4.2 PRIMING WATER
WARNING!
Do not operate without priming. Doing so will overheat the
engine and result in damage to the system. Ensure that the
priming water does not contain debris.
Make sure to prime the pump with water prior to operating it. Priming creates a
vacuum that helps to start the flow of water.
1.
Unscrew the primer cap and insert the neck of the water container into the
opening. Gradually fill until the reservoir is full.
2.
Tighten the cap back on.
3.
In case of dry operation (running the pump without priming), stop the
engine immediately and allow it to cool before following the priming
procedure.
