standard 120V household outlet. 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, at the end
of the season, after any other extended
periods of non-use, and as needed.
NOTE: If you frequently stop and restart
the mower during each cut throughout
the season (for instance when bagging),
more frequent charging may be
necessary.
3. After charging, disconnect charger
plug from outlet first, then disconnect
charger lead from battery and reattach
cover seal.
IMPORTANT: Do not remove the battery
pack from the electric starter housing for
any reason other than replacement.
IMPORTANT: Always plug charger lead
into battery pack lead first, and then
insert battery charger plug into 120V
standard household outlet. Follow this
order of action every time you charge
the battery.

Off-Season Storage
Mower
The following steps should be taken to prepare
your lawn mower for storage.
• Clean and lubricate mower thoroughly
as described in Lubrication section on
page 12.
• Apply a coat of chassis grease to
mower’s cutting blade to prevent
rusting.
• Refer to Engine Operator’s Manual for
correct engine storage instructions.
• Do not use a pressure washer to clean
your unit.
• 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. For optimal
battery life, charge the battery once per
month while in storage.
• Remove electric starter push key (if
equipped) and keep in a safe place out
of the reach of children.
Briggs & Stratton Battery Pack and
Charger (If Equipped)
• When not in use, disconnect charger
and store in a cool, dry area. Wet, damp
areas can cause corrosion of terminals
and electrical contacts. If stored for
long periods in high temperatures (120
degrees F), permanent damage to the
battery pack can result. Check electrical
terminals and contacts on battery packs
and charger. Wipe with clean cloth or
blow clean with compressed air.
• After storage, a normal charge may be
required. To check available charge,
press the battery fuel gauge button and
charge if required. See the Battery Fuel
Gauge section.
Briggs & Stratton Lithium Ion Battery
Pack Disposal (If Equipped)
WARNING: Battery chemicals
are toxic and corrosive. Fire or
explosion can cause severe burns
or death.
• Never burn or incinerate discarded or
used battery packs as they may explode.
Toxic fumes and materials are created
when battery packs are burned.
• Do not use a battery that has been
crushed, dropped, or damaged.
• Used and discarded battery packs will
likely still carry a small electrical charge
and should be handled with care. Always
dispose of discarded or used battery
packs according to federal, state and
local regulations.
