Safety

General Machine Safety Warnings

Graphic WARNING—Read all safety warnings, instructions, illustrations and specifications provided with this machine.

Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

The term “machine” in all of the warnings listed below refers to your mains-operated (corded) machine or battery-operated (cordless) machine.

  1. Work area safety

    1. Keep work area clean and well lit.Cluttered or dark areas invite accidents.

    2. Do not operate the machine in explosive atmospheres, such as in the presence of flammable liquids, gasses, or dust.The machine creates sparks, which may ignite the dust or fumes.

    3. Keep children and bystanders away while operating the machine.Distractions can cause you to lose control.

  2. Electrical safety

    1. Machine plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with an earthed (grounded) machine.Unmodified plugs and matching outlets will reduce risk of electric shock.

    2. Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges, and refrigerators.There is an increased risk of electric shock if your body is earthed or grounded.

    3. Do not expose the machine to rain or wet conditions.Water entering a machine will increase the risk of electric shock.

    4. Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the machine. Keep cord away from heat, oil, sharp edges, or moving parts.Damaged or entangled cords increase the risk of electric shock.

    5. When operating the machine outdoors, use an extension cord suitable for outdoor use.Use of a cord suitable for outdoor use reduces the risk of electric shock.

    6. If operating the machine in a damp location is unavoidable, use a residual current device (RCD) protected supply.Use of an RCD reduces the risk of electric shock.

  3. Personal safety

    1. Stay alert, watch what you are doing, and use common sense when operating the machine. Do not use the machine while you are tired or under the influence of drugs, alcohol, or medication.A moment of inattention while operating the machine may result in serious personal injury.

    2. Use personal protective equipment. Always wear eye protection.Protective equipment such as a dust mask, non-skid safety shoes, or hearing protection used for appropriate conditions will reduce personal injuries.

    3. Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack.Energising a machine that has the switch on invites accidents.

    4. Remove any adjusting key or wrench before turning the machine on.A wrench or a key left attached to a rotating part of the machine may result in personal injury.

    5. Do not overreach. Keep proper footing and balance at all times.This enables better control of the machine in unexpected situations.

    6. Dress properly. Do not wear loose clothing or jewelry. Keep your hair and clothing away from moving parts.Loose clothes, jewelry or long hair can be caught in moving parts.

    7. If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used.Use of dust collection can reduce dust-related hazards.

  4. Machine use and care

    1. Do not force the machine. Use the correct machine for your application.The correct machine will do the job better and safer at the rate for which it was designed.

    2. Do not use the machine if the switch does not turn it on and off.Any machine that cannot be controlled with the switch is dangerous and must be repaired.

    3. Disconnect the plug from the power source and/or remove the battery pack, if detachable, from the machine before making any adjustments, changing accessories, or storing the machine.Such preventive safety measures reduce the risk of starting the machine accidentally.

    4. Store an idle machine out of the reach of children and do not allow persons unfamiliar with the machine or these instructions to operate the machine.A machine is dangerous in the hands of untrained users.

    5. Maintain the machine and accessories. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the operation of the machine. If damaged, have the machine repaired before use.Many accidents are caused by a poorly maintained machine.

    6. Keep cutting tools sharp and clean.Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

    7. Use the machine, accessories, and tool bits etc., in accordance with these instructions, taking into account the working conditions and the work to be performed.Use of the machine for operations different from those intended could result in a hazardous situation.

    8. Keep handles and grasping surfaces dry, clean and free from oil and grease.Slippery handles and grasping surfaces do not allow for safe handling and control of the machine in unexpected situations.

  5. Battery machine use and care

    1. Recharge only with the charger specified by a manufacturer.A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.

    2. Use the machine only with specifically designated batteries.Use of any other batteries may create a risk of injury and fire.

    3. When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another.Shorting the battery terminals together may cause burns or a fire.

    4. Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help.Liquid ejected from the battery may cause irritation or burns.

    5. Do not use a battery pack or machine that is damaged or modified.Damaged or modified batteries may exhibit unpredictable behavior resulting in fire, explosion or risk or injury.

    6. Do not expose a battery pack or machine to fire or excessive temperature.Exposure to fire temperature above 130°C may cause an explosion.

    7. Follow all charging instructions and do not charge the battery pack or machine outside the temperature range specified in the instructions.Changing improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.

  6. Service

    1. Have your machine serviced by a qualified repair person using only identical replacement parts.This will ensure that the safety of the machine is maintained.

    2. Never service damaged battery packs.Service of battery packs should be performed only by the manufacturer or authorized service providers.

    During Operation

    During Operation Safety

    General Safety

    • Wet grass or leaves can cause serious injury if you slip and contact the blade. Avoid mowing in wet conditions.

    • Before you start the machine, ensure that all drives are in neutral.

    • Keep away from holes, ruts, bumps, rocks, and other hidden hazards. Use care when approaching blind corners, shrubs, trees, tall grass or other objects that may hide obstacles or obscure vision. Uneven terrain could overturn the machine or cause you to lose your balance or footing.

    • Shut off the machine and disengage the drive to the cutting unit after striking a foreign object or if an abnormal vibration occurs. Inspect the cutting unit for damage and make repairs before starting and operating the machine.

    • Be alert, slow down, and use caution when making turns and crossing roads and sidewalks with the machine. Always yield the right-of-way.

