Maintenance and Service

Safety: Safety Instructions
•
Before servicing or making any adjustments to the machine, lower the cutting
decks, set the parking brake, shut off the engine, and remove the key from
the key switch.
•
Ensure that the machine is in safe operating condition by keeping all the
nuts, bolts, and screws tight.
•
Do not store the machine or a fuel container inside where there is an open
flame, such as near a water heater or furnace.
•
Ensure that all of the hydraulic line connectors are tight and that all the
hydraulic hoses and lines are in good condition before applying pressure to
the hydraulic system.
•
Keep your body and hands away from pin-hole leaks in the hydraulic lines
that eject hydraulic fluid under high pressure. Use cardboard or paper to find
hydraulic leaks. The hydraulic fluid escaping under pressure can penetrate
the skin and cause injury. If hydraulic fluid is accidentally injected into the
skin, you must have it surgically removed within a few hours by a doctor
familiar with this type of injury. Otherwise, gangrene may result.
•
Before disconnecting or performing any work on the hydraulic system,
release all the pressure in the system by parking the machine on a level
surface, lowering the cutting deck (or implement) completely, and then
shutting off the engine.
•
Use care when checking or servicing the cutting deck. Wear gloves and
use caution when servicing the deck.
•
To reduce potential fire hazards, keep the engine area free of excessive
grease, grass, leaves, and dirt. Clean the protective screen on the machine
frequently.
•
If you must run the engine to perform maintenance or to make an adjustment,
keep your hands, feet, clothing, and other parts of the body away from the
cutting decks and other moving parts. Keep bystanders away.
•
Do not overspeed the engine by changing the engine governor setting.
To ensure safety and accuracy, check the maximum engine speed with a
tachometer.
•
Shut off the engine before checking or adding oil to the engine crankcase.
•
Disconnect the battery before servicing the machine. Disconnect the negative
battery cable and then the positive cable. If battery voltage is necessary for
troubleshooting or test procedures, temporarily connect the battery. Connect
the positive battery cable and then the negative cable.
•
Battery acid is poisonous and can cause burns. Avoid acid 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.
•
When changing the attachments, tires, or performing other service, use
correct blocks, hoists, and jacks to raise and support the machine. Ensure
that the machine is parked on a solid level surface, such as a concrete floor.
Before you lift the machine, remove all the attachments that may interfere
with the safe and correct lift of the machine. Always block the wheels with
chocks. Use appropriate jack stands to support the raised machine. Failing
to properly support the machine with appropriate jack stands can cause the
machine to move or fall and can result in personal injury; refer to
Instructions (page 1–6).
•
If major repairs are necessary, contact your Authorized Toro Distributor.
•
When welding on the machine, disconnect all the battery cables to prevent
damage to the machine electronic equipment. Disconnect the negative
