READ ALL INSTRUCTIONS

DANGER

• This machine was built to be operated according to the rules for safe operation included in this manual.
• As with any type of power equipment, carelessness or error on the part of the operator can result in serious injury. This machine is capable of amputating hands and feet and throwing objects.
• Failure to observe all safety instructions could result in serious injury or death.

WARNING

• When using electric lawnmowers, basic safety precautions should always be followed to reduce the risk of fire, electric shock, and personal injury. These basic precautions include the following:

CHILDREN AND BYSTANDERS

Tragic accidents can occur if the operator is not alert to the presence of children or bystanders.

• Keep the area of operation clear of all persons, particularly small children, and pets.
• Use extreme care when approaching blind corners, doorways, shrubs, trees, or other objects that may obscure your vision of a child or bystander.
• Keep children, bystanders, helpers and pets at least 100 feet (30m) from the mower while it is in operation. Stop the machine if anyone enters the area.
• Never allow children under 14 years old to operate a power mower.
• Operators 14 years old and over should fully read and understand the operator’s manual and safety rules. Only responsible individuals who are familiar with these rules of safe operation should be allowed to use this machine.

GENERAL OPERATION

• Read this operator’s manual carefully in its entirety before assembling or operating this machine. Read, understand, and follow all instructions on the machine and in the manuals before operation. Familiarize yourself with the controls and proper use of this machine before operation.
• Save this manual for future and regular reference.
• Do not use the lawn mower for any job except that for which it is intended. Your lawn mower has been designed to perform only one job: cut grass.
• Never attempt to make a wheel height adjustment while the motor is running.
• Don’t force the lawn mower; it will do the job better and more safely at the rate for which it was designed.
• Don’t overreach, keep proper footing and balance at all times. Many injuries occur as a result of the mower being pulled over the foot during a fall caused by slipping or tripping. A slip and fall can cause serious personal injury. If you feel you are losing your footing, release the control handle immediately and the blade will stop rotating within three seconds.
• Thoroughly inspect the area where the mower is to be used and remove all stones, sticks, wires, dog bones, and other foreign objects.
• Prevent unintentional starting. Ensure the switch is in the off position before connecting to the battery pack, picking up or carrying the mower. Carrying the mower with your finger on the switch or energizing mower that has the switch on invites accidents.
• Never pull the mower back toward you while you are walking. If you must back the mower away from a wall or obstruction, first look down and behind you to avoid tripping, and then follow these steps:
• Step back from the mower in order to fully extend your arms.
• Be sure that you are well-balanced.
• Pull the mower back slowly.
• Remove the battery pack from the mower before making any adjustments, changing accessories, or storing appliance. Such preventive safety measures reduce the risk of starting the mower accidentally.
• Before and while moving backward with the mower, look behind and down for small children and other people.
• Do not operate the mower while under the influence of alcohol or drugs. Stay alert and watch what you are doing at all times. Use common sense and do not operate the lawn mower when you are tired.
• Always wear safety glasses or safety goggles during operation and while performing an adjustment or repair to protect your eyes. Thrown objects that ricochet can cause serious injury to the eyes. Always use a face or dust mask if the operation is dusty.
• Keep clear of the discharge opening at all times. Do not put hands or feet near rotating parts or under the cutting deck. Contact with the blade can amputate hands and feet.
• Plan your mowing pattern to avoid the discharge of material toward roads, sidewalks, bystanders, and the like. Also, avoid discharging material against walls or obstructions, which may cause discharged material to ricoche back toward the operator.
• To help avoid the blade or an injury from a thrown object, stay in the operator zone behind the handles.
• A missing or damaged discharge cover can cause blade contact or injuries from thrown objects.
• Objects struck by the lawn mower blade can cause severe injuries to persons. The lawn should always be carefully examined and cleared of all objects prior to each mowing.
• Stop the blade when crossing gravel drives, walks, or roads.
• Follow all charging instructions and do not charge the battery pack or mower 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.
• If lawn mower strikes a foreign object, follow these steps:
  • Release the bail switch to disengage the motor.
  • Remove the battery.
  • Inspect for damage.
  • Repair any damaged parts before restarting and operating the lawn mower.
• Have servicing performed by a qualified repair person using only identical replacement parts. This will ensure that the safety of the product is maintained.
• Dress properly; do not wear loose clothing or jewelry that can be caught in moving parts. Use of safety gloves and proper footwear is recommended when working outdoors. Wear sturdy, rough-soled work shoes and close-fitting slacks and shirts. Shirts and pants that cover the arms and legs and steel-toed shoes are recommended. Never operate this machine in bare feet, sandals, slippery or lightweight (e.g., canvas) shoes.
• Do not modify or attempt to repair the mower or the battery pack (as applicable) except as indicated in the instructions for use and care.
• Wear protective hair covering to contain long hair.
• Avoid dangerous environments; do not use the lawn mower in damp/wet locations or if it is raining.
• Store idle lawn mower indoors. When not in use, appliances should be stored indoors in dry, and high or locked-up place – out of reach of children. Always remove the battery from the mower before storing.
• Mow only in daylight or good artificial light. Walk, never run while operating.
• If the mower should start to vibrate abnormally, immediately stop the motor, remove the battery and check for the cause. Vibration is generally a warning that the mower is not functioning properly.
• Check bag frequently for deterioration and wear, and replace worn bags. Check that replacement bags comply with the original manufacturer’s recommendations or specifications.
• Before cleaning the mower, unclogging or removing the grass bag, mulching insert, or side discharge chute, turn the motor off and wait until the blade comes to a complete stop, then remove the battery pack. The cutting blade continues to rotate for a few seconds after the motor is shut off.
• Never perform these functions until you are sure the blade has stopped rotating.
• Keep cutting edges clean and sharp to ensure best performance.
• Periodically inspect safety devices and cords for damage. If damaged do not operate the unit until it has been repaired by an authorized service professional.
• Never operate the mower without the proper discharge cover, grass bag, mulching insert, side discharge chute, or other safety devices in place and working. Never operate the mower with damaged safety devices. Failure to do so can result in personal injury.
• Use only approved batteries and chargers. Non-approved batteries and chargers may cause damage to the mower or injure the operator.
• Do not dispose of the battery in a fire. The cells could catch fire or explode. Check with local codes and waste management for proper disposal instructions.
• 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.
• Do not open or destroy the battery. Electrolytes contained within the battery are corrosive and may cause damage to eyes or skin if released. It may be toxic if swallowed.
• 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 expose a battery pack or appliance to fire or excessive temperature. Exposure to fire or temperature above130°C may cause explosion.
• Exercise care in handling batteries to avoid shorting the battery with conducting materials such as rings, bracelets, keys, etc. The battery or conductor may overheat and cause burns if contact with said materials is made.
• 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.

