3) Spark Arrester (optional equipment)
The engine is not factory-equipped with a spark arrester.
In some areas, it is illegal to operate an engine without a spark arrester. Check local laws and
regulations. An optional USDA approved spark arrester is available.
The spark arrester must be serviced every 100 hours to keep it functioning as designed.
1.
Allow the engine to cool and disconnect
the spark plug cap.
2.
Remove the muffler heat shield,
identification plate, muffler, and gasket.
3.
Remove the spark arrester from the muffler.
4.
Check for carbon deposits on the spark
arrester and the exhaust port. Brush
carbon deposits away. Be careful to avoid
damaging the spark arrester screen.
5.
Installation is the reverse of removal.
Tighten all hardware securely.
6.
Install the spark plug cap on the spark plug.
4) Cleaning the air filter
Failure to clean the air filter regularly will cause not only output deficiency and higher fuel
consumption but will also lead to an increase in exhaust gas temperature and the possibility of
a fire.
Cleaning, replacement time (approx.)
Take care to clean the filter more frequently when operating in an environment with a lot of dust
or grime.
1.
Release the wing nut and filter cover.
2.
Remove the paper and foam elements and check
them for damage.
Note:
Replace with new parts if damaged.
3.
Wash the foam element with a pH neutral detergent.
After washing, be sure to squeeze out all the water and
allow it to dry. After that, soak it in new engine oil
(SAE10W-30 or equivalent), wring it out thoroughly,
and then shake to remove any surplus oil.
4.
Lightly tap the paper element several times to remove any waste. Blow any dirt from the inside
of the filter in an outward direction.
●
Replace the paper element with a new one if it is very dirty.
●
When lubricating, tap the paper element so as not to cause any damage to the filter.
●
Do not use a brush as this could scrape the filter.
●
When cleaning the filter, please keep foreign objects out of the air intake.
5.
Wipe any dirt from the inside of the case and reassemble back to its original position.
