GAS / HYDRAULIC POWERED AIRLESS
SPRAY PUMPS.
Gas / Hydraulic powered airless spray equipment is an
industrial paint sprayer which uses a gas engine to drive a
hydraulic pump which in turns produces hydraulic pres-
sure. This pump delivers pressure fluid to a hydraulic mo-
tor which drives a high pressure airless piston pump. All
of these components make this unit a heavy duty portable
airless sprayer which is capable of high volume and high
production able to pump and spray light to very high vis-
cous materials. Airless spray is fast, economical and
needs no atomizing air.
Airless spray systems use a high pressure pump
to supply fluid to the spray tip, where it is atomized
by the pressure and sprayed onto a desired surface.
Control of the atomizing pressure is done by regulating
the hydraulic fluid pressure in the hydraulic pump.
The spray is controlled by triggering a hand gun,
or activating the controls of an automated system.
The spray pattern and flow rate is controlled by
choosing the spray tip best suited to your needs.
GENERAL SAFETY WARNING
•
High pressure spray can cause serious injury.
•
Because of the high pressure and velocity of the fluid
being atomized, paint, solvent or other fluids could
penetrate through your skin, into your body or eyes.
•
Never point the spray gun at yourself or anyone else.
•
Never put your hands, fingers or any part of the
body over the spray tip/nozzle.
•
Even after you shut off the pump, there is still high
pressure in the system, You must always follow the
“PRESSURE RELIEF PROCEDURE”
before ser-
vicing, or removal of the spray tip/nozzle.
SAFETY WARNING!
•
Use of this high-pressure equipment could result in serious injury and is for
professional use only!
•
You must operate this equipment only after the instruction manual is clearly understood.
•
Workman and assistant must always wear protective eyewear, gloves, clothing,
and respirators as recommended by the material manufacturer.
SPRAY GUN SAFETY WARNING
•
Never
point the gun at yourself or anyone
else: This can result in serious injury.
•
Safety latch:
Engage trigger safety latch in
the closed or “LOCK” Position see FIG 1,
whenever you stop spraying, even for a mo-
ment. Failure to engage trigger safety latch
can result in serious injury.
•
Trigger safety guard:
This prevents the
gun from triggering accidentally when it is
dropped or bumped. You must not operate
without the trigger safety guard.
•
When
cleaning or changing the tips use ex-
treme caution and follow the “
PRESSURE
RELIEF PROCEDURE”
then remove the
spray tip.
•
Aim
the spray gun into a grounded metal
pail using the lowest pressure possible,
then trigger the spray gun.
•
If
the fluid sprayed is not diffused into a
irregular stream, replace the diffuser at once.
•
If
the spray tip clogs while spraying, engage
trigger safety latch in “SAFE” position
immediately.
•
Never
wipe off around the spray tip until
pressure is fully relieved and the trigger
safety latch in “SAFE” position.
