Engine Oil Pressure; Cooling System - Yale VERACITOR GCC030VX Operating Manual

Maintenance

Engine Oil Pressure

NOTE: The engine will enter shutdown mode after a warn-
ing buzzer sounds and a 30-second countdown if engine oil
pressure is less than 34.5 kPa (5 psi) on lift trucks with
powertrain protection system. Lift trucks equipped with a
Yanmar diesel engine will enter shutdown mode when the
engine oil pressure is less than 49 kPa (7 psi) on lift trucks
with powertrain protection system. See the Engine Shut-
down procedures in the Operating Procedures section in
this manual.
There is an indicator light for the engine oil pressure on the
Display Switch Cluster. During normal operation the red
indicator light will illuminate when the key switch is turned
to ON, if the truck is equipped with a key switch, or when
the power ON/OFF button is pressed, if the truck is equip-
ped with a keyless option, and will stay illuminated until cor-
rect minimum oil pressure is obtained, at which time the
light will go off. If the light continues to stay on when the
engine is running, the engine oil pressure is low. Stop the
engine and check the oil level. See Figure 33, Figure 34,
or Figure 35. Do not restart the engine until the low pres-
sure condition has been corrected.

Cooling System

WARNING
DO NOT remove the radiator cap from the radiator
when the engine is hot. When the radiator cap is
removed, the pressure is released from the system. If
the system is hot, the steam and boiling coolant can
cause burns.
NOTE: The engine will enter shutdown mode after a warn-
ing buzzer sounds and a 30-second countdown if coolant
temperature reaches 121 °C (250 °F) or above, on lift
trucks with powertrain protection system. Lift trucks equip-
ped with a Yanmar diesel engine will enter the shutdown
mode when the coolant temperature reaches 110 °C
(230 °F) or above on lift trucks with powertrain protection
system. See the Engine Shutdown procedures in the
Operating Procedures section in this manual.
There is an indicator light on the Display Switch Cluster for
the coolant temperature. The red light is ON when the key
switch is in the START position or the Power ON/OFF but-
ton is pressed, and must go OFF when the engine is run-
ning. If the light is ON when the engine is running, the
coolant and engine are too hot. Stop the engine and check
