Stihl MS 194 T Instruction Manual

To start the Stihl MS 194 T, engage the chain brake, switch the master control lever to the start position, pull the starter rope until the engine fires, and then move the lever to the run position.
The correct fuel mixture for the Stihl MS 194 T is a 50:1 ratio of gasoline to Stihl two-stroke engine oil.
It is recommended to clean the air filter after every 10 hours of operation or more frequently if working in dusty conditions.
If the chain is not cutting properly, check for dullness, correct tension, and ensure the chain is properly lubricated. Sharpen or replace the chain if necessary.
To adjust the chain tension, loosen the bar nuts, use the tensioning screw to adjust the chain, and then retighten the bar nuts while ensuring the chain has the correct tension.
After each use, clean the saw, inspect the chain and guide bar for wear, check the air filter, and ensure the chain brake is functioning properly.
If the chainsaw stalls when idling, it may be due to incorrect carburetor settings, a clogged air filter, or fuel issues. Adjust the carburetor and clean the air filter to resolve the issue.
To replace the spark plug, remove the spark plug boot, use a spark plug wrench to unscrew the old plug, install the new plug, and reattach the boot. Ensure the plug is properly gapped.
Signs of a worn-out chain include difficulty in cutting, excessive vibration, and the chain not holding tension. Replace the chain if these symptoms are present.
To prevent overheating, ensure proper air circulation by keeping the cooling fins clean, use the correct fuel mixture, and avoid prolonged idling.
