Before Starting - Stihl MS 170 Notice D'emploi

Fold the grip flush with the
top of the cap. If the grip
does not lie completely
flush with the cap and the
detent on the grip does
not fit in the
corresponding recess in the filler
opening, the cap is not properly seated
and tightened and you must repeat the
above steps.

!
Warning!
Unit vibrations can cause an improperly
tightened fuel filler cap to loosen or
come off and spill quantities of fuel. In
order to reduce the risk of fuel spillage
and fire, tighten the fuel filler cap by
hand as securely as possible.
The screwdriver end of
the STIHL combination
wrench or other similar
tool can be used as an aid
in tightening slotted fuel
filler caps.
See "Fueling" chapter in your instruction
manual.

Before Starting

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 throttle trigger, throttle
trigger interlock, stop switch and cutting
tool. The throttle trigger must move
freely and always spring back to the idle
position. Never attempt to modify the
controls or safety devices.
!
Warning!
Never operate your power tool if it is
damaged, improperly adjusted or
maintained, or not completely or
securely assembled.
!
Warning!
Check that the spark plug boot is secure
– a loose boot may cause arcing that
could ignite combustible fumes and
cause a fire.
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 sections on
"Specifications," and "Kickback".
!
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
manual. 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, shut off the engine and
then tighten. Never try to adjust the
chain while the engine is running!
Keep the handles clean and dry at all
times; it is particularly important to keep
them free of moisture, pitch, oil, fuel mix,
grease or resin in order for you to
maintain a firm grip and properly control
your power tool.
