recommends following the guidelines in this document during times when:
•
The coach can be operated on a regular/weekly basis while in storage.
•
The coach will be in storage for an extended period of time without any operation.
•
The coach will return to service following an extended period of downtime.
The following recommendations are general in nature for all coaches but should be modified to
meet each customer requirements as needed.

Check the fluid levels.
Start the coach for 30 minutes to circulate fluids and charge up the batteries.
Turn on the passenger HVAC system, run for 15 minutes in heat mode and then
15 minutes in air conditioning mode. Verify starting temperature and end
temperature.
Move the unit to circulate transmission fluid, rotate tires, lubricate the wheel seals,
and check the brakes.
Road test to operating temperature and highway speed if circumstances allow.
When parking, try to avoid flat spots on the tire. Make sure the tires will be in a
different position.
START UP RECOMMENDATIONS
CAUTION
Ensure all proper PPE (Personal Protective Equipment) is worn prior to working on the vehicle.
IMPORTANT NOTE
After a coach has been parked for an extended period, an inspection of the unit is required to make sure
all items are intact and in good working order.
