Connecting the Machine to the Tow Vehicle Operation Before Operation 1. Before Operation Safety Connect the machine hitch to the tow vehicle using a 25 mm (1 inch) diameter safety approved hitch pin and safety clip (not supplied). Important: Use a high strength hitch pin that is approved for tow vehicle hitches. • The machine has different balance, weight, and handling characteristics compared to some other types of towed equipment.
Important: Do not allow the hydraulic lines, brake magnets to provide comfortable, safe braking. Changing the load weight, as well as uneven alternator and battery output, can result in unstable current flow to the brake magnets. the power cable, and the pendant cables to drag on the ground during operation. Avoid locations where they could become pinched or cut. 7. • The load control compensates for trailer load Connect the power harness to the tow vehicle (Figure 21 and Figure 22).
During Operation – Do not attempt sharp turns or abrupt maneuvers or other unsafe driving actions that may cause a loss of control. During Operation Safety – Be aware of your surroundings when turning or backing up the machine. Ensure that the area is clear and keep all bystanders out of the operating area. Proceed slowly. • The owner/operator can prevent and is responsible for accidents that may cause personal injury or property damage. – Watch out for traffic when near or crossing roads.
• Unload the machine or disconnect it from the tow at which you can travel up the same hill. Stopping distance increases when traveling down hills. vehicle while on a level surface. • Ensure that the machine is connected to the tow vehicle before unloading. – Reduce the weight of the load when traveling on steep hills and avoid piling the load high. • Do not travel with the machine in the fully raised position. This increases the risk of tipping over the machine.

Maintenance Note: Download a free copy of the schematic by visiting www.Toro.com and searching for your machine from the Manuals link on the home page. Maintenance Safety • Before servicing or adjusting the machine, stop the machine, shut off the engine, engage the parking brake, remove the key, and wait for all moving parts to stop. • Perform only those maintenance instructions described in this manual. If major repairs are ever needed or assistance is desired, contact an authorized Toro distributor.
g014131 Figure 54 g014134 Figure 57 Safety Checks At the start of each day, complete these safety checks before operating the machine. Report any safety problems to your supervisor. See the Safety Instructions in this manual for details. Note: Photocopy these pages and use them as a regular safety checklist Tires and Wheels • The recommended tire pressure is 172 kPa (25 g014132 psi) for 84 cm (33 inch) tires and 207 kPa (30 psi) for 81 cm (32 inch) tires, or as recommended by the tire manufacturer.
Hydraulic System Alternate fluids: If the Toro fluid is not available, other petroleum-based Universal Tractor Hydraulic Fluids (UTHF) may be used provided its specifications fall within the listed range for all the following material properties and it meets industry standards. We do not recommend the use of synthetic fluid. Consult with your lubricant distributor to identify a satisfactory product. • Check the hydraulic system for oil leaks.
3. Block the tires on the opposite side of the flat tire. 4. On the side with the tire to be changed, remove the 4 bolts holding the walking beam suspension bearings to the chassis. (Loosen but do not remove the outside wheel nuts to give more clearance for bearing bolts). 5. Hoist or jack the machine until the inside tire and walking beam axle assembly can be rolled out from underneath. Ensure that the machine is stable. 6. Remove the tire. 7. Repair the damaged tire. 8.
6. Turn on the conveyor belt. 7. If belt slips, tighten the tension bolts evenly (with machine off) half a turn and check again. Continue until the belt moves without any slippage. 8. Give both tensioning bolts another half turn. At this point you should have proper tension. 9. To verify, look underneath at the chassis cross member. The middle of the belt should just clear the chassis cross member when the machine is in the down position.
Otherwise, you will have to remove the drive roller to gain enough clearance to install these bolts. When installing the rear drive roller, ensure that the shaft connecting to the motor is on the left side. It has a keyhole cut into it for securing the drive sprocket. Before applying tension with the tensioner rods at the front of the machine, use your hands to manually center the belt at the front and rear. Track and tension the belt by following the instructions in the Maintenance Section of the manual.
