Q: Which chain to use for my JONSERED CS 2238 chainsaw?

Your JONSERED CS 2238 chainsaw uses a Jonsered H36 type chain designed to provide an excellent balance between performance and kickback reduction. Here are all the important specifications: Chain specifications: Type: Jonsered H36 Pitch: 3/8" (9.52 mm) Drive link thickness: 1.3 mm (0.050") Number of drive links: 52, 56, or 62 depending on the guide length used Compatible guide lengths: 14, 16, or 18 inches (35, 40, or 45 cm) For sharpening the chain: use a round file of 4.5 mm (5/32") with a sharpening angle of 60° , a top plate angle of 30° , and a clearance of 0° . The depth limiter gap should be maintained at 0.65 mm (0.025"). It is recommended to adjust the chip thickness every three chain sharpenings. For safe and correct sharpening, use the recommended Jonsered sharpening template. Chain tension: check the tension after each full tank of gas. The chain should be tensioned to the maximum without preventing manual rotation. A new chain requires more frequent checks during its break-in period. Insufficient tension increases the risk of breakage and wear of the guide. Inspection and maintenance: when replacing or installing a chain, systematically check that the rivets and links have no cracks, that the chain is not stiff, and that the components show no abnormal wear. Replace the chain if its tooth height is less than 4 mm. Regularly oil your chain with a special chainsaw oil that has excellent fluidity and adhesion qualities, preferably the biodegradable vegetable oil recommended by Jonsered.
