Safety Instructions
All Operators Must Read These Instructions Before Use
Always follow these safety guidelines. Failure to do so may result in serious bodily injury or death.
General Safety WARNINGS!
When using this cordless lawn mower, basic safety precautions should always be followed to reduce the risk of fire, electric shock, and personal injury. These precautions include:
WARNING! Do not operate without the entire grass catcher, discharge guard, rear guard, or other safety protective devices in place and in proper working order.
WARNING! The use of any other accessory or attachment might increase the risk of injury.
WARNING! To reduce the risk of injury, inspect the catcher assembly frequently and replace it with recommended replacement if there are signs of wear or deterioration.
Before using the mower, take the time to familiarize yourself with the controls, especially how to stop the mower in an emergency. The only individuals who should use the
mower are those who have a thorough understanding of the instructions and who know how to operate the machine.
Children should never be allowed access to the mower.
Retain this manual for future reference and reread it at the start of each mowing season.
WARNING! Contact with moving parts may cause entanglement, dismemberment, or another serious bodily injury. Always keep body parts (i.e. hands, feet) a safe distance away from moving parts. Ensure all covers and guards are securely in place before use.
Hot surfaces (i.e. the motor) may ignite flammable or combustible items and cause a fire or explosion, which can result in serious bodily injury. Keep the mower a safe distance away from flammable or combustible items until surfaces that are hot have completely cooled. Do not store the mower near flammable or combustible items.
A damaged blade or worn blade nut may break off the mower assembly and cause serious injury. Replace the damaged blade or blade nut before using the mower.

1. Avoid dangerous conditions – Do not use the mower in the rain or when the grass is damp or wet.

2. Keep children, bystanders, and pets away – Always keep children and spectators a safe distance away from the mower during operation and as the machine cools.

3. Dress properly – Always wear personal safety gear (i.e. glasses, rubber gloves, protective footwear, and dust masks) and proper clothing when using the mower. Loose clothing, long hair, or jewelry may get caught in the moving parts.

4. Use the right appliance – Do not use the lawnmower for any applications other than those for which it was intended.

5. Do not force the lawnmower – It will perform better with less likelihood of personal or mechanical injury if it is used at the rate for which it was designed.

6. Do not overreach – Keep proper footing and balance at all times.

7. Stay alert – Always be alert and watch what you are doing. Use common sense. Do not operate the lawnmower when you are tired or under the influence of alcohol or drugs.

8. Disconnect the lawnmower – Turn OFF and remove the safety key when the mower is not in use, before servicing it, when changing accessories and when performing any other maintenance task.

9. Store idle lawnmower indoors – When not in use, the lawnmower should be stored indoors in a dry, locked place out of the reach of children.

10. Maintain the lawnmower with care – Keep cutting edges sharp and clean for best and safest performance.

11. Use personal protective equipment. Always wear eye protection – Protective equipment such as safety glasses, a dust mask, non-skid safety shoes, a hard hat, and hearing protection, when used for appropriate conditions, will reduce the possibility of personal injuries.

12. Avoid unintentional starting – Ensure the switch is in the OFF position before inserting the safety key, or before picking up or carrying the tool. Carrying power tools with your finger on the switch or charging power tools with the switch ON can lead to accidents.

13. Remove any adjusting key or wrench before starting the power tool – A wrench or a key left attached to a rotating part of the power tool may result in personal injury.

14. Keep cutting blades sharp and clean – Properly maintained cutting blades with sharp edges are less likely to bind and are easier to control.

15. Keep all parts of the body away from the cutting blade – Do not remove cut material or hold material to be cut when blades are moving. Make sure the switch is off when clearing jammed material. A moment of inattention while operating the product may result in serious personal injury.

16. If the lawnmower strikes a foreign object, follow these steps:
    i) Stop the lawnmower by releasing the start/stop switch bar lever.
    ii) Remove the safety key.
    iii) Inspect for damage.
    iv) Repair any damage before restarting and operating the lawnmower.

17. Only use identical replacement blades and other genuine parts.

18. Keep guards in place and in proper working order.

Battery Charging
The battery in this lawnmower has been designed to provide maximum trouble- free life. However, like all batteries, it will eventually wear out. To obtain the longest possible battery life, we suggest the following:

• Store and charge your lawnmower in a cool area.
  Temperatures above or below normal room temperature will shorten battery life.

• Never store the lawnmower with the battery in a discharged condition. Recharge the unit immediately after it is discharged.

• All batteries gradually lose their charge. The higher the temperature is, the faster they lose their charge. If you store your lawnmower for long periods of time without using it, recharge the battery every 6 months. This will extend battery life.

