Operation

Figure 22 shows the control panel functions.
The Emergency Stop shuts down all functions
on the band saw. The machine will not start if
the emergency stop is still engaged. To start the
machine, twist the emergency stop button until it
pops back out.
IMPORTANT: When cutting magnesium, never
use soluble oils or emulsions (oil-water mix) as
water will greatly intensify any accidental
magnesium chip fire. See your industrial coolant
supplier for specific coolant recommendations
when cutting magnesium.
General Operating Procedure:
1. Give machine an overall inspection. Verify
that all guards, covers, etc. are in place and
in working order, the blade is tensioned
properly and the tooth direction matches the
arrow on the bow. Check that the blade
guides are set correctly, and also the wire
brush.
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 23 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. Do not reach
into the cutting
operations.
3. Rotate the speed dial to the desired setting.
Do not rotate the speed dial during a
cutting operation.
4. Set a suitable downfeed rate for that
operation on the cylinder dial.
5. Push the start button to start the blade
circulating.
6. Turn on the coolant flow.
