the
same
as

ADJUSTING
TABLE
ROLLS
Your
planer
is
supplied
with
two
table
rolls
(A)
Fig,
57,
which
aid
in
feeding
the
stock
by
reducing
friction
and
turn
as
the
stock
Is
fed
through
tiie
planer.
It
is
not
possible
to
give
exact
dimensions
on
the
proper
height
setting
of
the
table
rolls
because
each
type
of
wood
behaves
differently.
As
a
general
rule,
however,
when
planing
rough
stock
the
table
rolls
should
be
set
HIGH
and
when
planing
smooth
stock
the
table
rolls
should
be
set
LOW.
The
table
rolls
on
your
planer
are
set
for
average
planing
and
are
parallel
to
the
table
surface.
If
you
desire
to
adjust
the
table
rolls
higher
or
lower,
proceed
as
follows:
1.
Disconnect
machine
from
the
power
source.
2.
Lay
a
straight
edge
(B)
Fig.
58,
across
both
rolls
and
^
with
a
feeler
gage
(C)
as
shown,
adjust
height
of
table
rolls
by
loosening
set
screws
(D)
Fig,
57,
and
turn
screws
(E)
to
raise
or
lower
table
rolls
fA).
Table
rolls
must
also
be
adjusted
on
the
opposite
end
of
table
in
the
same
manner.
The
table
rolls
must
always
be
set
parallel
to
the
table.
