Off-Season Storage
The following steps should be taken to prepare your lawn mower
for storage.
• Clean and lubricate mower thoroughly as described in the
lubrication instructions.
• We do not recommend the use of a pressure washer or
garden hose to clean your unit.
• Coat mower's cutting blade with chassis grease to prevent
rusting.
• Store mower in a dry, clean area. Do not store next to
corrosive materials, such as fertilizer.
• Wipe the cord to remove any stains or foreign substance
such as oil.
• Store mower fully charged.
IMPORTANT: We strongly recommend the mower be
charged once every two months during storage.
IMPORTANT: Always recharge mower fully. The charger
is a two stage charger. The first stage, equalize, supplies
a higher voltage to the batteries. This helps speed charge
time and balance the charge across the individual batteries.
The second stage, float, supplies a lower voltage. This
prevents the batteries from experiencing overcharging
damage and also "tops off" the battery charge. Depending
on battery condition the equalize stage will complete
in approximately 8 hours. When the equalize stage is
complete the charger's green LED will stop blinking. This
starts the float stage. During the float stage the chargers
green LED will be on continuously. The float stage will
"top off" the batteries in approximately 4-6 hours, again,
depending on the condition of the battery. However, a full
14 hour charge is always recommended.
