6. Turn the key switch to the ON position (with the engine not run-
ning), release the park brake switch, and have an operator seated
in the seat.
7. Pressurize the park brake with the pressurizing unit. Close the
pump needle valve.
8. Clear the area of all unnecessary personnel.
9. Carefully remove the wheel blocks from each of the four tires. Tow
the vehicle to a secure location.
IMPORTANT! Without engine power, service braking power is reduced.
Only the rear service brakes will function when the brake pedal is
depressed. Steering is not possible and the vehicle will only travel in the
direction that the wheels were last truned. Tow or push the vehicle at a
very slow speed!
CAUTION:
DO NOT exceed 575 psi (40 bar) when pressur-
izing the park brake. Applying too much pressure may damage
the brake seals.
