6 IMPORTANT SAFETY INSTRUCTIONS
– Do not link (chain) extension cords.
6.6 Using the Chain Saw
6.6.1 Before Operation
WARNING
■ Misuse 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,
23.
– 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,
11.3.
– 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. Disconnect the chain saw from the
power supply and recheck chain tension.
– Check saw chain tension periodically thereafter at
regular intervals (only after engaging the chain brake
and disconnecting the chain saw from the power
supply).
– Never cut with a loose chain. If the saw chain
becomes loose while cutting, switch off the motor,
engage the chain brake and disconnect the chain
saw from the power supply before tightening the
chain. Never attempt to adjust the saw chain while
the chain saw is connected to the power supply.
■ Using a chain saw that is modified, damaged, improperly
adjusted 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, particularly the trigger switch, trigger
switch lockout, front hand guard, chain brake and
cutting attachment.
– Ensure that the trigger switch and trigger switch
lockout move freely and always spring back to the
locked position when released. The trigger switch
must not engage until the trigger switch lockout is
depressed.
– Never attempt to modify or override the controls or
safety devices.
– 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.
