• The operator shall turn on flashing warning
lights, if provided, whenever traveling on a
public road, except where such use is prohibited
by law.
Maintenance and Storage
• Disengage drives, lower the cutting units, move
the traction pedal to neutral, set the parking
brake, stop the engine and remove the key and
disconnect the spark plug wire. Wait for all
movement to stop before adjusting, cleaning or
repairing.
• Clean grass and debris from the cutting units,
drives, mufflers, and engine to help prevent fires.
Clean up oil or fuel spillage.
• Let the engine cool before storing and do not
store it near flame.
• Shut off fuel while storing or transporting. Do
not store fuel near flames or drain indoors.
• Park the machine on level ground. Never let
untrained personnel service the machine.
• Use jack stands to support components when
needed.
• 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 last.
Reconnect positive first and negative last.
• Use care when checking blades. Wrap the blades
or wear gloves, and use caution when servicing
them. Only replace blades. Never straighten or
weld them.
• Keep your hands and feet away from moving
parts. If possible, do not make adjustments with
the engine running.
• Charge batteries in an open, well-ventilated area,
away from spark and flames. Unplug the charger
before connecting or disconnecting it from the
battery. Wear protective clothing and use
insulated tools.
• Keep all parts in good working condition and all
hardware tightened. Replace all worn or damaged
decals.
Toro Mower Safety
The following list contains safety information specific
to Toro products or other safety information that you
must know.
This product can amputate hands and feet and throw
objects. Always follow all safety instructions to avoid
5

serious injury or death.
Using this product for purposes other than its intended
use could be dangerous to the user and bystanders.
Operation
• 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 the fuel tank until the 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 of
whether or not they are working properly.
• The grass deflector(s) must always be installed
and in the lowest position on the cutting unit.
• Pay attention when using the machine. To
prevent loss of control:
– Drive slowly.
– Do not drive close to sand traps, ditches,
creeks, or other hazards.
– Reduce speed when making sharp turns.
Avoid sudden stops and starts.
– Lower the cutting unit when going down
slopes.
• Do not touch the engine, radiator, or muffler
while the engine is running or soon after it has
stopped because these areas might burn you.
• If a cutting blade strikes a solid object or vibrates
abnormally, disengage the power take off, move
the throttle to Slow, set the parking brake, stop
the engine, and remove the ignition key. Wait for
all motion to stop, and inspect the machine for
damage. Repair or replace any damaged parts
before operating. Ensure that the cutting blades
are in good condition and the blade bolts are
torqued to proper specifications (see the cutting
deck operator’s manual).
• Check carefully for overhead clearances such as
branches, doorways, and electrical wires before
driving under any objects. Do not contact the
objects.
• Make sure that the set belt can be removed
quickly if the machine is driven or rolls into a
pond or lake.
• If the engine stalls or the machine loses headway
and cannot get to the top of a slope, do not turn
the machine around. Always back slowly straight
down the slope.
• If the cutting unit discharge area ever plugs,
disengage the power take off and shut the engine
off before removing the obstruction.
• When operating a 4-wheel drive machine or any
machine on slopes, by banks, or drop offs,
always have the roll-over protection system
installed.
• When operating the machine with the roll-over
protection system, always use the seat belt and
make sure that the seat pivot retaining pin is
installed.
Maintenance and Storage
• Before servicing or making adjustments, stop the
engine and remove the ignition key.
• Ensure that the entire machine is properly
maintained and in good operating condition.
Frequently check all nuts, bolts, and screws.
Check all cutting unit blade bolts frequently to
ensure that they are torqued to proper
specifications (see the cutting deck operator’s
manual).
• Make sure all hydraulic line connectors are tight
and all hydraulic hoses and lines are in good
6

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.
• If the engine must be running to perform a
maintenance adjustment, keep hands, feet,
clothing, and all body parts away from the
cutting units, attachments, power take off shaft,
and any moving parts.
• 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.
Maximum governed engine speed with no load
should be 3200–3250 RPM.
• The engine must be shut off before checking the
oil or adding oil.
• Periodically inspect the roll bar and roll bar
mounting.
Replace, if necessary. Do not modify roll over
protection frames or structures because they are
specifically designed, sized, located, and tested
for injury reduction. If a rollover occurs, a
modified roll-over protection system will not
provide adequate protection.
• If major repairs are ever needed or if assistance is
desired, contact an authorized Toro distributor.
• For 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.
