Storage
If you wish to store the machine for a long period
of time, perform the steps listed in Preparing the
Machine for Storage ( page 53 ) .
Storage Safety
• Lower the cutting units, engage the parking brake,
shut of f the machine, remove the key , and wait
for all movement to stop before you leave the
operator ’ s position. Allow the machine to cool
before adjusting, servicing, cleaning, or storing it.
• Do not store the machine where there is an open
ame, spark, or pilot light, such as on a water
heater or other appliance.
• Store the machine in a dry location indoors, out of
the reach of children and away from direct sunlight.
Preparing the Machine for
Storage
1. Always shut of f the machine, remove the key ,
wait for all moving parts to stop, and allow the
machine to cool before adjusting, cleaning,
storing, or repairing the machine.
2. Remove accumulations of dirt and old grass
clippings. Sharpen the reels and bedknives, if
necessary; refer to the cutting unit Operator's
Manual . Coat the bedknives and reel blades
with a rust preventive.
3. Raise and support the machine to remove its
weight from the tires.
4. For prolonged storage, follow the battery
storage requirements; refer to Battery Storage
Requirements ( page 53 ) .
Battery Storage
Requirements
Note: Y ou do not need to remove the batteries from
the machine for storage.
Refer to the temperature limits for storage in the
following table:
T emperature Limits for Storage
Storage T emperature Appropriate Storage T ime
45° to 55°C (1 13° to 131°F)
1 week
25° to 45°C (77° to 1 13°F)
3 weeks
-20° to 25°C (-4° to 77°F)
52 weeks
Important: T emperatures outside of these ranges
will damage your batteries.
The temperature that the batteries are stored
at will affect their long-term life. Storage for
long periods of time at extreme temperatures
will reduce the battery life. For temperatures
above 25°C (77°F), only store the machine for the
appropriate amount of time indicated in the table.
• Before you store the machine, charge or discharge
the batteries between 40% to 60% (54.3V to
57.3V).
Note: A 50% charge is optimal to ensure a
maximum battery life. When the batteries are
charged to 100% before storage, the battery life
shortens.
If you anticipate that the machine will be stored
for a longer period of time, charge the batteries
to around 60%.
• For every 6 months of storage, check the
battery-charge level and ensure that it is between
40% to 60%. If the charge is below 40%, charge
the batteries between 40% to 60%.
• Y ou can use a multimeter to check the charge level
when the machine is of f. Refer to the following
table for the amount of voltage that is equal to the
charge level:
V oltage
Charge Level
57.3V
60%
55.4V
50%
54.3V
40%
• After charging the batteries, disconnect the
battery charger from power . Disconnect the
power connector during storage to minimize the
discharging of the batteries.
• If you leave the charger on the machine, it will
shut of f after the batteries are fully charged and
does not turn back on unless the charger is
disconnected and reconnected.
