General Machine Safety Warnings

Image 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. A. Keep work area clean and well lit. Cluttered or dark areas invite accidents.
    2. B. 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. C. Keep children and bystanders away while operating the machine. Distractions can cause you to lose control.
  2. Electrical safety
    1. A. 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. B. 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. C. Do not expose the machine to rain or wet conditions. Water entering a machine will increase the risk of electric shock.
    4. D. 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. E. 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. F. 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. A. 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. B. 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. C. 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. D. 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. E. Do not overreach. Keep proper footing and balance at all times. This enables better control of the machine in unexpected situations.
    6. F. 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. G. 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.
    8. H. Do not let familiarity gained from frequent use of the machine allow you to become complacent and ignore machine safety principles. A careless action can cause severe injury within a fraction of a second.
  4. Machine use and care
    1. A. 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. B. 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. C. 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. D. 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. E. 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. F. 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. G. 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. H. 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. A. 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. B. Use the machine only with specifically designated batteries. Use of any other batteries may create a risk of injury and fire.
    3. C. 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. D. 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. E. 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. F. Do not expose a battery pack or machine to fire or excessive temperature. Exposure to fire temperature above 130°C (265°F) may cause an explosion.
    7. G. Follow all charging instructions and do not charge the battery pack or machine outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.
  6. Service
    1. A. 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. B. 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
  • 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.
  • 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.
  • 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. The operator is 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.
    • Use an angle indicator to determine the approximate slope angle of the area.
    • Never operate on slopes greater than 15°.
    • 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.
  • 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 hand trimmer to mow the grass in these areas.

    3.  Water
    4.  W = Width of the machine
    5.  Keep a safe distance (twice the width of the machine) between the machine and any hazard.
  • 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.
  • Remove or mark obstacles such as ditches, holes, ruts, bumps, rocks, or other hidden hazards. Tall grass can hide obstacles. Uneven terrain could overturn the machine.
  • Use extra care while operating with accessories or attachments, such as grass-collection systems. These can change the stability of the machine and cause a loss of control. Follow directions for counterweights.
  • If possible, keep the deck lowered to the ground while operating on slopes. Raising the deck while operating on slopes can cause the machine to become unstable.
Starting the Machine
  1. Sit on the seat.
  2. Turn the key switch past the On position and release it.
  3. Wait for the splash screen to disappear from the information display before operating the machine (approximately 3 to 5 seconds).
Shutting Off the Machine
Caution

Driving the Machine
Caution
Positioning one lever too far in front of the other causes the machine to spin very rapidly. As a result, you may lose control of the machine, causing personal injury to you and damage to the machine.
Slow down the machine before making sharp turns.
 
The drive wheels turn independently, powered by motors on each axle. You can turn 1 side in reverse while you turn the other forward, causing the machine to spin rather than turn. This greatly improves the machine maneuverability but may require some time for you to adapt to how it moves.
  1. Move the motion-control levers down to the center, unlocked position.

    Note: You can use the parking brake to stop the machine in emergency situations or when a machine fault disables the traction controls.
Operating the Mower Blade-Control Switch (PTO)
Danger
The rotating blades under the mower deck are dangerous. Blade contact will cause serious injury or death.
Do not put your hands or feet under the mower or mower deck when the blades are engaged.
 
Danger
An uncovered discharge opening allows objects to be thrown toward you or bystanders. Also, contact with the blade could occur. Thrown objects or blade contact will cause serious injury or death.
Do not operate the mower with the discharge deflector raised, removed, or altered unless a grass collection system or mulch kit is in place and working properly.
 
