STIHL MS 170 180 Chainsaw Owners Manual

English / USA
Mounting the Bar and Chain
(Front chain tensioner)
For the proper and effective operation of
the chain brake, the brake band and
clutch drum must be kept free of dirt,
grease and other foreign matter which
may reduce friction of the band on the
drum.
!
Warning!
Do not operate your chainsaw if the
muffler is damaged, missing or modified.
An improperly maintained muffler will
increase the risk of fire and hearing loss.

If your muffler was equipped with a
spark-arresting screen to reduce the risk
of fire, never operate your saw if the
screen is missing or damaged.
Remember that the risk of forest fires is
greater in hot or dry weather.
For these reasons, each STIHL
chainsaw should be returned to trained
personnel such as your STIHL servicing
dealer for periodic inspection and
servicing of the brake system according
to the following schedule:
Heavy usage - every three months,
Moderate usage - twice a year,
Occasional usage - annually.
You can run chains of different pitches
on this chainsaw  – depending on the
chain sprocket (see “Specifications”):
Keep the chain, bar and sprocket clean;
replace worn sprockets or chains. Keep
the chain sharp. You can spot a dull
chain when easy-to-cut wood becomes
hard to cut and burn marks appear on
the wood. Keep the chain at proper
tension.
The chain pitch (1) must match the pitch
of the sprocket and the guide bar (for
Rollomatic). The drive link gauge (2)
must match the bar groove width (3).
The chainsaw should also be returned
immediately for maintenance whenever
the brake system cannot be thoroughly
cleaned or there is a change in its
operating characteristics.
The pitch is marked on the chain
sprocket and guide bar in inches
(e.g. 3/8 or .325). The groove width
is marked on the guide bar in
millimeters (e.g. 1.6).
Tighten all nuts, bolts and screws except
the carburetor adjustment screws after
each use.
For any maintenance of the emission
control system please refer to the
maintenance chart and to the limited
warranty statement near the end of the
instruction manual.
!
Warning!
If non-matching components of the
wrong pitch or drive link gauge are
run together on the same machine
they may be damaged beyond
repair after a short period of
operation.
In order for the chain brake on your
STIHL chainsaw to properly perform its
function of reducing the risk of kickback
and other injuries, it must be properly
maintained. Like an automobile brake, a
chainsaw chain brake incurs wear each
time it is engaged.
Store chainsaw in a dry place and away
from children. Before storing for longer
than a few days, always empty the fuel
tank (see chapter "Storing the Machine"
in the instruction manual).
The amount of wear will vary depending
upon usage, conditions under which the
saw is used and other factors. Excessive
wear will reduce the effectiveness of the
chain brake and can render it
inoperable.
