Breaking in a New Saw Chain A new chain and bar will need chain readjustment after as few as 5 cuts. This is normal during the break-in period, and the interval between future adjustments will begin to lengthen quickly. Chain Lubrication Always make sure the automatic oiler system is working properly. Keep the oil reservoir filled with Chain, Bar and Sprocket Oil. Adequate lubrication of the bar and chain during cutting oper ations is essential to minimize friction with the guide bar. Never starve the bar and chain of lubricating oil. Running the saw dry or with too little oil will decrease cutting efficiency, shorten saw chain life, cause rapid dulling of chain, and lead to excessive wear of bar from overheating. Too little oil is evidenced by smoke or bar discoloration. Chain Sharpening Chain sharpening requires special tools to ensure that cutters are sharpened at the correct angle and depth. For the inexperienced chain saw user, we recommend that the saw chain be professionally sharpened by the nearest Authorized Service Center. If you feel comfortable sharpening your own saw chain, special tools are available from your Authorized Service Center. Use 3/16” round file to sharpen this chain.
