7. 21 UNUSUAL OPERATING CONDITIONS
A. You must use caution when you operate in the conditions that follow:


Extreme Cold


Extreme Heat


Sandy or Dusty Job-Sites


High Altitudes


Storms
B. Extreme Cold
(1) If you operate in very cold areas, lubrication and battery malfunctions are usual.
Make sure that the crane is “winterized” by the service facility.
(2) Before you operate the crane, make sure that all fluid and oil levels are at the
correct level. You should use fluid and oil of recommended brand, type and
quantity.
(3) Keep the battery fully charged. Keep the battery in the building, if necessary.
(4) Drain the water from the cooling system.
(5) Remove the moisture in the air brake system.
Do not engage the PTO until the hydraulic oil is warm. If the oil is too
cold it does not flow correctly.
(6) You must know that the hydraulic oil becomes thick when you operate in very cold
weather. If you operate the crane and the hydraulic oil does not flow correctly,
you can damage the system. When the oil is warm, you can slowly move parts of
the crane to help increase the temperature of the oil. Do not try to operate the
cylinders quickly.
(7) At the end of the work period, park the crane in an area where it cannot freeze to
the ground (wood, concrete, asphalt, or mat).
C. Extreme Heat
When you operate in an area that is too hot, examine the indicators and gauges
frequently. Follow these precautions:
(1) Examine the engine oil frequently. If the engine is too low on the oil level, the
engine cannot cool correctly. If it is necessary to add oil to the engine, make sure
that you add the correct type of oil.
(2) Make sure that the engine coolant is at the correct level. Do not try to add water in
the coolant if the engine is hot. Do not add salt water to the coolant system.
(3) If the engine becomes too hot because of coolant loss, slowly add coolant while
