STIHL MS 250 Basic TUNE-UP
STIHL MS 250 chainsaw is very common for homeowners and pros. Here are 4 simple and basic tune-ups for STHIL MS 250 chainsaw.
1.Swing the knob to the left side
2.Make sure your choke is in the down position
3.Take off the cover
4.Blow off the debris and sawdust from the inside if necessary
5.Take off the air filter and the air filter housing
6.Take off the spark plug boot as well as the spark plug
7.Reinstall the new spark plug on your MS 250
8.Put the spark plug boot back on
After finishing that, you can replace the air filter by the way. Check the condition of the air filter, and clean or replace it if necessary.
Before you tune up your fuel filter, you’d better put on gloves and use a hook or something like this to put out the fuel filter. Grab and hold it, take it off and install the new filter. And pop it back on the fuel tank. And do not forget to add fresh gas and put the fuel cap back on.
Due to the friction between the rails and the downside of the strips, the rails will wear away over time, making the groove shallower. If the groove depth is too shallow, the heels of the drive links will scrape along the groove which has a negative impact on the smoothness of the chain. So check the condition of the bar, fill or just replace it if it has been worn out badly.
Except for the damage to the chainsaw chain itself, the chains under normal use are destined to wear and tear over time. There are obvious wear marks on every tooth of the Stihl chains.
It is necessary to replace the chain when the wear marks have been reached. And if you sharpen over the marks, the chainsaw will perform with a limited cutting ability and efficiency next time.
Typically all the teeth and the depth gauge marks should be reached at the same time. If it is not the case for you, you may have sharpened the chain in the wrong way which will result in different depth gauges, leading to dramatic vibration and poor cutting efficiency.
There are also wear marks along the downside of the teeth, under the rivets, and above the heel of the drive links. If the chainsaw has run out of oil or there is something wrong with the lubricating system, the increased friction will cause premature wear to the bottom part of the teeth. Replace the chain if the underside wear mark has been met.
