When storing the machine for long periods, follow
these procedures:
• Wash and clean each section of the machine
and store inside. If the machine is to be stored
outside, select a flat location where the machine
will not be exposed to water, flooding or other
elements.
• Fill the fuel tank with fuel, lubricate all grease
fittings and change the engine oil.
• Disconnect the positive (+) and negative (-)
battery terminals and cover the battery or
remove the battery from the machine.
• Fill the engine cooling system with coolant fluid
and check or adjust the mixture as necessary to
prevent freezing.
• Cover the machine. In addition, cover the
electric motor and hydraulic pump of the electric
unit with a plastic sheet. Use a dehumidifying
agent in the covered sheet to keep the machine
free of moisture.
During Storage
WARNING! Exhaust Hazard. Operate the
machine in a well-ventilated area.
Operate the machine once a month (5 minutes
minimum) during storage to prevent corrosion
buildup and to charge the battery.
Quarterly insulation resistance tests of electric
motor wiring are required during long-term
storage. Contact us or our sales service agency to
request inspection procedures and service
information.
