IMPORTANT SAFETY INSTRUCTIONS

WARNING:
READ AND UNDERSTAND ALL INSTRUCTIONS.
Failure to follow all instructions listed below and on the machine may result in electric shock, fire, and/or serious personal injury.

READ ALL INSTRUCTIONS

• This cutting machine is capable of amputating hands and feet and throwing objects. Failure to observe all safety instructions could result in serious injury or death.

• Avoid dangerous environment – Do not use the lawnmower in damp or wet conditions or operate in the rain.

• Keep children away – Keep all bystanders, children, and pets at least 100 ft. away. Stop the machine if anyone enters the area.

• Tragic accidents can occur if the operator is not alert to the presence of children. Children are often attracted to the machine and the mowing activity. Never assume that children will remain where you last saw them.
  • Keep children out of the mowing area and under the watchful care of a responsible adult other than the operator.
  • Be alert and turn the mower off if a child enters the area.
  • Never allow children to operate the machine.
  • Use extra care when approaching blind corners, shrubs, trees, or other objects that may block your view of a child.

• Dress properly – Wear heavy, long pants, long sleeves, gloves, and protective footwear that will protect your feet and improve your footing on slippery surfaces. Do not wear loose-fitting clothing, short pants, sandals, or go barefoot. Do not wear jewelry of any kind. They can be caught in moving parts.

• Don’t overreach – Keep proper footing and balance at all times. Overreaching can result in loss of balance.

• Do not leave the mower unattended while running or with the start key installed.

• Keep hands and feet away from the cutting area. Keep clear of the discharge opening at all times.

• Operate the lawnmower only in daylight or good artificial light.

• Use safety glasses – Always wear eye protection with side shields marked to comply with ANSI Z87.1. Use a face mask if the operation is dusty.

• Use the right appliance – Do not use the lawnmower for any job except that for which it is intended.

• Do not force the lawnmower – It will do the job better and safer at the rate for which it was designed.

• Do not charge batteries in rain, or in wet locations.

• Stay alert – Watch what you are doing and use common sense when operating the lawnmower. Do not operate the mower while tired, upset, or under the influence of drugs, alcohol, or medication. A moment of inattention while operating the lawnmower may result in serious personal injury.

• Maintain lawnmower with care – Keep the machine in good working condition. Keep blades sharp and guards in place and in working order. Replace damaged or unevenly worn blades before using the mower for best performance.

• Check all nuts, bolts, and screws at frequent intervals for proper tightness to be sure the equipment is in safe working condition. The mower blades are sharp. Wrap the blade or wear gloves, and use extra caution when servicing them.

• Do not dispose of the battery in a fire. The cell may explode. Check with local codes for possible special disposal instructions.

• Stop the motor, wait until the blade comes to a complete stop, and remove the start key and battery pack before performing any maintenance, cleaning the lawnmower, removing the grass catcher, or removing the mulching plug.

• Never use a hose, water, or any liquids to clean or rinse off the lawnmower. Corrosive liquids, water, fertilizers, and chemicals used to treat lawns can enter the lawnmower and/or battery compartment and damage electronic components and/or the battery pack, which can result in a short circuit, increased risk of fire, and serious personal injury. Remove any buildup of grass and leaves on or around the mower housing and/or underneath the mower deck. Wipe the mower clean with a dry cloth occasionally.

• Replace the blade if it is bent or cracked. An unbalanced blade causes a vibration that could damage the motor drive unit or cause personal injury. Sharpen a dull blade equally at each end to maintain the balance. Clean the blade thoroughly and check its balance by supporting it horizontally on a thin nail through its center hole. The nail should be in a horizontal position. If either end of the blade rotates downward, remove some metal from the heavy or lower end until the blade is balanced. It is balanced when neither end drops.

• Always use safety protective devices. Do not operate the mower without the entire grass catcher or mulching plug and rear discharge door in place and working properly.

• Do not open or mutilate the battery. Released electrolyte is corrosive and may cause damage to the eyes or skin. It may be toxic if swallowed.

• Follow manufacturer’s instructions for proper operation and installation of accessories. Only use accessories approved by the manufacturer.

