WARNING! The inside of the mufﬂer contain chemicals that may be carcinogenic. Avoid contact with these elements in the event of a damaged mufﬂer.

Checking, maintaining and servicing the machine

′′′′s safety

equipment

WARNING! Overexposure to vibration can lead to circulatory damage or nerve

damage in people who have impaired circulation. Contact your doctor if you experience symptoms of overexposure to vibration. Such symptoms include numbness, loss of feeling, tingling, pricking, pain, loss of strength, changes in skin colour or condition. These symptoms normally appear in the ﬁngers, hands or wrists. The risk increases at low temperatures.

Mufﬂ er

The mufﬂer is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user.

In countries that have a warm and dry climate there is a signiﬁcant risk of ﬁre. Consequently, we have equipped the mufﬂer with a spark arrestor screen mounted inside the mufﬂer.

For mufﬂers it is very important that you follow the instructions on checking, maintaining and servicing your machine. See instructions under the heading Checking, maintaining and servicing the machine’s safety equipment.

WARNING! All servicing and repair work on the machine requires special training. This is especially true of the machine safety equipment. If your machine fails any of the checks described below you must contact your service agent. When you buy any of our products we guarantee the availability of professional repairs and service. If the retailer who sells your machine is not a servicing dealer, ask him for the address of your nearest service agent.

Stop switch

• Check that the vibration damping element is undamaged and securely attached.

Mufﬂer

• Never use a machine that has a faulty mufﬂer.

• Regularly check that the mufﬂer is securely attached to the machine.

• The mufﬂer on your machine is equipped with a spark arrestor screen. NOTE: THE SPARK ARRESTOR SCREEN ON THIS UNIT IS NOT SERVICEABLE. As your unit is used, carbon deposits build up on the mufﬂer and spark arresting screen. For normal homeowner use, however, the mufﬂer and spark arresting screen will not require any service. After 50 hours of use, we recommend that your mufﬂer be serviced or replaced by your authorized service

WARNING! Never use a machine with faulty safety equipment. The machine’s safety equipment must be checked and maintained as described in this section. If your machine fails any of these checks contact your service agent to get it repaired.

Air ﬁlter

Never use the leaf blower without an air ﬁlter or with a damaged or deformed ﬁlter element as unﬁltered, dusty air can quickly destroy the engine.

General working instructions

IMPORTANT! This section considers basic safety rules when working with blowers. If you encounter a situation where you are uncertain how to proceed you should ask an expert. Contact your dealer or your service workshop. Avoid all usage which you consider to be beyond your capability.

Show consideration to persons in your surroundings by avoiding using the machine at unsuitable times, such as late in the evening or early in the morning. To reduce sound levels, limit the number of pieces of equipment used at any one time. Read through and follow the simple directions so that you disturb your surroundings as little as possible.

• Use the blower with the lowest possible throttle. It is seldom necessary to use full throttle, and many work procedures can be done at half throttle. A lower throttle means less noise and less dust, and it is also easier to keep control over the rubbish collected together/moved.

• Use a rake or a brush to release rubbish stuck to the ground.

• Hold the opening of the blower as close to the ground as possible. Utilise the entire length of the blow pipe to keep the air current close to the ground.

• Clean up afterwards. Make sure that you have not blown rubbish into someone’s garden.

• Operate power equipment only at reasonable hours, not early in the morning or late at night when people might be disturbed. Comply with times listed in local ordinances.

WARNING! Be aware of your surroundings. If anyone approaches your work area, set the throttle control to the lowest throttle until the person is at a safe distance. Direct the blower away from people, animals, play areas, open windows and cars etc.

SAFETY INSTRUCTIONS

Basic safety rules

Z 87

• No unauthorised persons or animals may be present in the working area, which is 15 metres.

• Allow the engine to cool before refueling.

• Keep all parts of your body away from hot surfaces.

• If the machine catches ﬁre or other emergency occurs which forces you to release yourself from the machine, open the harness straps and let the machine fall backwards.

