FUEL IS LEAKING OUT
• Between the bottle and the pump
Check that the pump is screwed on securely.
Check the rubber gasket, and replace it if it is damaged.
• At the quick connect
Check the O-ring on the tip of the fuel hose and replace it if it is damaged, worn or missing.
• At the connection between the fuel hose and the stove
Unscrew the control and check the O-rings. Replace it if damaged.
• From the hole where the pump rod enters the pump
The pump’s drain valve is leaking and has to be replaced. This is also evident by the pump rod
slowly coming out of the pump pipe.
THE FLAME IS YELLOW AND FLARING
• Insufcient preheating
Repeat the entire preheating process, or close the control and wait a while before switching it
back on.
• You have turned the control valve too far
Turn the control valve back.
• Impure fuel
Use only petroleum based fuels such as gasoline, kerosene and diesel. Do not mix different
types of fuel.
• Poor oxygen supply
Make sure that your stove has free access to air.
• The nozzle is loose
Leave the stove to cool, then screw the nozzle into position.
THE STOVE IS NOT VERY HOT
• Bottle pressure too low
Pump a few times in order to increase the pressure in the bottle. If this does not help, check
whether the pump leather is dry or damaged. Soften it with your fingers, and lubricate it with
Optimus lubricant or replace it if so required. Check also that the pump is screwed together
properly.
• Nozzle blocked
Clear the nozzle by moving the multitool magnets beneath the burner. If this does not help, you
will have to remove the nozzle and push the cleaning needle through the nozzle hole from the
inside.
• Fuel lter clogged
If output increases when the fuel bottle is turned to the off position, then the fuel filter is clogged.
Replace the fuel filter. See Advanced maintenance for details.
• Fuel grooves on the spindle blocked
Unscrew the spindle and clean the grooves.
