(7) Right slider track. (8) Left slider track. (9) Scissor arm. (10) Rack. (11) Shock absorber. (12) Adjustment knob.The suspension of the seat performs several functions:
Isolation
Automatic Weight Adjustment
Height Adjustment
Connection to the SeatIsolation and Weight Adjustment
Air bag (5) acts as a spring as the air is compressed due to the motion of inner scissor arm (9) relative to lower housing (6). The amount of air that is in the air bag is determined by the operator. (Refer to "Height Adjustment".) The pressure in the air bag is determined by the weight of the operator. This provides automatic weight adjustment.Damping Adjustment
Rotary Knob Adjustment
Illustration 3 g00883101
Damping is provided by shock absorber (11). The stiffness of the shock absorber may be adjusted by rotating knob (12). Turn the knob counterclockwise for more stiffness. Turn the knob clockwise for less stiffness. The knob does not have much range of movement.Up / Down Lever Adjustment
Illustration 4 g00885977
Damping is provided by lever (14). Pull UP on lever (14) in order to increase the damping of the suspension. Push DOWN on the lever in order to decrease the damping of the suspension.Ride Indicator
Ride indicator (13) must be aligned in the green zone when the machine is not running.Height Adjustment
Using the Toggle Switch
The height of the seat is determined by the volume of air in air bag (5). To raise the suspension, the operator holds toggle switch (2) upward and air enters air bag (5). To lower the suspension, the operator pushes down on toggle switch (2) and the air in air bag (5) is released. Note: The operator must not change the height of the suspension so that the stroke is inadequate for the particular application. The suspension height must be changed if the seat bottoms out excessively or if the seat bounces to the maximum height too much.The UP position of toggle switch (2) completes a 24 volt circuit from harness terminal (1) to compressor (3). Compressor (3) provides pressurized air to air bag (5) .The DOWN position of toggle switch (2) completes a 24 volt circuit from harness terminal (1) to solenoid (4). The solenoid opens an exhaust port for air bag (5) .Using the Air Valve Knob
Illustration 5 g00883176
The height of the seat is determined by the volume of air in air bag (5). To raise the suspension, the operator pushes in air valve knob (16) and air enters air bag (5). To lower the suspension, the operator pulls out air valve knob (16) and the air in air bag (5) is released.Note: The operator must not change the height of the suspension so that the stroke is inadequate for the particular application. The suspension height must be changed if the seat bottoms out excessively or if the seat bounces to the maximum height too much.When air valve knob (16) is pushed in, a 24 volt circuit to compressor (3) is completed. Compressor (3) provides pressurized air to air
