Lift Reset Switch - Toro ProCore 648 Service Manual

Lift Reset Switch

The lift reset switch is located on the control panel (Fig.
21). This momentary rocker switch raises the coring
head in instances when the coring head has been
stranded in the aerating (lowered) position (e.g. engine
runs out of gas, coring head stuck). By depressing the
lift reset switch, the coring head lift system will reset, the
coring head will raise fully and normal coring head op-
eration can resume.
The switch terminals are marked as shown in Figure 19.
The circuitry of the lift reset switch is shown in the chart
below. With the use of a multimeter (ohms setting), the
switch functions may be tested to determine whether
continuity exists between the various terminals for each
switch position. Verify continuity between switch termi-
nals.
