General Machinery Cautions
- Misuse of this machine can cause serious injury.
- For safety, machine must be set up, used and serviced properly.
- Read, understand and follow instructions in the operator’s and parts manual which was shipped with your machine. When setting up machine:
- Always avoid using machine in damp or poorly lighted work areas.
- Always be sure machine is securely anchored to the floor.
- Always keep machine guards in place.
- Always put start switch in “OFF” position before plugging in machine. When using machine:
You — the stationary power tool user — hold the key to safety. Read and follow these simple rules for best results and full benefits from your machine. Used properly, Wilton’s machinery is among the best in design and safety. However, any machine used improperly can be rendered inefficient and unsafe. It is absolutely mandatory that those who use our products be properly trained in how to use them correctly. They should read and understand the Operators and Parts Manual as well as all labels affixed to the machine. Failure in following all of these warnings can cause serious injuries.
- Never operate with machine guards missing.
- Always wear safety glasses with side shields (See ANSI Z87.1)
- Never wear loose clothing or jewelry.
- Never overreach — you may slip and fall into the machine.
- Never leave machine running while you are away from it.
- Always shut off the machine when not in use. When servicing machine:
- Always unplug machine from electrical power while servicing.
- Always follow instructions in operators and parts manual when changing accessory tools or parts.
- Never modify the machine without consulting Wilton Corporation.
Machinery general safety warnings
1. Always wear protective eye wear when operating machinery. Eye wear shall be impact resistant, protective safety glasses with side shields which comply with ANSI Z87.1 specifications. Use of eye wear which does not comply with ANSI Z87.1 specifi­cations could result in severe injury from breakage of eye protection.
2. Wear proper apparel; no loose clothing or jewelry which can get caught in moving parts. Rubber soled footwear is recommended for best footing.
3. Do not overreach. Failure to maintain proper working position can cause you to fall into the machine or cause your clothing to get caught — pulling you into the machine.
4. Keep guards in place and in proper working order. Do not operate the machine with guards removed.
5. Avoid dangerous working environments. Do not use stationary machine tools in wet or damp loca­tions. Keep work areas clean and well lit.
6. Avoid accidental starts by being sure the start switch is “OFF” before plugging in the machine.
7. Never leave the machine running while unattended.
8. Disconnect electrical power before servicing. Whenever changing accessories or general mainte­nance is done on the machine, electrical power to the machine must be disconnected before work is done.
9. Maintain all machine tools with care. Follow all maintenance instructions for lubricating and the changing of accessories. No attempt shall be made to modify or have makeshift repairs done to the machine. This not only voids the warranty but also renders the machine unsafe.
10. Machinery must be anchored to the floor.
11. Secure work. Use clamps or a vise to hold work, when practical. It is safer than using your hands and it frees both hands to operate the machine.
12. Never brush away chips while the machine is in operation.
13. Keep work area clean. Cluttered areas invite accidents.
14. Remove adjusting keys and wrenches before turning machine on.
15. Use the right tool. Don’t force a tool or attach­ment to do a job it was not designed for.
16. Use only recommended accessories and follow manufacturers instructions pertaining to them.
17. Keep hands in sight and clear of all moving parts and cutting surfaces.
18. All visitors should be kept at a safe distance from the work area. Make workshop completely safe by using padlocks, master switches, or by removing starter keys.
19. Know the tool you are using — its application, limitations, and potential hazards.

General Electrical Cautions
This machine should be grounded in accordance with the National Electrical Code and local codes and ordinances. This work should be done by a qualified electrician. The machine should be grounded to protect the user from electrical shock.
