Logs under strain:
Risk of pinching! Always start relieving
cut (1) at compression side.Then make
bucking cut (2) at tension side.
If the saw pinches, stop the engine and
remove it from the log.
Only properly trained professionals
should work in an area where the logs,
limbs and roots are tangled. Working in
"blow down" areas is extremely
hazardous. Drag the logs into a clear
area before cutting. Pull out exposed
and cleared logs first.

MAINTENANCE, REPAIR AND
STORING
Maintenance, replacement, or repair
of the emission control devices and
systems may be performed by any
nonroad engine repair establishment
or individual. However, if you make a
warranty claim for a component
which has not been serviced or
maintained properly or if
nonapproved replacement parts were
used, STIHL may deny coverage.
!
Warning!
Use only identical STIHL replacement
parts for maintenance and repair. Use of
non-STIHL parts may cause serious or
fatal injury.
Strictly follow the maintenance and
repair instructions in the maintenance
chart near the end of the instruction
manual.
!
Warning!
Always stop the engine and make sure
that the chain is stopped before doing
any maintenance or repair work or
cleaning the power tool.

!
Warning!
Do not attempt any maintenance or
repair work not described in your
instruction manual. Have such work
performed by your STIHL servicing
dealer only. For example, if improper
tools are used to remove the flywheel or
if an improper tool is used to hold the
flywheel in order to remove the clutch,
structural damage to the flywheel could
occur and could subsequently cause the
flywheel to burst.
Wear gloves when handling or
performing maintenance on saw chains.
!
Warning!
Use the specified spark plug and make
sure it and the ignition lead are always
clean and in good condition. Always
press spark plug boot snugly onto spark
plug terminal of the proper size. (Note: If
terminal has detachable SAE adapter
nut, it must be securely attached.) A
loose connection between spark plug
terminal and the ignition wire connector
in the boot may create arcing that could
ignite combustible fumes and cause a
fire.
!
Warning!
Never test the ignition system with the
spark plug boot removed from the spark
plug or with a removed spark plug, since
uncontained sparking may cause a fire.
