and nozzle holders may not adequately grip worn hose, causing them to blow off under
pressure. Compressed air and abrasive escaping from a burst hose, or disconnected
coupling or nozzle holder, could cause severe injury.
8.
Always place the device so that the outlet is pointed away from any objects or persons.
Stand clear of the path of exiting abrasive. It may come out at high velocity. Impact
from exiting abrasive could cause severe injury.
9.
Static electricity can be created by the use of this equipment. Do not use within fifty feet
of any explosive, potentially explosive substances, or their vapors as an explosion can
occur.
10.
Do not use this equipment in any area that might be considered hazardous or where
flammable gases or liquids are present. Failure to do so may cause an explosion
resulting in serious injury.
OPERATION
Connect your air supply to the handle of the blast gun with a ¼” NPT fitting (not supplied). Insert one end of the siphon
hose to the siphon port on the blast gun. (On part number 40015 insert the other end of the siphon hose to the pick tube
leaving at least ½” of clearance from the outer tube). (On part number 40017 insert the belled end of the hose to the
opening on the bottom of the siphon bucket).
The Abrasive blast cleaner is designed to operate between 80-110 PSI. Pressures of no more than 70 PSI are
recommended for the etching of glass or plastic and the carving of wood. A minimum 2-3 H.P. compressor is required. At
80 PSI the 1/4" nozzle supplied with the product will require 15 CFM. A smaller nozzle requiring only 7 CFM can be
ordered separately. For maximum operating power, no less than 5/16” I.D. air hose of a maximum 50 feet in length with
no splices or restrictions should be connected to a direct line from the compressor tank to the blast gun.
The speed and quality of the blasting depends upon the size of the air jet and nozzle used, air pressure, type and size of
abrasive, and distance from the work surface. The gun should be held almost directly at the object to be cleaned, but at
enough angle that the abrasive doesn’t rebound at the operator. Abrasive power is increased as you hold the gun closer
to the work.
WARNING!
Disconnecting hose while unit is under pressure could cause serious injury or death. Use
safety lock pins and safety cables in all coupling connections to help prevent hose couplings
from accidental disconnection.
If twist-on type air hose couplings are used, they must be secured by safety lock pins or wires
to prevent accidental disconnection while under pressure. Hose disconnection while under
pressure could cause serious injury.
MAINTENANCE
Replace the nozzle when you notice too much air and abrasive or liquid escaping, or if cleaning speed is reduced. When
the air jet is worn, it will deflect the flow downward and will cut a groove in the nozzle. There are optional ceramic nozzles
and Tungsten Carbine that last longer. If air jet and nozzle are not replaced when worn, the suction head will become
damaged.
The nozzle is easily replaced by loosening the nozzle set screw. The air jet is accessible by removing the suction head.
To obtain maximum power, the I.D. of the air jet must by 1/2 the I.D. of the nozzle. When re-assembling the blast gun,
