1． Water supply ※be sure to fill the water fully!

First, remove the overflow plug and the relief valve from the boiler. Next place the boiler flatly and pour water
from the relief valve inlet. To avoid burnout, be sure to pour the water until it flows from the overflow outlet.
When you finish filling, fix the overflow plug and the relief valve tight with your fingers. (DO NOT USE any tools
such as pliers.)
Also from the 2
When you pour water after the operation, wait until the boiler cools as you can touch by hand.

nd

operation, be sure to confirm overflow.

2． Oil filling to each part of the boiler & burner

For each operation, fill the machine oil to the rotor inside the regulator of the boiler using oil filler or so. Besides,
fill the oil to the pillow block next to the flywheel and link parts of the steam engine (engine is sold separately).
In addition, fill the attached steam oil fully to the oiler which has “OIL” mark on its cap.

3． Fuel supply ※Never fill fuel over 40cc.

・For the 1st operation (when there’s no fuel remains in the burner)：

Remove the relief valve of the burner and pour the fuel (methanol or fuel grade alcohol) filled in the measure cup
(approx. 40cc) from the inlet into the burner. When you finish filling, fix the relief valve tight with your fingers.
(DO NOT USE any tools such as pliers.)

・After the 2

Pull out the burner from the boat body and remove the relief valve. Turn the burner upside down to allow the fuel
inside to flow out. Make sure no fuel remains inside the burner. After that, pour the fuel by same procedure as 1
operation.

Precaution for the water and fuel supply

In the following cases, it’s possible to burnout (overheat with low-water) because burning time would be longer
in comparison to the water level in the boiler. If it gets burnout, brazing parts melt and result in water leakage
and breakdown of the boiler.

・ Didn’t fill water fully to the boiler.
・ Pour the fuel more than 40cc.
・ Pour the fuel despite that there was fuel remains in the burner.

※The burner is exclusive to using alcohol therefore DO NOT USE the other fuel such as gasoline or kerosene

and so on.
