5.2.12 Adjust Throttle Lever Tension (B&S Engines only):
a)
Stop engine and remove spark plug.
b)
Tension in throttle levers can be increased or decreased by adjusting the
tightness of the lever pivot bolt which is located under the console.
6. TROUBLE SHOOTING
6.1 MOWER PULLING LEFT OR RIGHT.
a)
Check idler arm pulleys and drive sheaves for mud and/or grass buildup.
Check for proper scraper position. See 5.2.6.
b)
Check to be sure idler arms pivot freely, if not lubricate idler pivots.
c)
Check for worn drive belts.
NOTE: Wheel drive belts should be replaced as a set. A new belt should
not be mixed with a worn belt.
d)
Check drive linkage adjustment - See 3.11
e)
Check for proper tire pressure in drive tires. Recommended tire pressure
for the drive tires is 12 to 16 psi. Higher pressures may be used in the tire
on the side that it pulls to (up to 28 psi).
Note
:
Different pressures may make mower cut unevenly.
6.2 MOWER CUTS UNEVENLY.
a)
Check the drive tire pressure and tire circumference. See 5.1.10. 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.
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.)
6.3 ENGINE WILL NOT START.
a)
Check that choke is in the “ON” position for a cold engine or in the “OFF”
position for a warm engine. See 4.3.2.
NOTE:
Kawasaki engines may need to be choked even when warm.
b)
Make sure the key switch is in the “ON” position (B&S and 15 & 17 HP
Kawasaki engines only).
c)
Make sure transmission is in “true neutral” position. (See section 3.10c).
d)
Check that the blades are disengaged and the blade switch is depressed.
e)
Check that there is fuel in the tank and that the fuel valve is open.
f)
Check that the spark plug wire(s) are properly connected.
g)
Check for loose or faulty wiring connections. If it is necessary to
disconnect wire connectors,
Do Not
pull on the wires while disconnecting.
h)
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.
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.
