Verify that the chain is properly lubricated and that the oil reservoir is filled to the correct level, as oil delivery affects chain tension behavior during operation.
To check chain tension, place the bar and chain against a solid surface and pull the chain away from the drive link slightly. A correctly tensioned chain should show a small amount of slack, typically about 3–5 millimeters, with the drive links sitting fully within the groove of the bar. If the chain hangs below the bar or shows excessive slack, loosen the nuts that secure the bar, rotate the tensioning screw counterclockwise to tighten, and retighten the bar nuts to the recommended torque. After adjustment, perform a quick function test by manually rotating the chain and ensuring it seats snugly in the groove without binding. Always recheck tension after the first few minutes of operation, as chain temperature can cause expansion and slight changes in tension.
When replacing the bar and chain, take care to remove the bar nuts and any guards, then carefully slide the bar away from the clutch drum. Inspect the bar for excessive wear, burring, or heat damage; replace if grooves are worn beyond service limits or if the bar has developed straight or wide flats that could hinder proper chain alignment. Install the new bar with the correct orientation, ensuring the groove is aligned with the drive links and that the bar’s anti-kickback nose sprocket sits properly in place. Thread the chain around the bar nose and wrap it around the drive sprocket, making sure the cutting edges face forward on the top half of the bar. Reinstall the bar, snug the nuts, and set the correct tension as described previously, then run the engine briefly to confirm smooth operation and proper lubrication.
Regular inspection of the bar and chain assembly includes checking for chip wear, cracks in the bar body, and signs of excessive chain stretch. Look for equal wear along the entire length of the chain to ensure even cutting performance; if the drive links appear elongated or the rivets show signs of looseness, the chain should be replaced rather than tightened beyond safe limits. Remember to clean the bar groove and oiling holes to prevent clogging, and ensure the oiling system is delivering lubricant effectively to the bar nose during operation. Adhering to recommended service intervals and using only STIHL-recommended chains and bars will extend the life of the cutting system and improve overall performance while maintaining safety standards.
When performing bar and chain work in a workshop or outdoor environment, maintain a clean, well-lit workspace with a stable surface. Use gloves to protect hands from sharp cutting edges and to prevent dirt from contaminating the chain pitch or bar groove. After completing any adjustment or replacement, perform a controlled test cut on a scrap piece of wood to verify that the chain tracks correctly, the bar remains square to the drive sprocket, and there is no unusual vibration or noise. Document any deviations observed during testing and consult the service manual or a qualified technician if issues persist. This disciplined approach ensures reliable performance and reduces the risk of injury during subsequent cutting tasks.
Note: Always follow the manufacturer’s torque specifications for bar nuts and the chrome-plated tensioning screw. Improper torque can lead to bar misalignment, chain derailment, or gear damage.
