WARNING: Do not take transmission out of gear when going down a steep or long grade. You may not be
able to get the transmission back in gear, and the drastic slowing of engine speed could reduce air pres-
sure supply to the air brake system, and result in a reduction of brake capacity.
ENGINE HIGH IDLE SWITCH
The high idle control on the TCRE positions the throttle lever at high idle when air supply pressure is
insufficient for normal operation of the throttle system. This allows the engine to be warmed while the air
system is being charged. The high idle can be activated by the electric toggle switch located on the instru-
ment panel when air system is at normal operating pressure. With the transmission in neutral and the park-
ing brake applied, move toggle switch to high position to raise speed to a constant high idle. Before shifting
into gear, return switch to low position.
CAUTION: High idle must not be engaged except when transmission is in neutral and parking brake is
applied.
ENGINE WARNING SYSTEM
Your unit may have an optional 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 degrees F.
The driver should check antifreeze before taking unit into cold climate. For protection to 92 degrees F. below
zero, the mixture should be 68 percent antifreeze and 32 percent water. Never have more than 68 percent
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.
GASOLINE ENGINE MAINTENANCE INSTRUCTIONS
IMPORTANT:
The maintenance instructions here on pages 56 thru 58 are provided and intended for the
gasoline engine only.
Some components and systems will need to be serviced more frequently than others depending on the
severity of use. The engine lubrication schedule shown on the chart should be followed if the vehicle is driven
more than fifteen miles daily and is operated continuously for more than thirty minutes. If any of the follow-
ing circumstances exist, the engine oil and oil filter should be changed at every 3000 (5000 kilometers) mile
interval.
•
Operation in dusty areas.
•
Towing a trailer.
•
When most trips include extended idling and/or frequent low speed operation.
•
When most trips are less than ten miles and outside temperatures remain below freezing.