NOTE: The lawnmower has been shipped in a low-charge condition and should be fully charged before use.

1. Plug the charger into an appropriate AC power outlet.
   Connect the charger plug into the charging socket of the lawnmower to start charging (Fig. 8).
   

2. The charge indicator LED on the charger will illuminate red to indicate that the charging is in progress (Fig. 8).

3. The battery will take approximately 4.5 hours to charge.
   The charge indicator LED will become green when the battery is fully charged, unplug the charger immediately when the green light is on.

CAUTION! This charger does not automatically turn off when the battery is fully charged. Please take care not to leave the lawnmower plugged into the charger. Switch off or unplug the charger at the mains when charging is complete.
NOTE: The charge indicator LED light will illuminate red when the charger is plugged in and is charging the lawnmower.
The light will turn green when the lawnmower is fully charged.
The charging process starts as soon as the charger is plugged into both the proper electrical outlet and the tool.

• During the charging procedure,  the housing of the tool will feel slightly warm to the touch.  This is normal.
• When no further use is planned for an extended period of time, disconnect the battery charger from the outlet and the unit.
• Do not use the tool during the charging procedure.

7. Insert the safety key into the slot and resume normal use.

Mowing Tips
W ARNING! Inspect the area prior to mowing and remove all the stones, sticks, wires, and other foreign objects that could be picked up and thrown by the rotating blade.
Failure to comply not only will damage the mower blade but can also lead to serious personal injury.

• Be sure to check the mowing blade periodically for signs of wear and sharpen it at least once per year, as described in the maintenance section.
  NOTE: A sharp blade will greatly enhance the performance of the mower, especially when cutting tall blades of grass.

• When cutting thick grass,  reduce your walking speed in order to allow for a more effective cut and a proper discharge of the clippings. For a healthy lawn, always cut off one-third or less from the total length of the grass.
  The average lawn should be approximately 1.5 in. to 2 in.(3.8 cm to 5 cm) long during cool months,  and more than 2 in. (5 cm) long during hot months.  If there is growth, the lawn should be cut in the fall.

• The lawn will look better if it is always cut to the same height and in alternate directions.

• When crossing any graveled surfaces, release the switch bar lever to turn off the mower. The stones can be picked up and thrown by the rotating blade.

• Set the mower to the highest cutting height when mowing on uneven ground or in tall weeds.
  W ARNING! If you strike a foreign object, stop the motor and remove the safety key. Thoroughly inspect the mower and repair any damage before resuming work.

• IMPORTANT! Never open the ejector flap when the grass collection bag has been detached (to be emptied) and the motor is still running. A rotating blade can cause serious injuries!

• Always carefully fasten the ejector flap and grass collection bag.  Switch off the motor before emptying the grass collection bag. Always ensure that a safe distance (provided by the length of the long handles) is maintained between the user and the mower housing. Be especially careful when mowing and changing direction on slopes and inclines.

• Maintain a solid footing and wear sturdy, non-slip footwear and long trousers. Always mow across an incline (not up and down).

• For safety reasons, the lawnmower may not be used to mow inclines with gradients exceeding 15 degrees.

• Use special caution when backing up and pulling the lawnmower towards you as such maneuvering of the machine poses a tripping hazard.

Maintenance + Care

W ARNING! Before cleaning, repairing, or inspecting the mower, disconnect the power supply by plugging out the safety key, and verifying that all moving parts have come to a complete stop.
General

• Always keep the mower clean and free of grass,  dirt, or other debris.
• Keep the handles dry, clean, and free of oil and grease.
• After each cutting session, remove accumulated grass clippings and debris using either a dry cloth or a hand brush. You may also clean the equipment with a damp cloth and some soft, non-abrasive soap. Do not use cleaning agents or harsh solvents as they may damage the equipment’s plastic components. Make sure that no water penetrates the equipment’s interior as intake of water can destroy the switch/plug mechanism and the electric motor.
• Do not clean the lawnmower with running water, particularly with high-pressure water.
• Check all nuts, bolts, and screws for proper tightness before each use.
• Frequently inspect the grass collection bag assembly for signs of wear and replace immediately with a genuine Snow Joe®  + Sun Joe®  part if the damage is found.
• Replace excessively worn or damaged parts immediately.
• To maximize your mower’s longevity, all screwed parts, including the wheels and axles, should be cleaned and lubricated. There are no parts inside the equipment which require additional maintenance or lubrication.

Blade Maintenance
IMPORTANT: The mower blade is sharp and can cause severe personal injury if handled incorrectly. Wrap the blade or wear protective gloves, and use extra caution when handling.
