Persediaan dan Perhimpunan
The Delta 28-400 band saw requires assembly before use. It is recommended to have assistance during assembly due to the weight and size of the components.
1. Membongkar dan Pemeriksaan
Carefully remove all components from the packaging. Inspect for any shipping damage. Ensure all parts listed in the packing list are present. The saw, stand, 4-inch dust port, and a 93-1/2 inch blade are included.
Figure 1: The Delta 28-400 Band Saw fully assembled on its stand.
2. Perhimpunan Berdiri
Assemble the heavy-duty steel stand according to the instructions provided in the separate stand manual. Ensure all bolts are securely tightened. The stand provides a stable base for the band saw.
3. Mounting the Saw to the Stand
With assistance, carefully lift the band saw body and place it onto the assembled stand. Secure it using the provided hardware. Ensure the saw is level and stable on the stand.
4. Blade Installation and Tensioning
- Buka penutup roda atas dan bawah.
- Loosen the blade tension knob to allow for blade installation.
- Carefully place the blade around the upper and lower rubber-coated wheels, ensuring the teeth are pointing downwards towards the table.
- Adjust the blade tracking so the blade runs centrally on the wheels.
- Apply appropriate blade tension using the tensioning system. While there isn't a specific tension indicator, ensure the blade is taut enough to prevent twisting during operation.

5. Blade Guide Adjustment
Proper blade guide adjustment is crucial for accurate cuts and blade longevity. The saw features upper and lower blade guides.
- Adjust the upper blade guide assembly so it is approximately 1/8 inch above the workpiece.
- Ensure the side guides are set close to the blade, but not touching, allowing the blade to run freely.
- Adjust the thrust bearing (rear guide bearing) so it is just behind the blade, providing support during cutting without constant contact.

6. Pelarasan Jadual
The precision ground cast iron table can tilt from 3° left to 45° right, with a positive stop at 90° for straight cuts.
- Longgarkan tombol pengunci meja.
- Tilt the table to the desired angle. Use a protractor or angle gauge for precise settings if not using the 90° stop.
- Tighten the table locking knob securely before operation.

7. Sambungan Kuasa dan Voltantage Pemilihan
The 1 HP TEFC motor can operate on either 115V or 230V. Ensure the motor is wired correctly for your power supply. Consult a qualified electrician if you are unsure about wiring for 230V. Always ensure the power switch is in the OFF position before connecting to power.
8. Pengumpulan Habuk
Connect a dust collection system to the 4-inch dust port to maintain a clean work environment and improve visibility. The saw's design includes effective dust collection features.
Arahan Operasi
Before operating, ensure all safety checks are performed, including blade tension, tracking, guide settings, and table angle.
1. Menghidupkan/Mematikan
To start the saw, press the green "ON" button. To stop, press the red "OFF" button. Always allow the blade to reach full speed before beginning a cut.
2. Pemilihan Kelajuan
The band saw offers two speeds: 1,620 FPM (Feet Per Minute) and 3,340 FPM. The lower speed is suitable for cutting non-ferrous metals, while the higher speed is for woodworking. Change speeds by adjusting the belt on the two-speed pulley system. Refer to the motor compartment for detailed instructions on changing belt positions.
3. Membuat Potongan
- Ensure the workpiece is free of foreign objects (nails, screws).
- Adjust the upper blade guide to be approximately 1/8 inch above the workpiece.
- Pegang bahan kerja dengan kuat pada meja.
- Masukkan benda kerja secara perlahan-lahan dan stabil ke dalam bilah. Jangan paksa potongan.
- Use a push stick for small pieces or when hands are close to the blade.
- For curved cuts, use a narrower blade and feed slowly, allowing the blade to follow the curve without twisting.
Penyelenggaraan
Regular maintenance ensures the longevity and safe operation of your Delta 28-400 band saw. Always disconnect power before performing any maintenance.
1. Pembersihan
- After each use, clear sawdust and debris from the table, blade guides, and inside the wheel covers.
- Use a brush or vacuum cleaner. Do not use compressed air as it can force dust into bearings.
- Keep the motor vents clear of dust to prevent overheating.
2. Penggantian Bilah
Replace dull or damaged blades promptly. Follow the blade installation steps in the Setup section. Ensure the new blade is the correct length (93-1/2 inches) and width for your application.
3. Wheel and Bearing Inspection
- Periodically inspect the rubber tires on the upper and lower wheels for wear or damage. Replace if necessary.
- Check the blade guide bearings for smooth operation. Replace any bearings that are seized or excessively worn.
4. Table Surface Care
Keep the cast iron table clean and apply a rust preventative or paste wax periodically to maintain its smooth surface and prevent corrosion.
