INTERNAL COMBUSTION ENGINE
To ensure the greatest service life of the engine, monitor the oil level and check oil
and air filters for soiling on a regular basis. The cooling fins must be kept clean at all
times to ensure sufficient cooling of the engine.
INSPECTING THE SPARK PLUG
It is recommended to use F7TC spark plugs. To inspect the spark plug, proceed
as follows:
1. Remove the cap from the spark plug.
2. Use the spark plug wrench to remove the spark plug.
3. Thoroughly inspect the spark plug for visible damage. Replace it if necessary.
4. Measure the gap: it should be between 0.7 – 0.8 mm.
5. Before reusing the spark plug, thoroughly clean it with a metal brush to
remove soil. Be sure to check the gap.
6. Use the spark plug wrench to screw in the spark plug and replace the spark
plug cap.
MAINTAINING THE SPARK PLUGS
The spark plug is one of the most important items to ensure proper and sustainable
engine operation. Be sure to check the spark plug on a regular basis: it must be
intact, properly gapped and free of deposits.
