Maintenance and Storage
Safety
•
Before repairing the machine do the following:
– Disengage the drives.
– Engage the parking brake.
– Shut off the engine and remove the key.
– Disconnect the spark-plug wire.
•
Park the machine on a level surface.
•
Clean grass and debris from the cutting unit, drives,
mufflers, and engine to help prevent fires.
•
Clean up oil or fuel spills.
•
Let the engine cool before storing the machine.
•
Do not store the machine or fuel near flames or drain
the fuel indoors.
•
Do not allow untrained personnel to service the machine.
•
Use jack stands to support the machine and/or
components when required.
•
Carefully release pressure from components with stored
energy.
•
Disconnect the battery or remove the spark-plug wire
before making any repairs. Disconnect the negative
terminal first and the positive terminal last. Connect the
positive terminal first and negative last.
•
Use care when checking the blades. Wrap the blade(s)
or wear thickly padded gloves, and use caution when
servicing them. Only replace blades; do not straighten
or weld them.
•
Keep your hands and feet away from moving parts.
If possible, do not make adjustments with the engine
running.
•
Keep all parts in good working condition and all hardware
tightened, especially the blade-attachment bolts. Replace
all worn or damaged decals.
•
Never interfere with the intended function of a safety
device or reduce the protection provided by a safety
device. Check their proper operation regularly.
•
To ensure optimum performance and continued safety
certification of the machine, use only genuine Toro
replacement parts and accessories. Replacement parts
and accessories made by other manufacturers could be
dangerous, and such use could void the product warranty.
•
Check the parking brake operation frequently. Adjust and
service as required.
