MAINTENANCE Clean the outside of the spark plug. Remove it and check the electrode gap. Adjust the gap to 0,6-0,7 mm, or replace the spark plug. Check that the spark plug is fitted with a suppressor. 0,6-0,7 with a new one at regular intervals. A damaged air filter must always be replaced. If the machine is used in dusty conditions the air filter should be soaked in oil. See instructions under the heading Oiling the air filter. Oiling the air filter CAUTION! Always use the recommended spark plug type! Use of the wrong spark plug can damage the piston/ cylinder. Always use the recommended spark plug type (NGK BPMR7A)! Use of the wrong spark plug can damage the piston/cylinder. Air filter Always use special filter oil. Filter oil contains a solvent to make it spread evenly through the filter. You should therefore avoid skin contact. Put the filter in a plastic bag and pour the filter oil over it. Knead the plastic bag to distribute the oil. Squeeze the excess oil out of the filter inside the plastic bag and pour off the excess before fitting the filter to the machine. Never use common engine oil. This would drain through the filter quite quickly and collect in the bottom. The air filter must be regularly cleaned to remove dust and dirt in order to avoid: • Carburettor malfunctions. • Starting problems. • Loss of engine power. • Unnecessary wear to engine parts • Excessive fuel consumption. Check the airfilter and clean it when it´s necessary. Avoid contact with hot surfaces on muffler, cylinder etc. Contact can result in burns to the skin. Cleaning the air filter • Remove the air filter cover and take out the filter.Wash it clean in warm, soapy water. • Refit the air filter and air filter cover. Do not forget to put the air screen back in place. If the grill is missing, the air cleaner is not properly sealed, and dust can get into the cylinder. Shoulder strap If the shoulder strap is damaged, it may break while in use and the machine may fall causing personal injury. Follow the instructions below to replace the shoulder strap. 1 Remove the clamp from the strap. 2 Run the end of the strap through the hanger. 3 Refit the clamp to the strap. WARNING! Check that the thick round ! pin in the clamp is inserted in the strap. If it is inserted incorrectly it may lead to personal injury. An air filter that has been in use for a long time cannot be cleaned completely. The filter must therefore be replaced 18 - English
