NOTE
Use the priming pump to make sure the fuel filter, fuel lines, manifolds, and injectors
are full of fuel before attempting to start the engine. During cold weather add starting
fluid at the same time the Hydrostarter motor lever is moved. Do not wait to add starting
fluid after the engine is turning over.
Set the engine controls for starting-throttle at least half open.
Push the Hydrostarter control lever, to simultaneously engage the starter pinion with the flywheel ring gear and
to open the control valve. Close the valve as soon as the engine starts, to conserve the accumulator pressure and to
avoid excessive over-running of the starter drive clutch assembly.
