Guide bar maintenance
Most guide bar problems can be prevented mere 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
difficulty in making straight cuts. Insufficient guide bar lubrication and operating the saw with a chain this 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.
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 clear, 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.
Troubleshooting
Symptom
Chain saw fails to operate
Chain saw operates intermittently
Dry chain
Kickback Brake / Run-down brake

WARNING! Never use tools with defective On/Off switches or defective kickback brake (hand guard).
WARNING! If the chain saw does not perform properly, or sound are abnormal, or motor cannot be started, or stopped as described, or the chain brake does
not work properly, or any other irregularity, or malfunction occurs, do not attempt to repair the chain saw by yourself.
