Operation
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.
Before Using
See Fig. 2. 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.
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.
Open the bleed–type air valve (M), hold the spray
valve trigger (T) open and slowly open the pump air
bleed valve (H) until the pump is running slowly. After
solution is coming from the spray nozzle, open the
pump air bleed valve all the way and adjust the air line
lubricator (G) to deliver about 1 drop per minute. Refer
to the separate lubricator instruction manual.
Release the spray valve trigger and let the pump run.
NOTE: Protect surfaces that might be damaged by the
cleaning solution and rinse off before the solution
dries. For removing stubborn dirt, use a strong, heated
solution.
Useful Hints
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 8.
Hold the spray nozzle about 2 feet (0.6 m) from the
surface you are cleaning and mist-wet it completely.
Let it soak briefly, then use the spray to “chisel” the dirt
off. Keep the nozzle at an angle, about 6 in. (150 mm)
from the surface. If some dirt remains, wet the surface
again. Let the object soak a little longer, then hold the
nozzle as close as possible and spray to blast the dirt
off.
After the dirt is removed, through rinse off the remain-
ing solution with clear, cold water. When you are done
cleaning, close the pump air bleed valve and relieve
the pressure.
Shutdown and Care of Unit
CAUTION
To reduce the risk of damaging your pump. never
allow the pump to run dry of fluid. Keep liquid in the
container to prevent the pump from running away.
WARNING
To reduce the risk of serious injury whenever you
are instructed to relieve pressure, always follow the
Pressure Relief Procedure on page 8.
When shutting down for the day or weekend, shut off
both the bleed–type air valve and pump air bleed
valve. Relieve the pressure. Rinse off any solution
remaining on equipment with clear, cold water. Shut off
the water supply valve and relieve the water pressure.
After shutdown, check the air line lubricator (G) often
and keep it filled with oil. Also check the pump packing
nut regularly and keep it just tight enough to stop
leakage, but no tighter. Use a 1/4 in. diameter rod to
tighten.
