This is the hazard alert symbol:
ƽ When you see
this symbol, be aware that personal injury or property
damage is possible. The hazard is explained in the
text following the symbol. Read the information
carefully before proceeding.
The following is an explanation of the three
different types of hazards:
ƽ DANGER
Severe personal injury or death
will occur if hazard is ignored.
ƽ WARNING
Severe personal injury or death
can occur if hazard is ignored.
ƽ CAUTION
Minor injury or property damage
can occur if hazard is ignored.
GENERAL INFORMATION
This pump is designed to be used for the purpose of
pumping air. The pump should not be used for the
pumping of fluids, particles, solids or any combus-
tible substances likely to cause explosions.
ƽ DANGER
Do not pump flammable or explosive
gases or operate the unit in an atmo-
sphere containing them.
ƽ CAUTION
The pump is designed for pumping air.
Do not allow corrosive gases or
particulate material to enter the pump.
Water, oil-based contaminants, or
other liquids must be filtered out.
ƽ CAUTION
Normal ambient temperature should
not exceed 40
0 C (104 0 F). For
operation at higher temperatures,
consult the factory.
ƽ WARNING Exhaust air temperature can be-
come very hot. Keep away from air
stream.
Performance is reduced by low atmospheric pressure found
at high altitudes. Consult a Gast distributor for details.
Never lubricate this oil-less pump. Most components are
made of aluminum and the valves are stainless steel.
Pressure Gauge
The pressure gauge shows
the output pressure.
Pressure Regulator
Turn the regulator screw clockwise
to increase pressure (up to approxi-
mately 100 PSI max. with the screw
turned fully to the end stop).
Vacuum Gaug e
The vacuum gauge shows
the inlet vacuum.
Vacuum Regulator
Turn the regulator screw clockwise
to increase vacuum (up to approxi-
mately 25” Hg max. with the screw
turned fully to the end stop).
Note: Maximum pressure and vacuum
cannot be produced at the same time.
