Horizontal Band Saw
13.6 ADJUSTING FEED RATE
Rate of feed is adjusted with control dial (E, Fig. 10-1).
Feed rate is important to band saw performance;
excessive pressure may break the blade or stall the saw.
Insuffi cient pressure rapidly dulls the blade.
Material chips and shavings are the best indicator of
proper feed pressure. The ideal chip is thin, tightly
curled, and warm to the touch. Chips that range from
golden brown to black indicate excessive force. Blue
chips indicate extreme heat from too high a blade speed;
this will shorten blade life. Thin, powdery chips indicate
insuffi cient feed pressure.
13.7 OPERATING VISE
The workpiece is placed between the vise jaws with the
required amount to be cut-off extending out past the blade.
1.
Place workpiece in cutting position. Lift up pawl (G,
Fig. 13-5) and slide jaw close to workpiece.
2.
Turn handwheel (H) clockwise for a fi ne adjustment to
create a 5 to 6 mm (1/4 in.) gap with workpiece.
3.
Turn clamp switch (see J, Fig. 10-1) to the right to
clamp the workpiece.
4.
Perform cut.
5.
Release clamping pressure via the switch (J, Fig. 10-
1).
6.
Lift pawl (G) and manually retract vise jaw.

13.8 ADJUSTING STOCK ADVANCE STOP
The Stock Stop is used mainly for repetitive cuts of the
same length. Install the stock stop assembly to the ma-
chine bed with two hex bolts.
Position the stop block (J, Fig.13-6), and adjust the rod
(K) the desired distance away from the blade. Securely
tighten the handle on the stop block, and the screw on the
rod holder.
The stop may also be adjusted out of the way when not
being used.
13.9 GENERAL OPERATING PROCEDURE
1. Select the proper speed and blade for the type of
material you are cutting.
2. Make sure blade tension is adjusted properly.
3. Make sure the left blade guide bracket is adjusted
as close as possible to the left vise jaw, without causing
obstruction.
4. Use the controls to raise the saw head, and turn the
feed rate dial to zero.
5. Place the stock between the vise jaws, position the
stock for the desired length of cut and tighten the vise.
6. Start the blade and turn on coolant system. Adjust
coolant fl ow using the individual valves.
7. Set feed rate until saw blade begins to lower at desired
rate of speed.
8. Proceed to cut through the workpiece. The blade will
shut off at end of cut in manual mode; the saw head
will return to raised position in auto mode.
