Original User Manual FX-4MS131_rev03
Check the oil level.
1 Place the engine horizontally on the floor.
2 Unscrew the dipstick and check the oil level,
which should be up to the oil filler neck
3 If the oil level is too low, add the recommended oil
up to the oil filler neck.
4 Close the oil cap.
WARNING
The capacity of the oil tank is 75ml.
Due to the low capacity, it is necessary
to fill the oil slowly to avoid overflow and spillage.
Check the oil level every 10 working
hours and top up if necessary
WARNING
We recommend the Oregon 4-stroke oil
or other brand oils
SAE 10W-30 in average ambient temperature.
WARNING
The use of 2 stroke oil is not allowed and reduces the life of the engine. The
recommended operating temperature is between -5℃ and +40℃
Recommended fuel
It is recommended to use unleaded gasoline with an octane number of 90 # or higher to reduce
carbon deposition in the combustion chamber. Do not use old or dirty gasoline. Do not use a fuel
mixture of engine oil and gasoline. Keep the fuel tank dust-free and avoid water getting into the
tank. Sometimes misfiring will occur due to usual overload.
If the backfires are heard under the average load, we recommend changing the gasoline. If the
misfire is still present afterwards, please consult an authorized workshop.
WARNING
● Gasoline is highly flammable, and sparks can cause an explosion.
● Refuel only in well-ventilated rooms and let the engine cool down before filling. Smoking and
