Frequently Asked Questions

2) Frequently asked questions

What kind of oil can i mix with the brushcutter?

Get a 2-cycle engine oil. If you decide to go with ZENOAH’s genuine oil (FC grade), the mixing ratio is 50:1, and if you opt for an oil that is easy to find in the market (FB grade), the ratio escalates to 25:1.

Can you elaborate how i can start the engine?

Begin by pouring fuel into the engine, followed by fastening the fuel cap, then sch a fuel cock is opened, close the choke lever, and finally, move the throttle lever to the starting position. After doing all this, pull the starter rope and after the engine has started, slowly drive the choke to enable a smoother start.

Is there something that I should avoid while I’m refueling?

Always ensure to stop the engine and let it cool before you begin refueling, this would limit the chance of an explosion from occurring. Keep in mind not to smoke or light a flame in the vicinity of the fuel, after all flies are common sense. To ensure there are no further hazards after the refueling process is done make sure to wipe any spills.

Would you recommend me on how I can maintain the spark plug?

To ensure that the spark plug is maintained in a proper condition you should begin by removing it and cleaning the electrodes as it is essential. Once it has been done, a proper adjustment of the spark gap should be done to the range of 0.6-0.7 mm, and later replacing the plug with a product of ZENOAH’s endorsement.

What steps should be taken once the blade has come into contact with a solid object?

First and foremost ensure that the engine has been turned off to eliminate any chances of it and the assembly overheating – then check if the blade has been damaged, and if it has, simply replace it with a new one.
