8. 2 STORAGE
Do the steps that follow if you do not use the crane for more than 6 months:
(1) Clean contamination off of the crane.
(2)
Fully retract all the “cylinder pistons”.
(3) Fully extend the outriggers to lift the tires away from the ground. Inflate the tires to
specified pressure and put “wooden wedges” below the tires.
The “wooden wedges” cannot touch the tires.
(4) Remove the battery and keep it in a dry location with good airflow.
Charge it (once every half month) and discharge it (every three months) in regular
intervals.
(5) Fill the fuel tank with oil.
(6) Fill the coolant tank.
(7)
You must lubricate the surfaces of all the “exposed metal” components to prevent
corrosion.
(8) Remove all contamination (dust and sand) from the wire-ropes and lubricate them with
ZG-3 (a calcium based graphite grease).
(9) Keep the crane in a garage. If not, put a water-proof cloth on it to prevent corrosion. In
rainy season areas, examine the crane frequently to prevent corrosion. Protect the
crane from very cold weather conditions.
(10) Operate the engine for 15 to 30 minutes each month. Examine the mechanisms at idle
speed to make sure that they operate correctly.
(11) Make sure that one person keeps the crane prepared for operation.
(12) If you do not operate the crane for more than three months:
Operate the engine at idle speed for one hour in the three month interval.
(13) If you do not operate the crane for more than 18 months:

Keep the crane clean and do the usual maintenance.

Replace aged seal components.

Do a general inspection of the engine to see if you must replace the coolant,
diesel oil, and air / fuel filters.
