INTRODUCTION
Your new CRL/SOMACA Belt Sander was developed and improved through the years until it can now be called the finest piece of equipment available
in its price range. The machine incorporates many fine features such as a direct drive, 1 H.P. motor, a gas cylinder-tensioned upper pulley, safety shield,
totally sealed ball bearings eliminating weekly lubrication, and a unique, rust-proof, thick-walled HDPE (High Density Polyethylene) water tank.
Like any good machine, it will give best results if it is properly cared for. It is not necessary to pamper this equipment, but reasonable maintenance will
increase the machine’s life.
We put sealed bearings in our machines because we found that most shops do not take the time to grease the bearings on a routine basis. However,
even sealed bearings do sometimes go bad, and should be inspected on a weekly basis for noise or rough spots. Scrubbing the machine occasionally
will prevent glass and sludge build-up, and any areas where rust is starting to show should be scraped, primed, and repainted to get the maximum life out
of the machine. The AU2300 machine has a 50 Hz, 220V motor with Australian cord and plug but no roller platen or guide wheels. The AU23 has
the roller platen and guide wheels and a 50 Hz, 220V motor with Australian cord and plug.
The instructions on the following pages will guide you through the initial setup, maintenance, and replacement of parts on your machine. Should you
run into any problem or procedure you do not understand, please feel free to call our toll free number [phone], and we will be glad to help you.
Parts and expert advice can also be obtained directly from CRL Glass Machinery at [phone]. International: [phone].

UNCRATING THE MACHINE
Remove the shipping cover and inspect for any damage. If you find any part of your machine has freight damage, save all shipping material and
call the delivering carrier immediately. Tell them you want to file a damage claim and have them send out an inspector. If everything is okay, completely
remove the shipping crate, including the wooden base.
SETTING U THE BELT SANDER
1. Position the sander in your desired location. For best results, the sander should be level and secured to the floor with anchors, fastened through the
holes provided in the sander base.
2. With the belt sander switch in the OFF position, plug the sander into a grounded outlet of the correct voltage. Electrical Specifications for each model
are located on the Serial Number Plate near the belt tensioner and on the top of this page. NOTE: A ground plug is provided for your safety.
LEASE DO NOT ALTER IT IN ANY WAY. Now turn the switch on to see if the motor will run. If it does, go to the next step. If it does not run, check all
electrical connections and try again. If you still have a problem, please call us before going any further.
3. Unplug the sander before going any further. Now you can connect the sander to your city water supply, using copper tubing and a 1/4" NPT
(National Pipe Thread) male connection to the 1/4" NPT female connection in the electric water valve (Photo 1 on Page 4). Note the “flow direction”
marked on the valve with an arrow. Turn the water on and check for leaks. Position a bucket or pan under the drain pipe on the machine, or connect
a hose for discharging into a flume or other device to allow sediment to settle and water to drain off. NOTE: If drained into a sewer, abrasive sand
grindings may accumulate and plug the drain.
4. Plug the machine in again. Be sure the manual water flow control valve (after the electric water valve) has the handle turned in the direction the water
is flowing; this is the OPEN position. Turn the switch ON and the water will begin to spray. The spray pattern on the sander is not adjustable. If the
spray pattern decreases or changes, remove and clean the spray nozzle. The manual water flow control valve (Photo 1 on Page 4) can be adjusted to
reduce the water flow. Do not use any more water than needed to keep the belt wet. Turn the machine OFF. Unplug the sander and go to the next step.
5. Pull the handle to open the side door. Now install a belt over the top and bottom pulley by pulling down on the black handle on the tensioner
mechanism. Be sure the belt is not wrapped over the water nozzle.
NOTE: When grinding glass, only “wet or dry” belts with silicon carbide grain should be used. They come with two types of splices:
overlapping or butt splices. Butt splices can be run in either direction (such as CRL’s finger splice). Overlapping splices can be run only in
the direction indicated by arrows on the inside of the belt. The most common way to put lapped spliced belts on a belt sander is to put the
belt over the pulleys so you can see the arrow pointing up on the back side of the belt. This will give you the proper rotation.
6. With the sander still unplugged, pull the belt through by hand several cycles to adjust the tracking mechanism. Do this as follows: On the left side of
the machine is a blue ratcheting lever. Loosen the locknut behind the lever. Rotate this lever clockwise to move the belt to the right. Rotate the lever
counterclockwise to move the belt to the left. Adjust the blue ratchet lever until you have adjusted the belt so it will stay in the middle of both pulleys
when pulling the belt by hand. If the blue ratchet lever hits an obstruction, pull the handle out toward you and it will rotate without affecting the tracking.
7. Now plug the machine back in, turn the switch ON, and perform the fine tracking adjustments. The goal is to have the belt track in the middle of both
the upper and lower pulleys. Hold the lever and use a 1/2” wrench to tighten the locknut behind the blue lever. If the contact roller does not match up
with the belt at this time, loosen the Square Head Screws in the Platen Bracket and tap the Roller Platen shaft until it aligns even with the belt, then
tighten the screws.
8. The belt tension is not adjustable and is controlled by the tensioner spring. No adjustment is needed. The spring is available as a replacement part.

