Maintain batteries at full charge. The MS52131 slave receptacle may
be used for charging the batteries or slave starting the engine from an
external power source.
Check cold start ether aerosol container. When starting using ether
spray, inject with two-second spurts while cranking cold engine. Never use
with warm engine.
Keep the crane clean of ice and snow, especially the boom.
Depending on the temperature, allow ample time (15 to 30 minutes at
0 F) to warm up the engine. Allow additional time to warm up the hydraulic
oil. Cycle the functions slowly at first to raise hydraulic oil temperature.
In freezing weather, park the crane in an area where it cannot be frozen
to the ground.
Before lifting a load, make sure it is not frozen to the ground.
HOT WEATHER OPERATION.
If sustained temperatures approaching 1200F are experienced during
craning operations, care should be taken to ensure adequate cooling of the
engine and drive components. Keep the radiator clear and full of coolant and
the cap tight. Keep the radiator, grill, and engine oil cooler clean. At ambients
between 115 to 1200F, it may be desirable to replace the 50-50
antifreeze/water solution in the engine cooling system with pure water plus
At ambient temperatures of 1200F and above, tolerances in the temperature
sending units may account for an indication that the engine coolant (and/or
the transmission coolant) has overheated. If a continuous warning occurs
for 3 minutes, unload the engine and allow the unit to cool. If warnings
persist, shut down the machine and find the cause.
Constant crane operation at high ambients will result in premature break-
down of the MIL-L-2104 hydraulic oil. 500 hours at high temperatures on
this oil, should be followed by draining and replacement with fresh oil.
