UNPACKING AND ASSEMBLY
AA 1214 - F/N 573259
Tighten the chain tensioning ring until
the lowest cutters underneath the bar
contact the bar rail (Fig. ).
Saw chain tension is correct when, with
some effort, a gloved hand can pull the
chain smoothly around the bar. The
chain should touch the underside of the
bar rail (Fig. ).
Tighten the side cover release knob.
After a short period of use, allow the
chain to cool, remove the battery and
check the tension again. Watch tension
carefully for the first half-hour of use
and periodically throughout the life of
the chain readjusting as required when
the chain and bar are cool to the touch.
Never tension chain when it is hot.
Chain will stretch as a result of normal
use, however, insufficient oil, aggressive
use or failure to perform recommended
maintenance can lead to premature
stretching.
