PREVENTATIVE MAINTENANCE SCHEDULE
The following Maintenance Schedule is provided as a convenient reference for the specifi ed systems and components, which require periodic service.
These schedules are not intended to be a complete list of all possible services to be performed on a regular basis, nor is it suggested that more frequent services not be considered.
Because of the different types of operations coaches are subjected to, the severity of service must be considered when establishing maintenance intervals. Therefore, any such intervals given in the following schedule must be adjusted according to the particular type of operation in which your particular vehicle will be used. The intervals given are Krystal Enterprises, Inc. recommendations and should be considered as maximum intervals. It should be noted that maintenance inspection and service operations of shorter intervals are always preferable to longer intervals.

Basic Troubleshooting Guide
The following section details basic troubleshooting techniques that will help you to understand and determine the best course of action regarding some commonly encountered problems.
PROBLEM
VIBRATION: Noises or Vibration at high speeds only, or in a certain range of speeds:
POSSIBLE SOLUTIONS
A certain range of speeds indicates a damaged or otherwise out-of- balance drive line, Contact the Service Dept. Only SELECT drive line shops that are qualifi ed to properly balance the multiple drive line ex- tensions used in your bus. The Krystal Service Dept. can recommend one near you.
REAR A/C BLOWER INOPERATIVE Check to make sure the FORD front A/C unit is on. If the rear A/C is
MOVING CARGO PARTITION TO ADD ADDITIONAL SEATING Caution: Do Not Exceed Weight Distribution/Payload Limitations EXTERIOR LIGHTING
SLIDER WINDOWS HARD TO OPEN AND CLOSED
still not working, call the Krystal Service Dept. Remove seats in front of the Partition Wall and loosen all four bolts securing the wall. Then go behind the wall and remove the channel nut on the fl oor, this will allow the wall to be move back and then additional seating can be installed. Note: torque Seat Bolts to 35 ft. lbs. E-450: One or all exterior clearance lights inoperative, please refer to the FORD wiring schematic in the Krystal Electrical Schematic Manual F-550: Exterior running lights work off of the Krystal relay board. If any of the windows start to stick during opening or closing, simply spray both side tracks with silicone spray and work the windows a few times to lubricate the tracks. This should be done approximately every three months.

Basic Troubleshooting Guide
PROBLEM
POSSIBLE SOLUTIONS
PAGING SYSTEM INOPERATIVE
NO TELEVISION RECEPTION
REAR VCP & TV INOPERATIVE
EXTERIOR SEALANTS CRACKING OR LIFTING
Check the 5 amp fuse on the circuit board above the driver. Wiring schematics and instructions for the paging system are located in this manual on page 23. If the TV has power, but you cannot pickup any stations, make sure VCP mode button on the P.A. System is engaged and the VCP power button is engaged. Check to make sure all connections on the back of both units are tight. Check the fuse located at the front face of the TV, and on the backside of the VCP. If the exterior seams of the bus ever crack or start lifting, simply clean the area with rubbing alcohol or mineral spirits completely. After this has been done you can remove the old silicone by using a sharp knife or razor cutter. Clean the area again with the above cleaners and apply a thin bead of white exterior silicone and smooth the bead with your fi nger for a smooth appearance.
REAR ELECTRIC STEP INOPERATIVE Check to make sure the step switch is turned on. This switch is located
inside the cargo area on the right hand sidewall. If this will not power up the step, call the Krystal Service Dept. The rear step should be lubricated every 30 days to ensure proper operation of the step.
REAR STEREO/CD INOPERATIVE Check to make sure all connections are tight. Also remove the stereo
and check the fuse located on the backside of the stereo.

Basic Troubleshooting Guide
PROBLEM
CANNOT REMOVE WATER FROM LAVATORY
POSSIBLE SOLUTIONS
Make sure fresh water tank has water in it and the water pump switch is in the on position. NOTE: Always be sure to turn the water pump switch off when not in use. Failure to do so could cause a steady drain on the auxiliary battery or could cause damage to the water pump. The fresh water fi ll is located under the bus at the rear of the vehicle.
PASSENGER LIGHTS INOPERATIVE Check to make sure the switch on the overhead control panel is turned
BACK-UP ALARM INOPERATIVE
on. NOTE: There is a 5 minute light timer for the interior lights which will automatically turn them off when the door is open. The interior light switch needs to be turned on for at least 10 seconds to reset the timer. Check to make sure reverse lights are coming on, if not, check the fuse located in the FORD fuse panels.
