PREPARATIONS
1.
Connect the suction hose.
Use a reinforced-wall or wire braided hose to
prevent suction collapse. Since the pump’s
self-priming time is directly proportional
hose length, a short hose is recommended.

2.
Connect the discharge hose.
When using a fabric hose, always use a hose band to prevent the hose from
disconnecting under high pressure.
3.
Check the fuel level.
If level is low, fill to the shoulder of the fuel filter.
Use the mixture fuel prepared by mixing gasoline and exclusive 2-cycle oil at
ratio of
