SYMBOLS AND DECALS

Decal 6 Seed application chart

Values are approximate; quantities of seed depend on the speed at which the machine is run. Faster running speed results in sparser sowing.

Preparing the lawn

• Cut the grass to approximately 1/2" lower than you normally would.

• Do not water before sowing.

• Remove the layer of old grass cuttings (thatch).

• Aerate the lawn with a ground aerator of the coring type.

• Fertilize the lawn.

Seed application recommendations

• For best results, sow in two directions with a 45° angle between.

• Water generously immediately afterward and continue watering moderately for 10–14 days to keep the soil moist.

• After germination, water sporadically to encourage root growth.

Decal 7 Warning

Engine exhaust, some of its constituents and certain vehicle components contain or emit chemicals considered by the State of California to cause cancer, birth defects or other reproductive harm. The engine emits carbon monoxide, which is a colorless, poisonous gas. Do not use the machine in enclosed spaces.

Decal 9 Important information

Read and make sure you understand the Operator’s Manual before use or maintenance.

To obtain a replacement manual, please contact your dealer.

Observe all safety instructions; otherwise you may injure yourself or others around you.

Make sure that the machine is in serviceable condition prior to use.

Make sure that all protective devices are in place when the machine is in use.

Stop the engine and wait until all machine movement comes to a standstill before service, adjustment or cleaning.

Do not run the engine in poorly ventilated spaces. Make sure nobody is in the vicinity of the machine

before starting and during use. Avoid slopes that are too steep to use the machine

safely. Clear any debris from the lawn prior to use.

SAFETY INSTRUCTIONS

General use

The object of this manual is to help you use your Husqvarna machine safely and to give you information about how to maintain your machine. Please read the manual carefully before attempting to use the machine.

If after reading the operator’s manual you are still unsure about the safety risks associated with use of the machine, you should not use the machine. Please contact your dealer for more information.

These safety instructions only address the basics for safe use. It would be impossible in the safety instructions to describe all possible risk situations that could arise when using the machine. You can, however, prevent accidents by always using common sense.

To obtain extra copies of the operator’s manual, please contact your dealer.

WARNING!

Under no circumstances may the original design of the machine be modified without written approval from the manufacturer. Such modifications not only affect the performance and durability of the machine but may even pose a safety risk for users and those in the vicinity. Unauthorized modifications to the design of the machine may absolve the manufacturer from liability for any resulting personal injury or property damage. Modifying the machine without written approval from the manufacturer may void the guarantee.

IMPORTANT INFORMATION Do not use the machine until you have read

the operator’s manual carefully and understand the instructions given. All maintenance work or adjustments not described in this manual must be performed by an authorized Husqvarna service workshop.

• Read this manual carefully and make sure you understand it before using the machine or performing any maintenance. If the user cannot read this manual, it is the responsibility of the machine owner to explain the contents to the user.

SAFETY INSTRUCTIONS

• Never allow children or persons not trained in the use of the machine to use or service it. Local laws may regulate the age of the user.

• People and animals can distract you causing you to lose control of the machine. For this reason, you should always concentrate and focus on the task at hand.

The engine can become very hot. To avoid being burned, you must turn off the engine and wait until all parts have cooled before touching the engine.

WARNING!

Overexposure to vibration may lead to circulatory or nerve damage, particularly in people who have impaired circulation. Contact your doctor if you experience symptoms that could have been caused by overexposure to vibration. Examples of common symptoms include numbness, pain, muscle weakness, change of skin color or an uncomfortable feeling of tingling. These symptoms appear most frequently in the fingers, hands or wrists.

• Clear the area of objects such as stones, toys, steel wire, etc. that could become caught in moving machine parts and thrown out.

• Find and locate all fixed objects in the ground, such as sprinkler systems, poles, water valves, bases for washing lines, etc. Be certain to check for hidden electrical cables or similar in the surface of the lawn. Always run the machine around these objects. Never intentionally run the machine over foreign objects.

• Make sure all guard plates and protective shields are in place and intact when using the machine.

• Makes sure no clothing, long hair or jewelry can catch in moving machine parts.

• Never use the machine when barefoot. Always wear protective shoes or protective boots with anti-slip and preferably with steel toes.

• Wear approved ear-protection when running the machine. Ask your dealer about approved ear-protection.

WARNING!

Always use approved protective clothing and approved protective equipment when using the machine. Protective clothing and protective equipment cannot eliminate the risk of accidents, but wearing proper clothing and the correct equipment will reduce the degree of injury should an accident occur. Ask your dealer about approved protective clothing and approved protective equipment recommended by Husqvarna.

SAFETY INSTRUCTIONS

Operating

• Do not use the machine on grades of more than 20°. We recommend working across slopes rather than up and down. This will yield a more even result. Do not leave the machine standing on a slope unattended.

• Do not use the machine if you are tired, if you have consumed alcohol, or if you are taking other drugs or medication that can affect your vision, judgment or co-ordination.

• Never use the machine indoors or in spaces lacking proper ventilation.

WARNING!

Engine exhaust, some of its constituents and certain vehicle components contain or emit chemicals considered to cause cancer, birth defects or other reproductive harm. The engine emits carbon monoxide, which is a colorless, poisonous gas. Do not use the machine in enclosed spaces.

• Do not use the machine on any surface other than grass.

• Make sure you have a proper foothold when using the machine, particularly when backing. Walk, don’t run. Never work on wet grass. Poor traction may cause you to slip.

• Keep your hands and feet away from moving parts.

• Keep your hands and feet away from the work tools.

• Slow down and be especially careful on slopes. Make sure to run the machine in the recommended direction on slopes. Be careful when working close to sudden changes in level.

• Smoking, open flames or sparks in the vicinity of the machine are strictly forbidden. Gasoline is extremely flammable and carelessness in handling can result in personal injury or fire.

• Stop and inspect the equipment if you run over or into anything. If necessary, make repairs before beginning again.

• Whatever happens, you should always park the machine on even ground, disengage the drive, turn off the engine and wait until all moving parts have stopped before leaving the operating position behind the machine.

Movement/Transport

• To turn and steer the machine, press down on the handle and turn on the back wheels.

• Turn off the engine and allow it to cool at least 2 minutes before transport.

• Collapse the handle if the machine is equipped with a collapsible handle.

• Be careful and use safe lifting and moving techniques when loading/unloading the machine.

• We recommend having two people to lift the machine.

• Fasten the machine properly in place with approved fasteners, such as tension belts, chains or rope. Always check that you are in compliance with applicable traffic regulations before transporting the machine.

Storage

• Allow the engine to cool before storing the machine. Never store the machine near a open flame.

• Store the machine with the fuel valve closed.

• Store the machine and fuel in such a way that there is no risk that leaking fuel or fumes can come in contact with flames or sparks from electrical machines, electric engines, relays, switches, boilers or similar.
