SAFETY

This is the safety alert symbol. When you see this symbol on your press be alert to the potential for personal injury.
Employer is responsible to perform a hazard/PPE assessment before work activity.
Follow recommended precautions and safe operating practices.

• Untrained operators have a higher risk of being hurt or killed. Only allow trained/supervised people to use this machine. When machine is not being used, disconnect power, remove switch keys, or lock-out machine to prevent unauthorized use.
• Only use machine in clean, dry, and safe environment. Make sure there are no flammable or combustible materials near the machine. Sparks cause from metal can cause ignition.
• Always disconnect machine from power supply BEFORE making adjustments, changing tooling, cleaning or servicing machine.
• Only allow qualified service personnel to do electrical installation or repair work, and always disconnect power before accessing or exposing electrical equipment.
• Always wear approved safety glasses or a face shield when operating or observing machinery.
• Do not wear clothing or jewelry that can be caught in moving parts. Always tie back or cover long hair. Wear non-slip footwear to reduce risk of slipping and losing control or accidentally contacting cutting tool or moving parts.
• Dust created by machinery operations may cause cancer, birth defects, eye damage, raspatory issues or long-term respiratory damage. Be aware of dust hazards associated with each workpiece material.
• Always wear hearing protection when operating or observing loud machinery.
• Do not set or leave tools on machine while machine is in use.
• Make sure machine is on stable ground, movement during operation increases risk of injury or machine damage.
• Turn machine off when not in use, never leave machine running unattended.
• Inspect machine before each use for damaged or loose parts.
• The gap between moving grinding belt and table/support creates a pinch point for fingers or workpieces; the larger this gap is, the greater the risk of fingers or workpieces getting caught in it. Minimize the risk of pinch and crush injuries by adjusting table/support to no more than 1/16″ away from belt.
• Always use a jig when working on small workpieces, always keep fingers at least 2” away from work area.
• Do not wear gloves while grinding.
• Worn or damaged grinding belts can fly apart and throw debris, or aggressively grab workpiece, causing injury from operator loss of workpiece control. Always inspect belt before operation and replace if worn or damaged.
• Only grind against direction of sandpaper travel, ensure workpiece is properly supported, and avoid introducing sharp edges into moving belt on the leading side of the workpiece.

SET UP

When unpacking machine inspect all parts for shipping damage.

PLACEMENT
Below is the minimum area needed for machine. Plan enough space forworkpieces and any material stands that may be used in the future. ANCHORING
Make sure machine is complaint with local laws and legislation for anchoring machinery.

• Anchoring machine to the floor prevents tipping or shifting and reduces vibration that may occur during operation, resulting in a machine that runs quieter and feels more solid.
• If the machine will be installed in a commercial or workplace setting, or if it is permanently connected (hardwired) to the power supply, local codes may require that it be anchored to the floor.
• If not required by any local codes, fastening the machine to the floor is an optional step. If you choose not, we recommend placing it on machine mounts, as these provide an easy method for leveling and they have vibration-absorbing pads.

ELECTRICAL
Electrical wiring must be done by an electrician or qualified service personnel in accordance with all applicable codes and standards.
Machine is prewired to operate on the following power supply requirements

Full-Load Current Rating at 220V: 3.9 Amps
If the machine is overloaded for a sufficient length of time, damage, overheating, or fire may result— especially if connected to an undersized circuit. To reduce the risk of these hazards, avoid overloading the machine during operation and make sure it is connected to a power supply circuit that meets the specified circuit requirements.
Circuit requirements in this manual apply to a dedicated circuit—where only one machine will be running on the circuit at a time. If machine will be connected to a shared circuit where multiple machines may be running at the same time, consult electrician or qualified service personnel to ensure circuit is properly sized for safe operation.
GROUNDING
Machine must be grounded!
No adapter should be used with machine plug!
The wire with green insulation (with or without yellow stripes) is the equipment-grounding wire. If repair or replacement of the power cord or plug is necessary, do not connect the equipment- grounding wire to a live (current carrying) terminal.
EXTENSION CORD
The use of an extension cord with this machine is not recommended! Only use an extension cord if necessary and only on a temporary basis.
If extension cord must be used temporarily make sure cord is in good condition, matches plug configuration, and meets the following requirements:

INSTALLING/CHANGING BELT

1. Make sure machine is not connected to power source.
2. Use key to unlock and open belt access door.
3. Turn belt tension lock knob counterclockwise to loosen lock ollar and release belt tension lever.
4. Move belt lever down and toward drive motor and release belt tension.
5. Remove old belt (in installed) and replace with new belt. Be sure the new belts arrow matches the direction of rotation of the machine.
6. Move belt tension lever up and away from drive wheel to raise motor and tension the belt.
7. Check and adjust belt tracking after installing new belt. See “FISRT RUN” section of this manual.

CHECKING/ADJUSTING BELT TRACKING

1. Make sure machine is not connected to power source.

2. Use key to unlock and open belt access door.

3. Standing in front of machine rotate either wheel by hand so the belt moves in the direction of rotation of the machine (counterclockwise on wheels and towards work rest)
   a. If belt moves left on wheels (towards motor): Rotate belt adjustment knob counterclockwise 1/4 turn.
   b. If belt moves right on wheels (away from motor): Rotate belt adjustment knob clockwise 1/4 turn.

4. Repeat step 3 until belt tracks in center of wheels, once done close access door.

5. Connect machine to power and verify belt is tracking correctly, fine-tune tracking as necessary while machine is running.

6. Once tracking is fine-tuned turn the machine OFF and loosen the work rest lock knob to adjust to work rest so that there is no more that a 1/16” between the rest and the belt. Tighten down lock knob to secure.

FIRST TIME OPERATION

In the first run, there are 3 things to look for:

• Belt tracks properly and will not come off wheel.
• Motor runs correctly.
• E-Stop disables machine properly.

1. After connecting machine to power, jog the machine on but hitting the ON button followed by immediately hitting the OFF button.

2. While the belt moves look to see if it is tracking correctly. Belt should remain centered on wheel as it rotates.
   a. If belt tracks too far right or left belt edges will get destroyed.
   b. Adjust tracking using the knob to the left of the work area.
   c. Belt should rotate in same direction as arrow on machine. If this is incorrect refer to “CORRECTING PHASE POLARITY” section of this manual.

3. Ensure motor runs smoothly then activate the E-Stop to ensure E-Stop is working properly.
   a. When E-Stop is activated the cover will shut, if the cover does not close when the E-Stop is activated E-Stop is not working properly. Disconnect from power and troubleshoot.

CORRECTING PHASE POLARITY

If you discover during the test run that the machine will not operate, or that the motor runs backwards, the plug may be wired “out of phase,” meaning the polarity is incorrectly wired.

1. Disconnect machine from power source.
2. Remove cross head screws to open ON/OFF switch cover.
3. Swap any 2 leads of the 3 incoming power wires (L1, L2 L3)
4. Close ON/OFF switch cover and replace screws removed in step 2.
5. Reconnect machine to power.
6. Test machine

DUST COLLECTION
To fit a dust collection system to the machine:
Fit 3” ducting over the dust port and secure with clamp. Make sure connection is secure.

OPERATION

1. Turn machine on.
2. Position work piece on center of work rest. Always use 2 hands and the work rest to support your work.
3. Using both hands slowly feed it into contact wheel with light consistent pressure. DO NOT force the work against the belt/wheel.
   a. There is workpiece clearance on both sides of the contact wheel to grind the sides of your work piece.

CHOOSING A BELT
Machine uses 3” x 79” belt.
