The chain must
be
tensioned after initial assembly
and
retensioned during
cutting work.
To
retension the chain, first slacken off
the hexagon nuts
(2). Insert screwdriver
end of combination
wrench through
hole
in chain sprocket cover.
Hold the bar
nose (10) up and turn the adjusting
screw
(lateral chain
tensioner) or tensioning
screw (front chain
tensioner)
clockwise with the screwdriver
until the chain
lies against
the
underside of the bar. While
still holding the
28
bar
nose up, firmly tighten down the hexagon nuts
(2).
The Oilomatic chain is correctly tensioned when it fits
snugly against the underside of the bar
but can still be
pulled easily along the bar by hand (with chain brake dis-
engaged).
Important: Wear protective gloves when per-
forming
this work.
Proper
chain
tension
and
lubrication
are
critically impor-
tant
for the cutting performance and service life of your
whole cutting attachment. Always check chain lubrication
before
starting work.
Chain tension should be checked frequently during
cutting
work and corrected as necessary. For further details see
Chapter "Bar, Chain and Sprocket".
