MOUNTING THE SANDER
TO A WORKBENCH OR STAND
CAUTION: If during operation there is any
tendency for the sander to tip over, slide or walk
on the supporting surface, the sander should be
properly mounted to a workbench or stand.
1. Rubber feet are fastened to this sander prior
to shipping. They may, or may not, be used when
attaching the sander to a bench or stand.
2. Position the sander on the workbench.
3. There are two options for mounting the sander
to the workbench:
- Use the two extra holes in the base (located by
the front right foot, and rear left foot when looking
at the sanding belt table);
- Use the four holes that are securing the
rubber feet. The bolts will have to be removed
and replaced with other fasteners to go through
the sander’s base and feet. See Figure 15 for
illustrations of each method.
4. Mark the workbench through the selected
mounting holes located in the sander’s base, per
above.
5. Drill holes in the workbench at the marks.
6. Using long bolts, washers, lock-washers and
nuts; or lag bolts; (fasteners not supplied), secure
the sander to the workbench. FIG. 15.
Always ensure the sander is
unplugged prior to attempting any assembly,
installation or changing of parts and accessories.
TEST RUNNING THE SANDER
With the sander fully assembled and checked
to make sure that all parts and fasteners are
secure, test run the sander to conrm that it
runs smoothly. If any adjustments are needed,
these must be done with the machine turned off
and unplugged for safety.
If you have any questions regarding assembly
before operating the sander, contact RIKON
Tech Support at 877-884-5167 for assistance.

DISC SANDING
1. Depending on what type of sanding that you
will be doing, set the Sanding Disc Table to the
proper angle from 45° to 90°.
2. Once the table has been set for the correct
sanding angle, and all fasteners are secure, the
machine can be plugged in for operation.
3. Use the Miter Gauge (#110) for added control
of the workpiece during sanding. The miter gauge
can also be set to various degree angles for main-
taining accurate angles when sanding small or
multiple parts.
4. Do not force the workpiece into the sanding
disc. Sand using light pressue, letting the sanding
abrasives time to do their work!
5. Move your workpiece slightly left and right on
the disc, keeping to the left-of-center, downward
side. This will help prevent resin or debris from
building up on one area of the disc, and also helps
to prevent burning of the sanded surface from
excessive abrasive-action heat build-up.
FIG. 16
FIG. 17
FIG. 18
OPERATION
When sanding, always position
your work on the downward, rotating side (left
side) of the sanding disc. FIG. 16. The sanding
action will then force the wood down, safely
towards the table, where it can be controlled.
Sanding on the right, upward rotating side of the
disc is dangerous, as your work cannot be con-
trolled and ‘kick-back’ may occur - the wood being
forced up and out of your hands.
Always ensure the sander is
unplugged prior to attempting any assembly,
installation or changing of parts and accessories.
NOTE: It is strongly recommended that users
employ a dust-collection system when using this
belt & disc sander. Use of a dust mask or respirator
is still recommended, even when a dust-collection
system is in use.

BELT SANDING
1. Depending on what type of sanding that you
will be doing, set the Sanding Belt Table to the
proper angle from 45° to 90° with a protractor, or
other angle measuring tool or pre-cut sample.
2. Once the table has been set for the correct
sanding angle, and all fasteners are secure, the
machine can be plugged in for operation.
3. Use the Miter Gauge (#110) for added control
of the workpiece during sanding. The miter gauge
can also be set to various degree angles for main-
taining accurate angles when sanding small or
multiple parts.
4. Do not force the workpiece into the sanding
belt. Sand using light pressue, letting the sanding
abrasives time to do their work!
5. Move your workpiece slightly left and right on
the belt. This will help prevent resin or debris from
building up on one area of the belt, and also helps
to prevent burning of the sanded surface from
excessive abrasive-action heat build-up.
6. The Platen (#30) supports the back of the
sanding belt and offers a at surface to sand or
sharpen against. It should be positioned so it is
almost touching the back of the sanding belt.
7. To adjust the platen, loosen the hex Screw
(#27) at the rear of the platen. FIG. 20.
8. The platen can also be removed for contour
sanding or polishing.
FIG. 20
SANDING BELT TRACKING
1. Belt tracking on the center of the drive wheels
is pre-set at the factory. If an adjustment need to
be made, the sander must be turned on.
2. Slowly turn the Belt Tracking Knob (#5) to
correct the tracking of the belt - left or right as
needed - so that the belt nally rides on the center
of the top drive wheel (#23). FIG. 21.

