overheating of the engine.
INITIAL STARTING PROCEDURE
NOTE: For initial start up of a new engine, or for an engine that ran
out of fuel or was drained of fuel, the fuel system should be filled
according to the following procedure.
1. Squeeze the fuel line primer bulb until it feels firm.
2. Turn the ignition key switch to the "ON" position for three
seconds. This operates the electric fuel pump.
3. Turn the ignition key switch back to the "OFF" position, and
squeeze the primer bulb again until it feels firm. Turn the
ignition key switch to the "ON" position again for three
seconds. Continue this procedure until the fuel line primer bulb
stays firm.

Operating Instructions, in the Operation Section.
