Operation

Introduction

WARNING: Read and understand the safety chapter before you use the product.

Fuel
This product has a two-stroke engine.

• CAUTION: Incorrect type of fuel can result in engine damage. Use a mixture of gasoline and two-stroke oil. Premixed fuel
• Use Husqvarna premixed alkylate fuel for best performance and extension of the engine life. This fuel contains less harmful chemicals compared to regular fuel, which decreases harmful exhaust fumes. The quantity of remains after combustion is lower with this fuel,
• which keeps the components of the engine more clean.
• To mix fuel

Gasoline

• Use good quality unleaded gasoline with a maximum of 10% ethanol contents.
• CAUTION: Do not use gasoline with an octane grade less than 90 RON/87
• AKI. Use of a lower octane grade can cause engine knocking, which causes engine damages.

Two-stroke oil

• For best results and performance use Husqvarna two-stroke oil.
• If Husqvarna two-stroke oil is not available, use a two-stroke oil of good quality for air-cooled engines. Speak to your servicing dealer to select the correct oil.
• CAUTION: Do not use two-stroke oil for water-cooled outboard engines, also referred to as outboard oil. Do not use oil for four-stroke engines.

To mix gasoline and two-stroke oil

CAUTION: Small errors can influence the ratio of the mixture drastically when you mix small quantities of fuel. Measure the quantity of oil carefully and make sure that you get the correct mixture.
(Fig. 23)

1. Fill half the quantity of gasoline in a clean container for fuel.
2.  Add the full quantity of oil.
3.  Shake the fuel mixture.
4. Add the remaining quantity of gasoline to the container.
5.  Carefully shake the fuel mixture.

CAUTION: Do not mix fuel for more than 1 month at a time.

To fill the fuel tank
WARNING: Obey the procedure that follows for your safety.

1. Stop the engine and let the engine become cool.
2. Clean the area around the fuel tank cap. (Fig. 24)
3. Shake the container and make sure that the fuel is fully mixed.
4. Remove the fuel tank cap slowly to release the pressure.
5. Fill the fuel tank. CAUTION: Make sure that there is not too much fuel in the fuel tank. The fuel expands when it becomes hot.
6. Tighten the fuel tank cap carefully.
7. Clean fuel spillage on and around the product.
8. Move the product 3 m/10 ft or more away from the refueling area and fuel source before you start the engine.

Note: To see where the fuel tank is on your product, refer to Product overview on page 6.

7. Pull the starter rope handle quickly with the right hand until the engine starts or attempts to start, maximum 6 times. If the engine starts, move the choke lever gradually to the open position and continue to step 11. If the engine does not start, continue to step 9.

8. When the engine attempts to start, move the choke lever gradually to the open position.

9.  Pull the starter rope handle quickly with the right hand until the engine starts, maximum 6 times.
   Note: If the engine does not start, repeat the starting instructions from step

11. Let the engine run for 30 seconds.

12. Put the throttle control at idle speed. (Fig. 28)

13. Push the throttle trigger to adjust the blower speed. Refer to To use the throttle trigger on page 11.

To start a warm engine

• If the ambient temperature is below 32°C / 90°F, use the same starting procedure as To start a cold engine on page 11 but do not put the choke control in the closed choke position.
• If the ambient temperature is above 32°C / 90°F, use the same starting procedure as To start a cold engine on page 11.

To use the throttle trigger

• To increase the blower speed during operation, push the throttle trigger until you get the correct speed. (Fig. 29)
• To decrease the blower speed during operation, release the throttle trigger until you get the correct speed.

To start the engine when the fuel is too hot

To adjust the idle speed

1. Make sure that the air filter is clean and that the air filter cover is attached.
2. Adjust the idle speed with the idle speed screw. To see where the idle speed screw is on your product, refer to Product overview on page 6.

To do a check of the spark plug
CAUTION: Use the recommended spark plug. Refer to Technical data on page
An incorrect spark plug can cause damage to the product.

1. Stop the engine and let the product become cool.

2. Clean the spark plug if it is dirty.

3. Make sure that the electrode gap is correct. Refer to
   Technical data on page 16. (Fig. 38)

4. Replace the spark plug monthly or more frequently if it is necessary.

To do maintenance on the muffler
CAUTION: If the spark arrestor screen is frequently blocked, it can be a sign that performance of the catalytic converter is decreased. Speak to you servicing dealer to examine the muffler. A blocked spark arrestor screen causes overheating and results in damage to the cylinder and piston.

• CAUTION: The spark arrestor screen must be replaced if it is damaged. Do not use a product if the spark arrestor screen on the muffler is missing or defective.
• Clean the spark arrestor screen on the muffler. Use a wire brush. (Fig. 39)
• Let a servicing dealer replace or do service on the muffler and the spark arrestor screen after 50 hours of operation.

To examine and clean the cooling system
The cooling system includes the cooling fins on the cylinder and the air intake screen.

1. Stop the engine.

2. Make sure that the cooling system is not dirty or blocked. If it is necessary, clean the air intake screen and cooling fins.
   CAUTION: A dirty or blocked  ooling system can increase the temperature of the engine and cause damage to the product. A clogged air intake screen decreases the blow force.

3. Examine the cooling system for damages. Make sure that the parts are attached correctly to the product.

To clean the air filter

1. CAUTION: Do not use a product without an air filter or with a damaged air filter. Dust in the air can cause damage to the engine.

2. push the choke control to the closed position.

3. Remove the air filter cover (A). (Fig. 40)
   Remove the pre-filter (B) from the air filter cover.

4. Remove the air filter (C) from the filter frame.

5.  Clean the pre-filter and the air filter with warm water and soap.
   Note: An air filter that has been used for a long time cannot be fully cleaned. Replace the air filter regularly and always replace a defective air filter.

6.  Clean the inner surface of the air filter cover (A) with a brush.

7.  Put the air filter in the filter frame.

8. Attach the pre-filter to the air filter cover.

9.  Attach the air filter cover to the product.
