  • Know how to stop the machine and shut off the engine quickly.

  • Check that the operator's presence controls, safety switches, and shields are attached and functioning properly. Do not operate the machine unless they are functioning properly.

  • Locate the pinch-point areas marked on the machine and attachments; keep your hands and feet away from these areas.

  • Before operating the machine with an attachment, ensure that the attachment is properly installed and that it is a genuine Toro attachment. Read all the attachment manuals.

  • Evaluate the terrain to determine what accessories and attachments you need to properly and safely perform the job.

  • Have the property or work area marked for buried lines and other objects, and do not dig in marked areas; note the location of unmarked objects and structures, such as underground storage tanks, wells, and septic systems.

  • Inspect the area where you will use the equipment for uneven surfaces or hidden hazards.

  • Ensure that the area is clear of bystanders before operating the machine. Stop the machine if anyone enters the area.

Fuel Safety

  • Use extreme care when handling fuel. It is flammable and its vapors are explosive.

  • Extinguish all cigarettes, cigars, pipes, and other sources of ignition.

  • Use only an approved fuel container.

  • Do not remove the fuel cap or fill the fuel tank while the engine is running or hot.

  • Do not add or drain fuel in an enclosed space.

  • Do not store the machine or fuel container where there is an open flame, spark, or pilot light, such as on a water heater or other appliance.

  • If you spill fuel, do not attempt to start the engine; avoid creating any source of ignition until the fuel vapors have dissipated.

  • To prevent a static charge from igniting the fuel, remove the machine from the truck or trailer and refuel it on the ground, away from all vehicles. If this is not possible, place a portable fuel container on the ground, away from all vehicles, and fill it; then refuel the machine from the fuel container rather than from a fuel-dispenser nozzle.

  • Keep the fuel-dispenser nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete. Do not use a nozzle lock-open device.

Adding Fuel

Recommended Fuel

  • For best results, use only clean, fresh (less than 30 days old), unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method).

  • Ethanol: Gasoline with up to 10% ethanol (gasohol) or 15% MTBE (methyl tertiary butyl ether) by volume is acceptable. Ethanol and MTBE are not the same. Gasoline with 15% ethanol (E15) by volume is not approved for use. Never use gasoline that contains more than 10% ethanol by volume, such as E15 (contains 15% ethanol), E20 (contains 20% ethanol), or E85 (contains up to 85% ethanol). Using unapproved gasoline may cause performance problems and/or engine damage which may not be covered under warranty.

  • Do not use gasoline containing methanol.

  • Do not store fuel either in the fuel tank or fuel containers over the winter unless you use a fuel stabilizer.

  • Do not add oil to gasoline.

Using Stabilizer/Conditioner

Use fuel stabilizer/conditioner in the machine to keep the fuel fresh longer when used as directed by the fuel-stabilizer manufacturer.

Important: Do not use fuel additives containing methanol or ethanol.

During Operation Safety

General Safety

  • Do not exceed the rated operating capacity, as the machine may become unstable, which may result in loss of control.

  • Do not carry a load with the arms raised. Always carry loads close to the ground.

  • Use only Toro-approved attachments and accessories. Attachments can change the stability and the operating characteristics of the machine.

  • For machines with a platform:

    • Lower the loader arms before stepping off the platform.

    • Do not try to stabilize the machine by putting your foot on the ground. If you lose control of the machine, step off the platform and away from the machine.

    • Do not place your feet under the platform.

    • Do not move the machine unless you are standing with both feet on the platform and your hands are holding onto the reference bars.

  • Use your full attention while operating the machine. Do not engage in any activity that causes distractions; otherwise, injury or property damage may occur.

  • Look behind and down before backing up to ensure that the path is clear.

  • Never jerk the controls; use a steady motion.

  • The owner/user can prevent and is responsible for accidents that may cause personal injury or property damage.

  • Wear appropriate clothing including gloves, eye protection, long pants, substantial slip-resistant footwear, and hearing protection. Tie back long hair and do not wear loose clothing or loose jewelry.

  • Do not operate the machine when you are tired, ill, or under the influence of alcohol or drugs.

  • Never carry passengers and keep pets and bystanders away from the machine.

  • Operate the machine only in good light, keeping away from holes and hidden hazards.

  • Ensure that all the drives are in neutral and engage the parking brake (if equipped) before starting the engine. Start the engine only from the operator's position.

  • Use care when approaching blind corners, shrubs, trees, or other objects that may obscure vision.

  • Slow down and use caution when making turns and crossing roads and sidewalks. Watch for traffic.

  • Stop the attachment when you are not working.

  • Stop the machine, shut off the engine, remove the key, and inspect the machine if you strike an object. Make any necessary repairs before resuming operation.

  • Never run an engine in an enclosed area.

  • Never leave a running machine unattended.

  • Before leaving the operating position, do the following:

    • Park the machine on a level surface.

