7.2MOWER CUTS UNEVENLY.
a)Check the drive tire pressures and tire circumferences. See 5.1.13. A more uniform cutting height may be obtained with higher tire pressure on rough terrain. A lower tire pressure provides more flotation.
b)Check deck support pins. Hairpin clips must be in the same hole position on each support pin. See Section 5.2.1.
c)Check deck support alignment and check mounting brackets to be sure all bolts are tight.
d)Check blades tip to tip for straightness. (They should be within 3/16”, or one blade width from being in line.)
7.3ENGINE WILL NOT START.
a)Make sure battery has a full charge.
b)Check that the throttle control is midway between “slow” and “fast” positions, and choke is in “on” position for a cold engine or “off” position for a warm engine.
c)Make sure the speed control lever is in the “true neutral” position. See Section 5.2.5.
d)Check that the PTO is disengaged.
e)Make sure the "OPC" levers are depressed.
f)Check that there is fuel in the tank and that the fuel valve is open.
g)Check that the spark plug wires are properly connected.
h)Check for loose or faulty wiring connections. If it is necessary to disconnect wire connectors, Do Not pull on the wires.
i)Check for corrosion at all wiring connections. Even minor corrosion may cause a faulty connection. Clean connector terminals thoroughly, apply dielectric grease and reconnect.
IMPORTANT: It is essential that all operator safety mechanisms be connected and in proper operating condition prior to mower use.
NOTE: After carefully checking the above steps, attempt to start the engine. If it does not start, contact your authorized Exmark service dealer.
ENGINE TROUBLESHOOTING
When a problem occurs, do not overlook the simple causes. For example, starting problems could be caused by an empty fuel tank. The following tables list 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 adjustment procedures (such as valves, governor, etc.). Have this work done by your Engine Service Dealer.
