Check the air filter every time the engine is running. You will need to clean the air filter more often
if you are working in very dusty places.
Note: Operating the machine without an air filter or with a damaged air filter will allow dirt
to enter the engine, resulting in rapid engine wear. This type of damage is not covered by the
warranty.
15.1. AIR FILTER DESCRIPTION AND CLEANING
ATTENTION! The air filter must be serviced (cleaned) after 25 hours of normal operation. Do
this more often when working in extremely dusty places.
15.1.1. Release the air filter cover.
15.1.2. Remove the air filter cover. Be careful to prevent dirt and debris from getting into the
base of the air filter.
15.1.3. Remove the pre-filter and air filter from the base of the air filter.
15.1.4. Check the air filter elements. Clean contaminated items.
15.1.5. To clean the debris, carefully tap the filter over a hard surface. Never attempt to clean
the dirt by brushing, as this may cause the dirt to be pushed inside the filter. If the filter is too dirty,
replace it with a new filter.
15.1.6. Reinstall the filter and pre-filter.
15.1.7. Close the cover and secure it.
Note: Replace the filter if it is distorted, torn, damaged or cannot be cleaned.
16. CANDLES
For best results, replace the candle every 100 hours of operation. Use only the recommended
spark plug, which is the correct heat range for normal engine operating temperatures. To find the
latest types of recommended candles, please contact an authorized service center.
ATTENTION! If the engine was running, the exhaust and spark plug would be very hot. Be
careful not to touch these parts.
Note: Incorrect spark plugs can cause engine damage. For good work, the candle must be
properly opened and free of injuries.
16.1. Disconnect the spark plug cap and remove any contamination from the spark plug area.
16.2. Use the correct spark plug wrench to remove the spark plug.
16.3. Check the spark plug. Replace it if damaged, badly dirty, if the washer is in poor condition
or if the electrode is worn.
16.4. Measure the electrode distance with a suitable tool. The correct distance is described in
the SPECIFICATIONS in the manual. If you need to change the distance, bend the electrode slightly.
16.5. Carefully install the candle by hand to avoid cross threading.
16.6. Once the candle is inserted, tighten the correct size wrench to tighten the washer.
16.7. When inserting a new spark plug, tighten 1/2 turn after the spark plug seats to compress
the washer.
16.8. When reinstalling the original spark plug, tighten 1/8 - 1/4 turn after the spark plug seats
to compress the washer.
16.9. Attach the candle cap to the candle.
Note: A loose candle can get very hot and damage the engine. Excessive tightening of the
candle can damage the threads in the cylinder head.
17. EXHAUST
17.1. Allow the exhaust, engine cylinder and fins to cool before touching.
17.2.Remove accumulated residues from the exhaust area and the cylinder area.
17.3. Make sure the exhaust is free of cracks, corrosion or other damage.
