Maintenance Safety
•
Before you leave the operator’s position, do the
following:
– Park the machine on a level surface.
– Disengage the power takeoff and lower the
attachments.
– Engage the parking brake.
– Shut off the engine and remove the key (if
equipped).
– Wait for all movement to stop.
•
Allow machine components to cool before
performing maintenance.
•
If the cutting units are in the transport position, use
the positive mechanical lock (if equipped) before
you leave the machine unattended.
•
If possible, do not perform maintenance while the
engine is running. Keep away from moving parts.
•
Support the machine with jack stands whenever
you work under the machine.
•
Carefully release pressure from components with
stored energy.
•
Keep all parts of the machine in good working
condition and all hardware tightened, especially
blade-attachment hardware.
•
Replace all worn or damaged decals.
•
To ensure safe, optimal performance of the
machine, use only genuine Toro replacement
parts. Replacement parts made by other
manufacturers could be dangerous, and such use
could void the product warranty.
