 Warning:
1. Never point the spray gun at people or animals.
2. The pump will produce high temperatures when operating.
3. Keep hands and clothing clear of the belts and pulleys when operating the
pump.
 Before Use/Start Up:
1. Check every fastener, including all hose clamps, to make sure that the spray-
er and the engine are installed firmly to the frame.
2. Align the pump and engine pulleys in a straight line and tighten the belts ap-
propriately.
3. Check engine (see engine manual) and pump oil (non-detergent). Fill as
needed to recommended levels. DO NOT OVER FILL!
4. Check engine fuel. Fill as needed, with engine manufacture recommended
fuel.
5. Attached the spray gun to the spray hose and tighten all clamps.
6. Set the pump pressure regulator to “Pressure Release” and make sure the
pressure regulator knob is set to “Start”.
7. Check the on/off switches of engine.
8. Start engine.
9. Set the pump pressure regulator to “Spraying”.
10.Adjust the pressure by turning the adjustable pressure regulator valve clock-
wise.
 During Use:
1. Make sure the pump has sufficient liquid supply to allow the pump to reach
its working pressure.
2. To prolong the life of the pump, always operate the machine within its speci-
fied pressure limits. Adjust the pressure by turning the adjustable regulator
knob clockwise.
3. In order to avoid any damage to the packing and the pump, shut off the en-
gine or motor when temporarily stopping the unit for more than 5 minutes.
4. Avoid running the pump without liquid.

 After Each Use:
1. Set the pressure regulator switch to “Pressure Release”, and run the pump
with clean water to prolong the life of the pump.
2. Set the pressure regulating knob to “START” when the pump is not in use.
 Maintenance:
1. Change the oil in the pump after the first 10-15 hours of use. After this,
change the oil in the pump after every 70 hours of use. NOTE: Always make
sure the oil is clean and visible thru the oil sight gauge Ref#11A before
operating.
2. Change or replace components, based on the symptoms as listed in the
trouble shooting section.
 How to Change Oil:
1. Remove Ref # 12A Drain Plug. Allow the oil and any sludge to drain from
the crankcase into an EPA approved collection device.
2. Replace Ref # 12A Drain Plug once the crankcase has been drained.
3. Remove Ref # 7A Oil Fill Cap and fill crankcase with NON Detergent oil (see
chart) until the oil level reaches the center mark in Ref # 11A Oil Window.
