Warnings and Instructions
WARNING
■ There are no user-authorized repairs for the
chain saw. To reduce the risk of fire or other
personal injury and property damage:
► Users may carry out only the cleaning and
maintenance operations described in this
manual.
► Strictly follow the cleaning and maintenance
instructions in the appropriate sections of
this instruction manual.
► STIHL recommends that all repair work be
performed by authorized STIHL servicing
dealers.
■ To reduce the risk of personal injury and prop‐
erty damage from unintentional starting:
► Shut off the engine and engage the chain
brake by moving the front hand guard for‐
ward before inspecting the chain saw or
carrying out any cleaning, maintenance or
repair work. Always shut off the engine
before storing the chain saw, and any other
time it is not in use.
■ Proper maintenance will help maintain cutting
performance and reduce the risk of personal
injury caused by chain derailment and reactive
forces.
► Wear gloves when handling the saw chain.
► Keep the chain, guide bar and sprocket
clean.
► Replace the chain and guide bar when they
become worn or damaged.
► Keep the chain sharp and at proper tension.
► Tighten all nuts, bolts and screws after
each use.
■ Like an automobile brake, the chain brake on
your chain saw incurs wear each time it is
engaged. In order for the chain brake on your
STIHL chain saw to function properly, it must
be properly maintained. Return the chain saw
to your STIHL servicing dealer for periodic
inspection and servicing of the brake system
according to the following schedule:
– Heavy Usage: every 3 months
– Moderate Usage: every 6 months
– Occasional Usage: every 12 months
■ Return the chain saw immediately for mainte‐
nance whenever the brake system cannot be
thoroughly cleaned or there is a change in its
operating characteristics.

8 Maintenance, Repair and Storage
■ Use of parts that are not authorized or
approved by STIHL may cause serious or fatal
injury or property damage.
► STIHL recommends that only identical
STIHL replacement parts be used for repair
or maintenance.
■ Improper storage can result in unauthorized
use, damage to the chain saw and an
increased risk of fire and other personal injury
or property damage.
► Shut off the engine and engage the chain
brake by moving the front hand guard for‐
ward before storing.
► Store the chain saw indoors in a dry, secure
place that cannot be accessed by children
or other unauthorized users.
NOTICE
■ Always release tension on the chain after fin‐
ishing work. The chain contracts as it cools
down. If it is not slackened, it can damage the
drive shaft and bearings. Properly re-tension
the chain before using the saw again.
