Air Line Schematic (1) Air dryer (2) Service Brakes (3) Air Compressor Governor (4) Junction Blocks (5) Air Compressor (6) Pressure Switches (Low Brake Air) (7) Air Gauges (8) Pressure Switch (Brake Air) (Stop Lamp) (9) Air Control Valve (Service Brake) (10) Air Horn (11) Solenoid Valve (Air Horn) (12) Solenoid Valve (Parking Brake) (13) Air Control Valve (Parking Brake) (14) Check Valve (Parking Brake Release) (15) Pressure Switch (Brake Air) (Parking Brake) (16) Transmission Flange (17) Relief Valves (Air Tank) (18) Check Valves (Air Tank) (19) Drain Plugs (20) Air tankNote: Air compressor governor (3) senses low air pressure only from the left side of the tank.Note: Pressure switch (8) is part of the front wiring group.Attachments for the machine include the following items. (1) The air dryer is an attachment. (10) The solenoid valve for the air horn is an attachment on the standard machines. (11) The air horn is an attachment on the standard machines.The brake system is actuated by direct air. There is a brake that is located at each rear wheel. Air compressor (5) sends air pressure to air tank (20). This air is sent through two check valves (18) for the air tank. Air can only flow in one direction through the check valves. The air tank is divided into two separate sections. Each section of the air tank has a relief valve (17) and a drain plug (19) .Air pressure flows from air control valve (9) for the service brake in order to activate the brakes. The brakes are activated by independent circuits. The independent circuits are for the right side of the machine and the left side of the machine. The air tank can provide enough air pressure in order to actuate the brakes five times after the engine stops and the air compressor stops. In case an air line fails or a circuit fails, one section of the air tank will still have air pressure. The air pressure will be used to engage the brakes on one tandem drive.
