Basic Operation
To completely understand drum and rotor turning you must have knowledge
of the lathe itself.
Spindle
The spindle is a motor driven shaft that turns the arbor upon which the brake
drum or rotor is mounted. By turning the drum and holding a cutting tool
against the inner braking surface, metal can be removed.
Do not try to move any feed levers or dials without the drive motor running.
Damage may occur to the gear trains.
Control and Operating
Fig5 Control Panel
Spindle Motor Switch
(Item 1, Figure 5)
The spindle motor switch is a two position toggle switch. When switch OFF, all
power to the spindle motor is shut off. When switched ON, the spindle motor
starts. The spindle will begin to rotate.
Disc/Drum Switch
(Item 2, Figure 5)
This switch is a three position select switch. When the left side of this switch is
depressed, power is supplied to the Disc feed motor. When the right side of the
switch is depressed, power is supplied to the Drum feed motor. When the
switch is in the neutral position (centered), power to both motors is OFF.
Feed Timing Potentiometer
(Item3, Figure5)
You should turn on the knob clockwise, until you can get an ideal feed speed,
and then, you can refinish the drum or rotor.
Spindle Speed
Spindle speed is adjustable. Refer to the specifications Iisted on page 5 for
the RPM rating of each grove on the V-belt pulley for each model.
Spindle Speed Adjustment
This V-belt adjustment must be made with the lathe off.
