REVIEW OF THE CONTROL PANEL:
The following section describes the various Control Panel switches, controls, and indicators, as
displayed in Figure 2.
Looking from Right to Left:
On/Off Circuit Breaker:
This switch controls line power to the edger and vacuum. It contains an
integral 20 amp resettable circuit breaker for overload protection.
Tracking Pressure Gauge/Regulator Control Knob:
The pressure gauge indicates the pressure of the pattern against the pattern
roller and the pressure of the bevel guide wheel on the lens. It is factory set at
35 psi, and, if required, can be adjusted by turning the knob directly under the
gauge.
Chuck (Blue -
This button simultaneously activates the lens and pattern clamps. Since the
pattern is spring clipped on, the operator's left hand is free to hold the lens
during chucking.
Rimless (Grey -
With this button engaged, the edger cuts the lens to a straight rimless finish.
Note: Activating the rimless lock control does not correct for size. The
running of a rimless job will be covered later.