Wire sizes
Caution: for circuits which are far away from the electrical service box, the wire size must be in­creased in order to deliver ample voltage to the motor. To minimize power losses and to prevent motor overheating and burnout, the use of wire sizes for branch circuits or electrical extension cords accord­ing to the following table is recommended:
Conductor length
AWG (American wire gauge) number
240 volt lines 120 volt lines
0-50 feet 50-100 feet Over 100 feet
No. 14 No. 14 No. 12
No. 14 No. 12 No. 8
Safety Requirements for Abrasive Sanding Machines
Abrasive sanding can be hazardous to operators and bystanders. Sanding sparks, chips and dust particles thrown off by the sanding disc can cause serious injury by contact or inhalation. To avoid injuries you must comply with the following safety requirements:
1. Always wear protective eyewear when operating machinery. Eye wear shall be impact resistant, protective safety glasses with side shields which comply with ANSI Z87.1. Use of eye wear which does not comply with ANSI Z87.1 specifications could result in severe injury from breakage of eye protec­tion. See Figure A, below.
2. Wear leather safety gloves, arm guards, leather aprons and safety shoes.
3. A dust collection system is recommended, Operator shall also wear a dust mask at all times. See Figure B, below.
4. Additional precautions may be necessary for sanding materials which are flammable or have other hazardous properties. You should always consult the
6
manufacturer of such materials for instructions on sanding and handling.
5. Do not force or jamb the workpiece into the sanding disc.
6. Before sanding, always allow the motor to come up to operating speed, then check the sanding disc
for wobble, runout, or any unbalanced condition. If the disc is not operating accurately and smoothly, immediately stop the motor and make repairs before attempting any sanding operations.
7. Abrasive discs must be stored in a controlled environment area. Relative humidity should be 35% to 50% and the temperature should be between 60 and 80 degrees Farenheit. Failure to do so could cause premature disc failure.
8. Examine the face of the sanding disc carefully. Excessive sanding which wears down to the backing material can tearing of the disc. Never use a disc which shows backing, nicks or cuts on the surface or edge or damage due to creasing or poor handling.
9. When installing a new disc, be certain the disc is accurately centered on the drive wheel. Failure to do so could cause a serious unbalanced condition.
10. Always present the workpiece to the wheel while resting the workpiece firmly on the table. Failure to do so could result in damage to the workpiece or throwing of the workpiece off the wheel.
11. Safety shoes which comply with ANSI Z41.1 shall be worn. See Figure C.
12. Personal hearing protection such as ear plugs or ear muffs shall be used to protect against the effect of noise exposure. See Figure D.

The sander has both a sanding belt and a sanding disc for use on a variety of work pieces and materi­als.
The platen housing for the belt sander can be posi­tioned vertically or horizontally. When in the vertical position, the drum at the upper end of the platen housing can be used for contouring. A tracking adjustment mechanism for the sanding belt is pro­vided at the upper end of the platen housing.
The platen housing has a lever that is used to apply tension to the sanding belt. The sanding belt is easily replaced by releasing the tension lever, removing a sanding shroud and dust collection duct at the bottom of the platen housing, and slipping the belt from the belt sander drums. Installation is the reverse of the removal steps.

The disc sander consists of an aluminum disc onto which is installed an adhesive-backed sanding and other abrasive discs. The disc is contained within a ducted shroud.
The sanding disc can be replaced by removing the table and a cover over the lower portion of the disc. If desired, the aluminum disc can be removed from its drive shaft to ease replacement of the sanding disc.
The drive motor for the belt and disc sander is attached to the underside of the machine base. An ON/OFF switch is mounted on the machine base on the side opposite the disc sander. Electrical wiring for the motor enters the machine base below the ON/ OFF switch and is routed to the switch and motor inside the machine base.
The belt and disc sander is driven by V-belts con­nected to the drive motor. A pulley on the motor shaft drives a V-belt that drives a dual-groove pulley on an idler shaft. A second V-belt is installed in the second groove of the dual-groove pulley and connects to a pulley on belt sander drive shaft.
Installation and Setup
Mounting
It is recommended that the belt and disc sander be secured to the floor for safe operation. The machine stand has mounting holes in a flange on the inside of stand enclosure. The stand can be secured to the floor using these mounting holes.
