When a 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 pack terminals together may cause sparks, burns, fire or explosion.
Do not place battery products or their batteries near fire or heat. This increases the risk of explosion and possibly injury.
Do not open or mutilate the battery pack. Released electrolyte is corrosive and may cause damage to the eyes or skin. It may be toxic if swallowed.
Protect the battery pack against moisture and water. Do not charge the product in a damp location. Following this rule will reduce the risk of electric shock.
In case of damage and improper use of the battery, vapor may be emitted. Provide for fresh air, and seek medical help in case of complaints. The vapour can irritate the respiratory system.
Do not leave the battery pack inside a vehicle in hot or cold conditions.
Do not incinerate the battery.
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.

LAWN MOWER SAFETY WARNINGS

Before use, always visually inspect to ensure blades, blade bolts, and cutter assembly are not worn or damaged.
Replace worn or damaged blades and bolts in sets to preserve balance.
The blade on the product is sharp. Use extreme caution and wear heavy-duty gloves when fitting, replacing, cleaning or checking bolt security.
Bring the product to an authorized service center to replace damaged or unreadable labels.
Check all nuts, bolts, and screws at frequent intervals for proper tightness to be sure that the product is in safe working condition.
Frequently check the grass catcher for wear, holes, or deterioration.
Replace worn or damaged parts before operating the product.
The product must be started with the user behind the handlebars in the operator safety zone. Never start the product if:
- Not all four wheels are on the ground.
- The grass discharge chute is exposed and is not protected by the grass catcher and grass discharge chute cover.
- The hands and feet of all persons are not clear of the cutting enclosure.
Never operate the product if the on/off switch on the handlebar does not properly start and stop the product.
Never attempt to lock the on/off switches in the on position; this is extremely dangerous.
Do not force the product. It will do the job better and safer at the speed for which it was designed.
Stop the blade when crossing gravel surfaces.
Do not pull the product backward unless necessary. If you must back the product away from a wall or obstruction, first look down and behind to avoid tripping or pulling the product over your feet.
Stop the motor and allow the blade to stop if the product has to be tilted for transportation when crossing surfaces other than grass, and when transporting the product to and from the work area.
Never use the product with defective guards or shields, or without safety devices, such as, deflectors and/ or grass collectors, in place.
Do not tilt the product when turning on the motor or while the motor is running. If absolutely necessary, you may raise the front of the lawn mower by no more than 5 cm to enable easier starting. Press down on the handlebar to achieve this. Always return the mower to its normal position with all wheels on the ground before cutting. Tilting the mower exposes the blade and increases the probability of objects being thrown and accidental contact with the blade.
Turn on the motor carefully according to instructions and keep hands and feet away from blades. Do not put hands or feet near or under rotating parts.
Never pick up or carry the product while it is running.
Turn off the product, and remove the isolator key and the battery pack. Make sure that all moving parts have come to a complete stop:

- before clearing blockages or unclogging discharge chute
- before checking, cleaning, or working on the product
- before removing the grass catcher or opening the grass discharge chute cover
- after striking a foreign object; inspect the product for damage and make repairs as necessary before restarting and operating the product
- If the product starts to vibrate abnormally (check immediately)
- inspect for damage, particularly the blades
- replace or repair any damaged parts
- check for and tighten any loose parts
Avoid holes, ruts, bumps, rocks, property stakes, or other hidden objects. Uneven terrain could cause a slip-and-fall accident.
Always ensure that the motor control cable is never trapped, pinched or otherwise damaged during assembly or when folding the handle.

ADDITIONAL BATTERY SAFETY WARNINGS

WARNING: To reduce the risk of fire, personal injury, and product damage due to a short circuit, never immerse your tool, battery pack or charger in fluid or allow a fluid to flow inside them. Corrosive or conductive fluids, such as seawater, certain industrial chemicals, and bleach or bleach- containing products, etc., can cause a short circuit.

PRODUCT FEATURES
OVERLOAD AND OVERHEAT PROTECTION

The product has an overload protection device. When overloading is detected, the product will automatically turn off. If the overload protector is actuated, the on/off button must be released. Press the on/off button to restart the product.
The battery pack has overheat protection. Excessive temperatures will cause the battery to stop powering the product. If the battery pack is too warm, allow it to cool down before resuming operation. If the product still does not work, recharge the battery.

NOTE: The latch should snap into place when the battery pack is properly inserted into the product.

GENERAL MOWING TIPS

The run time of the battery depends on the condition, length, and density of the grass.
Adjust the cutting height of the lawn mower to suit the current condition of the lawn.
For best performance, always cut off one-third or less of the total height of the grass.
When cutting long 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 collection or discharge of grass clippings.
New or thick grass may require a higher cutting height.
To collect the grass cuttings for disposal, remove the mulching plug and fit the grass catcher, making sure that the grass discharge chute cover is properly closed. Empty the grass catcher regularly; otherwise, the discharge chute will become blocked with grass cuttings.
If you are making a light cut and wish for the grass cuttings to remain on the lawn, fit the mulching plug and close the grass discharge chute cover to cover the discharge opening. It is not necessary to fit the grass catcher in this case.
The product is designed to operate and cut most effectively when moving forwards.
A higher cutting height extends the run time of the battery.

RISK REDUCTION
It has been reported that vibrations from handheld tools may contribute to a condition called Raynaud’s Syndrome. Symptoms may include tingling, numbness and blanching of the fingers, usually apparent upon exposure to cold. Hereditary factors, exposure to cold and dampness, diet, smoking and work practices are all thought to contribute to the development of these symptoms. There are measures that can be taken by the operator to possibly reduce the effects of vibration:

Keep your body warm in cold weather. When operating the product, wear gloves to keep the hands and wrists warm. It is reported that cold weather is a major factor contributing to Raynaud’s Syndrome.
After each period of operation, exercise to increase blood circulation.
Take frequent work breaks. Limit the amount of exposure per day.

If you experience any of the symptoms of this condition, immediately discontinue use and see your physician.

WARNING: Injuries may be caused, or aggravated, by prolonged use of a tool. When using any tool for prolonged periods, ensure you take regular breaks.

The declared vibration value has been measured with a standard test method and may be used to compare one tool with another.
The declared vibration value may be used in a preliminary assessment of exposure.
The vibration emission during the actual use of the power tool can differ from the declared total value depending on how the tool is used.
Identify safety measures to protect the operator based on an estimation of exposure in the actual conditions of use, taking account of all parts of the operating cycle such as the times when the tool is switched off and when it is running idle in addition to the trigger time.
