GUIDE BAR
Reverse the bar occasionally to prevent partial wear.
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. (F29)
