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 lawn mower 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 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 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 cutting area. Keep clear of the discharge opening at all times.

• Operate the lawn mower 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 face mask if operation is dusty.

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

• Do not force the lawn mower – 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 lawn mower. Do not operate the mower while tired, upset, or under the influence of drugs, alcohol, or medication. A moment of inattention while operating the lawn mower may result in serious personal injury.

• Maintain lawn mower with care – Keep machine in good working condition. Keep blades sharp and guards in place and in working order. Replace damaged or unevenly  worn blades before using 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. 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 lawn mower, removing the grass catcher, or removing the mulching plug.

• Maintain lawn mower with care – Keep machine in good working condition. Keep blades sharp and guards in place and in working order. Replace damaged or unevenly worn blades before using 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. 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 lawn mower, removing the grass catcher, or removing the mulching plug.

• Never use a hose, water, or any liquids to clean or rinse off the lawn mower. Corrosive liquids, water, fertilizers, and chemicals used to treat lawns can enter the lawn mower 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 blade if it is bent or cracked. An unbalanced blade causes 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 of 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 battery pack, picking up or carrying the appliance. Carrying the appliance with your finger on the switch or energizing appliance that have the switch on invites accidents.

• 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.

• 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 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 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.

• If the lawn mower strikes a foreign object, follow these steps:
  • Stop the lawn mower by releasing the blade control lever, wait until the blade comes to a complete stop, and then remove 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 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 original manufacturer’s recommendations and specifications.

NOTE:** Fully charge battery before each use for optimal runtime.

• Make sure the lawn is clear of stones, tree nuts, sticks, wires, and other objects that could damage the lawn mower blades or motor. Do not mow over property stakes or  other metal posts. Such objects could damage the blade or be accidentally thrown by the mower in any direction and cause serious personal injury to the operator and others.
•  For a healthy lawn, always cut off one-third or less of the total length of the grass.
• When cutting heavy grass, reduce walking speed to allow for more effective cutting and a proper discharge of the clippings.
• Do not cut wet grass. It will stick to the underside of the deck and prevent proper bagging or mulching of grass clippings.
• New or thick grass may require a narrower cut or a higher cutting height.
• Clean the underside of the mower deck after each use to remove grass clippings, leaves, dirt, and any other accumulated debris.
  NOTE: Always stop mower, allow blades to completely stop, remove the start key and remove the battery pack from the battery port before cleaning underneath the mower.

SLOPE OPERATION
See Figure 13.

WARNING:
Slopes are a major factor related to slip and fall accidents that can result in severe injury. Operation on slopes requires extra caution. If you feel uneasy on a slope, do not mow it. For your safety, do not attempt to mow slopes greater than 15 degrees and mow across the face of slopes, not up and down.

• Mow across the face of slopes, not 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. Remove all objects such as rocks, tree limbs, etc.,  which could be tripped over or thrown by the blade.
•  Always be sure of your footing. A slip and fall can cause serious personal injury. If you feel you are losing your balance, release the upper blade control lever immediately.
• Do not mow near drop-offs, ditches, or embankments; you could lose your footing or balance.
