ethylene glycol) and a corrosion inhibitor. 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;
c) Air circulation around the engine and battery must not be restricted. Keep air intake
and exhaust openings clear of leaves, paper or other foreign matter which may restrict
air flow;
d) Keep the engine clean of dirt, grease and other substances which inhibit heat
dissipation;
e) Use sound judgment in operating the engine. Avoid the two extremes of racing and
lugging.
Advance the throttle only enough to handle the load, yet be certain that the engine
speed is high enough to maintain adequate fan speed for cooling. Run the engine only
when engaged in work operations or when traveling the crane. Avoid prolonged
periods at idle and shut the engine down if operations are interrupted.
SANDY OR DUSTY WORK SITES
The presence of large amounts of sand or dust at the work site can contribute to
accelerated component wear. Either substance will act as an abrasive when deposited on
moving parts of the crane. The problem is combated by more frequent lubrication and by
the servicing of breathers and filters at shorter intervals. Follow the recommendations
below when operating in sand or dust on a regular basis.
a) Keep sand and dust out of the hydraulic system by keeping the reservoir filler cap tight
and servicing the hydraulic system filters frequently;
b) The fuel system should be kept free of sand and dust by keeping the tank filler cap
tight and servicing the fuel filters frequently;
c) The engine breathers and air cleaner should also be serviced frequently to prevent
sand and dust from entering the engine. The engine oil and oil filter should be
changed at shorter than normal intervals to ensure a clean oil supply to the engine’s
moving parts;
d) When lubricating the crane, thoroughly clean each grease fitting before attaching the
grease gun. Pump generous amounts of grease into all lubrication points, using the
fresh grease to pump out the old;
e) Adequate ground bearing support must be provided for the outrigger floats when
operating in sand. Be alert for signs of carrier movement during operations.
The increased frequency of lubrication and service discussed above should be determined
by observations made at the work site. Inspection will determine how long it takes for
lubricants, breathers and filters to accumulate unacceptable amounts of sand or dust. The
frequency of lubrication and service should be adjusted accordingly.
