• DO NOT APPLY THE AIRPLANE BRAKES DURING
THE TOWING PROCEDURE. REGARDLESS OF THE
SPEED. USING BRAKES CAN CAUSE DAMAGE TO
THE AIRPLANE STRUCTURE AND/OR TO THE NOSE
LANDING GEAR. ONLY WHEN THERE IS A RISK OF
COLLISION OR DAMAGE TO THE AIRPLANE AND IN
ACCORDANCE TO THE TRACTOR OPERATOR, USE
THE AIRPLANE BRAKES TO STOP THE AIRPLANE.
After towing operation is finished:
− Set the emergency/parking brake and, with the airplane energized,
make sure that the brake light is ON.
NOTE: To prevent hydraulic fluid transference from system 1 to
system 2 or vice versa, always apply brakes with the pedals
before pulling and releasing the emergency/parking brake
handle.
− Make sure that nose wheel displacements are below the maximum
operational limit.
NOTE: Steering handle actuation with nose wheels beyond their
operational limits may cause damage to the nose wheel
steering system.
− Install the chocks forward and aft of the left and right main landing
gear wheels.
− Remove the airplane towing vehicle.
CAUTION:
CHECK WITH GROUND PERSONNEL IF THE NOSE
WHEEL IS NEAR THE CENTER POSITION (CLOSE TO
0º) BEFORE PRESSURIZING THE HYDRAULIC
SYSTEM.
− Pressurize the hydraulic system if it is depressurized.
− Engage the steering system through the steering handle. Check if
the STEER OFF message is not displayed on EICAS.
