General safety instructions
WARNING: Read the warning instructions that follow before you use the product.

• This product is dangerous if used incorrectly or if you are not careful. Injury or death can occur if you do not obey the safety instructions.

• This product produces an electromagnetic field during operation. This field may under some circumstances interfere with active or passive medical implants. To reduce
  the risk of serious or fatal injury we recommend persons with medical implants to consult their physician and the medical implant manufacturer before operating this product.

• Always be careful and use your common sense. If you are not sure how to operate the product in a special situation, stop and speak to your Husqvarna dealer before you continue.

• Keep in mind that the operator will be held responsible for accidents that involve other persons or their property.

• Keep the product clean. Make sure that you can clearly read signs and decals.

• Always monitor a person, with decreased physical capacity or mental capacity, that uses the product. A responsible adult must be there at all times.

• Do not use the product if you are tired, ill, or under the influence of alcohol, drugs or medicine. This has a negative effect on your vision, alertness, coordination and
  judgment.

• Do not use the product if it is defective.

• Do not change this product or use it if it is possible that it has been changed by others.

Work area safety
WARNING: Read the warning instructions that follow before you use the product.

• Remove objects such as branches, twigs and stones from the work area before you use the product.

• Objects that hit against the cutting equipment can eject and cause damage to persons and objects. Keep bystanders and animals at a safe distance from the product.

• Never use the product in bad weather such as fog, rain, strong winds, intense cold and risk of lightning. To use the product in bad weather or in moist or wet locations is
  tiring. Bad weather can cause dangerous conditions, such as slippery surfaces.

• Look out for persons, objects and situations that can prevent safe operation of the product.

• Look out for obstacles, such as roots, stones, twigs, pits and ditches. Long grass can hide obstacles.

• To cut grass on slopes can be dangerous. Do not mow excessively steep slopes. Do not use the product on ground that slopes more than 15°

• Exercise extreme caution when changing direction on slopes. Operate the product across the face of slopes. Do not move up and down.

Work safety
WARNING: Read the warning instructions that follow before you use the product.

• Use this product to cut grass lawns only. It is not permitted to use it for other tasks.

• Use personal protective equipment. Refer to Personal protective equipment on page 12.

• Make sure that you know how to stop the motor quickly in an emergency.

• Do not operate the product in rain or wet conditions. The risk of electrical shock increases if water enters the product.

• Do not operate the product unless the blade and all covers are attached correctly. An incorrectly attached blade can come loose and cause personal injury.

• Make sure that the blade does not hit objects such as stones and roots. This can do damage to the blade and bend the motor shaft. A bent axle causes heavy vibration and a very high risk that the blade becomes loose.

• If the blade hits an object or if vibrations occur, stop the product immediately. Stop the motor, pull up the safety key and remove the battery. Examine the product for
  damages. Repair damages or let an authorised service agent do the repair.

• Never attach the motor brake handle permanently to the handle when the motor is started.

• Put the product on a stable, flat surface and start it. Make sure that the blade does not hit the ground or other objects.

• Always stay behind the product when you operate it.

• Let all the wheels stay on the ground and keep 2 hands on the handle when you operate the product. Keep your hands and feet away from the rotating blades.

• Do not tilt the product when the motor is started.

• Be careful when you pull the product rearward.

• Never lift up the product when the motor is started. If you must lift the product, first stop  the motor, pull up the safetykey and remove the battery.

• Do not walk rearward when you operate the product.

• Stop the motor when you move across areas without grass, for example paths made of gravel, stone and asphalt.

• Do not run with the product when the motor is started. Always walk when you operate the product.

• Stop the motor before you change the cutting height. Never make adjustments with the motor started.

• Never let the product stay out of view with the motor started. Stop the motor and make sure that the cutting equipment does not rotate. Safety instructions for operation
  Personal protective equipment
  WARNING: Read the warning instructions that follow before you use the product.

• Personal protective equipment cannot fully prevent injury but it decreases the degree of injury if an accident does occur. Let your dealer help you select the right equipment.

• Use heavy-duty slip-resistant boots or shoes. Do not use open shoes or go with bare feet.

• Use heavy, long pants.

• Use protective gloves when necessary, for example when you attach, examine or clean the cutting equipment.

2. Push the SavE button again to stop the function. The SavE symbol (B) on the display goes out. (Fig. 37)
   The SavE function stops automatically if the ground conditions make it necessary to have a higher output.
   The SavE function starts automatically again when the ground conditions let it.

PowerBoost function
When the product cuts long or wet grass, the motor automatically increases rpm. To save battery time, the motor goes back to standard mode automatically when the PowerBoost function is not necessary.
Motor stalling
During operation, the blade and motor can temporarily stop because of obstacles such as grass blockage below the cutting cover. If this occurs and you keep the motor brake handle pushed down, the product restarts automatically. If the product does not restart in 5-10 seconds, it can be necessary to clean below the cutting cover. Refer to To clean the product on page 20.
WARNING: If the motor stops, the product tries to restart automatically for 5-10 seconds. Wait for a minimum of 15 seconds before you do a check of the cutting cover.
WARNING: Before a check of the cutting cover, release the motor brake handle, turn the safety key to 0, remove the battery and wait for a minimum of 5 seconds. There is a risk of injury if the obstacle is removed and the product accidentally starts.
To stop the product
The product stops automatically if you do not operate it for 3 minutes.

1. Release the motor brake handle to stop the motor. (Fig. 19)
2. Push the ON/OFF button on the control panel. All LED lights and symbols on the display go out. (Fig. 38)
3. Remove the safety key from the safety lock and put it in the safety key holder.

To get a good result

• Always use a sharp blade. A blunt blade gives an irregular result and the cut surface of the grass becomes yellow. A sharp blade also uses less energy than a blunt blade.
• Do not cut more than ⅓ of the length of the grass. Cut first with the cutting height set high. Examine the result and lower the cutting height to an applicable level. If the grass is very long, drive slowly and cut 2 times if necessary.
• Cut in different directions each time to prevent stripes in the lawn.
• Keep the cutting cover clean. Buildup from grass and dirt on the inner side of the cutting cover can decrease the cutting result. Refer to To clean the product on page 20.
