correctly as accidental driving of a fastener may result.  Do not interfere with
the proper operation of the contact arm mechanism.
· Do not drive fasteners on top of other fasteners or with the tool at an overly steep angle, 
as this may cause deflection of fasteners which could cause injury.
· Do not drive fasteners close to the edge of the work piece as the wood may split, allowing
the fastener to be deflected, possibly causing an injury.

Maintenance

When working on air tools, note the warnings in this manual and use extra care when
evaluating problem tools.

SPECIFICATIONS

· Fasteners:  15-1/2 gauge, 1/2" crown staples from 1-1/2" to 2" long
· Magazine capacity:  100 fasteners
· Operating pressure:  70-110 PSI (4.8-7.5 bar)
· Max pressure:  120 PSI
· Air consumption:  0.5 CFM per staple, 30 staples/minute @ 80 PSI

Note:  Take the actual rate at which the tool will run to determine the amount of air
required.  For instance, if your fastener usage averages 15 fasteners per minute, you need
50% of the tool's CFM requirement of free air to run the tool at 30 fasteners per minute.

OPERATION

Caution: This flooring stapler was designed for use in installing unfinished hardwood

flooring.  It can be used to install pre-finished flooring, however caution must
be used to ensure that the finish is not damaged by the tool.  It is recommended
that the tool be tested on a sample section to be certain that the technique
of use does not leave marks on the finish.  This procedure should be followed
before each job due to variations in flooring and tool condition.

Air supply and connections

Fittings:

Install a male plug on the tool which is free flowing and will release air
pressure from the tool when disconnected from the supply source.

Hoses:

Air hoses should have a minimum of 150 PSI working pressure rating, or 1.5
times the maximum pressure that could be produced in the air system.  The
supply hose should contain a fitting that will provide quick disconnecting
from the male plug on the tool.

Supply source:

Use only clean, regulated compressed air as a power source for this
tool.  Do NOT use oxygen, combustible gas, or bottled gas as a power

                 source for this tool, as tool may explode.

Regulator:                A pressure regulator with an operating pressure of 0 - 125 PSI is
 

                 required to control the operating pressure for safe operation of this tool.

Operating Pressure:   Do not exceed the recommended maximum operating pressure 

of 120 PSI as tool wear will be greatly increased.  The air supply
must be capable of maintaining the operating pressure of the tool.
Pressure drops in the air supply can reduce the tool's driving power.
Desired operating pressure is between 70 to 100 PSI.
