Cleaning the unit

Use a small brush for cleaning the outside of the unit. Do not use abrasive detergents. Household cleaners which contain aromatic oils such as pine oil or lemon as well as solvents such as kerosene may damage the plastic housing and handle. Wipe damp areas with a soft cloth.

Storage

• Never store the unit with fuel in the tank or in a location where petrol vapours may be ignited by a spark or naked flame.
  Before storing the unit, leave the engine to cool down.
• Store the unit in a dry, closed room to prevent unauthorised use or damage. Keep the unit away from children.

Long-term storage

i Note

Engines, which are stored for longer than 30 days, should not have any fuel in the tank to prevent the formation of residue in the fuel system, in particular on important parts of the carburettor.

If the unit is to be stored for a prolonged period, proceed as follows:

• Drain all the fuel out of the tank into a fuel container. Do not use fuel which has been stored for longer than 60 days.
• Start the engine and leave running until it stops. This ensures that all the fuel has been drained out of the carburettor.
• Leave the engine to cool down. Remove the spark plug and fill the cylinder with 15 ml of high-quality engine oil for 4-stroke engines. Slowly pull the starter rope to distribute the oil. Reinsert the spark plug.

i Note

After storing and before reusing the unit, remove the spark plug and drain all the oil out of the cylinder.

• Change oil. Dispose of waste oil in accordance with local regulations.
  Thoroughly clean the unit and check for damaged and loose components. Repair or replace damaged components and, if required, retighten the screws, nuts and bolts. The unit is now ready storage.

• Store the unit in a dry and secure location or at an adequate height to prevent any inadvertent use or damage. Keep out of the reach of children.
