Solo USA 280 ユーザーズマニュアル

MS 270, MS 270 C, MS 280, MS 280 C

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. 

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. 

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.

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.

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).

You can run chains of different pitches 
on this chainsaw  – depending on the 
chain sprocket (see “Specifications”):

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 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).

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.

:

Unscrew the nuts and take off the 
chain sprocket cover.

:

Turn screw (4) counterclockwise 
until the tensioner slide (5) butts 
against left end of housing slot.