• Exercise care in handling batteries in order not to short the battery with conducting materials such as rings, bracelets, and keys. The battery or conductor may overheat and cause burns.

• Clear the work area before each use. Remove all objects such as rocks, tree nuts, sticks, metal, wire, bones, toys, or other objects which can be thrown by the blade. Stay behind the handle when the motor is running.

• Prevent unintentional starting. Ensure the switch is in the off-position before connecting to the battery pack, picking up, or carrying the appliance. Carrying the appliance with your finger on the switch or energizing an appliance that has the switch on invites accidents.

• When the 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.

• 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.

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

• Do not expose a battery pack or appliance to fire or excessive temperature. Exposure to fire or temperature above 265°F may cause an explosion.

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

• Do not modify or attempt to repair the appliance or the battery pack (as applicable) except as indicated in the instructions for use and care.

• Avoid holes, ruts, bumps, rocks, property stakes, or other hidden objects. Uneven terrain could cause a slip and fall accident.

• Do not mow near drop-offs, ditches, or embankments.

• Mow across the face of slopes, never up and down. Exercise extreme caution when changing direction on slopes.

• Plan your mowing pattern to avoid discharge of material toward roads, sidewalks, bystanders, and the like. Also, avoid discharging material against a wall or obstruction, which may cause the material to ricochet back toward the operator.

• Do not mow on wet grass or excessively steep slopes. Poor footing could cause a slip and fall accident. Walk, never run.

• Use extra care when approaching blind corners, shrubs, trees, or other objects that may block your view.

• Do not pull the mower backward unless absolutely necessary. If you must back the mower away from a wall or obstruction, first look down and behind to avoid tripping or pulling the mower over your feet.

• Never direct discharged material toward anyone. Avoid discharging material against a wall or obstruction. Material may ricochet back toward the operator. Stop the blade when crossing gravel surfaces.

• Objects struck by the lawnmower blade can cause severe injuries to persons. The lawn should always be carefully examined and cleared of all objects prior to each mowing.

• If the lawnmower strikes a foreign object, follow these steps:
  • Stop the lawnmower by releasing the blade control lever, wait until the blade comes to a complete stop, and then remove the start key.
  • Thoroughly inspect the mower for any damage.
  • Replace the blade if it is damaged in any way. Repair any damage before restarting and continuing to operate the mower.

• Stop the motor, wait until the blade comes to a complete stop, and remove the start key before unclogging the chute. The cutting blade continues to rotate for a few seconds after the motor is shut off. Never place any part of the body in the blade area until you are sure the blade has stopped rotating.

• If the mower should start to vibrate abnormally, stop the motor, remove the start key, and check immediately for the cause. Replace the blade if it is unevenly worn or damaged in any way. Vibration is generally a warning of trouble.

• Service on the product must be performed by qualified repair personnel only. Service or maintenance performed by unqualified personnel could result in injury to the user or damage to the product.

• The grass catcher assembly is subject to deterioration and wear and should be checked each time the mower is used. If replacement is needed, make sure the new grass catcher meets the original manufacturer’s recommendations and specifications.

• Use only authorized replacement parts when servicing the product. Use identical replacement blades only. The use of unauthorized parts may create a risk of serious injury to the user, or damage to the product.

• Maintain or replace safety instructions labels, as necessary.

• Disconnect battery and remove start key. Disconnect battery pack and remote start key from the appliance before storing, servicing, or changing accessories such as blades. Such preventive safety measures reduce the risk of starting the tool accidentally.

• Stop the unit and disconnect the battery pack and start the key when not in use. Carry or push the unit with the motor stopped and the start key removed from the mower.

• Battery tools do not have to be plugged into an electrical outlet; therefore, they are always in operating condition. Be aware of possible hazards when not using your battery tool or when changing accessories. Following this rule will reduce the risk of electric shock, fire, or serious personal injury.

• Do not use the battery-operated appliance in rain.

• Remove or disconnect the battery before servicing, cleaning, or removing material from the gardening appliance.

• Use this product only with batteries and chargers listed in tool/appliance/battery pack/charger correlation supplement 988000-842.
