screws
(D in Fig. 1).
Both screws
must be tightened
with a wrench
when
the desired
angle
is reached.
Work Table
The adjustable
work
table
can
be
placed
in two
positions
on the machinein
front of sanding
disc or
in front of the sanding
belt when
sanding
belt is in a
vertical
position.
It can also be used in the latter
loca-
tion as a rest when the sander
is operated
horizontal-
ly.
To ad}ust the table
to make
a right angle
with the
disc hold a try square
with one leg against
the disc
and one leg on the table.
Screw
the knob
(A in Fig.
1) in or out until the square
rests evenly against
both
surfaces.
Bring the
inside
nut
on the stud
against
the table
and
then
tighten
the second
nut
securely
against
the inner
nut.
To adjust
the table
at the lower
stop unscrew
the
knob until the table
rests on the work table
support.
Using
a bevel
set at 45 ° with one side
against
the
disc and the other
on the table, turn the square
head
set screw
in the yoke support
in or out until the two
sides of the bevel rest on both surfaces.
Then tighten
the locking
nut.

OPERATION
The idler pulley
on this sander
is rubber
covered
and can be used
for drum sanding
as shown
in Fig.
3, Long pieces
may be finished on this sander
by re-
moving
the fence and, if necessary,
the disc.
The sanding
of metals
or plastics
require
aluminum
oxide
belts.
The
belt
supplied
on the tool
is for use
on wood.
It is preferable
to sand
with the grain.
Cross grain
sanding
will show sanding
marks.
To produce
a fine
finish it is advisable
to oscillate
the material
across
the belt slowly.
In this way marks in either direction,
lengthwise
or across,
the
grain,
are
reduced
to a
mimmum.
The lower
side of the belt may be used as a flexi-
ble belt sander,
particularly
with the table
in a verti-
cal position.
For butt
sanding
on the belt
use the
fence as a stop.
Both straight
and compound
angles
Protractor
The adjustable
pointer
may
be reset
at any
time
that
the protractor
becomes
out of adjustment
To
correct
the
reading
loosen
the
knurled
knob,
hold
head
and bar against
a try square
and retighten
the
knob.
Then reset the pointer
to the 90 ° mark.
SPEED
The correct
operating
range
for this sander
is from
1200 to 1600 RP.M.
Use
2" diameter
hubless
pul-
!eys to obtain
this speed
with a 1750 R.P.M motor.
A 1750 R,P.M,
1/3 H.P, motor
is recommended
for
ordinary
work,
A 1/2 H.P. motor is recommended
for
heavy
duty on production
operations,
Fig. 3
may be sanded
with the aid of the protractor
and the
angle
adjustment
of the work table.
To replace
the abrasive
on the disc
remove
the
complete
disc and soak in hot water.
The paper can
then be peeled
off. Be sure metal
disc is dry before
cementing
the new abrasive,
While a guard
for the "V" belt is not supphed,
due
to the variety
of possible
installations,
it is strongly
recommended
that suitable
protection
be provided
by
the operator.
