8. BI-METAL SPEEDS AND FEEDS
These figures are a guide to cutting 4"(100mm) material
(with a 314 Vari-Tooth) when using a cutting fluid.
Increase Band Speed: 15% When cutting
1/4"(6.4mm) material (l0/l4 Vari-Tooth)
12% When cutting 3/4"(19
mm) material (6/10 Vari-Tooth)
10% When cutting
1-1/4"(32 mm) material(5/8 Vari-Tooth)
5% When cutting 2-1/2"
(64 mm) material(4/6 Vari-Tooth)
Decrease Band Speed: 12% When cutting 8"(200mm)
material(2/3 Vari-Tooth)

TELLTALE CHIPS
Chips are the best indicator of correct feed force. Monitor
chip information and adjust feed accordingly.
Thin or powdered chips – increase feed rate or reduce
band speed.
Burned heavy
chips – reduce feed rate
and/or band speed.
Curly silvery and warm chips –
optimum feed rate and band
speed.
9. ASSEMBLY
A 3/4 HP, motor, split phase or capacitor-start it
recommended for best economical performance.
Counterclockwise rotation is required. Note that rotation
can be reversed by ollowing directions
given on terminal or nameplate.
(1). Assemble the motor Mounting plate to the head using
the long bolt Note that the flat side of the plate faces up.
(2). Assemble the guard plate to the head using the
screw and Lock Washer and the Carriage Bolt Washer
and Wing Nut are used to secure the motor mounting
plate to the Guard plate through the slotted hole in the
Guard plate. These components also serve to position
and lock the motor in place for proper speed/ belt
adjustment.
(3). Place the spacer over the long Bolt and secure it wit
the nut .
(4). Secure the Motor to the Motor Mounting plate with
the four bolts and nuts. Note, that the motor shaft is
placed through the large opening in the Guard plate and
must be pareallel with the drive Shaft.
(5). Assemble the Motor Pulley, the smaller of the two
provided, to the motor shaft Note, the larger diameter
must be closest to the motor.