NOTE: After a year or two of continued machine use, the pulleys will wear and need to be replaced or have a new crown
machined in them. This is usually evident when you cannot get the belt to track and pulley adjustment will not correct the
tracking. To check this, lay a straight edge across the pulley. A new pulley will have a noticeable hump or crown in the middle
of it. A worn-out pulley will be flat or even have a valley in its center. If the pulley is worn, a one degree crown should be
remachined into the surface or the pulley should be replaced with a new one.
recautions:
1. Do not allow hands to come in contact with the belt while it is moving.
2. Be sure safety shield is properly positioned.
3. Do not overload your shop electrical circuits. Be sure wiring is adequate.
4. Be sure your service plug has grounding provisions to be sure the belt sander is grounded at all times.
GENERAL GUIDELINES
USING THE BELT SANDER
The application of the glass and the choice of belt grits are largely a matter of the individual operator’s preference, but the following procedures are
submitted as a guide for general work.
To obtain a round or pencil edge, use a coarse grit belt and lightly bevel the sharp edges left from cutting by running or swiping glass quickly across the
belt. This helps to reduce chipping the glass during succeeding grinding. Draw the glass slowly across the unsupported area of the belt above the platen,
and at the same time tilt the glass up and down until the desired contour is obtained. Finish the edge on a smoothing belt and then polish if desired.
For a flat, seamed edge, use a belt of medium grit and lightly bevel the edges as above. Next, grind the entire edge flat by applying the glass squarely
to the platen. Change to a finishing or smoothing grit and go over the flat edge again, then seam both sides of the glass by tilting it about 45° and running
it across the belt on the platen.
Rough grinding can be done by using abrasive belts in grit sizes 40, 60, 80, and 120. Belts of 150, 180, 220 and 280 grits are for smoothing; grits 320
and 400 for satin finishing; 600 grit and cork belts are for extra high polishing.
LUBRICATION
The only bearings on the sander that may require lubrication are the motor bearings. Check to see if there are grease fittings for applying lubrication.
Time interval: Every six months. NOTE: Apply grease sparingly as overly greased bearings
can create seal failure and eventually cause bearing failure.
Type of grease: CRL Cat.No.WL14 No.2 lithium base grease.
Use CRL Cat.No.1200 Metal Lube weekly on the front rest roller axles.
HOW TO REMOVE AND RE LACE THE ELECTRIC WATER VALVE
1. IM ORTANAT!!! Unplug the machine power supply.
2. Turn off water supply to the machine and disconnect the water supply line from the valve (see Photo 1
on Page 4).
3. Disconnect the water line from the valve to the nozzle by pushing in on the green quick-connect collar and
pulling out on the plastic water line.
4. Open connection box on the motor and disconnect the two gray wires from the wire bundles. See photo.
5. Rotate the conduit nipple under the solenoid counterclockwise (as viewed from under the solenoid). This will
allow the valve to be removed.
6. Unscrew the complete valve assembly from the connection box. Remove the shut-off valve and quick-connect
fitting from the old valve and, using thread sealer, install it into the “OUT” side of the new valve (the “OUT” side
is indicated by the small arrow on the side of the valve, see Photo 2 on Page 4).
7. Apply a thin coat of silicone sealant to the base of the solenoid and feed the two gray wires from the new valve
into the connection box and screw the valve onto the fitting. Tighten the conduit nipple by turning it clockwise against the valve. DO NOT OVER-
TIGHTEN. IMPORTANT: Be sure that the valve is situated as shown in Photo 1 on Page 4, with the arrow on the brass fitting pointing left. The
quick-connect fitting should be pointing left.
8. Connect the nozzle water tube by pushing it into the quick-connect fitting.
9. Inside the box, connect the gray wires; one to each bundle. It does not matter which gray wire is attached to which bundle. Be sure to wrap the
wire connections with electrical tape. (note: the Black wire is EXTRA and only used for 220 Volt applications)
10. Replace the cover to the motor connection box and reconnect the water supply. Plug in the machine power supply.
11. Turn on water supply. Turn on the machine and check for leaks. Check that there is water spraying from the nozzle.
12. Make sure the nozzle is NOT spraying when the power is shut off, and make a final check for leaks on all connections.

