PRIMING THE OIL INJECTION PUMP
Before starting engine for the first time, prime the oil injection
pump. Priming will remove any air that may be in the pump, oil
supply hose, or internal passages.
a
IMPORTANT: Fill the engine fuel system with fuel before priming
the oil injection pump. Otherwise, the fuel pump will run without
fuel during the priming process and may be damaged.
Prime the oil injection pump as follows:
1. Fill the engine fuel tank with fuel.
NOTE: Use the primer bulb located in the fuel hose to the
engine to draw fuel from the tank to fill the engine fuel system.
2. Position the fuel hose primer bulb so that the arrow on the
side of the bulb is pointing up. Squeeze the fuel hose primer
bulb until it feels firm.
