Maintenance and Service

Safety: Safety Instructions
•
Before servicing or making any adjustments to the machine, lower the cutting
units, 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.
•
Wear gloves and use caution when checking or servicing the cutting units.
•
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 system
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 units completely, and then shutting off the engine.
•
Use eye protection when working on the hydraulic system and its
components.
•
To reduce potential fire hazards, keep the engine area free of excessive
grease, grass, leaves, and dirt. Never wash a warm engine or electrical
connections with water.
•
Check all fuel lines for tightness and wear on a regular basis. Tighten or
repair fuel lines as needed.
•
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 units and other moving parts. Keep bystanders away.
•
Do not over-speed 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 batteries 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
the battery.
•
Battery gases can explode. Keep cigarettes, sparks, and flames away from
the battery.
•
If major repairs are necessary, contact your Authorized Toro Distributor.
•
At the time of manufacture, the machine conformed to the safety standards
for riding mowers. To ensure the optimum performance and continued
safety certification of the machine, use genuine Toro replacement parts and
accessories. The replacement parts and accessories of other manufacturers
can result in non-conformance with the safety standards and can void the
warranty.
•
When changing the attachments, tires, or performing other service; refer
to Jacking Instructions (page 1–7).