Electrical Connection
Refer to the Wiring Data section for wiring informa­tion. Electrical power should be connected by a qualified electrician. Observe local electrical codes when connecting and grounding the machine.
The aluminum sanding disc is driven off the end of the idler shaft. A shaft connected to the second V­belt pulley drives the belt sander drive drum.
The belt and disc sander is mounted on a stand that can be secured to the floor to stabilize the machine. The stand has a door for access to the fasteners for the machine base.

Wiring Data
Single phase electrical hook-up
Note: Local electrical codes in many jurisdictions do not allow the use of plug type connections for single phase power when the machine is used in a commer­cial or industrial establishment.
When connecting your machine to single phase power you may be connecting to either 115 or 230 volts, depending upon the motor type provided. Local codes may, or may not, permit the use of a plug type of connection for your machine. Where a plug connection is permitted, the following installation practices must be followed:
1. The plug used must be a grounding type of plug. On a 115 volt single phase connection, the plug must be a three-prong plug with two flat, parallel blades for the power wires and a single rounded or U-shaped prong for the ground connection. On 230 volt single phase connections, the lug must be a three prong plug with two flat blades in tandem to carry the current, and a third round or U-shaped prong for the ground connection.
2. The service branch to which the plug is connected must be a branch with a separate ground wire so the grounding prong of the plug can be con­nected to ground effectively.
In these cases you must connect your machine to the service branch using a hard-wired junction box connection.
All Wilton sanders are shipped with the power cable terminating without a plug on the assumption the machine will be hard-wired to its service branch.
Circuit protection
Where the service branch is protected with a fuse or circuit breaker which is too high a value to offer protection to the motor supplied, a fuse or circuit breaker box should be used at the point where the machine connection is made and the time delay fuse or circuit breaker should be a value just slightly higher than the maximum load current draw as specified on the motor plate on the motor.
Correcting motor rotation in single phase motors
Wilton provides single phase motors in both 115 volt and 230 volt configuration. Several motor manufac­tures may be used by Wilton for motors of this type.
14
Figure 10: Pictoral diagram for single phase motor, 115 volts w/plug.
Figure 11: Pictoral diagram for 3-phase motor.
These motors may, or may not, rotate in the correct direction -- counter-clockwise -- when connected to your single phase power source. If, after connec­tion, the motor runs in the correct counter-clockwise direction, the power connection is successful.
CAUTION: IF THE MOTOR RUNS CLOCKWISE WHEN CONNECTED TO YOUR SINGLE PHASE POWER SOURCE, YOU MUST DISCONNECT THE POWER SOURCE, OPEN THE JUNCTION BOX AND FIND THE CORRECT WIRING CONNECTIONS FOR THE MOTOR, OR LOCATE THE WIRING CONNECTIONS REQUIRED ON THE MOTOR PLATE ON THE OUTSIDE OF THE MOTOR.
Different manufacturers provide different wiring configurations for correcting the rotation of the motor armature. Therefore, no wiring diagrams for these motors are provided in this manual. Always consult the motor plate and/or the wiring diagram inside the junction box if rotation direction is not correct.
Connecting Power for 3-phase Motors
1. Be certain the power to the branch you are
connecting is off, and locked out, so power cannot be reestablished, accidentally.
2. Connect the ground wires. Thse wires will be
either green, or green with a white trace.
3. Connect the remaining three cable wires to the
three power wires in the service branch.
4. Reestablish power to the branch.
5. Turn the machine on. The motor should be
turning counter-clockwise, the belt sander should be moving downward, and the disc sander should
be turning clockwise. If this is the case, the machine can be considered wired correctly. If the motor is not turning in the correct direction, take the following corrective action:
6. Disconnect power in the branch again and be certain it cannot be accidentally turned on while you correct the wiring.
7. Reverse ANY TWO of the power wires to the machine.
8. Reestablish power in the service branch to the machine.
9. Turn on the machine again. The motor should now be turning in the correct direction.
