Priming
Priming the pump prepares the motor for safe operation.
Caution: Do not run the pump dry, this may result damage to the pump.
1. Unscrew the priming cap (1) by turning anti-clockwise. Using a hose, fill the pump
by pouring water into the priming plug hole (Fig. 8).
2. Ensure the pump and suction line are full.
3. Replace the priming cap (1) and ensure it is secure.
4. Fully open any shut off mechanisms (eg: spray nozzle, valves etc.) in the input
and output hose or pipe so that the air can escape without obstruction.
Pre Operation Inspections
Environment Conditions
The operation of a four-stroke diesel 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. 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 avoided.
