Frequently Asked Questions

Frequently Asked Questions

Q1: How do I start the engine properly?

To make everything clearer, please consult the instruction manual. The steps are simply are:

  • Fill the specified amount of oil and gasoline
  • Turn on the fuel cock
  • Turn on the engine by switching to ON.
  • Pull the choke and then the recoil starter
  • Once the engine is warmed, return the choke
  • Connect the outlet of the electrical device

Q2: What should I consider when installing a generator in a camping car?

It is crucial to consider all factors like vibration, heat, intake, wiring, exhaust, and even safety and maintenance. You’d better consult a specialized company that manufactures a camping car.But there are some key points you need to remember:

  • When you operate the engine, you must place it at least 50 centimeters (with the exhaust port at least 1 meter) from the wall as well as equipment.
  • Don’t enclose the periphery of the generator or use it when covered with a box.
  • Don’t use in locations where the exhaust gas is muffled.
  • If you plan to transport the generator in an automobile, secure it firmly to prevent it from tipping over.

Q3: Should I refill oil?

You should change the amount of oil regularly without refilling to extend the lifespan of the engine. To be specific, replacing the oil every 100 hours of use is ideal.

Q4: What if I let the amount of oil too low? Why does the engine stop working in case of low oil?

When the oil reaches a particular level or less, the oil-warning system will be turned on to prevent the engine from burning; and the engine will stop to protect itself.If the oil is deficient, a red lamp is lit upon pulling the recoil starter to let you know the missing oil.

Q5: What if an excessive amount of oil is added?

Too much oil will increase the resistance in the engine. The result is that smoke may be sent out from the muffler, or oil may leak from the air cleaner via the breather hose.And of course, when the oil accumulates in the muffler, the performance will decrease. So, it is so necessary to apply the exact amount of oil as specified in the instruction manual.

Another reason of an excessive amount of oil may be that you place the generator in a tilt position. Just rearrange it horizontally, fill the exact amount into the oil hole through an oil jug or by wrapping a piece of A4 paper around the hole. Everything will be fine.

To sum up,

Considering your need, you can choose the generator with a suitable output.

If you just have a normal need like powering vital household appliances or RV’s, you can go with the Yamaha EF2000iSv2. It provides adequate output, has high runtime compact design for super portability, and especially, reasonable price.

We hope you will succeed in finding the right inverter generator.
