• Do not mow near drop-offs, ditches, or
embankments. The machine could suddenly turn
over if a wheel goes over the edge of a cliff or ditch,
or if an edge caves in.
• Do not mow on wet grass. Reduced traction could
cause sliding.
• Use extra care with other attachments. These can
change the stability of the machine.
• Turn off the blades when not mowing.
Maintenance and Storage
• Do not touch equipment or attachment parts which
may be hot from operation. Allow to cool before
attempting to maintain, adjust, or service.
• Never store the machine or fuel container inside
where there is an open flame, such as near a water
heater or furnace.
• Keep nuts and bolts tight, especially the blade
attachment bolts. Keep equipment in good
condition.
• If the engine must be running to perform a
maintenance adjustment, keep hands, feet, clothing,
and any parts of the body away from the cutting
units, attachments, and any moving parts. Keep
everyone away.
• Check brake operation frequently. Adjust and service
as required.
• Battery acid is poisonous and can cause burns. Avoid
contact with skin, eyes, and clothing. Protect your
face, eyes, and clothing when working with a battery.
• Battery gases can explode. Keep cigarettes, sparks,
and flames away from the battery.
• The engine must be shut off before checking the oil
or adding oil to the crankcase.
• If major repairs are ever needed or if assistance is
desired, contact an Authorized Toro Distributor.
• To make sure of 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.