ADJUSTMENTS
V-BELT TENSION ADJUSTMENTS
Ensure sander is disconnected from the power
supply prior to commencing work.
Should the rotation of the sanding belt or disc
slow down or stall, the cause may be that the
V-belt is slipping on the two pulleys. This may be
because the motor or frame have become loose
from the base, or that the V-belt has stretched
out due to the machine being used. In either
case, re-adjustment of the V-belt is needed.
1. To gain access to the V-belt, remove the V-
belt rear metal cover (#108) and V-Belt & Disc
Guard (#106).

WIRING DIAGRAM
MAINTENANCE
Turn the power switch “OFF” and disconnect the plug from the outlet prior to
adjusting or maintaining the sander. DO NOT attempt to repair or maintain the electrical components
of the motor. Take the sander to a qualied service technician for this type of maintenance.
MAINTENANCE REQUIRED FREQUENCY
1. Check the power cord for any damage. Before each use.
2. Check sanding belts and discs for damage or wear. Before each use.
3. Check all guards and hardware to make sure they are secure. Before each use.
4. Check all moving parts for alignment and binding issues. Before each use.
4. Dress/Clean sanding surfaces for best abrasive action. As needed
5. Replace sanding belts or discs when worn or damaged. As needed.
6. Clean and vacuum dust from the motor housing and other sander parts. As needed.
7. Keep iron tables free of rust. Apply coat of paste wax or silicon spray. As needed.
NOTE: Lubrication of the bearings is not necessary, as they are sealed and pre-lubricated for life.
Just replace a bearing if failure occurs. Do not use compressed air near bearings. Simply wipe the
exposed bearing surfaces with a dry cloth to clean them.
Service beyond recommended maintenance on these tools should only be performed by an
authorized, qualied technician.

EXTENSION CORDS
Keep the extension cord clear of the working area. Position the cord so that it will not get
caught on lumber, tools or other obstructions while you
are working with a power tool. Check extension cords
before each use. If damaged replace immediately.
Never use a tool with a damaged cord, since touching
the damaged area could cause electrical shock, resulting
in serious injury.
Use a proper extension cord. Only use cords listed by Under-
writers Laboratories (UL). Other extension cords can cause a
drop in line voltage, resulting in a loss of power and over-
heating of tool. When operating a power tool outdoors, use an
outdoor extension cord marked “W-A” or “W”. These cords are
rated for outdoor use and reduce the risk of electric shock.
17
In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current
to reduce the risk of electric shock. This tool is equipped with an electric cord having an equipment-grounding
conductor and a grounding plug. The plug must be plugged into a matching outlet that is properly installed and
grounded in accordance with all local codes and ordinances. Do not modify the plug provided. If it will not  t the
outlet, have the proper outlet installed by a quali ed electrician.
Improper connection of the equipment-grounding conductor can result in a risk of electric shock. The conductor,
with insulation having an outer surface that is green with or without yellow stripes, is the equipment-grounding
conductor. If repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding
conductor to a live terminal. Check with a quali ed electrician or service personnel if the grounding instructions are
not completely understood, or if in doubt as to whether the tool is properly grounded.
Use only three wire extension cords that have three-prong grounding plugs and three-pole receptacles that accept
the tool’s plug.* Repair or replace a damaged or worn cord immediately.
This tool is intended for use on a circuit that has an outlet that looks the one illustrated in Figure A below. The tool
has a grounding plug that looks like the grounding plug as illustrated in Figure A below. A temporary adapter, which
locks like the adapter as illustrated in Figure B below, may be used to connect this plug to a two-pole receptacle, as
shown in Figure B if a properly grounded outlet is not available.** The temporary adapter should only be used until
a properly grounded outlet can be installed by a quali ed electrician. The green colored rigid ear or tab, extending
from the adapter, must be connected to a permanent ground such as a properly grounded outlet box.
* Canadian electrical codes require extension cords to be certi ed SJT type or better.
** Use of an adapter in Canada is not acceptable.
