to make sure that the sprayer and the engine are
installed firmly to the frame.
2. Align the pump and engine pulleys in
a straight line and tighten the belts
appropriately.
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”.

• 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 specified 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 engine or motor when
temporarily stopping the unit for more than 5
minutes.
4. Avoid running the pump without liquid.
• After Each Use:
1. Before adding chemical, set the pressure regula-
tor switch to “Pressure Release”, and run the
pump with clean water to prevent build-up.
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: Al-
ways 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.
4. Once filled, replaced Ref # 7A Oil Fill Cap.
