SPEED
For best perf ormance this tool should run at 8p-
proximately 2700 R.P.M. This speed is attained by
using a 2 inch diameter motor pulley with a Yz inch
V-groove.
Be sure to specify the shaft diameter of your motor
when ordering the motor pulley.
BETT
Use a standard % inch V-belt. To determine the
belt length place rhotor and tool in operati.g posi-
tion and measure around the outside of the pulleys
with a steel tape. Do not measure in the grooves.
TUBRICATION
This sander is equipped with precision type, sealed
ball bearings. These bearings were packed with
grease at the factory and require no additional lubri-
cation for the life of the bearing.
To maintain smooth and easy operation of the
controls, oil the following parts occasionally with any
good grade machine oil:
| . Belt adjusting knobs Nos. 23 and 33 where
they enter the casting.
2. Pulley support pins Nos. 25 and 29 where they
enter the casting.
coNTROTS
The sanding belt may be raised from horizontal to
vertical position after loosenittg the two belt table
pivot lock bolts, No. I 0. Always tighten these bolts
securely before operation in any position.
The belt adjustir,g knobs align the iCler pulley, No.
27 , to keep the sanding belt running true over. the
pulleys and centered on the belt table. These knobs
also control the tension of the sanding belt.
The table tilt lock knob locks the work table at any
desired degree of tilt from 0o to 45".
The belt table fence provides a backup for the
work piece when using the sanding belt.

2. Apply belt tension by turning the two belt ad-
justing knobs clockwise. While applying ten-
sion keep the idler pulley approximately p?r-
allel with the drive pulley. When proper ten-
sion has been applied you should be able to
deflect the belt, as shown in Fig. 2, ErpproX-
imately Yz of an inch.
Align the sanding belt so that it will track on the
approximate centers of the two pulleys and remain in
one position on the pulleys, as follows:
| . Rotate the belt bv hand in the correct direc-
tion, as shown in Fig. | .
2. If the belt tends to run off to the right, turn
the right hand knob clockwise. If the belt tends
to run off to the left, turn the left hand knob
clockwise.
3. Recheck the belt tension and adjust if fi€c€s-
sary by turning both knobs an equal amount.
4. The tool should now be ready to operate. If,
under power, the belt does not track propetly,
make very minor adjustment of the knobs
while the tool is in operation.
When installirg new sanding belts follow the
above steps. Be sure the arrow on the inside of the
belt points in the same direction as the rotation
arrow shown in Fig. l.
NOTE: Tighten all pulley set scre\ rs after a few
hours of operation.
The work table stop screws may require adjust-
ment to obtain the 90" and 45" settings. If adjust-
ment is necessary, it may be accomplished as f ollows:
| . Loosen the table tilt lock knob, No. 5 3, and
using a combination square set the work table
exactly square with the sanding ciisc. R e-
tighten knob.
2. Loosen hex nut, No. 50, and turn the square
head set scr€w, No. 5 | , until it contacts tlre rib
on the underside of the table. Re-tighten the
hex nut, while holding screw in this ptsition.
3. Repeat the above procedure f or the 45 " stop
screw, No. 59.
CAUTION: In placing the work table assemblv on
the tool, keep the edge of the table as close as pos-
sible to the sanding surface to eliminate the J.rr-
ger of thin work becomittg wedged between the
table and the sanding surface.
The socket head set screw, No. 5 5 , secures the
table support, No. 49, to the support rod, No. 52,
and also serves as the lock stud for the table tilt lock
knob. If adjustment of this stud is necessary loosen
the tilt knob and tighten securely with the Allen
wrench provided.
The sanding belt table when used in the vertical
position should be set square with the work table, as
follows:
l. After the work table has been installed for use
with the belt, loosen the two belt table pivot
Iock bolts, No. | 0.
2. Place a combination square on the work table
and pivot the belt table until the two tables are
90" to each other.
3. Re-tighten pivot lock bolts.
This procedure must be repeated each time the
position of the belt table has been changed.
