Interlock Lever Switches

The two interlock lever switches are located on the han-

dle (Fig. 9). The lever switches are normally open and

close when the lever is raised to the handle. The inter-

lock lever switches are used to permit engine operation

when the coring head is lowered and also allows the

traction drive lever to be retained in the engaged posi-

tion.

Testing

1. Unplug the switch connector from the machine har-

ness.

2. With the use of a multimeter (ohms setting), deter-

ine whether continuity exists between the switch con-

nector terminals for each switch position.

minals.

4. After testing, plug the switch connector into the ma-

chine harness.