    • Do not use the machine as a towing vehicle.

    • Never raise the mower deck with the blades running.

    • Be aware of the mower discharge path and direct discharge away from others. Avoid discharging material against a wall or obstruction as the material may ricochet back toward the operator. Stop the blades, slow down, and use caution when crossing surfaces other than grass and when transporting the mower.

    • Do not leave a running machine unattended.

    • Be alert and shut off the machine if children enter the area.

    Slope Safety

    • Slopes are a major factor related to loss of control and rollover accidents, which can result in severe injury or death. You are responsible for safe slope operation. Operating the machine on any slope requires extra caution. Before using the machine on a slope, do the following:

      • Review and understand the slope instructions in the manual and on the machine.

      • Evaluate the site conditions of the day to determine if the slope is safe for machine operation. Use common sense and good judgment when performing this evaluation. Changes in the terrain, such as moisture, can quickly affect the operation of the machine on a slope.

    • Operate across slopes, never up and down. Avoid operation on excessively steep or wet slopes.

    • Identify hazards at the base of the slope. Do not operate the machine near drop-offs, ditches, embankments, water, or other hazards. The machine could suddenly roll over if a wheel goes over the edge or the edge collapses. Keep a safe distance (twice the width of the machine) between the machine and any hazard. Use a walk-behind machine or a handheld tool to operate in these areas.

    • Avoid starting, stopping, or turning the machine on slopes. Avoid making sudden changes in speed or direction; turn slowly and gradually.

    • Do not operate a machine under any conditions where traction, steering or stability is in question. Be aware that operating the machine on wet grass, across slopes or downhill may cause the machine to lose traction. Loss of traction to the drive wheels may result in sliding and a loss of braking and steering. The machine can slide even if the drive wheels are stopped.

    The batteries contain high voltage, which could burn or shock you.

    • Do not attempt to open the batteries.

    • Use extreme care when handling a battery with a cracked case.

    • Use only the charger designed for the batteries.

    The lithium-ion batteries hold a sufficient charge to perform intended work during its life span.

    To achieve maximum life and use from your batteries, follow these guidelines:

    • Do not open the battery.

    • Store/park the machine in a clean, dry garage or storage area, away from direct sunlight, heat sources, rain, and wet conditions. Do not store it in a location where the temperature exceeds the range specified in Battery Storage Requirements. Temperatures outside of this range will damage your batteries. High temperatures during storage, especially at a high state of charge, reduces the life of the batteries.

    • When storing the machine for more than 10 days, ensure that the machine is in a cool and dry location, out of sunlight, rain, and wet conditions.

    • If you are mowing in hot conditions or in strong, direct sunlight, the battery may overheat. If this happens, a high-temperature alert will appear on the InfoCenter, the cutting units will disengage, and the machine will slow down.

      Immediately drive the machine to a cool location out of the sun, turn off the machine, and allow the batteries to cool fully before resuming operation.

    • Maintain the sharpness of the mower blades. A dull blade increases power consumption and reduces the amount of work that the machine performs on each charge.

    • Use lights only when it is necessary.

    Maintaining the Battery Charger

    Important: All electrical repairs should be performed by an Authorized Toro Dealer only.

    The charger requires little maintenance other than protecting it from damage and weather.

    • Clean the battery-charger cords and case with a slightly damp cloth after each use.

      Note: Do not clean the dielectric grease from the terminals.

    • Coil the cords when not in use.

    • Periodically examine the cords for damage, and replace them when necessary with Toro-approved parts.

    Locating the Fuses

    The electrical system is protected by fuses. It requires no maintenance. Refer to the Service Manual for information on testing and servicing the fuses.

    Release the cushion from the rear of the machine and remove the rear access cover to access the fuses.

    9. Store the machine in a clean, dry, garage or storage area. Remove the key from the switch and store it in a memorable place. Cover the machine to protect it and keep it clean.

    10. For prolonged storage, follow the battery storage requirements; refer to Battery Storage Requirements.

    Battery Storage Requirements

    Note: You do not need to remove the batteries from the machine for storage.

    Refer to the temperature limits for storage in the following table:

    Temperature Limits for Storage

    Storage TemperatureAppropriate Storage Time
    45° to 55°C (113° to 131°F)1 week
    25° to 45°C (77° to 113°F) 3 weeks
    -20° to 25°C (-4° to 77°F)52 weeks

    Important: Temperatures outside of these ranges will damage your batteries.The temperature that the batteries are stored at will affect their long-term life. Storage for long periods of time at extreme temperatures will reduce the battery life. For temperatures above 25°C (77°F), only store the machine for the appropriate amount of time indicated in the table.

    • Before you store the machine, charge or discharge the batteries between 40% to 60% (54.3V to 57.3V).

      Note: A 50% charge is optimal to ensure a maximum battery life. When the batteries are charged to 100% before storage, the battery life shortens.If you anticipate that the machine will be stored for a longer period of time, charge the batteries to around 60%.

    • For every 6 months of storage, check the battery-charge level and ensure that it is between 40% to 60%. If the charge is below 40%, charge the batteries between 40% to 60%.

    • You can use a multimeter to check the charge level when the machine is off. Refer to the following table for the amount of voltage that is equal to the charge level:

      VoltageCharge Level
      57.3V60%
      55.4V50%
