Important
Refer to your engine operator's manual for additional maintenance procedures.
Note: After 50 hours and then every 100 hours thereafter (that is at 150, 250, 350, etc.) the screen displays CHG OIL to
remind you to change the engine oil. After every 100 hours, the screen displays SVC to remind you to perform the other
maintenance procedures based on a 100, 200, or 400 hour schedule. These reminders come on starting three hours prior to
the service interval time and flash at regular intervals for six hours.
If you leave the key in the ignition switch, someone could accidently start the engine and
seriously injure you or other bystanders.
Remove the key from the ignition and disconnect the wire from the spark plug before you do
any maintenance. Set the wire aside so that it does not accidentally contact the spark plug.
