Maintenance and Troubleshooting
WARNING
Accidental Start-up. Disconnect the negative battery
cable, then the positive battery cable when working
on unit. Failure to do so could result in death
or serious injury.
WARNING
Environmental Hazard. Always recycle batteries at an
official recycling center in accordance with all local
laws and regulations. Failure to do so could result in
environmental damage, death or serious injury.
Always recycle batteries in accordance with local laws
and regulations. Contact your local solid waste collection
site or recycling facility to obtain information on local
recycling processes. For more information on battery
recycling, visit the Battery Council International website
at: http://batterycouncil.org
Follow the recommendations below for battery's best per-
formance.
• Do not allow battery to discharge completely or
excessively. If unit is not being used, charge bat-
tery every 4–6 weeks. Operate engine for at least
45 minutes to maintain proper battery charge.
•
Store unused batteries in a dry area that does not
freeze.
• Do not charge a fully charged battery. A fully
charged battery on a charger creates heat, which
can damage the battery. A fully charged battery
reads 12–13.2 volts with a voltmeter.
• Do not continue to crank engine when battery
charge is low.
• Battery will not need special attention with the addi-
tion of electric dump system under normal work
conditions. If operating for extended periods with
frequent dumps, leave engine running during idle
periods to maintain proper charge.

Charging Battery

Operate engine for at least 45 minutes to maintain proper
battery charge. Use a trickle charger to recharge if bat-
tery loses charge. Trickle charger should have an output
of 12V at no more than 2 amps.
• At 1 amp, battery may charge for as long as 48
hours.
• At 2 amps, battery may charge for as long as 24
hours.
NOTE: Using recoil starter and running engine will not
recharge a dead or significantly discharged battery.

Connecting Battery to Trickle Charger

1. Detach battery cables from battery.
2. Attach red (+) battery charger cable to red (+) bat-
tery terminal, and black (-) battery charger cable to
black (-) battery terminal.

3. Plug battery charger into outlet.
NOTE: Disconnect battery charger from outlet first, then
disconnect charger cables from battery terminals when
charging is completed. If battery charger cables are left
connected to battery when battery charger is unplugged,
battery will discharge into charger.

End of Season and Storage

Risk of Fire. Verify machine has properly
cooled before installing cover and storing
machine. Hot surfaces could result in fire.
Unit must be stored when not in use for extended periods
of time. Perform the actions below before storage:
• Add stabilizer to fuel tank as needed. Completely
fill tank with fresh, unleaded fuel and add appropri-
ate amount of stabilizer or additive. Run engine for
a short time to circulate additive.
• Change oil to eliminate sludge and acid buildup. In
colder climates, use SAE 5W-30W.
•
Remove spark plug and add 1 oz (29.6 ml) of
engine oil into the cylinder hole. Install spark plug
and pull recoil starter rope until there is strong
resistance to coat the piston and seat the valves to
prevent moisture buildup.
• Clean and replace air filter(s).
•
Clean cylinder head cooling fins, carburetor link-
age, blower housing, rotating screen, and muffler
areas.
• See
grease fittings.
• Verify operator controls are moving freely. Lubri-
cate throttle lever cable, parking brake cable, and
traction control cable with SAE 30 oil if necessary.
See
• Remove battery and store in a cool, dry place.
Charge battery once a month, and before returning
to service.
• Clean exterior of unit to remove all dirt, grease, and
any other foreign material. Touch up painted sur-
faces that have been scratched or chipped to pre-
vent rust.
•
Store unit in a dry, protected place. Cover unit if
stored outdoors.
