recycling is available return the battery to any certified battery reseller.
6. TROUBLE SHOOTING
6.1 MOWER PULLS LEFT OR RIGHT (W/LEVERS FULLY FORWARD).
a) Refer to Tracking Adjustment Section 4.2.5.
b) Check air pressure in drive tires.
AT101 (Bar Lug) drive tires should be inflated to 9 psi (62 kpa).
Turf Mate drive tires should be inflated to 13 psi (90 kpa).
Semi-pneumatic casters do not require inflation.

6.2 MOWER CUTS UNEVENLY.

a) Check air pressure in drive tires.
AT101 (Bar Lug) drive tires should be inflated to 9 psi (62 kpa).
Turf Mate drive tires should be inflated to 13 psi (90 kpa).
Semi-pneumatic casters do not require inflation.
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 leveling (See Adjustments in Deck Manual).
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.
c) Check the distance from the bottom edge of the deck skirt to the tip of each
blade. Measurement should be consistent between all blade tips.

6.3 ENGINE WILL NOT START.

a) Make sure the battery has a full charge. See section 4.1.3 for charging
instructions.
b) Be sure the throttle control is in the correct position. See section 3.3.2.
c) Make sure there is fuel in the fuel tank.
d) Make sure the parking brake is set and motion control levers in the neutral
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 of
adjustments procedures (such as valves, governor, etc.). Have this work done
by your Engine Service Dealer.
