Trouble Shooting - Exmark Laser Z Operator's Manual

Federal law states that batteries should not be placed in the garbage. Management and
disposal practices must be within relevant federal, state or local laws.
If a battery is being replaced or if the unit containing the battery is no longer operating and
is being scrapped, take the battery to a local certified recycling center. If no local recycling
is available return the battery to any certified battery reseller.

7. TROUBLE SHOOTING

7.1 MOWER PULLS LEFT OR RIGHT (W/LEVERS FULLY FORWARD).
a) It is common for a machine to pull slightly left or right with levers fully
forward. Move levers forward and compensate as necessary.
b) Check air pressure in tires; 13 psi/drive, 13 psi/pneumatic castors.
c) Check reverse indicator and motion control linkage adjustment. See
section 5.2.13 and 5.2.14.
7.2 MOWER CUTS UNEVENLY.
a) Check air pressure in tires; 13 psi/drive, 13 psi/pneumatic casters. A more
uniform cutting height may be obtained with higher tire pressure on rough
terrain.
A lower tire pressure provides more flotation. Higher pressures in front
casters may cause them to shimmy on hard surfaces.
b) Check deck support chains.
c) Check deck leveling (See Adjustments Section 5.2.2.)
Note: The front of the mower deck will be approximately 1/4" lower than the
back of the mower deck. This is the "rake" of the deck.
d) Check blades tip to tip for straightness (they should be within 3/16" or one
blade width from being in line.)
7.3 ENGINE WILL NOT START.
a) Make sure the battery has a full charge. See section 5.1.3 for charging
instructions.
b) For all units except Kohler 26 HP EFI: Be sure the throttle control is
midway between the "SLOW" and "FAST" positions, and the choke is in the
"ON" position for a cold engine or the "OFF" position for a warm engine.
c) Make sure there is fuel in the fuel tank and that the fuel valve is open.
d) Operator must be in the seat. Be sure the seat switch is properly adjusted.
See Section 5.2.7.
e) Make sure the parking brake is set and motion control levers are moved
out (neutral lock position).
f) Check that the blades are disengaged.
g) Check that the spark plug wires are properly connected.
h) Check for loose or faulty wiring connections.
i) 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.
