FAQ Fehlerbehebung

Die "ON/OFF"-Funktion der Pumpe durch Drehen der Flasche funktioniert nicht. Der Brennstoffschlauch ist verbogen.

Bei längerer Lagerung kann es sein, dass sich der Schlauch für die Brennstoffzufuhr verbiegt.
Damit die „ON/OFF"-Funktion der Pumpe durch Drehen der Brennstoffflasche optimal funktioniert, muss der Brennstoffschlauch vom Pumpenschaft weg zeigen, und zwar in die gleiche Richtung wie die „OFF"-Position der Pumpe. Der Schlauch lässt sich leicht mit den Fingern zurechtbiegen und sollte so aussehen wie auf dem Bild:

Der Schnellanschluss ist am Bajonettverschluss der Pumpe nicht ganz dicht. 

Mit einem Wattestäbchen etwas Silikonfett am Innern des Bajonettverschlusses der Pumpe anbringen.
Dabei bis zur Gummidichtung vordringen. So lässt sich der Schnellanschluss leichter anbringen und dichtet optimal ab.

Es lässt sich mit der Pumpe zuwenig Druck aufbauen in der Brennstoffflasche. Das Pumpen ist schwer.  

Für einen optimalen Druckaufbau sollte das Pumpenleder regelmässig überprüft werden. Dazu den Pumpendeckel aufschrauben und den Pumpenstössel herausziehen. Das Pumpenleder am Ende des Stössels sollte weich und feucht sein. Ist dies nicht der Fall, etwas vom mitgelieferten Silikonfett in den Pumpenschaft drücken. Den Pumpenstössel wieder einsetzen und einige Male pumpen, damit sich das Fett gleichmässig um das Leder und im Pumpschaft verteilt. Bei Bedarf wiederholen.

How do I fit my Optimus Nova into my Trangia cook set? 

With the Trangia adapter No. 9100 it is possible to fit the Optimus Nova burner inside Trangia cook sets No. 25 and No. 27. To fit the adapter to the Optimus Nova burner and to fit the burner inside the windshield, follow the instructions below.

A. Fitting the Adapter No. 9100 on your Optimus Nova burner.

  1. Unscrew and remove the fuel hose from the burner. Unscrew the nut at the bottom of the burner.
  2. Remove the burner cup with legs. It is possible, but a little tricky, to bring the control key assembly out of the hole on the burner cup.
  3. Fit the adapter on the burner, threading through the hole on the adapter. The arms of the adapter should point upwards, so that the arms are level with the burner head. Fit the priming wick below the adapter.
  4. Fit the enclosed priming cup. Do not forget to tighten the nut. Fit and tighten the fuel hose again. Ensure there are no fuel leaks before lighting the burner.

B. Fitting OPTIMUS NOVA into the Trangia windshield.

  1. Fit your Optimus Nova burner into the hole for the meths burner from above. Start with the fuel hose; put it through the small hole designated for multi-fuel burner adaptations. Fit the control valve through the larger hole. If you have an older model of Trangia you may be forced to make own holes for the fuel hose and the control valve.
  2. Press the Optimus Nova burner downwards a bit until the adapter locks onto the windshield.
  3. Connect the Optimus Nova to the pump and fuel bottle and you are ready to go. (Refer to your Optimus Nova user manual).

How to do at high altitude? 

At high altitude the airs oxygen level is reduced. If the stove burns rich, open up any wind screens to let more oxygen to the stove. Liquid fuels seem to be more volatile at high altitude. Always be careful when filling your stove.At high altitude the airs oxygen level is reduced. If the stove burns rich, open up any wind screens to let more oxygen to the stove. Liquid fuels seem to be more volatile at high altitude especially paraffin (kerosene) fuel. Always be careful when filling your stove.

 Why is pump operation squeaky and sluggish? 

Pump rubber O-ring / leather cup has dried. Remove the pump rod. Lubricate the O-ring / leather cup in mineral oil.

Why is the burner flame yellow, high and sooting instead of bluish and controlled? 

  1. The stove has not been sufficiently primed. Consequently, the fuel is not vaporized properly, and combustion is inefficient. Turn off the stove and repeat the priming. Be extremely careful when filling the priming cup if the stove is already hot. Remember that liquid fuels (especially gasoline/petrol) are volatile and may ignite explosively. Best advise is therefore to let the stove cool off prior to filling the priming cup with fuel or paste again.
  2. Wrong fuel or bad quality fuel is used. A stove designed for gasoline only will not work off kerosene/paraffin. The burner of a gasoline stove is not designed to vaporize fuel kinds that are less volatile than gasoline. Kerosene/paraffin, diesel and similar fuels will consequently not vaporize in a gasoline stove, instead high, flaring, yellowish flames that are both dangerous and uncontrollable are produced. Most kerosene/paraffin stoves will work off diesel oil. The quality of diesel oil varies however a lot both geographically and with manufacturer. In some cases, the diesel will have a boiling and vaporization point that is too high resulting in insufficient vaporization when used in a stove. Typically this would be the case with diesel oil for marine use, which in many countries is thicker and more oily than diesel intended for cars.
  3. You are using a burner jet that is not correct (to large orifice) for the fuel type used. Apply the correct burner jet. High yellow flames would for instance be a typical symptom if the alcohol jet is fitted when running the stove off other fuels.
  4. Slide valve or restrictor tubes are fitted incorrectly or fitted but not necessary. Turn off the stove and remove restrictor tubes alternatively adjust or remove the slide valve. Under normal conditions using kerosene/paraffin, white gasoline or diesel, there is no need to apply restrictor tubes or the slide valve. Remove them from the burner and keep them in a safe place. The only time a restrictor tube or a slide valve MUST be used is when running a stove off methylated spirits/alcohol. (only Optimus Hiker)
  5. Burner jet is worn out. Replace the burner jet.

Why won't my stove build up pressure in the tank? 

  1. Tank lid or airscrew not fitted tightly. Tighten the tank lid, airscrew and / or the pump.
  2. Tank lid rubber packing or pump packing has stiffened, cracked or similar. Replace the packing.
  3. Pump rubber O-ring / leather cup has dried. Remove the pump rod. Lubricate the O-ring / leather cup in mineral oil.
  4. Pump rubber O-ring / leather cup has stiffened, cracked or similar. Replace and lubricate the O-ring / leather cup.
  5. Pump valve defective or blocked by debris. Clean or replace the pump valve.
