Coldest this morning!

We got the coldest morning in Osaka Japan 7 celsius below 10, the alcohol fuel for model airplane would have some difficulty because of fuel atomization, I would often utilize Diethyl Ether for priming choke in such case.
Also connecting plastic hoses in the equipments break this morning because of physical phenomena, material temperature shrinking.

Air supply hose must be repaired first, otherwise we would hear the noisy operation sound of air compressor today.
Even on the general machinery, necessary periodical replacement parts must be replaced at any rate, however much payment should be required, no way to hide, any dodges aren't effective in the Scientific World.

Unexpected expenses occur when something moves, it cannot be avoided in the world?
