Oscillate Raised Relay K12

Terminal 30 of the Oscillate Raised relay, K12,

receives power from the Power relay, K2. When

power is cut to terminal 86 of K2 via key switch or

either Emergency Stop button, power to terminal

30 of K12 will be lost.
Terminal 86 of K12 receives power from pin J1-

A4 while driving is engaged and the ECM is

powered.
J1-A4 is disabled when an outrigger is lowered to

the ground.

Oscillate Limit Switches S50, S51

The right and left oscillating limit switches,

S50 and S51 respectively, are normally closed

limit switches, held in the open position when the

machine is on a level surface.

When the left rear or right rear wheel 'drops', the

limit switch will relax and close its circuit, sending

power to the appropriate oscillating valve coil.
