Operation

The PB-85 and PB-150 Band Saws have been designed for dry cutting of metals only. Also, do not cut magnesium as this may present a fire hazard.

Support long workpieces with roller stands.

The start/stop switch contains a safety feature. To prevent the band saw from being turned on, pull out the section of the switch, as shown in Figure 15, and store it in a safe place. To operate the band saw, re-insert the switch section.

The band saw has an internal thermal overload to protect the motor, and will activate in case of numerous successive cuts or constant overfeeding. If the machine suddenly shuts off, release the button on the hand grip. Wait several minutes for the thermal overload to re- set itself, then press the hand grip button again.

Remove cut or jammed workpieces only when the motor has been turned off and blade is at a complete standstill.

General Operating Procedure:

1.Verify that all guards, covers, etc. are in place and in working order, and the blade is tensioned properly.

2.Place workpiece in vise and tighten vise. The workpiece should be fitted directly between the jaws without adding other objects.

When the workpiece to be cut is a profiled section, flat piece or special shape, refer to the examples shown in Figure 16 for proper clamping positions. The top row shows acceptable clamping positions, the bottom row shows unacceptable positions.

If the thickness of the profiled section is very thin, a piece which duplicates the profile should be fitted inside the workpiece itself, to prevent the workpiece being crushed between the jaws.

Never hold a workpiece by hand when cutting it. The workpiece should be firmly secured in the vise. Never reach into the cutting area during cutting operations.

3.Set the blade guide assembly as close to the workpiece as possible to prevent excess exposure of the blade during the cut.

4.Flip up the switch to START position.
