3. Persediaan dan Pemasangan
3.1 Membongkar dan Pemeriksaan
Carefully unpack all components. Inspect the machine for any damage that may have occurred during transit. Report any damage to your supplier immediately. Ensure all parts listed in the packing list are present.
3.2 Base Assembly and Placement
The band saw is delivered with a base designed to facilitate the installation of a cooling system (if applicable) and provides stability. Assemble the base according to the included assembly diagram. Position the machine on a firm, level surface capable of supporting its weight (86 kg gross). Ensure adequate clearance around the machine for safe operation and material handling. The integrated wheels allow for easy repositioning within the workshop.
3.3 Sambungan Elektrik
Connect the machine to a grounded 230 V, 50 Hz power supply. Ensure the electrical circuit is protected by an appropriate fuse or circuit breaker. Do not use extension cords unless absolutely necessary, and ensure they are rated for the machine's power requirements (550 W).
3.4 Pemasangan Bilah
The machine is supplied with one blade. To install or replace the blade (dimensions: 1638 x 0.6 x 13 mm):
- Pastikan mesin diputuskan daripada bekalan kuasa.
- Open the blade guard covers.
- Carefully position the blade around the wheels, ensuring the teeth are pointing in the correct cutting direction.
- Adjust the blade tension until it is firm but not overly tight. Refer to the machine's tensioning mechanism for specific instructions.
- Adjust the ball-bearing blade guides to ensure proper blade alignment and support.
- Close the blade guard covers securely.
3.5 Vise Setup
The quick-release vise is used to secure the workpiece. Adjust the vise jaws to accommodate the material size. The integrated cutting stop helps ensure repeatable cut lengths.
4. Arahan Operasi
4.1 Menghidupkan/Mematikan
To turn the machine on, press the green START button. To turn it off, press the red STOP button. The machine also features an automatic stop function that will halt operation once a cut is completed.
4.2 Adjusting Cutting Angle
The saw bow can be rotated from -45° to 60° to perform miter cuts. Loosen the locking mechanism, adjust the bow to the desired angle using the angle scale, and then securely tighten the locking mechanism.
4.3 Adjusting Blade Speed
The machine offers three blade speeds: 23, 34, or 54 meters per minute (M/min). Select the appropriate speed based on the material being cut. Softer metals generally require higher speeds, while harder metals require lower speeds. Refer to the machine's speed selection mechanism for adjustment.
4.4 Adjusting Descent Speed
The descent speed of the saw arm is continuously adjustable via a hydraulic cylinder. Adjust the control knob to achieve the desired feed rate for optimal cutting performance and blade life. A slower descent speed is generally recommended for harder materials or larger workpieces.
4.5 Cutting Capacities
The maximum cutting capacities are as follows:
- Round Solid Material:
- 125 mm at 90°
- 95 mm at 45°
- 50 mm at 60°
- Pro Rectangularfile Bahan:
- 100 x 150 mm at 90°
- 95 x 76 mm at 45°
- 50 x 56 mm at 60°