    • Lower the loader arms and disengage the auxiliary hydraulics.

    • Engage the parking brake (if equipped).

    • Shut off the engine and remove the key.

  • Do not operate the machine when there is the risk of lightning.

  • Operate the machine only in areas where there is sufficient clearance for you to safely maneuver. Be aware of obstacles in close proximity to you. Failure to maintain adequate distance from trees, walls, and other barriers may result in injury as the machine backs up during operation if you are not attentive to the surroundings.

  • Check for overhead clearance (i.e., electrical wires, branches, and doorways) before driving under any objects and do not contact them.

  • Do not overfill the attachment and always keep the load level when raising the loader arms. Items in the attachment could fall and cause injury.

Slope Safety

  • Operate the machine up and down slopes with the heavy end of the machine uphill. Weight distribution changes with attachments. An empty bucket makes the rear of the machine the heavy end, and a full bucket makes the front of the machine the heavy end. Most other attachments make the front of machine the heavy end.

  • Raising the loader arms on a slope affects the stability of the machine. Keep the loader arms in the lowered position when on slopes.

  • Slopes are a major factor related to loss of control and tip-over accidents, which can result in severe injury or death. Operating the machine on any slope or uneven terrain requires extra caution.

  • Establish your own procedures and rules for operating on slopes. These procedures must include surveying the site to determine which slopes are safe for machine operation. Always use common sense and good judgment when performing this survey.

  • Slow down and use extra care on hillsides. Ground conditions can affect the stability of the machine.

  • Avoid starting or stopping on a slope. If the machine loses traction, proceed slowly, straight down the slope.

  • Avoid turning on slopes. If you must turn, turn slowly and keep the heavy end of the machine uphill.

  • Keep all movements on slopes slow and gradual. Do not make sudden changes in speed or direction.

  • If you feel uneasy operating the machine on a slope, do not do it.

  • Watch for holes, ruts, or bumps, as uneven terrain could overturn the machine. Tall grass can hide obstacles.

  • Use caution when operating on wet surfaces. Reduced traction could cause sliding.

  • Evaluate the area to ensure that the ground is stable enough to support the machine.

  • Use caution when operating the machine near the following:

    • Drop-offs

    • Ditches

    • Embankments

    • Bodies of water

    The machine could suddenly roll over if a track goes over the edge or the edge caves in. Maintain a safe distance between the machine and any hazard.

  • Do not remove or add attachments on a slope.

  • Do not park the machine on a hillside or slope.

Utility Line Safety

  • If you strike a utility line, do the following:

    • Shut off the machine and remove the key.

    • Remove all individuals from the work area.

    • Immediately contact the proper emergency and utility authorities to secure the area.

    • If you damage a fiber-optic cable, do not look into the exposed light.

  • Do not leave the operator’s platform if the machine is charged with electricity. You will be safe as long as you do not leave the platform.

    • Touching any part of the machine may ground you.

    • Do not allow another individual to touch or approach the machine when charged.

    • Always assume the machine is charged if you strike an electrical or communication line. Do not attempt to leave the machine.

  • Leaking gas is both flammable and explosive and may cause serious injury or death. Do not smoke while operating the machine.

Starting the Engine

  1. Ensure that the auxiliary hydraulics lever is in the NEUTRAL position.

  2. Move the choke lever fully forward if you are starting a cold engine.

    Note: A warm or hot engine may not require choking.

  3. Move the throttle lever midway between the SLOW and FAST positions.

  4. Insert the key into the key switch and turn it to the START position. When the engines starts, release the key.

    Important: Do not engage the starter for more than 10 seconds at a time. If the engine fails to start, wait 30 seconds for the starter to cool down between attempts. Failure to follow these instructions could burn out the starter motor.

  5. After the engine starts, gradually move the choke lever back to the OFF position. If the engine stalls or hesitates, move the choke forward again until the engine warms up.

  6. Move the throttle lever to the desired setting.

    Important: Running the engine at high speeds when the hydraulic system is cold (i.e., when the air temperature is at or below freezing) could damage the hydraulic system. When starting the engine in cold conditions, allow it to run in the middle throttle position for 2 to 5 minutes before moving the throttle to the FAST position.

    Note: If the outdoor temperature is below freezing, store the machine in a garage to keep it warmer and to aid in starting.

Driving the Machine

Use the traction control to move the machine. The farther you move the traction control in any direction, the faster the machine moves in that direction. Release the traction control to stop the machine.

The throttle control regulates the engine speed as measured in rpm (revolutions per minute). Place the throttle lever in the FAST position for best performance. You can, however, use the throttle position to operate at slower speeds.

Shutting Off the Engine

  1. Park the machine on a level surface, engage the parking brake, and lower the loader arms.

  2. Ensure that the auxiliary hydraulics lever is in the NEUTRAL position.
