cause a faulty connection. Clean connector terminals thoroughly with
electrical contact cleaner, apply dielectric grease and reconnect.
NOTE: When disconnecting electrical connectors DO NOT pull on the
wires to separate the connectors.
NOTE: After carefully checking the above steps, attempt to start the
engine. If it does not start, contact your authorized Exmark service
dealer.
IMPORTANT: It is essential that all operator safety mechanisms be
connected and in proper operating condition prior to mower use.
When a problem occurs, do not overlook the simple causes. For example,
starting problems could be caused by an empty fuel tank. The following table
lists some of the common causes of trouble. Do not attempt to service or
replace major items or any items that call for special timing of adjustments
procedures (such as valves, governor, etc.). Have this work done by
your Engine Service Dealer.
