Priming the Oil Injection Pump

Before starting engine for the first time, prime the oil injection pump. Priming will re-
move any air that may be in the pump, oil supply hose, or internal passages.

To prevent damage to the fuel pumps, fill the engine fuel system with fuel. Other-
wise the fuel pumps will run without fuel during the priming process.
Prime the oil injection pump as follows:
1. Fill the engine fuel system with fuel. Connect fuel hose and squeeze primer bulb until
it fells firm.
2. Turn the ignition key switch to the "ON" position.
3. Within the first 10 seconds after the key switch has been turned on, move the remote
control handle from neutral into forward gear 3 to 5 times. This will automatically start
the priming process.