Remove and Install Motor
NOTE: This is a straight-forward job that requires a basic knowledge of electrical wiring. If you do not feel confident in your ability to connect
wires, have a qualified electrician change the motor for you.
1. Unplug the machine, turn off the water supply, and remove the sanding belt.
2. Before removing the bottom pulley, measure the distance from the back side of the pulley to the side of the tank (Photo 4, Page 4). Record this
measurement so you can replace the pulley at this same distance. This will help keep the belt alignment to original specs.
3. Loosen two set screws on the pulley with a long 5/32” Hex/Allen wrench. These can be accessed through the two holes in the pulley. Remove the pulley.
4. Disconnect the wiring from the motor by removing two screws on the connection box cover on the motor. Remove the water solenoid (page 2).
5. On 120 volt motors, pull the Brown wire from motor lug No. 1 (per the drawing on the motor) and the Yellow and Blue wires from motor lug No. 2.
6. Disconnect the Green ground wire from the ground screw. (See wiring diagrams on page 8)
7. Those are the three power wires plus a green ground wire coming from the power line in. Mark which motor connection each one goes to for rewiring.
8. With the power wires disconnected from the motor, the power cable can be disconnected from the motor.
9. The four bolts holding the motor to the machine can now be loosened.
10. The motor itself weighs about 40 lbs (18 kg). Use a small jack or have a helper hold the motor up while the bolts are loosened. Slowly pull the motor
from the machine.
11. Align the new motor with the bolts. Capacitor should be facing up. Tighten the bolts from inside the tank. Mount the solenoid and water lines as
indicated on page 2.
12. Reconnect the power cable and connect the four wires to the motor lugs as removed and replace the metal cover. Plug in the power cord and check
for motor operation. The motor should turn counterclockwise as viewed from the shaft end in the tank. Reverse wires #5 and #8 to correct rotation.
13. After motor operation is confirmed. UNPLUG the power cord, apply a small amount of light grease to the motor shaft to prevent rust, and replace the
lower pulley and the sanding belt. Remember to refer to the “pulley to tank” measurement that was made in step #2. The water supply can now be
turned back on.
14. Turn the belt through two complete rotations by hand and check the alignment. Adjust as needed to make the belt track straight on all three wheels.
Remove and Replace Sanding Belt, Upper and Lower ulleys, and Roller laten
Always UN LUG the machine before doing ANY work on it. The sanding belt should be removed before attempting any work on ulleys or the
Roller laten.
Sanding Belt
The sanding belts are easy to replace. With the belt door on the right side of the machine open, firmly pull down on the black tensioner handle.
This will allow the belt to be removed from the top pulley and then from the lower pulley. Belt installation is just as simple. Hold the belt with one hand,
gripping the middle, and loop the bottom of the belt around the lower pulley. Make sure that the belt is not between the water spray nozzle and the tank
side. Slide one side of the belt over the platen roller and pull down on the tensioner handle. This will allow you to put the top of the belt over the top pulley.
Check that the nozzle is not hooked on the belt and pull the belt through two complete rotations to check the tracking.
Lower ulley
Before removing the lower pulley, measure and record the distance from the back edge of the pulley (closest to the motor) to the side of the tank, as
shown in Photo 4 on Page 4. The Lower Pulley is removed by first removing the sanding belt and then removing two set screws, accessed through two
holes in the pulley, with a 5/32” Hex/Allen wrench (Photo 5, Page 4).
Upper ulley
The Upper Pulley is mounted on a shaft with two sealed bearings and lock rings. It is recommended that the pulley, shaft, and bearings be replaced as
a unit. Loosen the two square head screws on the pulley shaft support on the tensioner (Photo 3, Page 4). Slide the shaft out toward the pulley.
Lightly coat the new shaft with grease and insert the new shaft and pulley into the support with the end of the shaft protruding about 1/16" past the end of
the support. (Photo 3, Page 4) Tighten the square head screws. On older machines you may need a wood or plastic hammer to tap the shaft out. Do not
hit the pulley itself with anything.
Roller laten
The Roller Platen is made as an assembly with the roller, two sealed bearings, and the shaft. It is best to measure and record the distance from the
inside edge of the roller to the bracket (Photo 6, Page 4) so the new Roller Platen can be placed close to the same position.
To replace the Roller Platen, remove the sanding belt, then loosen two square head set screws on the Roller Platen bracket (Photo 6, Page 4), and
remove the assembly. Fit the new assembly at the same distance from the bracket as the old Platen, then tighten the two set screws. Replace the belt,
turn on the machine and check that the platen and belt are running true.

ROLLER LATEN, U ER ULLEY, SHAFT AND BEARINGS
For ease of maintenance and durability, the Roller Platen and Top Pulley Assemblies are supplied as one-piece assemblies. Replacing the bearings or
shaft alone requires a press and an experienced operator. Because the roller platen, top crowned pulley itself, and the bearings are some of the few parts
of the 2300RP that may need replacement, they are sold as unit assemblies. These assemblies can be replaced quickly with simple hand tools by following
the instructions on Page 3 of this manual. Assistance with any maintenance operation on the 2300RP is avaliable by calling the CRL/Sommer & Maca

CRL Platens below can only be used on the 2300 machine.The A100 adapter must be fitted. These accessories DO NOT
fit the 2300R , which has a Roller latten attached. The BP2001 Bar Platen will produce a slightly rounded edge. The
FP2002 Flat Platen will work best when flat edges are desired. The 3MP2200 3M Platen provides a hard metal plate with a soft
rubber pad behind it for working both types of edges. The 330010, Roller Platen (page 9) can be used on the 2300 by using the
PA100 below. Minimum order is one each.
