Frequently Asked Questions - MS 260 STIHL
How do I start the STIHL MS 260 chainsaw?
First, engage the chain brake. Then press the fuel primer bulb 3-5 times until fuel enters the bulb. Move the choke lever to cold start position. Pull the starter rope briskly until engine fires (usually 1-3 pulls). Then push choke back to run position and pull again to start.
What fuel mixture does the MS 260 require?
Use a 50:1 ratio of unleaded gasoline (90+ octane) to STIHL 2-stroke engine oil. Do not use pre-mixed fuels from gas stations as they may damage the engine.
How do I adjust the chain tension?
Loosen the bar nuts slightly. Turn the tensioning screw (located on the side of the saw) clockwise to tighten, counterclockwise to loosen. The chain should just touch the bottom of the bar and be snug. Then retighten the bar nuts.
What type of bar and chain oil should I use?
Use STIHL Oilomatic bar and chain oil or a high-quality adhesive bar oil. Never use used oil or hydraulic fluid.
How often should I clean the air filter?
Check and clean the air filter after every 10 hours of operation or more frequently in dusty conditions. Remove the filter cover and tap the filter gently; if heavily soiled, wash in warm soapy water and dry before reinstalling.
Why does my chainsaw chain not get oil?
Check the oil tank level. Ensure the oil outlet on the bar is not clogged. Also verify that the oil pump is adjusted correctly (use a screwdriver to turn the adjuster near the bottom of the saw). If still not working, the oil pump may need servicing.
How do I sharpen the chain on the MS 260?
Use a 5/32" (4.0 mm) round file at a 30° angle from horizontal. File each cutter from top to bottom. Check the depth gauges and file them down if they are above 0.025" (0.65 mm). Re-sharpen after every few hours of cutting.
What is the correct spark plug gap?
The recommended spark plug is a NGK BPMR7A or equivalent, with a gap of 0.5 mm (0.020"). Adjust if necessary using a feeler gauge.
Can I use ethanol-blended fuel?
STIHL recommends using gasoline with up to 10% ethanol (E10). Higher ethanol content (E15, E85) can damage the engine and void the warranty.
How do I store the chainsaw long-term?
Drain the fuel tank and run the engine until it stops to clear the carburetor. Remove the spark plug and pour a teaspoon of 2-stroke oil into the cylinder, then pull the rope slowly to distribute oil. Store in a dry, clean area away from direct moisture.
