Pressure Relief Procedure
TO reduce the risk of serious
bodily injury, including splash-
ing in the eyes or on the skin,
always follow this procedure
whenever you shut off the
pump, when checking or serv-
icing any part of the system,
and when installing, cleaning
or changing any part of the
system.
1. Disconnect the air to the
pump.
2. Point the dispensing valve
away from yourself and
others.
3. Open the dispensing valve
until pressure is relieved.
If you suspect that the dis-
pensing valve or hose is com-
pletely clogged, or that pres-
sure has not been fully relieved
after following the steps above,
VERY SLOWLY loosen the hose
end coupling and relieve pres-
sure gradually, then loosen
completely. Now clear thevalve
or hose.
INSPECTION
INSTRUCTIONS
If overpressurizing of the equipment
is believed to have occurred, contact
the factory authorized warranty and
service center nearest you for inspec-
tion of the pump.
Specialized equipment and knowl-
edge is required for repair of this pump.
Contact the factory authorized warranty
and service center nearest you for
repairs or adjustments other than main-
tenance specified in this manual.
Annual Inspection is recommended
by the factory authorized warranty and
service center nearest you.
Alist of factory authorized warranty
and service centers is available upon
request.
DAMAGED PUMPS
Any pump that appears to be dam-
aged in anyway, is badly worn or operates
abnormally, shall be removed from use
until repairs are made. Contact the
factory authorized warranty and service
center nearest you for repairs.
OPERATION
Flushing
Flush the supply lines and hoses
with compatible solvent and blow dry
with air before connecting them to the
system. This is to purge any contami-
nents such as dirt, moisture or metal
shavings that could damage the pump
or system components
Then flush the pump. The pump was
tested in lightweight oil, which was left
in to protect the pump from corrosion.
Flush outthepump before connecting it
to the system if the oil could contami-
nate the fluid you are pumping.
When flushing the pump
with solvents, to reduce the
risk of injury from splashing or
static sparking, always hold a
metal part of the dispensing
valve firmly to the side of a
grounded metal pail, and use
the lowest possible fluid pres-
sure when flushing.
This pump can develop 600
PSI maximum working pres-
sure, at 200 PSI maximum in-
coming air pressure. Be sure
that all equipment and acces-
sories are rated to withstand
the maximum working pressure
of this pump. DO NOT exceed
the maximum working pressure
of any component or accessory
used in the system.
In acirculating system, the pun
runs continuously and slows down or
speeds up assupply demands, until the
air supply is shut off.
In adirect supply system, with ade-
quate air pressure supplied to the motor,
thepump starts when thegunordispen-
sing valve is opened and stalls against
pressure when it is closed
If the pump accelerates quickly or is
running too fast, stop it immediately.
Check the fluid supply and refill it if
necessary. Prime the pump to remove
allairfrom thesystem, or flush the pump
and relieve pressure.
MAINTENANCE
Always follow the Pressure
Relief Procedure Warning when-
ever you stop spraying and
before checking or repairing
anypartof the system, to reduce
the risk of serious bodily injury.
If you are pumping fluid which dries,
hardens or sets up, flush the system
with acompatible solvent as often as
necessary to prevent abuildup of dried
fluid in the pump or hoses.
Corrosion Protection for
Carbon Steel Pumps
Water, oreven moist air, can
cause your pump to corrode.
To help prevent corrosion,
NEVER leave the pump filled
with water or air. After normal
flushing, flush the pump again
with mineral spirits oroil-based
solvent, relieve pressure, and
leave the mineral spirits in the
pump. Be sure to follow all
steps of the Pressure Relief
Procedure Warning.
