5 IMPORTANT SAFETY INSTRUCTIONS
5.6

Using the Chain Saw

5.6.1 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 chain, @ 10.2.1.
￭ The chain, guide bar and sprocket must match each other
in gauge and pitch. Before mounting or replacing:
– Read the information on guide bar and chain
combinations, @ 25.
– Read and follow the instructions on kickback and
other reactive forces, @ 6.
– 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 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,
@ 10.3.
– Always make sure the chain sprocket cover is
tightened securely after tensioning the chain in order
to secure the bar. Never start the chain saw with the
chain sprocket cover loose or missing.
– Check chain tension once more after tightening the
chain sprocket cover.
– After adjusting the chain, let the motor run for a
minute or two, then shut off the engine, engage the
chain brake and recheck chain tension.
– Check chain tension periodically thereafter at
regular intervals (only after engaging the chain brake
and shutting off the engine).

– Never cut with a loose chain. If the chain becomes
loose while cutting, engage the chain brake and shut
off the engine before tightening the chain. Never
attempt to adjust the chain while the engine is
running.
￭ To reduce the risk of fire and explosion:
– Check fuel system for leaks, especially the visible
parts, (e.g., filler cap, hose connections).
– Securely mount the spark plug boot on the spark
plug.
– Do not start the engine if the fuel system has leaks
or the saw is otherwise damaged. Have the chain
saw repaired by an authorized STIHL servicing
dealer before using it.
￭ Using a chain saw that is modified, 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 modified,
damaged, improperly maintained or not completely
and securely assembled.
– Always check your chain saw for proper condition
and operation before starting work, particularly the
throttle trigger, throttle trigger lockout, Master
Control Lever, front hand guard, chain brake and
cutting attachment.
– Ensure that the throttle trigger and throttle trigger
lockout move freely and always spring back to the
idle position when released. The throttle trigger must
not engage until the throttle trigger lockout is
depressed. The Master Control Lever must move
easily to STOP.
– Never attempt to modify or override the controls or
safety devices in any way.
– If your saw or any part is damaged or does not
function properly, take it to your authorized STIHL
servicing dealer. Do not use the saw until the
problem has been corrected.
