2. Insert the battery charger plug into a standard 120
volt household outlet. See Figure 5-15. Charge battery
for 8 to 10 hours before initial use. Do not charge
longer than 12 hours. The battery should only need
to be charged upon initial setup and after any other
extended periods of non-use.
3. After charging, disconnect charger plug from outlet
first, then disconnect charger lead from battery.
IMPORTANT: Always plug charger lead into battery pack
lead first, and then insert battery charger plug into 120
volt standard household outlet. Follow this order of action
every time you charge the battery.
Replacing Fuse
The electric starter circuit and battery are protected by a
40 ampere fuse. If the fuse burns out, the electric starter
will not operate. If the unit fails to start with the electric
starter, perform the following steps to check the fuse
inside the battery housing:
1. Open the battery cover as described in Replacing
Battery. Refer to Figure 5-13.
2. Remove fuse from socket and inspect as shown in
Figure 5-16. If it is burned out, replace with standard
automotive 40 ampere fuse.
3. Carefully place wiring back into housing, close battery
cover, and fold upper handle back into place.
NOTE: The engine can be started manually if the fuse
burns out.
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.
• Refer to engine manual for correct engine storage
instructions.
• 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.
When storing any type of power equipment in a poorly
ventilated or metal storage shed, care should be taken to
rust-proof the equipment. Using a light oil or silicone, coat
the equipment, especially cables and all moving parts of
your lawn mower before storage.
Battery (If Equipped)
The battery must be stored with a full charge. Extended
storage of a discharged battery will reduce life and
capacity of the battery.
Figure 5-16: When replacing fuse, use a standard automotive
40 Amp fuse.
