Question 41

Antilock Braking System

Answer 41

– ABS also allows for Anti-Slip-Resistance (ASR) feature. If one wheel is off the road, spinning, ASR will apply that brake to increase torque to the other wheel, allowing it to pull the apparatus out. – If both wheels are spinning, ASR will reduce the engine torque to match the conditions. – ASR is completely automatic, the driver does not need to do anything.

Question 42

ASR

Answer 42

Sometimes, you may not want the ASR to work at 100%, such as when trying to climb out of deep mud or snow, loose dirt or sand. – In that case, press the Off Road Traction Control switch. This will allow some slippage (spinning) to assist in climbing out. – Press again to turn off. It will also reset with the ignition switch cycling.

Question 43

Stability Control

Answer 43

Roll stability control (RSC) senses when a rollover may occur and intervenes by reducing throttle, application of the retarder, and/or selective brakes. – Electronic Stability Control (ESC) compares where you are steering and where you are actually going (skidding) and tries to correct by selectively applying the brakes and throttle/transmission. * The driver still needs to provide steering input.

Question 44

Question 51

Cavitation Protection

Answer 51

If PSG cannot recover, it switches to RPM Limit Mode. * Pressure LED stays on. * Displays flash and states Operator / RPM Limit. * Pressure Setting Does not change, but Preset is disabled. * PSG acts like manual throttle. * If pressure recovers or operator corrects, returns to Pressure Control Mode – normal operation. * If it does not recover but stays above 45 psi, remains in RPM Limit Mode. If pressure falls below 45 psi, but above 15 psi, enters Lo Water Mode – Displays Lo Water – Sets rpm at 1100 – After seven seconds goes to idle. * If pressure falls below 15 psi, enters No Water Mode – Displays No Water – Goes to idle.

Question 52

Pressure correction

Answer 52

In the RPM Limit, Lo Water, No Water Modes, if the pressure recovers, it goes back to Pressure Control. If the operator intervenes and brings the RPMs to a point where it is not in cavitation, it goes back to the Pressure Control Mode. * If it goes to idle and stays more than 3 minutes, it enters the Idle mode and cancels the pressure setting.
