Operation
9.1
Automatic shut-off
9.1.1
Cut completion
Limit switches (A, Figure 9-1) control bow
movement. Saw must automatically shut off when
cut is completed. The switches are pre-set by the
manufacturer, but can be adjusted if needed.
Figure 9-1: auto shut-off switch
9.1.2
Blade breakage
If the blade breaks during operation, a sensor near
drive wheel will shut off the saw (Figure 9-2).

9.2
Auxiliary coolant hose
The saw is equipped with auxiliary coolant hose and
spray nozzle. This can be used to direct greater
volume of coolant at workpiece, or for washing off
table area.
9.3
Prior to Operation
1. Check that blade tooth direction matches
diagram on blade guard, and blade guides are
properly set.
2. Check to see that blade is properly seated on
wheels after applying correct tension
(approximately 25,000 lbs.).
3. Select proper speed and feed rate for material
being cut.
4. Material to be cut must be securely held in vise.
5. Check to see that coolant level is adequate and
turn on coolant pump if material to be cut
requires it. Machine should be filled with
approximately 23L (5.2 gal.) of proper coolant
mixture. Follow directions on product maker’s
label and fill coolant tank through chip tray area.
6. Do not start cut on a sharp edge.
7. Keep machine lubricated. See
sect. 10.2.
9.4
General operating procedure
All blade covers and machine
guards must be in place and secured before
turning on band saw.
1. Select proper speed on digital readout for type
of material to be cut.
2. Raise bow high enough to clear workpiece.
Make sure blade is not in
contact with workpiece when motor is
started.
3. Place stock between vise jaws, set stock for
desired width of cut and tighten vise. (See
Figure 9-3 for recommended placement in vise
of varied workpiece shapes.)
