MAINTENANCE MANUAL
Shut engine down.
NOTE: On switching off the engine switch off ignition and withdraw the
ignition key.
Inspect rotary seal for leakage.
NOTE: Due to the design of the rotary seal, the manufacturer tolerates
a certain amount of leakage. If the leakage is in excess of the
limit rotary seal must be renewed.
Tolerated leakage:
For this check the engine must be operated until all temperatures have stabi-
lized for a period of 5 minutes. At that point shut down engine and ensure the
ignition is switched off and engine secured against unintentional operation.
Coolant must not drip through leakage bore, located at the base of the ignition
housing, for a period of 1 minute after the engine has been stopped.
In case this leakage test can not be passed, the rotary seal must be renewed.
Risk of severe burns and scalds!
