Maintenance and Service

1.Before servicing or making adjustments, lower deck, stop engine, apply parking brake and remove key from the switch.

2.Make sure machine is in safe operating condition by keeping all nuts, bolts and screws tight.

3.Never store the machine or fuel container inside where there is an open flame, such as near a water heat- er or furnace.

4.Make sure all hydraulic line connectors are tight and all hydraulic hoses and lines are in good condition be- fore applying pressure to the system.

5.Keep body and hands away from pin hole leaks in hy- draulic lines that eject high pressure hydraulic fluid. Use cardboard or paper to find hydraulic leaks. Hydraulic fluid escaping under pressure can penetrate skin and cause injury. Fluid accidentally injected into the skin must be surgically removed within a few hours by a doc- tor familiar with this form of injury or gangrene may re- sult.

6.Before disconnecting or performing any work on the hydraulic system, all pressure in system must be re- lieved by stopping engine and lowering cutting deck to the ground.

7.If major repairs are ever needed or assistance is de- sired, contact an Authorized Toro Distributor.

8.To reduce potential fire hazard, keep engine area free of excessive grease, grass, leaves and dirt. Clean protective screen on machine frequently.

9.If engine must be running to perform maintenance or an adjustment, keep hands, feet, clothing and other parts of the body away from cutting deck and other mov- ing parts. Keep bystanders away.

10.Do not overspeed the engine by changing governor setting. To assure safety and accuracy, check maximum engine speed.

11.Shut engine off before checking or adding oil to the crankcase.

12.Disconnect battery before servicing the machine. Disconnect negative cable first and positive cable last. If battery voltage is required for troubleshooting or test procedures, temporarily connect the battery. Reconnect positive cable first and negative cable last.

13.Battery acid is poisonous and can cause burns. Avoid contact with skin, eyes and clothing. Protect your face, eyes and clothing when working with a battery.

14.Battery gases can explode. Keep cigarettes, sparks and flames away from the battery.

15.At the time of manufacture, the machine conformed to the safety standards for riding mowers. To assure op- timum performance and continued safety certification of the machine, use genuine Toro replacement parts and accessories. Replacement parts and accessories made by other manufacturers may result in non-conformance with the safety standards and the warranty may be voided.

16.When changing attachments, tires or performing other service, use correct blocks, hoists and jacks. Make sure machine is parked on a solid level surface such as a concrete floor. Prior to raising the machine, re- move any attachments that may interfere with the safe and proper raising of the machine. Always chock or block wheels. Use appropriate jack stands to support the raised machine. If the machine is not properly sup- ported by jack stands, the machine may move or fall, which may result in personal injury (see Jacking Instruc- tions in this chapter).
