GUIDE BAR
1.Remove sawdust in the bar groove and the oiling port. (MA5)
2.Grease the nose sprocket from the feeding port on the tip of the guide bar. (MA6)
3.Periodically turn over the guide bar when mounting it to the unit, in order to prevent partial wear.
4.The bar rail should always be a square. Check for wear of the bar rail. Apply a ruler to the bar and the outside of a cutter. If a gap is observed between them, the rail is normal. Otherwise, the bar rail is worn. Such a bar needs to be corrected or replaced. (MA7)
AIR FILTER
A clogged air filter can reduce the engine performance. Daily check the filter elements and tap off attached saw dust. When cleaning, use warm, soapy water and dry completely before installing. When the element is broken or shrunk, replace with a new one. (MA8)
