CLEARING THE JET WITH THE SHAKER NEEDLE
1. Close Pump Control Valve and wait
5 minutes for stove to cool.
2. Shake stove up and down.
Shaker Needle inside Jet should rattle.
3. Preheat and run stove.
If performance does not improve, perform
Cleaning the Jet and Fuel Line steps.
CLEANING THE JET AND FUEL LINE
1. Fold Pot Supports/Legs to packed position.
2. Unscrew Priming Cup and remove Wick.

Deposits in the Jet and Fuel Line reduce fuel flow and impair stove performance. Minor
deposits in the Jet can be cleared with the Shaker Needle. Major deposits may require more
extensive cleaning of the Jet and Fuel Line. At a minimum, perform the following maintenance
annually, or every time you perform the Pump Maintenance.
PUMP MAINTENANCE STOVE MAINTENANCE
O-rings can become dry, cracked or torn
with use. Their lifespan is affected by dirt,
debris, temperature, friction and frequency
of use. For this reason, please inspect your
O-rings before every trip. Replace dry,
cracked, or torn O-rings immediately, and
replace all O-rings annually, regardless
of appearance. Replacement O-rings and
Pump Seals can be found in the Annual
Maintenance Kit, or the more comprehensive
Expedition Service Kit, purchased separately
from an MSR®dealer.
REPLACING FUEL TUBE O-RING
1. Remove Plunger.
Align, twist, and pull.
2. Remove Fuel Tube Bushing and O-ring
with Jet and Cable Tool.
Remove the O-ring with the end of the
Fuel Line or Safety Pin.
3. Inspect O-ring and replace if damaged.
If needed, a spare red Fuel Tube
O-ring is provided.
4. Lubricate Pump Cup.
Use a drop of Pump Cup Oil or any
mineral-based oil.
5. Insert Plunger.
Hold thumb and forefinger firmly
around Arrow 1.

WHISPERLITE™INTERNATIONALE
TROUBLESHOOTING
FUEL INFORMATION
The WhisperLite™Internationale stove burns a variety of fuels by using two interchangeable Jets.
1. The IG Jet is used for White Gas and Unleaded Auto Gas. This Jet is preinstalled in your stove.
2. The K Jet is for Kerosene and Diesel. This Jet is included in the parts kit with your stove.
To exchange Jets, see “Cleaning the Jet and Fuel Line.”
Use MSR®SuperFuel™(White Gas) for optimal performance. It is the highest quality fuel available for your stove.
Do not use leaded fuels. Fuels other than MSR SuperFuel white gas lead to rapid stove clogging and require
more frequent Jet and Fuel Line cleanings. Also, the use of Unleaded Auto Gas may shorten stove lifespan. Use
the fuels chart below to help you find your fuel when traveling internationally.
Visit www.msrgear.com for more information on international fuel names and safe stove transportation.
