11. Maintenance of Saw Chain and Guide Bar
■ 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.
