(3) First stage conveyor pump pressure test port. (4) Fan pressure test port.1. Connect a 34 450 kPa (5000 psi) pressure gauge to pressure test port (3).2. Connect a 34 450 kPa (5000 psi) pressure gauge to pressure test port (4).3. Run engine at high idle and move conveyor switch to the on position.4. Measure the pressure going to the first stage conveyor motor and the fan by reading the pressure gauge values. Use the following equation to calculate the first stage conveyor pressure reading:Test port (3) - Test port (4) = First stage conveyor pressure.5. The first stage conveyor pressure should be ... 5200 1380 kPa (750 200 psi) Second Stage Conveyor Pressure Test

(5) Second stage conveyor pressure test port.1. Connect a 34 450 kPa (5000 psi) pressure gauge to pressure test port (5).2. Run engine at high idle and move conveyor switch on, and set second stage conveyor speed control dial to maximum speed.3. Measure the pressure going to the second stage conveyor motor by reading the pressure gauge. The gauge should read ... 5500 1380 kPa (800 200 psi) To obtain an accurate pressure reading the second stage conveyor speed adjustment knob (located on the operators console) must be at 100% speed with the engine at high idle. The second stage conveyor pressure is not adjustable. It is preset at the factory.First Stage Conveyor Relief Pressure Test
Refer to Warning on the first page of Testing And Adjusting section.

(3) First stage conveyor test port2. Connect a 34 450 kPa (5000 psi) pressure gauge to pressure test port (3).3. Run machine at 1100 RPM.4. Move conveyor switch to the ON position, and carefully watch the pressure gauge. The gauge should read 24 100 kPa (3500 psi) just before the relief valve opens. The relief valve is not adjustable . It is preset at the factory.Second Stage Conveyor Relief Pressure Test
