DESTINATION SIGN
DESCRIPTION
The destination sign is located above the front windshield.
An optional side destination sign is mounted on the right hand
front side of the coach.
'AINTENANCE
It is recommended that the fo)lowing inspections and
checks be made on a regularly scheduled basis:
1. Check to see if mechanism runs free and easy. Crank
handle on destination sign; if it seems to bind. check gears for
lodgement of foreign objects.
2. Check for loose items such as wires, clips, hanging tape,
etc. Repair or remove such items.
3. Inspect the inside of the destination sign compartment
Remove dirt and foreign objects. Clean inside of compartment
well and keep door closed.
4. If curtain is loose on rollers, run curtain to one end and
turn crank handle until curtain roll is tight on roller. Run
actuating !mechanism through full cycle of curtain and repeat
tightening action on opposite end of curtain.
5. The destination sign mechanism has nylon gears; there-
fore. no lubrication to the mechanism is required.
SIGN CURTAIN REPAIR
In the event a destination sign curtain is torn, it can be
repaired with 3M polyester tape or any equivalent cellophane
tape. When repairing a tear. the tape should be used on both
sides of the curtain.
When it becomes necessary to install or add curtain inserts,
butt splice or overlap and apply strip of
3
/4" (19.0 mm) wide
polyester tape over front and rear seam. •
The above method is an easier and more accurate way of
installing inserts than the sewn methods. It also makes for
considerably less bulk and better turning of curtain rolls.

the lock lever located at left front of seat. When seat is positi-
oned. release the lever. The back of the seat cushion can be
tilted up or down by grasping the large knob at left corner of

raise. Seat may be raised by grasping and firmly pulling seat
frame up. To tower, raise seat to highest position. then lower
