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,

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.
