Grease point
Reverse guide bar occasionally to prevent partial wear. The bar rail should always be square. Check
for wear of the bar rail. Apply a ruler to the bar and the outside of the cutter. If a gap is observed
between them, the rail is normal. Otherwise, the bar rail is worn. Such a bar needs to be replaced.

Other Checks
Check for fuel leakage and loose fastenings and damage to major parts, especially handle joints and
guide bar mounting. If any defects are found, make sure to have them repaired before operating
the saw again. Check for cracks and for excessive wear interfering with the chain drive. If the wear
is considerable, replace it with a new one. Never fit a new chain on a worn sprocket, or a worn
chain on a new sprocket.
