The
proper
amoiunt
ol chain
tension
depends
on
the'
length and type ol
guide
bar used.
The instructions
given
here are
correct
for all
lengths
of bars
up to
20 inches.
The lension
for hard-nose
bars
must be
looser than
that
for sprocket
nose bars.

make the
tension so
that
the
chain
is
snug against
the bar
without
causing
binding
bul
can still
be
pulled
around
the
guide
bar
by hapd.
When
hot
from operation,
the
chain
may sag away
from
the bar
a bit,
but this
sag should
not be allowed
to exceed Va"
as
measured
in
method
A. This applies
to either
type
of
bar nose.
When
adjusting
the chain
tension,
always
hold
up the
tip of
the bar
lo
take up any
play
between
the bar
mounting
slot
and
the
mounting bolts.
Keep
the
nose
up until
iension
has been
set and
the
mounting
nuls
tightened
to lock
the bar
at that
tension.
After
setting
tension,
pull
the chain
along
the
bar
several
time-s,
then
reiheck
the tension
as this"may
have
relieved
some of
the stiffness
in
the new
chaial
and
bar assembly.
t
Start
and
run
the engine

part

so the
chain
rotates
slowly
around
the
bar. Alter
one
or two
min-
utes,
stop engine
and
readiust
tension
if chain
is
now
too
loose.
Now
the
chain
and bar
assembly
is ready
for culting'
But after
each
few cuts
you
will find
the
new chain
loose and
again
in
need of tensioning.
However,
this
"stretching'i
of new

will slow
up and
virtually
cease

half-hour
or so of
