the oil in the engine and check for leaks. If the oil level is at the correct
level and there are no leaks, it is an unserviceable lubricating system.
Send the crane to the factory for repair.

Engine coolant temperature gauge
1
The coolant temperature must be between 158°F and 203° F (70°C and
95°C). Do not move the crane at high speed when the coolant
temperature is less than 158°F (70°C).
2
Do not operate the engine at high speeds without a load for extended
periods of time.
Do not move the crane at high speeds with a heavy load until the engine
coolant temperature is a minimum 158°F (70°C).
3 When the coolant temperature is in the yellow area, between 203°F and
212°F (95°C - 100°C), the engine is too hot. Park the crane. Operate the
engine at a RPM immediately above idle to help cool the engine. Or, as
you move, put the transmission in a lower gear range to decrease the
load on the engine.
Do not stop the engine immediately when the engine coolant temperature is
above the maximum limit. If you stop the engine, the coolant temperature
increases suddenly and damage to the engine occurs. Operate the engine
at a RPM immediately above idle to help decrease the coolant temperature.
4
When the coolant temperature gauge points to the red area, between
212°F and 248°F (100°C - 120°C) continuously, it shows that the engine
is above limits. If you stop the engine, the coolant temperature increases
suddenly and damage to the engine occurs. Operate the engine at a RPM
immediately above idle to help decrease the coolant temperature.
5
When the coolant temperature goes back to the green or yellow area, do
the items that follow:
Examine the engine area for leaks.
Examine the function of the thermostat.
Check the coolant level.
Check the fan belt for damage.
Make sure that the fan belt is not too loose.
Do not add a large quantity of cold water to the engine if the engine coolant
