SMCS Code: 4197; 4198-025; 4198-040
Periodic adjustment of the track tension is necessary
in order to avoid damage to the tracks. If a track is
too loose, the track will be more likely to come off
of the machine.
Track guides are recommended if the machine will
be operated in very rough terrain. Track guides are
recommended for the 267 and 277 if the machine will
be frequently operated on side slopes or very rough
terrain.
NOTICE
Do not overtigh
ten the tracks. Tracks that are too tight
can cause premature failure of the tracks. Tracks that
are too tight can cause power loss and bearing fail-
ures.
