MAINTENANCE AND CLEANING
Chain tension is correct when, with some
effort, with a gloved hand you are able to
pull the chain smoothly around the bar
The chain should touch the underside of
the bar rail (Fig 30)
FIG. 30
During its early life use, run the chain saw,
not cutting for a minute or two, making
sure the chain is getting a good supply of
oil Stop the motor and check the chain
tension If it has loosened, readjust
After a short period of use, allow the
chain to cool and once again recheck the
tension (remove the battery first) Watch
tension carefully for the first half-hour
of use and periodi cally throughout the
life of the chain, readjusting as required
when the chain and bar are cool to the
touch Never tighten chain when it is hot
Lubricate the chain properly with
OREGON® brand bar and chain oil It has
been specially formulated to maximise
power and reduce friction Make certain
the chain is getting an adequate supply
of oil Oil should be thrown from the nose
of the bar when the chain saw is running,
but not in the cut
Saw chain will stretch as a result of
normal use, but insufficient oil, aggressive
use, or failure to perform recommended
maintenance can lead to premature
stretching
