CORRECT JOINT
AND
CUTTING
ACTION
Maintain recommended
depth of .025 on the depth gauge.
Check your joint
reguarly.
Make
a practice of jointing your chain after every second
filing.
This will result in a
fast
cutting,
smooth operating
chain with less effort
on your part.
Visualize
your
cutters as
a
properly adjusted planer blade with ALL
depth gauges 'jointed
evenly.
(Figure
18).
EXCESSIVE
JOINT
Lack of care in jointing
may
result in
excessive
or uneven joint.
This will cause
the
cutters
to
bite
in, chain will
grab,
resulting
in overloading
of
attachments,
poor
performance
and
damage to
both chain and bar will result.
In this illustration
we
have
used
a
deep biting chisel to
convey the
action of excessive or uneven jointing
with its accompanying chain result.
(Figure
19).
INSUFFICIENT JOINT
FAILING TO
CHECK OR JOINT' REGULARLY.
Cutters
cannot bite into
the wood,
chain will not
cut efficiently or to
capacity.
This
will require
extra
pressure
on
your
part
resulting
in
excessive
wear
to the
bottom of
the cutters
and
links plus
rapid wear
to
the
cutter
bar
rails.
Again using
a
chisel
we
illustrate
the chain
at work with insufficient
joint.
