Remove the battery from
the power tool. This
avoids the risk of the
motor starting
unintentionally.
It may be carried only in a horizontal
position. Grip the front handle in a
manner that the machine is balanced
horizontally. Keep the cutting
attachment behind you.
Before Starting Work
Take off the chain guard (scabbard) and
inspect the saw for proper condition and
operation. (See the maintenance chart
near the end of the instruction manual.)
Warning!
Always check your power tool for proper
condition and operation before starting,
particularly the trigger switch, trigger
switch lockout, front hand guard and
cutting tool. The trigger switch and the
trigger switch lockout must move freely
and always spring back to the idle posi-
tion. Ensure that the trigger switch will
not engage when the trigger switch lock-
out is not pressed. Never attempt to
modify the controls or safety devices.

Warning!
Never operate your power tool if it is
damaged, improperly adjusted or main-
tained, or not completely or securely
assembled.
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 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 section "Kickback" and
the "ANSI B175.1-2000 chain saw
kickback standard" below.
Warning!
Proper tension of the chain is extremely
important. In order to avoid improper
setting, the tensioning procedure must
be followed as described in your man-
ual. Always make sure the hexagonal
nut(s) for the sprocket cover is (are)
tightened securely after tensioning the
chain in order to secure the bar. Never
start the saw with the sprocket cover
loose. Check chain tension once more
after having tightened the nut(s) and
thereafter at regular intervals (whenever
the saw is shut off). If the chain
becomes loose while cutting, switch off
the motor, remove the battery and then
tighten. Never try to adjust the chain
while the motor is running!
Warning!
After adjusting a chain, start the saw, let
the motor run for a while, then switch
motor off and recheck chain tension.
Proper 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 power
tool.
Check contacts in battery compartment
for foreign matter. Keep clean.
Fit the battery correctly – it must engage
audibly.
For specific starting instructions, see the
appropriate section of your instruction
manual.
