Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
1.
Lock the Hydra-Clean
®
gun trigger safety.
2.
Close the pump air regulator.
3.
Close the red handled bleed-type master air valve
(required in your system)
4.
Unlock the gun trigger safety and trigger the gun to
relieve pressure.
5.
Lock the gun trigger safety.
6.
Open the pump drain valve, having a container
ready to catch the drainage.
7.
Leave the drain valve open until you are ready to
spray again.
If you suspect that the dispensing valve, extension, or
grease fitting coupler is clogged, or that pressure has
not been fully relieved after following the steps above,
VERY SLOWLY loosen the coupler or hose end
coupling and relieve pressure gradually, then loosen
completely, now clear the clog.
Before Using
Prepare cleaning solution as instructed, observing all
safety precautions. Pre-mix powered cleaners in a
separate bucket of hot water before adding to water in
the supply drum.
. 2. Open the main air supply valve, hold the
spray valve open and slowly open the air petcock until
the pump is running slowly. After solution is coming from
the spray nozzle, open the ball valve (24) all the way
and adjust the air line lubricator (3) to deliver about one
drop per minute. Refer to the separate lubricator
instruction manual.
Release the spray valve trigger and let the pump run.
The pump will charge the accumulator with liquid
pressure, then stall.
NOTE: Protect surfaces that might be damaged by the
cleaning solution and rinse before the solution dries on
both surfaces. You can clean stubborn dirt off better with
a stronger, heated solution.
WARNING
To avoid serious injury, including fluid injection and
splashing in the eyes or on the skin, never point the
gun at yourself or anyone else.
Fluid under high pressure can be injected through the
skin and cause serious injury. To reduce the risk of an
injury from injection, splashing fluid, or moving parts,
follow the Pressure Relief Procedure whenever you:
•
are instructed to relieve the pressure,
•
stop spraying,
•
check or service any of the system equipment,
•
or install or clean the spray nozzles.
WARNING
Take care not to get spray containing cleaning
chemicals into your eyes, ears, or nose. If any spray
does get on your skin or in your eyes, flush
immediately and thoroughly with water. Seek
immediate medical attention.
