The air pressure gauge must be in the operating (GREEN) range.
3. Apply the service brake. 4. Release the parking brake.
Brake damage can occur if the machine is moved with the brake applied.
5. Raise the scraper bowl just high enough to clear obstacles. 6. Turn the neutral lock OFF. 7. In one quick motion, move the transmission range selector to the highest desired speed. The engine can be started with the transmission in other than NEUTRAL. However, the machine will not move.

Stop the machine immediately if the low air pressure indicator goes on, or the electric warning horn sounds. There may be a malfunction of the air and brake system.
After an emergency stop, be sure the air pressure is in the operating range before moving the machine.
Later Machines
Pull the button out to apply the emergency brakes if the service brakes fail.The emergency brake will be applied automatically if the air pressure in the reservoirs drops below 280 kPa (40 psi).
If the air pressure drops, or if the emergency brakes are applied, be prepared for a sudden stop.Have your seat belt properly adjusted at all times.
Earlier Machines
Move the parking/emergency brake lever to EMERGENCY to stop the machine, if the service brakes fail.The parking/emergency brake will apply automatically if air pressure drops below 280 kPa (40 psi) in the reservoirs.
Move the lever to PARK when the machine stops. With the lever in EMERGENCY, the brakes could be released if the air pressure is lost completely.
