Safety ◊ lack of awareness of the effect of ground conditions, especially slopes; ◊ incorrect hitching and load distribution. Improper use or maintenance by the operator or owner can result in injury. To reduce the potential for injury, comply with these safety instructions and always pay attention to the safety alert symbol, which means Caution, Warning, or Danger—personal safety instruction. Failure to comply with the instruction may result in personal injury or death.
• When operating near drop offs or bodies of water, do not use on slopes greater than 15 degrees. • Disengage drive to attachments when transporting, not in use or any time the attachment is in the raised position. • Stop the engine and disengage drive to attachment: – before refuelling; – before making height adjustment unless adjustment can be made from the operators position. • Use only Toro approved attachments. • Use care when pulling loads or using heavy equipment.
• Never store the equipment with fuel in the tank inside a building where fumes may reach an open flame or spark. • Replace worn or damaged parts for safety. • Allow the engine to cool before storing in any enclosure. • When machine is to be parked, stored or left unattended, lower the attachment unless a positive mechanical lock is used. • If the fuel tank has to be drained, do this outdoors.

Maintenance Recommended Maintenance Schedule(s) Maintenance Service Interval After the rst 10 operating hours Maintenance Procedure • Torque the frame mounting bolts. • Torque wheel lug nuts. Every 50 hours • Lubricate grease ttings • Check the tire pressure. Every 200 hours • Torque wheel lug nuts. If you leave the key in the ignition switch, someone could accidently start the engine and seriously injure you or other bystanders. Remove the key from the ignition before you do any maintenance.
Drive System Maintenance Checking the Tire Pressure Check the tire pressure every 50 hours (Figure 130). Maintain the air pressure in the tires at 35 psi . Uneven tire pressure can cause lose of traction. If a lose of traction occurs, tire pressure may be increased to 50 psi to increase track tension. Check the tires when they are cold to get the most accurate pressure reading. Figure 129 1. PTO shaft bearings (2) 2. Hydraulic cylinder pivot pins (2) 3.

Note: You may need to move the floor jack to the rear bumper to raise the rear of the machine high enough to install the flat washer and locknut. Note: The front and center wheels can be removed without raising and supporting the rear of the machine. Figure 131 1. Access covers 3. Loosen and remove the locknut and flat washer from the bogie pivot weldment (Figure 132). Figure 132 1.
Storage Machine 1. Thoroughly clean the machine and cab, paying special attention to these areas: • PTO shaft assembly • All grease fittings and pivot points • Oil the spline on the PTO output shaft to prevent rusting 2. Check and adjust tire pressure; refer to Checking Tire Pressure in Drive System Maintenance, page 48. 3. Check all fasteners for looseness and tighten them as necessary. Especially torque the 5 bolts securing the winter frame to the traction unit to 265 ft-lb (359 N⋅m). 4.
