SELECT THE RIGHT BLADE

It is essential to reduce operating costs to a minimum. By using the correct Power saw blade, the required performance will be achieved either by increasing the number of sections cut per blade or by reducing the cutting time per section.

GUIDE TO THE CORRECT NUMBER OF TEETH AND MACHINE SPEED

This is dependent on the material and thickness to be cut.

For thinner work pieces, select the faster blade speed and for thicker work pieces select the slower blade speed.

The harder or tougher the material, the slower the blade speed.

*If machine has interchangeable speeds, use the slow speed for the easier to machine steels, and for the more difficult to machine steel, use the faster speed.

TIPS FOR CORRECT PREPARATION

1. Keep your machine in good condition and, in particular, the lifting mechanism and if applicable the slides of the bow.

2. Use an Eclipse Power Saw Blade of the right type and size. With the correct number of teeth,fitted with the teeth pointing in the direction of the cutting stroke as specified by machine manufacturer.

3. Tension in accordance with the machine manufacturer's is instructions.

4. Secure the work firmly with small sections grouped together to use the full stroke. Make sure that cutting will start with at least three consecutive teeth in contact.

5. Use a coolant or cutting compound (except on cast iron or high nickel chrome steel), and run the machine at the correct speed . See table for recommended speed.

6. After starting the machine, lower the frame carefully and relieve the weight (or reduce the feed) for a few strokes. After cutting the first two or three sections, check that the tension is still conttect.
