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.
