Connecting Hose or Pipe to the Suction Inlet
Note: Keep all hoses short and as straight as possible, failure to do so may decrease the pressure pumps performance.
Note: It is recommended that a filter (30) and check valve (not included) is installed at the end of the suction hose or pipe.
In order to prevent long priming periods and unnecessary damage to the pump as a result of stones and solid
foreign materials entering.
Note: Reinforced or ridge suction hoses are required on the suction line to prevent the pipe from collapsing due to
pressure from suction.
Caution: All connections require being air tight, failure to do so cause result in an air leak which can prevent the
pump from priming. It is recommended that a thread sealant (not included) and/or Teflon tape (not included) is
used on threads to ensure a water tight seal and prevent any leakage during assembly.
1. Assemble the 40mm (11/2") hose clamp (28) and filter (30) strainer to the intake
side of the suction hose (Fig. 2).
2. Tighten the 40mm (11/2") hose clamp (28) tightly ensuring it clamps the hose
against the filter (30) strainer (Fig. 2)
3. Assemble the inlet adaptor (a) by inserting into the 40mm (11/2") collar (26) in (Fig. 3).
Note: Ensure the 40mm (11/2") o-ring (29) is fitted into the 40mm (11/2") collar (26),
failure to do so may result in an air leak.

Pre Operation Inspections
Environment Conditions
The operation of a four-stroke (unleaded) engine is affected by:
1. Temperature
a. Working in low temperatures could lead to difficult cold starting.
b. Working in very high temperatures could lead to difficult hot starting due to evaporation of the fuel.
c. In any case, the correct oil must be used according to the operating temperatures.
2. Altitude
a. The higher the altitude (above sea level), the lower the pressure and flow rate will be.
b. When there is a considerable increase in altitude, the load on the machine should be reduced and heavy
work load should be avoided.
Fuel inspection
WARNING! Be sure to stop the engine before re-fueling. A good quality fuel is the major issue for engine
reliability of operation.
WARNING! Do not over fill the fuel tank.
WARNING! Do not smoke while re-fueling.
1. Use unleaded petrol with a minimum of Octane 91.
2. Use clean, fresh fuel; purchase fuel in quantities that can be used every 30 days, to prevent gum or foaming
inside the container and/or fuel tank.
3. Do not use fuel which contains methanol.
4. Do not add oil or any kind of fuel additive.
Engine oil inspection
The high pressure pump is shipped without oil. Before starting ensure an oil inspection is conducted.
Always use high quality oils, select their viscosity grade according to the operating temperatures.
Note: It is recommended that SAE-10W-30 (multi viscosity) oils are used at temperatures from 5 to 35ºC and
synthetic oils 5W-30 (multi viscosity) is used for temperatures -5 to 5ºC.
To change or top up the oil in the engine refer to the maintenance section of this instruction manual.
