Filling Chain Oil Tank English / USA Checking Chain Lubrication If special chain lubricant is not available, you may - in an emergency - use an HD single grade or multigrade engine oil with a viscosity that suits the prevailing outside temperature. Do not use waste oil! Medical studies have shown that renewed contact with waste oil can cause skin cancer. Moreover, waste is environmentally harmful! Waste oil does not have the necessary lubricating properties and is unsuitable for chain lubrication. : Thoroughly clean the oil filler cap and the area round it to ensure that no dirt falls into the tank. : Remove the filler cap. : Refill the chain oil tank every time you refuel. : Close the filler cap. Oil pumps with a slot in the adjusting screw have a higher flow rate (special option). It is necessary to check and refill the oil tank more often - see chapter on "Oil Quantity Control". There must still be a small amount of oil in the oil tank when the fuel tank is empty. If the oil level in the tank does not go down, the reason may be a problem in the oil supply system: Check chain lubrication, clean the oilways, contact your servicing dealer for assistance if necessary. STIHL recommends that you have maintenance and repair work performed only by a STIHL servicing dealer. 001BA158 KN 143BA024 KN The saw chain must always throw off a small amount of oil. Never operate your saw without chain lubrication. If the chain runs dry, the whole cutting attachment will be irretrievably damaged within a very short time. Always check chain lubrication and oil level in tank before starting work. Every new chain has to be broken in for about 2 to 3 minutes. After breaking in chain, check chain tension and adjust if necessary - see "Checking Chain Tension". MS 460, MS 460 R 31
