6 IMPORTANT SAFETY INSTRUCTIONS
components may no longer function properly and safety
devices may be inoperative. To reduce the risk of personal
injury and property damage:
– Take the chain saw and battery to your authorized
STIHL servicing dealer to be checked before further
operation.
￭ Genuine STIHL replacement parts are specifically
designed to match your chain saw and meet safety and
performance requirements. 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.
6.5 Using the Chain Saw
6.5.1 Before Operation
WARNING
￭ Misuse or unauthorized use may result in personal injury
and property damage.
– Use the chain saw only as described in this
instruction manual.
￭ For proper assembly of the bar and chain:
– Read and follow the instructions on mounting the
guide bar and saw chain,
￭ The saw chain, guide bar and sprocket must match each
other in gauge and pitch. Before mounting or replacing:
– Read the information on guide bar and saw chain
combinations,
27.
– Read and follow the instructions on kickback and
other reactive forces,
– Select the shortest bar that will meet your cutting
needs. Longer bars add weight and may be more
difficult to control.
￭ Proper tension of the saw chain is extremely important to
maximize cutting performance and reduce the risk of
personal injury from chain breakage, derailment or
reactive forces:
– Read and follow the chain tensioning instructions,
– Always make sure the chain sprocket cover is
tightened securely after tensioning the saw chain in
order to secure the bar. Never start the chain saw
with the chain sprocket cover loose or missing.
– Check saw chain tension once more after tightening
the chain sprocket cover.
– After adjusting the saw chain, let the motor run for a
minute or two, then switch the motor off and engage
the chain brake. Remove the battery and recheck
chain tension.
– Check saw chain tension periodically thereafter at
regular intervals (only after engaging the chain brake
and removing the battery).
– Never cut with a loose chain. If the saw chain
becomes loose while cutting, switch off the motor,
engage the chain brake and remove the battery from
the chain saw before tightening the chain. Never
attempt to adjust the saw chain while the battery is
inserted.
￭ Using a chain saw that is damaged, improperly adjusted
or maintained, or not completely and securely assembled
can lead to a malfunction and increase the risk of serious
personal injury or death.
– Never operate a chain saw that is damaged,
improperly maintained or not completely and
securely assembled.
– Always check your chain saw for proper condition
and operation before starting work, particularly the
trigger switch, trigger switch lockout, front hand
guard, chain brake and cutting attachment.
