NEUTRAL START AND REVERSE WARNING CHECKS
IMPORTANT: Perform these checks before operating machine REVERSE WARNING ALARM CHECK: NEUTRAL START CIRCUIT CHECK:
- Be sure area around machine is clear of personnel. - Ensure the Master Switch is ON. - Engage the parking brake. - Completely depress the inching control pedal. - Move transmission control lever to first gear - Reverse. - LISTEN: The reverse warning alarm must sound. - Be sure area around machine is clear of personnel. - Ensure the Master Switch is ON. - Disengage the parking brake. - Move transmission control lever to the forward position. - Turn the key switch to START. - LISTEN: The starting motor must not turn the engine.
- Move the transmission control lever to the reverse position. - Ensure the Master Switch is ON. - Disengage the parking brake. - Turn the key switch to START. - LISTEN: The starting motor must not turn the engine.
Inching control pedal....................................See page 37 Transmission control lever...........................See page 39

Stopping and starting with display indicating a gear higher than 4 (observe this will be higher than 3 on future machines) Starting machine
Inching pedal
Starting engine
Down shifting
Upshifting
Shifting while descending steep grades
Shifting forward to reverse and reverse to forward
Parking brake
Lugging engine down under heavy blade or ripper load TRANSMISSION OPERATING INSTRUCTIONS
Stop using inching pedal machine will always select 4th gear to start.On level terrain or moderate grades start in 4th and upshift as conditions permit.On steep grades or when under load shift to lower gear and drive away.
Move gear selector to desired gear which will be indicated on display and drive away.Inching pedal can be used also in a manner similar to a mechanical clutch. Most operators will find this to be a very natural operation. Use when starting or stopping.Use for grader finishing work requiring “Creeper gear” or very slow speeds.Use for very slow ground speed work to increase engine speed for hydraulic performance (This should rarely be necessary because of the wide range performance of the hydraulic system).WARNING: Do not abruptly depress and release inching pedal to start a heavy load or free a stuck machine.
Transmission must be in neutral before engine can be started.
Downshift one range at a time do not lug down the engine below 1700 RPM. Watch tachometer. Power shift, do not use inching pedal. Upshift normally as speed, grade, and traction conditions permit. Power shift, do not use inching pedal. During transport, while descending short, steep grades, the engine may be driven from the ground by the wheels. In order to maintain a higher speed it could be necessary to upshift to protect the engine while using brakes for retardation. Normally the safe and recommended procedure is to descend slowly using a lower gear together with the brakes, particularly for longer distances. Operator can make these shifts as required by normal working conditions. The transmission will automatically select the appropriate gear in the opposite direction and it has built in shock protection. Transmission will not engage a gear with park brake on.
Do not repeatedly depress and release inching pedal to force movement of machine.
