Introduction Safety Read this manual carefully to learn how to operate and maintain your product properly. The information in this manual can help you and others avoid injury and product damage. Although Toro designs and produces safe products, you are responsible for operating the product properly and safely. Hazard control and accident prevention are dependent upon the awareness, concern, and proper training of the personnel involved in the operation, transport, maintenance, and storage of the machine.
• Safety interlock switches are for the operators protection. Disconnected or malfunctioning safety interlock switches could allow the machine to operate in an unsafe manner and may cause personal injury. with terrain angles, ricochets, or missing or damaged guards, can lead to thrown object injuries. Do not resume sweeping until area is cleared. • NEVER carry passengers. – Do not disconnect the safety interlock switches.
Maintenance – Avoid sudden stops and starts. – Do not go from reverse to forward or forward to reverse without first coming to a complete stop. • Hydraulic fluid escaping under pressure can penetrate skin and do serious damage. Keep body and hands away from pin hole leaks or nozzles that eject high pressure hydraulic fluid. Use cardboard or paper to find hydraulic leaks.
• Performing maintenance on machine not properly supported with jack stands may cause machine to fall and could cause injury. • Do not over speed the engine by changing the governor settings. Maximum engine rpm with no load is 3000 rpm. To ensure safety and accuracy, have an Authorized TORO Distributor check maximum engine speed with a tachometer. • Engine must be shut off before checking oil or adding oil to the crankcase.
Safety and Instruction Decals Safety decals and instructions are easily visible to the operator and are located near any area of potential danger. Replace any decal that is damaged or lost.

Check Crankcase Oil Fill Fuel Tank With Gasoline The engine is shipped with 2.1 quarts (2 liters) of oil (with filter) in the crankcase; however, level of oil must be checked before the engine is first started. Danger IN CERTAIN CONDITIONS GASOLINE IS EXTREMELY FLAMMABLE AND HIGHLY EXPLOSIVE. A FIRE OR EXPLOSION FROM GASOLINE CAN BURN YOU AND OTHERS AND CAUSE PROPERTY DAMAGE. 1. Position the sweeper on a level surface and make sure engine is off. 2. Remove the dipstick and wipe it with a clean rag.
1. Use a clean rag to clean area around fuel tank cap. 3. Wipe up any gasoline that may have spilled to prevent a fire hazard. 2. Remove the cap from the fuel tank and fill the 5 gallon tank to within 1 inch (25 mm) from the top with unleaded gasoline. Install fuel cap tightly. 1 Figure 2 1. Fuel tank cap Check Hydraulic System Oil Check level of hydraulic fluid before engine is first started and daily thereafter.
Check Torque of Wheel Nuts Important To prevent system contamination, clean top of hydraulic oil containers before opening. Assure pour spout and funnel are clean. When adding oil to the hydraulic system, use a funnel with a fine screen–200 mesh–and ensure funnel and oil are clean. This procedure prevents accidental contamination of the hydraulic oil which will damage the hydraulic system.
Know Your Controls adding oil does not cause light to go out when engine is restarted, turn off engine immediately and contact your local Authorized TORO Distributor for assistance. Choke (Fig. 5)–To start a cold engine, move the choke control forward to close the choke. After engine starts, regulate choke to keep engine running smoothly. As soon as possible, move the choke backward to open the choke. A warm engine requires little or no choking. 1 2 3 4 5 Ignition Key Switch (Fig.
Seat Adjusting Lever (Fig. 6) – To adjust fore and aft position of seat, move lever on left side of seat outward, slide seat to desired position, and release lever so it will lock in position. Caution UNEXPECTED MOVEMENT OF THE MACHINE CAUSED BY AN IMPROPERLY ADJUSTED TRACTION PEDAL MAY CAUSE PERSONAL INJURY. 2 • When foot is removed from traction pedal, the machine should stop; it must not move In either direction. If machine does move, do not operate until.
Caution ACCIDENTAL MOVEMENT OF MACHINE DUE TO PARKING BRAKE NOT BEING SET MAY CAUSE PERSONAL INJURY. • The hydrostatic transmission will not, at any time, act as a parking brake for the machine. To engage parking brake, pull back on lever. • Whenever the engine is shut off, the parking brake must be engaged to prevent accidental movement of the machine. 1 Hopper Door Release Handle (Fig. 9) – The hopper is dumped manually with the hopper door release handle. Figure 10 1.
Operation B. A disconnected or malfunctioning safety interlock switch could allow the engine to continue running when the Reel PTO Engagement handle is in the HIGH or LOW (engaged) position or the traction pedal is depressed with the operator off the seat. Warning Caution ROTATING PARTS CAN CAUSE SERIOUS PERSONAL INJURY • Keep hands and feet away from sweeper reels while machine is running. • Keep hands, feet, hair, and clothing away from all moving parts to prevent injury.
