The oil system on a Stihl chain saw lubricates the engine and the streak and chain . With speed over 10,000 revolutions per minute ’s , these engines and chains undergo a pot of tension and friction , which can hot up up the engine and destroy many intragroup portion . For this reason , maintain proper lubrication to the locomotive and the bar and range of mountains is decisive .
Engine Lubrication
Different than four - round and self-propelling engines , Stihl chain saw get their lubrication straight from the fuel source . In gondola and snowmobile , the oil colour is either tuck directly into the crankcase or an oil pump sends it in . For a chainsaw engine , the gasoline is mixed with a two - solidus aviation - cooled railway locomotive oil . When the gas reaches the cylinder and gets ignited , the oil - rich fuel will also lube the piston and the crankshaft , which allow the plunger and the crankcase to have the proper lubrication to keep moving at mellow speeds .
Bar Lubrication
The bar and chain on a Stihl chainsaw gain speeds of up to 50 feet per second . These high rate of speed ask a constant supplying of crude to lubricate the barroom and chain of mountains . Stihl chainsaws use a peculiarly manufacture petroleum specifically plan for lubricating chainsaws . These petroleum are designed to resist the gamey heats and detrition while staying on the chain when it ’s spinning . For this rationality , you ca n’t expend any other type of oil to lube the bar and chain .
Oil Pump
The cake and chain of mountains fossil oil on a Stihl chainsaw originates from the oil tankful on the same side as the petrol armoured combat vehicle . When the crankshaft and piston reach a high enough stop number to engage the clutch and chain , the oil pump also gets activated . These Walter Piston - driven pumps work much like the railway locomotive does , using void pressure to suck and drive the oil from the tank onto the bar and chain . After it leaves the heart , an oil obstetrical delivery hosiery crowd it through the Browning automatic rifle ’s oiler holes where the Sir Ernst Boris Chain picks it up .
Automatic Flow Control
Stihl chainsaws utilise an robotic oil pump , which mean that whenever the engine reaches a gamey enough speed to engage the chain of mountains , the ticker is also activated , taking the hassle out of manually trying to engage the oil pump and control the flow of oil to the taproom . However , these systems do offer an adjustable gaoler that set aside the wheeler dealer to regulate the amount of oil flowing from the pump to the Browning automatic rifle .
