ENGINE WARNING SYSTEM
This unit is equipped with an alarm system to signal low oil pressure and high engine temperature. If the
engine temperature exceeds 210 degrees, or if the oil pressure drops below 6 PSI, a buzzer sounds and an
indicator light glows.
CAUTION: If the alarm system sounds, shut the engine off immediately. Operation of the engine after the
alarm sounds could cause serious engine damage.
ANTIFREEZE
The unit is equipped with a 50-50 solution of antifreeze and water. This mixture protects to -30
°
F. The
driver should check antifreeze before taking unit into cold climate. For protection to 92
°
F. below zero, the
mixture should be 68% antifreeze and 32% water. Never have more than 68% antifreeze.
CAUTION: Cold water should never be poured into the cooling system when engine is hot. Wait until
engine cools, then add coolant with engine running.
WARNING: Extreme care must be used when removing radiator cap. As coolant becomes hot, pressure is
built up in the cooling system. Rapid venting and/or removal of radiator cap will cause coolant to boil up
and spray out and can result in serious burns. Slowly vent off pressure before removing radiator cap.
FUEL & LUBRICANT REQUIREMENTS
QBRE units should take advantage of the high energy content and generally lower cost of No. 2 diesel
fuel. Experience has shown that diesel engines will operate satisfactorily on No. 1 fuel.
CAUTION: This coach is equipped with a center mounted 60 gallon fuel tank* and long filler neck. Use
caution when filling with a high delivery nozzle to prevent spillage.
WARNING: FUEL SPRAY MAY CAUSE INJURY, REMOVE CAP SLOWLY. Do not fill more than 95% of
liquid capacity.
Note:
60 gallon tank standard, 100 gallon optional.
RECOMMENDED LUBRICANT
CAUTION: Do not mix petroleum based and synthetic lubricants or different brands of synthetic lubri-
cants due to possible incompatibility. In addition there may be increased lubricant change intervals rec-
ommended for synthetic lubricants. Consult manufacturers label for lubricant requirements.
