English
Properly secure your chain saw to
prevent turnover and damage to the
chain saw.
Before Operation
Take off the chain guard (scabbard) and
inspect the chain saw for proper
condition and operation. (See the
maintenance chart near the end of the
instruction manual.)
WARNING
Always check your chain saw for proper
condition and operation before starting,
particularly the trigger switch, trigger
switch lockout, front handle guard and
cutting attachment. The trigger switch
and the trigger switch lockout must
move freely and always spring back to
the stop position. Ensure that the trigger
switch will not engage when the trigger
switch lockout is not pressed. Never
attempt to modify the controls or safety
devices.
To reduce the risk of injury, never use a
saw if any part is damaged or does not
function properly. Take the saw to your
local STIHL servicing dealer. Do not use
the saw until the problem has been
rectified.
For proper assembly of the bar and
chain follow the procedure described in
the chapter "Mounting the Bar and
Chain" of your instruction manual.
STIHL Oilomatic saw chain, guide bar
and sprocket must match each other in
gauge and pitch. Before replacing any
bar and chain, see the chapter entitled
"Specifications" in the instruction
manual and the chapter "Reactive
Forces including Kickback."

Since longer bars add weight and may
be more difficult to control, select the
shortest bar that will meet your cutting
needs.
WARNING
Proper tension of the saw chain is
extremely important. In order to avoid
improper setting, the tensioning
procedure must be followed as
described in your manual. Always make
sure the hexagonal nut(s) for the
sprocket cover is (are) tightened
securely after tensioning the saw chain
in order to secure the bar. Never start
the chain saw with the sprocket cover
loose. Check saw chain tension once
more after having tightened the nut(s)
and thereafter at regular intervals
(whenever the saw is shut off). If the saw
chain becomes loose while cutting,
switch off the motor and engage the
chain brake by moving the front hand
guard to ƒ, remove the battery from the
chain saw and then tighten. Never try to
adjust the saw chain while the motor is
running!
WARNING
After adjusting a saw chain, let the motor
run for a while, then switch motor off and
engage the chain brake by moving the
front hand guard to ƒ. Remove the
battery from the chain saw and recheck
saw chain tension. Proper saw chain
tension is very important at all times.
Keep the handles clean and dry at all
times; it is particularly important to keep
them free of moisture, pitch, oil, grease
or resin in order for you to maintain a firm
grip and properly control your chain saw.
Check contacts in battery compartment
for foreign matter. Keep clean.
Fit the battery correctly – it must engage
audibly.
WARNING
Before disengaging the chain brake and
switching on your chain saw, be sure
that the guide bar and saw chain are
clear of you and all other obstructions
and objects, including the ground. If the
upper quadrant of the tip of the bar
touches any object, it may cause
kickback to occur (see section on
reactive forces). Never attempt to start
the chain saw when the guide bar is in a
cut or kerf.
For specific starting instructions, see the
chapter "Switching On" of your
instruction manual.
