Frequently Asked Questions - MS 291 C-Q STIHL
What type of fuel does the STIHL MS 291 C-Q require?
It requires a 50:1 mixture of unleaded gasoline (minimum 90 octane) and STIHL two-stroke oil. Shake the mixture well before filling.
How do I adjust the chain tension?
Loosen the bar nuts, turn the adjusting screw clockwise to tighten the chain until it fits snugly against the bar with a slight gap on the underside. Then lift the bar tip and retighten the nuts.
What safety features does the MS 291 C-Q have?
This model is equipped with an inertia-activated chain brake, a throttle lockout, and a front hand guard to protect against kickback and accidental throttle operation.
How often should I clean the air filter?
Clean the air filter after every refueling or at least once per day of operation. A clean air filter ensures optimal engine performance and fuel efficiency.
Can I use a longer guide bar?
The MS 291 C-Q supports guide bars from 16 to 20 inches. Using a longer bar may affect balance and require adjusting the chain brake. Always use compatible bars and chains.
What is the ErgoStart system?
ErgoStart is an easy-start system that reduces the resistance of the starter rope by up to 50%, making it easier to pull the engine over quickly for reliable starting.
How do I maintain the chain sharpness?
Use a round file matching the chain pitch to sharpen each cutter at the correct angle. Always file from the inside of the cutter and maintain consistent tooth length for smooth cutting.
What should I do if the chain brake doesn't engage?
Stop using the saw immediately. Inspect the chain brake band for wear or debris. If the problem persists, contact your STIHL dealer for repair. Never operate the saw with a faulty chain brake.
Are spare parts easily available?
Yes, STIHL has an extensive dealer network and a full range of original spare parts for the MS 291 C-Q, ensuring perfect fit and safety compliance.
How do I store the chainsaw for long periods?
Drain the fuel tank and run the engine until it stops to avoid carburetor damage. Clean the saw thoroughly, coat the chain with light oil, and store in a dry, secure place.
