Operating Instructions
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.
Allow the engine to cool before draining and flushing the cooling system.
Water containing more than small concentrations of salt or minerals should not be used in the
cooling system. Salt facilitates corrosion and minerals deposited on the coolant passage walls.
Both processes inhibit proper cooling.
