a) Make sure the battery has a full charge. See Section 4.1.20 for charging
instructions.
b) Be sure the throttle control is midway between the “SLOW” and “FAST”
positions.
c) Make sure there is fuel in the fuel tank and that the fuel valve is open.
d) Make sure the parking brake is set and motion control levers are moved out
(neutral lock position).
e) Check that the PTO is disengaged.
f) Check for loose or faulty wiring connections.
g) Check for corrosion at all wiring connections. Even minor corrosion may
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 or
adjustments procedures (such as valves, governor, etc.). Have this work done
by your
Engine Service Dealer.
