FAQ – STIHL KombiSystem
What is the recommended procedure for preparing my STIHL KM Series KombiMotor for long term storage (over 30 days)?
Only if you plan to "mothball" your lawn trimmer, brushcutter or chain saw for a longer period - say during the winter months - should you pay a little more attention to the topic of "care". This will ensure that your equipment, when required, will be ready for action straightaway. To get the equipment ready for winter, clean it first. The air filter, the cylinder fins, the spark plug and the dismantled cutting tool should be checked and cleaned (also see Instruction Manual). Metal parts should be lightly coated with with oil to protect them from rust and corrosion. The spark arresting screen in the muffler should be cleaned or replaced with a new one. The fuel tank should be emptied. Run the engine until the fuel system is dry (Warning! Do not operate the throttle, run the equipment only at idle speed until the engine stops!) STIHL recommends the use of STIHL MotoMix® fuel which is pre-mixed with STIHL HP Ultra synthetic oil. STIHL MotoMix® contains no ethanol and has a storage life of up to 2-years. STIHL MotoMix® can be left in the machine during seasonal storage. For winter storage, a dry and, if possible, dust-free and frost-free place would be ideal. You can save space if you hang the equipment. And remember: standard pump gasoline deteriorates; to avoid problems, only purchase enough fuel that can be used within sixty days unless it is STIHL MotoMix®.
My STIHL Kombi will start and idle but won't run or stalls when I go to full throttle. What's wrong?
There are several things you can check: first, make sure that you are using fresh fuel mix (never store or use fuel mix older than 60 days in can or fuel tank), second, clean spark arrester screen in the muffler, third, replace fuel filter in fuel tank, fourth, clean or replace air filter. If none of these work please take the machine to your local authorized STIHL servicing dealer for evaluation.
Why does my STIHL Kombi flood?
The most common reason is due to too many attempts trying to start the machine in the choke position. When starting a unit, make sure to follow the starting instructions in your instruction manual. The manual provides the proper instruction for starting procedures, but there are many conditions that may affect how the unit starts. A good rule of thumb to follow is to remember that when placing the switch control to the full choke setting, more liquid fuel and less air flow into the combustion chamber in order to create a higher chance for ignition. Pulling the rope more than two to three times in this setting may flood the engine. The operator should move the Master Control Lever™ or choke lever from the full choke setting after three to four pulls even if the engine does not fire. Moving the lever to the next setting, the half choke or part throttle position, will allow more air into the combustion chamber and help resolve the flooding condition.

Where do I find my serial number?
On Kombi units it is only located on the bar code label on the fan casing. On the professional models, it is on the bar code label and stamped in the top of the cylinder or main crank case. All current serial numbers will be 9 digits long and begin with the number 2.
Can I adjust my own carburetor?<
The carburetor comes from the factory with a standard setting. This setting provides an optimum fuel-air mixture under most operating conditions. With most carburetors, it is only possible to adjust the engine idle speed within fine limits. Quite often adjusting the carburetor will not solve acceleration issues. To find the correct setting for your machine please refer to your instruction manual. If you do not have a copy of your instruction please go to our product manual webpage where you can download a PDF version.
My STIHL Kombi unit was stolen. Do you track them?
STIHL Inc. maintains a stolen unit database. If your STIHL product was stolen, please report it stolen to your local law enforcement agency. Then contact us with your name, address, model number and serial number.
How often should I have my STIHL Kombi unit tuned up?
Please refer to your product instruction manual under the maintenance and repairs heading.
How can I tell when my STIHL Kombi unit was made?
STIHL does not incorporate production dates into our serial numbers. The serial numbering system is run consecutively from one production run and series to another.
What is the minimum compression for my STIHL Kombi unit?
Generally the minimum is 110 lbs of compression. However, this will vary by model and compression readings alone are not enough to determine the condition of the engine. Compression gauges are not always accurate and different engines will provide different results.
What is the correct spark plug gap for my STIHL trimmer, chain saw, or blower?
The correct gap setting is 0.020".
Will any other manufacturer's attachments fit my STIHL Kombi unit?
Only STIHL attachments will fit STIHL Kombi units.
Does STIHL offer an electric start chain saw, blower, or trimmer?
STIHL does not offer an electric start unit. We do however offer our Easy2Start™ system on some models.
How do I know if my STIHL Kombi unit is recalled?
Please go to our product recall webpage to see if your unit is listed. If it is part of the recall please take it to any authorized STIHL dealer.
