Guide bar maintenance
Most guide bar problems can be prevented merely by keeping the
chain saw well maintained.
Incorrect filing and non-uniform cutter and depth gauge settings
cause most guide bar problems, primarily resulting in uneven bar
wear. As the bar wears unevenly the rails widen, which may cause
chain clatter and difficuhy in making straight cuts.
Insufficient guide bar lubrication and operating the saw with a chain
that is TOO TIGHT will contribute to rapid bar wear (see Section
CHAIN MAINTENANCE INSTRUCTIONS).
To help minimize bar wear, the following guide bar maintenance is
recommended.
GUIDE BAR - The bar should be reversed every 8 working hours to
ensure uniform wear. Keep the bar groove and lubrication hole dean
using the bar groove cleaner supplied optional.
BAR WEAR - Tum guide bar frequently at regular intervals(for
example, after 8 hours of use), to ensure even wear on top and
bottom of the bar.
BAR GROOVES - Bar grooves (or rails which support and carry the
chain) should be cleaned if the saw has been heavity used or if the
saw chain appears dirty. Rails should always be cleaned every time
the saw chain is removed.
OIL PASSAGES - Oil passages at bar pad should be cleaned to
ensure proper lubrication of the bar and chain during operation.
This can be done using a soft wire small enough to insert into the oil
discharge hole.
NOTE: The condition of the oil passages can be easily
checked. If the passages are clean the chain will
automatically give off a spray of oil within seconds of
starting the saw. Your saw is equipped with an automatic
oiler system.
