Maintenance
Warning: Some maintenance procedures may require special tools or skills. If you are unsure about these procedures, take your unit to an authorised service
dealer.
Warning: Never do maintenance or repairs with the unit running. Always do maintenance and repairs on a cool unit. Disconnect the spark plug wire to ensure
the unit will not start.
Maintenance schedule
The required maintenance procedures should be performed at the frequency stated in the table. They should also be included as part of any seasonal tune-up.
Frequency Maintenance required
Daily Remove dirt and debris from the blower exterior.
Inspect the engine, tank, and hoses for possible leaks, and repair as necessary.
• Inspect the engine cooling fins tor accumulation or dirt or debris, and clean as necessary.
• Inspect the entire machine tor damage, loosen or missing components or fastenings, and repair as necessary.
Every 5 hours Clean and re-oil the air filter.
Every 10/15 hours Check spark plug condition and gap.
Every 50 hours Inspect the entire machine and tubes for damage, including loose or missing components, and repair as necessary.
Check spark plug condition and gap.
Check fuel filter.
Periodically Clean the arrestor screen.
Checking the air filter (fig. 20 -21)
This should be done more frequently in dusty conditions.
1. Accumulated dust in the air filter will reduce engine efficiency, increase fuel consumption and allow abrasive particles to pass into the engine. Remove the
air filter as often as necessary to maintain in a clean condition.
2. Light surface dust can readily be removed by tapping the filter.
3. Heavy deposits should be washed out with a suitable solvent.
4. Remove the filter cover by pressing the part of the inside cover shown as Fig.20.

Checking the spark plug
1. Use the spark plug wrench to remove the spark plug (turn counter-clockwise to remove) (Fig.16).
2. Clean and adjust the spark plug gap to 0.6˜0.7mm. Replace any damaged or visibly warn spark plug.
3. Install the spark plug finger-tight in the cylinder head,and then tighten it firmly with the spark plug wrench.
Warning: Never allow dirt or debris to enter the cylinder bore. Before removing the spark plug thoroughly clean the spark plug and cylinder head area. Allow
the engine to cool before servicing the spark plug. Incorrect spark plug installation can result in serious engine damage.
Checking the fuel filter (Fig.23)
1. The fuel tank is fitted with a filter. The filter is situated at the free end of the fuel pipe and can be picked out. (Fig.23).
2. Check the fuel filter periodically. Do not allow dust to enter the fuel tank. A clogged filter will cause difficulty in starting the engine or abnormalities in engine
performance.
3. When the filter is dirty, replace the filter.
4. When the inside of the fuel tank is dirty, it can be cleaned by rinsing the tank out with petrol.
Cleaning
• Use a small soft brush to clean the outside of the unit. Do not use strong detergents. Household cleaners that contain aromatic oils such as pine and lemon,
and solvents such as kerosene,can damage plastic housing or handle. Wipe off any moisture with a soft cloth.
• Empty the vacuum bag. Turn it inside out and shake off any excess debris. Hand wash the empty vacuum bag annually with soapy water and allow to air dry.
Storage
• Never store the unit with fuel in the tank.
• Allow the engine to cool before storing.
• Lock up the unit to prevent unauthorized use or damage.
• Store the unit in a dry, well-ventilated area.
• Store unit out of reach of children.
Long term storage (winter)
Should the unit will be stored for an extended time,use the following storage procedure.
1. Drain all fuel from the fuel tank. Do not store mixed fuel for more than 60 days.
2. Start the engine and allow it to run until it stalls. This ensures that all the fuel has been drained from the carburettor.
3. Thoroughly clean the unit and inspect for any loose or damaged parts. Repair or replace damaged parts and tighten loose screws,nuts or bolts. The unit is
ready for storage.
NOTE: Remember to have your machine serviced at an authorized service centre at least once a year!
Transporting
• Allow the engine to cool before transporting.
• Secure the unit while transporting.
• Tighten the fuel cap before transporting.
