Carburettor adjustment
The carburettor was pre-set at the factory for optimum performance. If further adjustments are necessary, take
your blower to an authorized service center.
Spark plug
1. Spark plug gap = 0,635 mm. (Fig. 9)
2. Torque to 12-15 Nm. Connect the spark plug boot.
Cleaning the collection bag
A dirty bag will obstruct airflow, thereby reducing vacuum efficiency.
1. Detach the collection bag from the unit.
2. Open the zipper and remove the contents.
3. Turn the bag INSIDE OUT and shake vigorously. This procedure should be performed on a regular basis.
4. Turn the bag RIGHT SIDE OUT, close the zipper and attach to the unit.
NOTE:
If the collection bag is unusually dirty, it should be washed by hand in warm water with a mild deter-
gent. Rinse thoroughly. Let dry before use.
Storing the unit
WARNING:
Failure to follow these steps may cause deposit to form in the carburettor and difficult
starting or permanent damage following storage.
1. Perform all the general maintenance recommended in the “Maintenance” section.
2. Clean outside surface of the unit.
3. Drain fuel from the fuel tank.
4. After fuel is drained, start the engine.
5. Run the engine at idle until the unit stops. This will purge the carburettor of fuel.
6. Allow the engine to cool (approx. 5 minutes).
7. Using a spark plug wrench, remove the spark plug.
8. Pour 1 teaspoon of clean two-cycle oil into the combustion chamber. Pull the starter rope slowly several
times to coat internal components. Replace the spark plug.
9. Store the unit in a cool, dry place away from any source of ignition such as an oil burner, water heater etc.
Removing the unit from storage
1. Remove the spark plug.
2. Pull the starter rope briskly to clear excess oil from the combustion chamber.
3. Clean and gap the spark plug or install a new spark plug with proper gap.
4. Prepare the unit for operation.
5. Fill the fuel tank with proper fuel/oil mixture (see chapter ”Fuel and lubrication”).
