ENGINE OPERATION - Operating Instructions using the retarding power of the engine alone and more braking power is required, switch the two-position selector switch to the “LOW” position and activate the engine brakes by switching the “ON/OFF” switch to the “ON” position. If the vehicle’s drive wheels begin to skid or there is a fishtailing motion, switch the “ON/OFF” switch to the “OFF” position. If traction is maintained when the engine brakes are activated and more braking power is required, move the two-position selector switch to the “HI” position. Again, if the vehicle has lost traction or if there is a fishtailing motion, switch the “ON/OFF” switch to the “OFF” position.
DO NOT attempt to use the engine brakes in the “HI” position. 1 Y53-1166-1G1 (08/2018) 27
