Spark Plug
To ensure normal operation of the engine, proper spark plug gap must be maintained. Remove carbon buildup with
a wire brush. Proper gap of Spark Plug is 0.5-0.7 mm. See Figure 14
Muffler
After the muffler has cooled, remove dirt on or around muffler.
Engine Cooling Fins
Regularly remove debris and dust on the cooling fins of the engine cylinder to ensure that the cylinder can dissipate
heat. As the engine is air cooled, dirt and debris can effect the ability to cool and thus lead to failure if not properly
maintained.
Engine oil
The Oil must be changed after 10 hours of initial use, and then every 6 months or 50 hours of operation.
To change the oil:
1. For proper drainage, ensure that the engine and engine oil are warm.
2. Ensure that the fuel cap is fully tightened.
3. Remove the oil dipstick from the oil fill hole and drain the oil into a sealable container so that it can be
properly disposed of at a recycling center or service station.
4. With the engine in the upright position, add SAE 10W-30 engine oil to the engine fill hole until it reaches
the bottom edge of fill hole.
5. Reinstall the oil dipstick and wipe up any spilled oil.
