smoke generator is not working properly. What should I do?
smoke unit should already be primed at the factory so you should see smoke coming
out of the exhaust after a while once the heating filament has got working. If
no smoke comes out after a while, add a few drops of smoke oil into each nozzle.
Wait for the heating element to work. You should be able to see the smoke pumping
away after a while. You can switch off the smoke generating unit if you wish.