The engine provides power to both the hydrostatic transmission and the sweeper reels. An increasing load on the hydrostatic transmission, such as hill climbing or a full hopper, will result in less power available to the sweeper reels, thereby decreasing the efficiency of debris pickup. To maintain enough power for the sweeper reels while operating, regulate traction pedal to keep engine speed high and somewhat constant.
While Sweeping Dumping the Hopper Danger Danger TIP OVER CAN CAUSE SERIOUS INJURY OR DEATH. TIP OVER/ELECTRICAL SHOCK COULD CAUSE SERIOUS INJURY OR DEATH. • NEVER operate on steep slopes. • Sweep slopes up and down, never across the face. • When going uphill or downhill, do not stop or start suddenly. • Stay alert for holes in the terrain or other hidden hazards. To avoid tipping or loss of control, do not drive close to a ditch, creek or drop off.
Lubrication Lubricate Fittings and Bearings The sweeper has four self–sealing bearings and two grease fittings that must be lubricated regularly with No, 2 General Purpose Lithium Base Grease. it machine is operated under normal conditions, lubricate all bearings and bushings after every 50 hours of operation or immediately after every washing. Bearings and bushings must be lubricated daily when operating conditions are extremely dusty and dirty.
Maintenance Changing Engine Oil and Filter Important This product contains an exhaust emission certified engine. Always refer to the engine manufacturer’s owner’s manual for maintenance and service requirements concerning the emission control system. Note: For further information on engine operation, maintenance, and repair of engine, refer to engine manufacturer’s owner’s manual. In some cases TORO may recommend more frequent maintenance intervals than the engine manufacturer.

Air cleaner cover 2. Air cleaner cover knob 3. Remove precleaner from paper element. 4. Wash precleaner in warm water with detergent. Rinse precleaner thoroughly until all traces of detergent are eliminated. Squeeze out excess water. (Do not wring.) Allow precleaner to air dry.
6. When servicing air cleaner, check the air cleaner base. Make sure it is secured and not bent or damaged. Check element cover for damage or improper fit. Replace all damaged air cleaner components. 0.030 in (0.76mm) Note: Before reassembling air cleaner make sure rubber seal is in position around stud. Inspect and make sure it is not damaged. Seal with the element cover. 7. Reinstall the air cleaner paper element, precleaner, element cover, element cover nut, and air cleaner cover.
Important Using Mobil DTE 26 or equivalent ISO VG 68 hydraulic oil when temperatures average below 80_ F (26.7_ C) could cause serious hydraulic system damage. The hydraulic vacuum gauge measures the vacuum levels within the hydraulic system. When the hydraulic oil filter becomes dirty, the vacuum level within the system will increase. The vacuum level will also increase if the wrong viscosity oil is used. (Refer to Expected Ambient Temperatures table.
mesh) and ensure funnel and oil are clean. This procedure prevents accidental contamination of the hydraulic oil which will damage the hydraulic system. 6. Place all controls in the neutral or disengaged position and start engine. Run engine at idle for 3–5 minutes to circulate hydraulic fluid and remove any air trapped in the system. Stop the engine and re–check the fluid level. (Refer to Check Hydraulic System Oil) 1 7. Check all connections for leaks. Figure 24 Danger 1.
Note: The inside and outside of the belt are not the same. When looking at the front reel pulley (Fig. 25), with the belt installed, there should be two wide grooves on either side visible. Tighten the idler adjustment arm by pulling rearward with approximately 30 lbs. Torque both clamping bolts to 48 ft–lbs. Do not use a lever or a pry–bar for mechanical advantage when tensioning the belt with the idler adjustment arm. 6. Adjust the left–hand side.
1. Position machine on a level surface, shut the engine off, and remove the key from the ignition switch. Do not set the parking brake. 2. Adjust the air gap to .018” (.5mm) by inserting a thickness gauge into the clutch inspection slots. Evenly tighten the three lock nuts on clutch to reduce the air gap. Caution Performing maintenance on machine not properly supported with jack stands may cause machine to fall and could cause injury. 2.
8. Test drive machine to be sure it does not creep. Steering Chain Adjustment The steering chain should be adjusted after 100 hours of operation or when steering system is binding or excessive play in the column occurs. 1. Adjust steering chain idler, by applying 5 lbs. of force to the midpoint of the chain, until it deflects 0.25 inches. Figure 29 Note: The puller may be used in either direction for right or left handed use. 1 To remove reel fingers: 1. Place the end of the puller on the finger. 2.
Battery Care Warning ELECTROLYTES CONTAINED IN BATTERIES COULD CAUSE BURNS. GASSES PRODUCED WHILE CHARGING ARE EXPLOSIVE AND IF IGNITED BY SPARK OR FLAME MAY CAUSE SERIOUS INJURY. ALSO NAUSEA MAY RESULT IF GASSES ARE INHALED. • Wear safety glasses and rubber gloves when working with electrolyte. • Charge battery in a well ventilated place so gasses produced while charging can dissipate. • Keep open flames and electrical spark away from the battery; DO NOT SMOKE.
