Initial Engine Start (Electric)
Start an engine equipped with an electric starting motor as follows: Set the speed control lever at part throttle, then bring it
back to the desired no-load speed. In addition, on mechanical governors, make sure the stop lever on the governor cover
is in the run position. Then press the starting motor switch firmly. If the engine fails to start within 30 seconds, release the
starting switch and allow the starting motor to cool a few minutes before trying again. if the engine fails to start after four
attempts, an inspection should be made to determine the cause.
NOTE: To prevent serious damage to the starter, if the engine does not start, do not press the
starting switch again while the starting motor is running.
RUNNING
Oil Pressure
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).
Warm-Up
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.
Clutch
Do not engage the clutch at engine speeds over 1000 rpm.
Inspection
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.
