Preventing Water Hammer
Water hammer occurs when the discharge
flow is suddenly blocked or stopped. Pressur-
ized chemicals trapped inside the pump can
quickly boil and crack or damage the pump
housing. To prevent water hammer:
• Do not close the discharge valve while the
pump is operating.
• Do not allow vehicles to drive over the dis-
charge hose.
• Do not abruptly compress the discharge
hose.
• Do not shut off flow while the engine is run-
ning.
Chemical Pump Shut Down
1. Move throttle lever from fast to slow.
2. Turn engine switch OFF.
3. Move fuel valve lever to OFF position.
4. Allow the engine to cool thoroughly.
After Each Use

priming plug (A) and drain plug (B) from the
pump housing and allow it to drain thoroughly.
