Maintenance
Starting Recommendations
Check the air cleaner daily before starting the machine. If you operate the machine in heavy snow,
attach a burlap sack loosely to the pre-cleaner. Keep the burlap sack away from heated parts.
In order to assist in warm-up, block the radiator. Blocking the radiator will restrict air from the fan.
Before entering the operators cab, inspect the condition of the following parts: hydraulic hoses, tires,
and fan drive belts. Inspect for cuts, cracks and worn spots and connections. Running the engine at
idle will keep the engine compartment warm. The compartment for the transmission will also be kept
warm. However, running the engine will not keep the hydraulic system warm.
The outer wrapper on hydraulic hoses can crack when flexing occurs at cold temperatures. This does
not mean the hoses have failed. The hoses will still carry oil under pressure.
Normal machine operation will condition the hoses if arctic fluids have been installed in your crane.
However, the arctic fluids must be put into the system before the cold weather begins.
Check the machine in order to be sure that the voltage of the battery heater blanket, engine coolant
heater and engine block heater matches the power source. (See list in Cold Weather Package
Specifications on page 216 .
To avoid valve damage, always run the engine until the coolant temperature is at least 82°C (180°F).
After the engine is warm, proceed with warming up the other systems. Start with the hydraulics. Run
the engine at less than 1/3 throttle, and slowly move the boom hoist joystick control to lift the
attachment in sequence of raising, lowering, extending and retracting the boom. Extend the travel of
the cylinders during each cycle. Perform this operation for all hydraulic circuits such as winch raise/
lower, swing left/right, outrigger raise/ lower jack cylinders, beams extend/retract.
Exercise the transmission and power train. Engage the parking brake or apply the brake. Run the
engine slightly above LOW IDLE. Alternate shifting the transmission from forward to reverse. Repeat
several times-1st gear forward low to 1st gear reverse low to 1st gear forward low.
Release the brake. Move the crane forward and backward for several meters (feet). Continue this
method for several minutes.
Only operate the crane under light loads until the systems reach normal operating temperatures.
Block the radiator to decrease the warm up time of the engine and compartment area . If temperatures
are extremely cold, use a canvas over the engine compartment and a space heater. This will aid in
starting the engine. Use of a canvas over the hydraulic components will improve initial warming of the
components.
Parking Recommendations
Always park the crane in the proper area. Park the machine on wooden planks. The planks will keep
the tires from freezing to the ground.
