English


1. Refrain from operating the blower if you are tired, ill, or upset, or if you are under the influence of alcohol, drugs or medication

2. To reduce the risk of hearing loss associated with sound levels, hearing protection is required.

3. To reduce the risk of injury associated with thrown objects, always wear eye protection and foot protection. Approved protective goggles must comply with standard

ANSI Z87.1 in the USA or EN 166 in EU countries.

4. To reduce the risk of injury associated with the inhalation of dust, use a face filter mask in dusty conditions.

5. Wear rubber-soled shoes or shoes with some other form of anti-slip protection to help protect you against falling.

6. To reduce the risk of injury associated with objects being drawn into rotating parts, do not wear loose clothing, scarves, neck chains, hair longer than shoulder length, or other loose material.

7. Prolonged use of a blower, exposing the operator to vibrations and cold, may produce whitefinger disease (Raynaud’s phenomenon), the symptoms of which include tingling and burning sensations followed by loss of color and numbness in the fingers. All factors which contribute to whitefinger disease are not known, but cold weather, smoking diseases or physical conditions as well as long periods of exposure to vibration are mentioned as factors. In order to reduce the risk of whitefinger disease, the following precautions are strongly recommended a) Keep your body warm. Never use the blower during rain.

b) Take more than 5 minutes of break in a warm place frequently.

c) Maintain a firm grip at all times, but do not squeeze the handles with constant, excessive pressure.

d) If you feel discomfort, redness and swelling of your fingers or any other part of your body, see a doctor before it gets worse.

8. The ignition system of your unit produces an electromagnetic field of a very low intensity. This field may interfere with some pacemakers. To reduce the risk of serious or fatal injury, people with pacemaker should consult their physician and the pacemaker manufacturer before operating this tool.

WORKING CIRCUMSTANCE

1. To reduce the risk of injury associated with exhaust fume inhalation, do not operate in unventilated area. The exhaust gases contain harmful carbon monoxide.

FUEL

WARNING

- Gasoline is very flammable.

Avoid smoking or bringing any flame or sparks near fuel. Make sure to stop the engine and allow it cool before refueling the unit.

Select outdoor bare ground for fueling and move at least

10ft (3m) away from the fueling point before starting the engine.

- The engines are lubricated by oil specially formulated for air-cooled 2-cycle gasoline engine use. If

Husqvarna oil is not available, use an antioxidant added quality oil expressly labeled for aircooled 2-cycle engine use.

(JASO FC GRADE OIL or ISO

EGC GRADE)

- Do not use BIA or TCW (2stroke water-cooling type) mixed oil.

RECOMMENDED MIXING RATIO

GASOLINE 50:OIL 1

- Exhaust emission are controlled by the fundamental engine parameters and components (i.e., carburation, ignition timing and port timing) without addition of any major hardware or the introduction of an inert material during combustion.

- These engines are certified to operate on unleaded gasoline.

- Make sure to use gasoline with a minimum octane number of 89 RON (USA/Canada: 87AL)

- If you use a gasoline of a lower octane value than specified, there is a danger that the engine temperature may rise and an engine problem such as piston seizing may consequently occur.

- Unleaded gasoline is recommended to reduce the contamination of the air for the sake of your health and the environment.

- Poor quality gasolines or oils may damage sealing rings, fuel lines or fuel tank of the engine.

■

HOW TO MIX FUEL

IMPORTANT

Pay attention to agitation.

1. Measure out the quantities of gasoline and oil to be mixed.

2. Put some of the gasoline into a clean, approved fuel container.

3. Pour in all of the oil and agitate well.

4. Pour in the rest of gasoline and agitate again for at least one minute. As some oils may be difficult to agitate depending on oil ingredients, sufficient agitation is necessary for the engine to last long.

Note that, if the agitation is insufficient, there is an increased danger of early piston seizing due to an abnormally lean mixture.

5. Indicate the contents on outside of container for easy identification to avoid mixing with raw gasoline or other containers.

■

FUELING THE UNIT

1. Untwist and remove the fuel cap.

2. Put fuel into the fuel tank to 80% of the full capacity.

3. Fasten the fuel cap securely and wipe up any fuel spillage around the unit.

WARNING

1. Select bare ground for fueling.

2. Move at least 10 feet (3 meters) away from the fueling point before starting the engine.

3. Stop the engine and let it cool for a few minutes before refueling the unit. At that time, be sure to sufficiently agitate the mixed gasoline in the container.

4. Do not smoke or place hot objects near fuel.

FOR YOUR ENGINE LIFE, AVOID;

1. FUEL WITH NO OIL (RAW GASOLINE) - It will cause severe damage to the internal engine parts very quickly.

2. GASOHOL - It can cause deterioration of rubber and/or plastic parts and disruption of engine lubrication.

3. OIL FOR 4-CYCLE ENGINE USE - It can cause spark plug fouling, exhaust port blocking, or piston ring sticking.

4. Mixed fuels which have been left unused for a period of one month or more may clog the carburetor and result in the engine failing to operate properly.

5. When storing the product for a long period of time, clean the fuel tank after rendering it empty. Next, activate the engine and empty the carburetor of the composite fuel.

6. When scrapping the used mixed oil container, scrap it only at an authorized repository site.

NOTE

For details of quality assurance, read the description in the Warranty section carefully.

Moreover, normal wear and change in product with no functional influence are not covered by the warranty. Also, note that if the usage in the instruction manual is not observed for the mixed gasoline, etc. as described herein, it may not be covered by the warranty.