  1. Engage the blade-control switch (PTO).
    Graphic
    G428133
  2. Mow as desired.
  3. Disengage the blade-control switch.
    Graphic
    G428132
Side Discharge
The hinged grass deflector disperses clippings to the side and down toward the turf.
Danger
Without the grass deflector, discharge cover, or complete grass catcher assembly mounted in place, you and bystanders are exposed to blade contact and thrown debris. Contact with rotating mower blade(s) and thrown debris will cause injury or death.
  • Do not remove the grass deflector from the machine, because the grass deflector routes material down toward the turf. If the grass deflector is ever damaged, replace it immediately.
  • Never put your hands or feet under the mower.
  • Never try to clear the discharge area or mower blades unless the power takeoff (PTO) is off. Rotate the key to the Off position and remove the key.
 
Adjusting the Height of Cut
  1. Use the height-of-cut lever to the right of the operating position to adjust the height of cut from 38 to 114 mm (1-1/2 to 4-1/2 inches) in 13 mm (1/2 inch) increments.
    Note: The transport position is the highest height-of-cut position.
    Graphic
    G441492
Adjusting the Anti-Scalp Rollers
Whenever you change the height of cut, adjust the height of the anti-scalp rollers.
  1. Park the machine on a level surface, disengage the blade-control switch (PTO), and engage the parking brake.
  2. Shut off the machine, remove the key, and wait for all moving parts to stop before leaving the operating position.
  3. Adjust the anti-scalp rollers to match the closest height-of-cut position.
    Note: Adjust the anti-scalp rollers so that the rollers do not touch the ground in normal, flat mowing areas.
    Graphic
    G444946
Operating Tips
Maximize Air Circulation
For best mowing and maximum air circulation, operate the machine with the blade-control switch (PTO) in the Fast position. Air circulation is required to thoroughly cut grass clippings, so do not set the height-of-cut so low as to totally surround the mower deck in uncut grass. Always try to have 1 side of the mower deck free from uncut grass, which allows air to be drawn into the mower deck.
Avoid Cutting Too Low
When mowing uneven ground, raise the cutting height to slightly higher than normal to avoid scalping the turf. However, the cutting height used in the past is generally the best one to use. When cutting grass longer than 15 cm (6 inches) tall, you may want to cut the lawn twice to ensure an acceptable quality of cut.
Cut a Third of the Grass Blade
It is best to cut only about a third of the grass blade. Cutting more than that is not recommended unless grass is sparse, or it is late fall when grass grows more slowly.
Alternate the Mowing Direction
Alternate the mowing direction to keep the grass standing straight. This also helps disperse clippings, which enhances decomposition and fertilization.
Mowing Frequency
Grass grows at different rates at different times of the year. To maintain the same cutting height, mow more often in early spring. As the grass growth rate slows in mid summer, mow less frequently. If you cannot mow for an extended period, first mow at a high cutting height, then mow again 2 days later at a lower height setting.
Mow at Slower Ground Speeds
In certain conditions, mowing at a slower ground speed can improve cut quality.
Avoid Grass Clumps
If you must stop driving forward while mowing, a clump of grass clippings may drop onto your lawn. To avoid this, move onto a previously cut area with the blades engaged or disengage the mower deck while moving forward.
Keep the Underside of the Mower Deck Clean
Clean clippings and dirt from the underside of the mower deck after each use. Grass and dirt build-up will eventually decrease the cutting quality.
Maintain the Blades
Maintain a sharp blade throughout the cutting season because a sharp blade cuts cleanly without tearing or shredding the grass blades. Tearing and shredding turns grass brown at the edges, which slows growth and increases the chance of disease. Check the mower blades after each use for sharpness, and for any wear or damage. File down any nicks and sharpen the blades as necessary. If a blade is damaged or worn, replace it.

After Operation

After Operation Safety
  • Disengage the PTO whenever you are transporting or not using the machine.
  • Use full-width ramps for loading the machine into a trailer or truck.
  • Tie the machine down securely using straps, chains, cable, or ropes. Both front and rear straps should be directed down and outward from the machine.
  • Replace all worn, damaged, or missing parts and decals. Keep all fasteners tight to ensure that the machine is working properly.
