Installing the Sanding Belt Fences
The sander includes two fences for use with
the sanding belt. The small fence/platen
attaches directly to the sanding belt frame,
and is used for supporting small items being
sanded.
The larger fence/platen attaches to the
small fence. It gives a larger support surface
for sanding larger work pieces
NOTE: These parts may be pre-assembled at
the time of delivery. If not, follow the
following parts assembly:
1. Install the small fence onto the
sanding belt frame with the four hex
screws and washers. See Figure 2.
Figure 2 – Install the small fence
2. Insert two Phillips head screws
through the countersunk holes in
the large fence and install the knobs
on their threaded ends. (Washers
shown in Figure 3 are optional, not
included with the sander).
3. Slide the large fence’s two screws
with knobs over the two slots in the
small fence and fasten it in place.
Depending upon the material being
sanded, the fence can easily be
removed by loosening the two
knobs and sliding it off the small
fence, See Figure 3.
Figure - 3 Install fence knobs
Installing the Disc Table
Refer to figures 4 and 5.
The larger work Table is used with the sanding
disc. It should be used to support workpieces in

INSTALLATION
Mounting the Sander
NOTE
Although compact, the sander is heavy. At
least two people are required to lift it from
the carton.
Choose a suitable location to mount the
sander. The sander must be installed in a
place with a place with ample lighting and
have the correct power supply.

8
Make sure there is plenty of room for
moving the workpiece. There must be
enough room that neither operators nor
bystanders will have to stand in line with
the wood while using the tool. Allow room
so that the belt assembly can be positioned
horizontally.
Figure 7 shows the base dimensions,
mounting holes and the required space to
allow for table assembly in the horizontal
position.
Figure 7 – Base dimension and required
space.
The sander must be bolter to a firm, level
surface. The sander can be installed on a
workbench or a tool stand using bolts, lock
washers and hex nuts. (Not Supplied).
Adjusting Disc Table Angle
Ensure the sander is disconnected from the
power source prior to commencing work.
1. To check the trueness of the 90 Deg.
Angle of the disc sanding table,
place a square or other measuring
device on the table with the other
end against the sanding disc. See
Figure 8.
Figure 8 – Checking the disc trueness.
2. Loosen the disc table adjustment
handle, and adjust the table angle to
90 Deg.
3. Re-tighten the disc table adjustment
handle.
4. Adjust the angle scale pointer to
Zero Deg.
5. To adjust the table angle to another
angle, loosen the disc table
adjustment handle.
6. Set the table at the desired angle
using the angle scale pointer.
7. Re-tighten the disc table adjustment
handle.
WARNING
To avoid jamming the workpiece or fingers
between the table and sanding surface, the

9
table edge should be set to a maximum of
1/16 inches away from the sanding
surface. See Figure 9.
Figure 9.
Adjusting the Belt Assembly
The sanding frame can be adjusted easily
between a vertical and horizontal position,
or any other position to assist your sanding
operation.
1. Loosen the hex screw that pulls the
split casting together. This will allow
the sanding belt frame to be moved
to the desired work angle. See
Figure 10.

Power Source
WARNING
All electrical connections must be
performed by an electrician.
Connect the sander to a supply circuit
protected breaker or time delay fuse.
The motor is designed for operation on the
voltage and frequency specified. Normal
loads will be handled safely not more than
10% above or below the specified voltage.
Running the unit on voltages not within the
range may cause overheating and burn-out.
Heavy loads require that the voltage at
motor terminals be no less than the voltage
specified. Power supply to the motor is
controlled by a single pole locking rocker

10
switch. Remove the key to prevent
unauthorized use.
Grounding Instructions
WARNING
Improper connection of equipment
grounding conductor can result in the risk
of electrical shock. Equipment should be
grounded while in use to protect the
operator from electric shock.
Check with a qualified electrician if
grounding instructions are not understood
or if in doubt if the tool is properly
grounded.
The tool is equipped with an approved 3-
conductor cord rated at 300V and a 3-prong
grounding type plug (See Figure 15) for your
protection against shock hazards.
Grounding plug should be plugged directly
in to a properly installed and grounded 3-
prong grounding-type receptacle, as shown
(Figure 12).
Figure 12 – 3-prong receptacle
Do not remove or alter the grounding prong
in any manner. In the event of malfunction
or breakdown, grounding provides a path of
least resistance for electrical shock.
WARNING
Do not permit fingers to touch the
terminals of the plug when installing or
removing from the outlet.
The plug must be plugged into a matching
outlet that is properly installed and
grounded in accordance with local codes
and ordinances. Do not modify the plug
provided. If it will not fit in the outlet, have
the proper outlet installed by an electrician.
Inspect the tool cords periodically, and if
damaged, have them repaired by an
authorized service facility.
Green (or green and yellow) conductor in
the cord is the grounding wire. If repair or
replacement of the electrical cord or plug is
necessary, do not connect the Green (or
green and yellow) wire to a live terminal.
Where a 2-prong wall receptacle is
encountered, it must be replaced with a
properly grounded 3-prong receptacle
installed in accordance with national
Electric Code and local codes and
ordinances.
Extension Cords
The use of any extension cord will
cause some drop of voltage and loss
of power.