• The powerful currents of air can move objects at such a speed that they can bounce back and cause serious eye injuries.

• Never put the machine down with the engine running unless you have it in clear sight.

• Engine exhaust fumes contain carbon monoxide, which can cause carbon monoxide poisoning. For this reason you should not start or run the machine indoors, or anywhere that is poorly ventilated.

• The operator’s manual should warn that work from ladders or high places (such as roofs) is prohibited and could result in severe injury.

• CAUTION! Do not use the machine unless you are able to call for help in the event of an accident.

Basic working techniques

• Do not direct the air jet towards people or animals.

• Stop the engine before assembling or dismantling accessories or other parts.

• Do not use the machine in bad weather, such as dense fog, heavy rain, strong wind, intense cold, etc. Working in bad weather is tiring and can lead to dangerous conditions, e.g. slippery surfaces.

• Minimise the blowing time by lightly wetting dusty areas or using spray equipment.

• Make sure you can move and stand safely. Check the area around you for possible obstacles (roots, rocks, branches, ditches, etc.) in case you have to move suddenly. Take great care when working on sloping ground.

10 – English

WARNING! Watch out for thrown objects. Always wear eye protection. Stones, rubbish, etc. can be thrown up into the eyes causing blindness or serious injury. Keep unauthorised persons at a distance. Children, animals, onlookers and helpers should be kept outside the safety zone of 15 m. Stop the machine immediately if anyone approaches.

WARNING! Don’t operate the blower if the exhaust gas outlet on the engine cover is covered by a wall and/or some other obstacles, the machine could get damage. Make sure that the distance is 50 cm or more from the obstacles during operation.

WARNING! Always stop the engine before cleaning.

• This blower is a backpack type, and is carried using a shoulder harness while operating. It is operated and controlled with the handle on the tube using the right hand.

• The speed of the air jet is regulated by means of the throttle. Select the speed best suited for respective tasks.

SAFETY INSTRUCTIONS

To avoid holding your ﬁnger on the throttle all the time when using the blower, the required throttle can be set with the cruise control (D). Full throttle is obtained when the throttle trigger is pushed in or the cruise control is pushed down fully.

• Check that the air intake is not blocked, for example, by leaves or rubbish. A clogged air intake reduces the machine’s blowing capacity and increases the engine’s working temperature, which can result in engine failure. Stop the engine and remove the object.

• Be aware of the wind direction. Work with the wind to make your work easier.

• Using the blower to move large piles is time consuming and creates unnecessary noise.

• Keep a good balance and a ﬁrm foothold.

• When work is ﬁnished the machine should be stored vertically.

FUEL HANDLING

Fuel

CAUTION! The machine is equipped with a two-stroke engine and must always be run using a mixture of gasoline and two-stroke engine oil. It is important to accurately measure the amount of oil to be mixed to ensure that the correct mixture is obtained. When mixing small amounts of fuel, even small inaccuracies can drastically affect the ratio of the mixture.

WARNING! Always ensure there is adequate ventilation when handling fuel.

Gasoline

CAUTION! Always use high grade oil mixed gasoline (minimum 87 RON).

• This engine is certiﬁed to operate on unleaded

gasoline.

• The lowest recommended octane rating is 87. If you run the engine on lower octane rating than 87 socalled “knocking“ can occur. This leads to an increased engine temperature, which can result in a serious engine breakdown.

• When working at continuous high revs a higher octane rating is recommended. Use good quality unleaded gasoline.

Ethanol blended fuel, E10 may be used (max 10% ethanol blend). Using ethanol blends higher than E10 will create lean running condition which can cause engine damage.

Two-stroke oil

• For best results and performance, use a good quality fully sythetic air cooled two stroke oil at a mixture of 1:50 (2%)

• Never use two-stroke oil intended for water-cooled outboard engines, sometimes referred to as outboard oil.

• Never use oil intended for four-stroke engines.
