leave the control valve open when you have shut off the stove by turning the bottle to the
off position. if you close the valve when the stove is hot, it may be hard to open the next
time you use the stove.
6.
Close the fuel feed valve fully.
7.
Disconnect the fuel connector from the pump. sometimes, there may be some pressure
left in the bottle, which could release fuel when you disconnect the fuel hose. turn your
face away from the stove to protect your eyes and be sure not to disconnect the fuel hose
near open flames.
warning
risk of burning or serious injuries due to incorrect fuel pressure release.
• if you turn off the stove by closing the control valve only, you can only release the pressure
in the bottle by unscrewing the pump head from the bottle. this is potentially dangerous
as fuel could spill on you and your equipment.
• Do not remove pump from fuel bottle near a hot stove or open flame. fuel may splash on
the hot burner and ignite causing serious injury, possible death and property damage.
• Be very careful when lighting a stove that has just been used. a hot burner can vaporize
the fuel. Vaporized fuel is very difficult to see. there is a risk that the fuel will ignite
explosively causing burns.
• never move a burning or hot stove.

• When liquid fuels are used, the optimus Polaris can only be operated with
petroleum-based fuels (not with alcohol-based fuels).
• for optimal performance and less risk, we recommend to use chemically pure white gas or
high-quality kerosene.
• Under no circumstances should you handle fuel near an open flame, lit stove or in your
tent.
• Use a filter funnel when filling the bottle to avoid dirt and foreign contaminants getting into
the fuel bottle.
• never mix different kinds of fuel. Empty the bottle entirely before putting in a different fuel.
gaSOLine
• Gasoline is highly flammable, volatile, burns explosively and preheating occurs quickly.
only use with utmost caution.
• ordinary automotive gasoline contains additives which will contaminate your stove and are
hazardous to your health. if you have to use automotive gasoline, use unleaded wherever
possible.