11
Wires of the extension cord must be
of sufficient size to carry the current
and maintain adequate voltage.
Use the table to determine the
minimum wire size (A.W.G.)
extension cord
Use only 3-wire extension cords
having 3-prong grounding type plugs
and 3-pole receptacles which accept
the tool plug.
If the extension cord is worn, cut or
damaged in any way, replace it
immediately.
Extension Cord Length
Length Wire Size A.W.G
Up to 25 ft 18
25-50 ft 16
NOTE
Using extension cords over 50 ft long is not
recommended.

12
with the belt and with table when
sanding with disc.
Never push a sharp corner of the
workpiece against belt or disc.
Abrasive backing may tear.
Replace the abrasive belt or disc
when they become loaded (glazed)
or frayed.
WARNING
Review all safety precautions, before
turning on the machine, making sure that
you fully understand the features,
adjustments and capabilities of the
machine outlined in this manual.
ON/OFF Switch
The ON/OFF switch needs to have the
safety switch key inserted before the switch
can be used. This feature prevents
unauthorized use of the sander. See Figure
14.
Figure 14 – Remove safety key to prevent
sander use.
Abrasive Belt Sanding
Finishing flat surfaces: Hold
workpiece firmly with both hands;
keep fingers away from abrasive
belt.
Use table to position and secure
work being sanded. Keep the end
butted against the table and move
work evenly across the abrasive belt
Finishing long pieces: Use belt in
horizontal position with the work
stop. Apply only enough pressure to
allow the abrasive belt to remove
material.
Use work stop to position and
secure work being sanded. Keep the
end butted against the table and
move work evenly across the
abrasive belt. Use extra caution
when sanding very thin pieces.
Finishing curved edges: Finish
outside curves on flat portion of
abrasive belt. Finish inside curves on
the idler drum portion of the
abrasive belt.
Finishing end grain: It is more
convenient to finish the end of long
workpieces with the abrasive belt in
the vertical position.
Position the table on belt side of
sander. Move work evenly across
abrasive belt. For accuracy, use the
miter gauge. Table may be tilted for
beveled work.
Disc Sanding
Abrasive disc sanding is well suited
for finishing small flat surfaces and
convex edges.

13
Move workpiece across downside
(left) of the abrasive disc. Hold
workpiece firmly with both hands;
keep fingers away from abrasive
disc.
Abrasive disc moves fastest and
removes more material at the outer
edge.
For accuracy, use the miter gauge.
Replacing the Sanding Belt
1. Remove the plastic side cover from
the frame by unscrewing the knob.
See Figure 15
Figure 15
2. Remove the small fence. See page 3
for instructions on installing this
part.
3. Slide tension lever to the right to
release the belt tension. See Figure
16.
NOTE
Above the tension lever, there is a direction
arrow. The sanding belt must run in the
direction of this arrow so that the splice does
not come apart. See Figures 16 and 17.
4. Remove the old belt by sliding it off
to the left of the frame. Place the
new sanding belt over the drums
with the direction arrow pointing in
the proper direction. See Figure 17.
Make sure the belt is centered on
both drums.
5. Slide the tension lever to the left to
apply tension to the belt. See Figure
16.
6. Re-install the small fence and slide
cover onto frame (removed in Step 1
& 2).
7. Plug in the power cord. Turn the
switch to “ON” and note if the belt
tends to move to the right or left on
the drums. The belt should be
running on the center of the drive
drums. If it is not the belt tracking
needs adjustment. See instructions
on sanding belt tracking.
Figure 16
Figure 17

14
Belt Tracking Adjustment
Refer to Figure 18.
1. Belt tracking on the center of the
drive wheels is pre-set at the
factory. If an adjustment needs to
be made, the sander must be turned
on.
a) If the sanding belt moves toward
the disc, slowly turn the tracking
knob clockwise ¼ turn.
b) If the sanding belt moves away
from the disc, slowly turn the
tracking knob counter-clockwise
¼ turn.
2. Slowly turn the belt tracking knob
noting the belt movement. Re-adjust
the tracking knob, as necessary,
until the belt runs true in the center
of the drums.
Figure 18
Sanding Disc Installation
Refer to Figure 19.
The sandpaper disc can be removed with
the table installed, or with the table
removed to give more working access to
the disc, if needed.
1. Peel the abrasive disc from the
metal disc plate. A putty knife may
help in this process.
2. Make sure the disc plate is clean of
any residue. Mineral spirits will
soften the PSA adhesives for its
removal. Rotate the disc by hand to
access all of the disc surface.
3. Peel the protective backing from the
new PSA 9” abrasive sanding disc,
then center and press the sanding
disc firmly onto the metal disc plate.
4. Replace the sanding table if it was
removed.
