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 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.
•Handle fuel carefully. Wipe up any spills.
•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.
•Using the machine demands attention. To prevent loss
of control:
– Do not drive close to sand traps, ditches, creeks, or
other hazards.
– Reduce speed when making sharp turns. Avoid
sudden stops and starts.
– Watch out for traffic when near or crossing roads.
Always yield the right-of-way.
– Apply the service brakes when going downhill to
keep forward speed slow and to maintain control of
the machine.
•Raise the cutting unit when driving from one work
area to another.
•Do not touch the engine, muffler, or exhaust pipe
while the engine is running or soon after it has stopped
because these areas could be hot enough to cause
burns.
•If a cutting unit strikes a solid object or vibrates
abnormally, stop immediately, turn the engine off, wait
for all motion to stop, and inspect the machine for
damage. A damaged blade must be replaced before
operation is continued.
•Traverse slopes carefully. Do not start or stop suddenly
when traveling uphill or downhill.
•The operator must be skilled and trained in how to
drive on hillsides. Failure to use caution on slopes or
hills may cause loss of control and cause the vehicle to
tip or roll, possibly resulting in personal injury or
death.
•If the engine stalls or loses headway and cannot make
it to the top of a slope, do not turn the machine around.
Always back slowly, straight down the slope.

SAFETY INSTRUCTIONS
•When a person or pet appears unexpectedly in or near
the mowing area, stop mowing. Careless operation,
combined with terrain angles, ricochets, or improperly
positioned guards can lead to thrown object injuries.
Do not resume mowing until the area is cleared.
•Whenever the machine is left unattended, make sure
the cutting unit is disengaged, the key is removed from
the ignition switch, and the parking brake is set.
Maintenance and Storage
•Make sure 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 and attachments to the ground.
•Check all fuel lines for tightness and wear on a regular
basis. Tighten or repair them as needed.
•Periodically inspect the roll bar and roll bar mounting.
Repair, as necessary. Do not weld, cut, drill, or modify
roll bar in any manner.
•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, especially the
screen at the side of the engine. 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.
•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.
