4.4- Before starting engine
4.4.1- Check that both suction hose and discharge hose are properly assembled.
4.4.2- Before starting engine and before each use, ensure that both fuel tank and oil tank are fully
filled in. Refill if necessary. (See 3.4 and 3.5 for level check and refill instructions)
4.4.3- Priming the pump
The pump chamber should be completely filled before operating.
Note: Do not operate the pump without priming water or the pump will overheat. Operating the
pump dry will destroy the pump seal. If the unit has been operated dry, stop the engine immediately
and allow the pump to cool before adding priming water.
Fill water into the self-priming port [13] to make the suction hose and the water pump full of water.
Proceed as follows:
1. Remove cap
2. Fill in with water
3. Replace cap

IMPORTANT
:
1. A continual idling or operation without water in the pump will lead to its damage.
So before starting the engine, please make sure that the pump has been refilled water.
If the suction hose strainer appears above the water in the course of operation, stop the engine as
soon as possible.
2.
Make sure that the joint of the suction hose is tightened. Otherwise the air leakage will lead to
no suction or have effect on the power of the pump.
3.
Do not install a valve or tap on the discharge hose.
If you proceed with such installation in order to control the water flow, then never turn off the
valve or tap during operation
4.
Water will not be pumped if the discharged hose is obstructed, the sudden great pressure created
inside the pump may damage the pump.
5.
If the pump is installed in a location where the discharge hose is likely to be stepped on or
pressed, please ensure to cover it with suitable protective covering.
6.
Be sure to install the attached filter (strainer) at the head of the suction hose when it is in use.
7.
Set the suction hose filter (strainer) under the water, but never allow it to touch the mud or sand.
8.
Before use, please check whether each part is loosened or there is any petrol dripping in the fuel
tank.
9.
Before starting the engine, make sure that there is no object that can get wet near the pump.
Remind all bystanders around it that the machine will start working
