Towing Procedures
Towing must be from the FRONT.
Only tow from the rear to extract the coach from
ditches or snowbanks.
Only operators authorized to and experienced
in towing intercity coaches may tow coaches.
DO NOT INSTALL SOLID PLUGS.
1. Remove the 1/4 NPT threaded mufflers to
install the fitting style required by the tow truck.
2. Route the tow vehicle hoses to the coach
connection points.
Route the hoses away from the steering gear
and linkage.
Ensure that the tow hoses will not be pinched
or damaged during towing
.
3. Use the TOW SUPPLY connection for the
supply line from the tow vehicle.
4. Use the TOW BRAKE connection for the line
from the tow vehicle that operates the service
brakes.
If this line accidentally detaches or is severed
while towing, the parking brake will activate.
5. Connect the coach to the tow vehicle.
Disconnect the drive shaft or remove the axle
shafts, before towing the coach. See Section
3F – Towing, in the Maintenance manual for
axle shaft removal procedure.
Reinstall the muffler when towing is
completed. The connections must vent to
atmosphere for the parking brakes to release
properly.
If it is necessary to cage the drive axle spring
brakes, see Section 4 of the Maintenance
Manual. Always use extreme caution around
spring brakes.