SERVICE/MAINTENANCE

• Check the blade and the motor (machine) mounting bolts at frequent intervals for proper tightness.
• Replace the blade if it is bent or cracked. An unbalanced blade causes vibration that could damage the motor drive unit or cause personal injury.
• Keep all nuts, bolts, and screws tight in order to ensure the equipment is in safe working condition.
• Do not wash with a hose; avoid getting water in motor and electrical connections.
• Never remove or tamper with safety devices. Check their proper operation regularly. Never do anything to interfere with the intended function of a safety device or to reduce the protection provided by a safety device.
• Keep mower free of grass, leaves, or other debris build up. Allow mower to cool before storing.
• Never make any adjustments or repairs with the motor running.
• Always remove battery pack from mowers before adjusting, cleaning, or repairing.
• Check grass catcher components and the discharge guard frequently and replace with manufacturer’s recommended parts, when necessary.
• Sharpen a dull blade equally at each end to maintain the balance.
• Keep guards in place and in working order. Mower blades are sharp, and can cut. Wrap the blades or wear gloves, and use extra caution when servicing.
• Clean the blade thoroughly and check its balance by supporting it horizontally on a thin nail through its center hole. The nail should also 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.
• Use identical replacement blades only.
• Maintain lawn mower with care. Keep cutting edges sharp and clean for best and safest performance. Follow instructions for lubricating and changing accessories. Inspect lawn mower cord periodically and if damaged, have it repaired by an authorized service facility.
• If situations occur that are not covered in this manual, use care and good judgment or contact Customer Service for assistance.
• Never operate the mower without proper guards, plates, or other safety protective devices in place.

SLOPE OPERATION

• Slopes are a major factor related to slip-and-fall accidents, which can result in severe injury. Operation on slopes requires extra caution. If you feel uneasy on a slope, do not ow it.

Do:

• Mow across the face of slopes; never mow up and down.
• Exercise extreme caution when changing direction on slopes.
• Watch for holes, ruts, rocks, hidden objects, or bumps which can cause you to slip or trip. Tall grass can hide obstacles.

Do not:
