The battery can discharge if snow or ice short circuits the terminals. Keep the battery
posts and cable connectors clean and dry. Remove any corrosion with a solution of
soda and water.
During extremely cold weather, it is advisable to remove and store the battery in a
heated area when the crane is to remain idle for any extended period.
Water added to the battery can freeze before it mixes with the electrolyte.
During very cold weather, add water to the battery just prior to, or during
operation of the crane. If the crane is not to be run, water may be added if an
external charger is connected to the battery.
5. Cold, sluggish oil can cause pump cavitation. If the crane is not equipped with a
reservoir immersion heater and running the oil over relief will not warm it sufficiently to
prevent pump cavitation with the engine running very slowly, cease attempts to load
the hydraulic system until an external heat source can be obtained.
The hydraulic oil may be run over relief to aid in the warm-up process. To do this,
actuate a function, allow the cylinders involved to reach the limits of their travel and
hold the control in the engaged position for a few seconds.
When running hydraulic oil over relief to warm it, be sure to restrict the flow to as slow
a speed as possible by moderating pressure on the controls being engaged and
running the engine at low speed.
Continue warming the oil and slowly cycle all crane functions, actuating all cylinders in
turn, swinging the upper and operating the winches in both directions.
6.
At the end of the work period, or whenever the crane is to be left idle for extended
periods, prevent it from being frozen to the ground by parking it on a wood, concrete,
asphalt or mat surface.
EXTREME HEAT
Like extreme cold, extreme heat requires that precautions be taken with respect to the
cooling system, the battery and lubrication. Protect the crane by performing the following
recommended procedures:
1.
High temperatures necessitate the use of lubricants which are both more viscous and
which resist deterioration at higher operating temperatures. Refer to the Lubrication
Chart and lubricate the crane using the lubricants recommended for the expected
temperatures.
Crankcase oil is particularly important because it helps dissipate heat. Check the oil
level frequently and add oil as necessary to maintain required level. Too little oil will
hinder heat dissipation.
2. To ensure proper coolant circulation, drain and flush the cooling system, clean any
foreign matter from the radiator cooling fins and through core air passages, replace
defective hoses, tighten hose clamps, inspect water pump drive belt properly,
eliminate any leaks detected and fill the system with a 50% solution of ethylene glycol.
A corrosion inhibitor is recommended by the engine manufacture.
