Back Section Positioning

Back Section Release Mechanism

When either back release handle is squeezed, linkage rotates the cam. The rotating cam pushes the plunger down, compressing the cylinder pin. When the cylinder pin is compressed, the pressure inside the cylinder is released, allowing the back section to be repositioned.

When the back handle is released, the cam and plunger return to their normal position. This removes pressure from the cylinder pin allowing the cylinder to pressurize and lock the back section in place.

Upholstery Heater System

Upholstery Heater Operation

With the heater system's power cord properly connected, 115 VAC is supplied to the upholstery heater PC board thru the distribution board.

Note

Current does not flow thru the two fuses on the distribution board. The distribution board is merely a connection point for the upholstery heater system.

The two fuses (F1 & F2) on the uph. heater PC board protect this system from excessive current.

Circuitry on the upholstery heater PC board reduces the line voltage, and supplies approximately 12 VAC to the upholstery heater switch.

When the upholstery heater switch is pressed ON, the switch illuminates and 12 VAC is supplied to the two upholstery heating elements. When the heating elements are energized, they warm the back & seat sections of the upholstered top. Pressing the heater button again, turns the heater system OFF.
