DO NOT exceed 650 psi (45 bar). Close the pump

needle valve on the pressurizing unit.

12. Watch the pressure gauge on the pressurizing unit

to ensure that the pressure in the park brake system

does not drop during the towing operation.

the machine to a secure location.

14. When towing is completed, remove the pressurizing

unit and replace the cab floor.

WARNING

BLOCK ALL FOUR WHEELS. Failure to do so could

result in machine roll-away.

CAUTION

DO NOT exceed 650 psi (45 bar) when pressurizing

the park brake. Applying to much pressure may
