1). Remove side cover, bar and chain.
2). Using a screwdriver, putty knife, wire brush or other
similar instrument, clear residue from the rails on the guide
bar. This will keep the oil passages open to provide proper
lubrication to the bar and chain.(See Fig.30)
3). Reinstall the bar, chain (and adjust tension), sprocket
cover and bar bolt retaining muts. (See Section Guide bar/
saw chain installation)
4. 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 resuiting in uneven bar wear. As the
bar wears univenly, 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 willl contribute to repid bar wear(see Section
Chain maintenance instructions). To help minimize bar wear,
the following guide bar maintenance is recommended.
5. 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
discharege 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.

3. Clean Guide Bar Rails
Warning! Unless you have experience and
specialized training for dealing with kickback (see
Safety Precautions), always use a low-kickback saw
chain, which signicantly reduces the danger of kickback.
Low-kickback saw chain does not completely eliminated
kickback. A low-kickback or “safety chain”, should never be
regarded as total protection against injury.
A low-kickback saw chain should always be used in
conjunction with other kickback protection vices such as the
chain brake/Hand Guard furnished with your unit. Always
use a replacement saw chain designed as “low-kickback”
or a saw chain which meets the low-kickbackperformance.
A standard saw chain (a chain which soes not have the
kickback reducing guard links) should only be used by an
experienced professional chain saw operator.
