An engine equipped with a hydrostarter may be started as follows:
Raise the hydrostarter accumulator pressure with the hand pump until the gage reads as indicated in Table 1.
Set the engine controls for starting with the throttle at least half open.
NOTE: During cold weather add starting fluid at the same time the hydrostarter motor lever is moved. Do
not wait to add the fluid after the engine is turning over.
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.
Observe the oil pressure gage immediately after starting the engine. If there is no pressure indicated within 10 to 15
seconds, stop the engine and check the lubricating oil system. The minimum oil pressure should be at least 18 psi (124
kPa) at 1200 rpm. The oil pressure at normal operating speed should be 40-60 psi (276-414 kPa).
Run the engine at part throttle and no-load for approximately five minutes, allowing it to warm-up before applying a load.
If the unit is operating in a closed room, start the room ventilating fan or open the windows, as weather conditions permit,
so ample air is available for the engine.
Do not engage the clutch at engine speeds over 1000 rpm.
While the engine is running at operating temperature, check for coolant, fuel or lubricating oil leaks. Tighten the line
connections where necessary to stop leaks.
Normal engine coolant temperature is 160-185° F (71- 85° C).
If the engine crankcase was refilled, stop the engine after normal operating temperature has been reached, allow the oil
to drain back into the crankcase for approximately twenty minutes and check the oil level. Add oil, if necessary, to bring
it to the proper level on the dipstick.
Use only the heavy duty lubricating oil specified under Lubricating Oil Specifications.
Remove the radiator or heat exchanger tank cap slowly after the engine has reached normal operating temperature and
check the engine coolant level. The coolant level should be near the top of the opening. If necessary, add 'clean soft
water or a high boiling point type antifreeze (refer to Engine Coolant).
Check the marine gear oil pressure. The operating oil pressure range for the marine gear at operating speed is 120 to
160 psi (827 to 1103 kPa) and minimum oil pressure is 100 psi (689 kPa) at idle speed (600 rpm).
Make a visual inspection of the turbocharger for leaks and excessive vibration. Stop the engine immediately if there is
an unusual noise in the turbocharger.
