Toro Mower Safety
The following list contains safety information specific to
Toro products or other safety information that you must
know that is not included in the ANSI standards.
This product is capable of amputating hands and feet and
throwing objects. Always follow all safety instructions to
avoid serious injury or death.
Use of this product for purposes other than its intended use
could prove dangerous to user and bystanders.
Operation
•Know how to stop the machine and engine quickly.
•Always wear substantial shoes. Do not operate the
machine while wearing sandals, tennis shoes, or
sneakers.
•Wearing safety shoes and long pants is advisable and
required by some local ordinances and insurance
regulations.
•Fill fuel tank until level is 1 in. (25 mm) below the
bottom of the filler neck. Do not overfill.
•Check the safety interlock switches daily for proper
operation. If a switch should fail, replace the switch
before operating the machine. After every two years,
replace all three interlock switches in the safety system,
regardless if they are working properly or not.
•Pay attention when using the machine. To prevent loss
of control:
– Do not drive close to sand traps, ditches, creeks, or
other hazards.
– Avoid sudden stops and starts.
– Watch for traffic when near or crossing roads.
Always yield the right-of-way.
– Lower the cutting unit when going down slopes.
•The grass deflector must always be installed and in the
lowest position on the side discharge cutting unit. Never
operate the mower without the deflector or entire grass
collector.
•If the cutting unit discharge area ever plugs, shut the
engine off before removing the obstruction.
•Cut grass slopes carefully. Do not start, stop, or turn
suddenly.
•Do not touch the engine or muffler while the engine is
running or soon after it has stopped because these areas
could be hot enough to cause burns.
Maintenance and Storage
•Check the blade mounting bolts frequently to be sure
that they are tightened to specification.
•Make sure that all hydraulic line connectors are tight
and all hydraulic hoses and lines are in good condition
before applying pressure to the system.
•Keep your body and hands away from pin hole leaks or
nozzles that eject hydraulic fluid under high pressure.
Use paper or cardboard, not your hands, to search for
leaks. Hydraulic fluid escaping under pressure can have
sufficient force to penetrate the skin and cause serious
injury.
•Before disconnecting or performing any work on the
hydraulic system, all pressure in the system must be
relieved by stopping the engine and lowering the cutting
units to the ground.
•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.
•Do not overspeed the engine by changing governor
settings. To ensure safety and accuracy, have an
Authorized Toro Distributor check the maximum engine
speed with a tachometer.

5
•The engine must be shut off before checking the oil or
adding oil to the crankcase.
•Make sure that the mower fuel tank is empty if the
machine is to be stored in excess of 30 days. Do not
store the mower near any open flame or where gasoline
fumes may be ignited by a spark.
•Perform only those maintenance instructions described
in this manual. 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.
