4.3.2- Discharge hose
a) Preliminary notes:
Use a commercially available hose, hose connector, and hose
clamp. A short, large-diameter hose is most efficient.
A long or small-diameter hose increases fluid friction and
reduces pump output.
Tighten the hose band securely to prevent the hose from
disconnecting under high pressure
b) Assembly (Fig.7)
1. Insert the coupling into the discharge hose.
2. Use the clamp and tape (not supplied) and tighten firmly.
Then screw the hose coupling to the pump discharge port [12].

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
