Hydraulic System ◆ If the crane is operated for a long time with the hydraulic oil at a high temperature, the oil will rapidly deteriorate, shortening the life of the hydraulic components. Take enough care of oil temperature. ◆ The hydraulic oil is more viscous when its temperature is low. If, in cold weather, the crane is operated with a heavy load at high speed without allowing it to warm up, the hydraulic components could be damaged. When the ambient temperature is low, do not start crane operation right away. Instead, let the crane warm up sufficiently; until the oil temperature rises to approximately 68°F 〔 20°C〕 〕. ◆ Be sure to handle the hydraulic pipes carefully. Handling these pipes incorrectly can cause oil leaks
WARNING The hydraulic oil and hydraulic equipment become very hot immediately after an operation. Let them cool down before starting maintenance work. Even when the engine is not running, some hydraulic components remain under high pressure. Careless dismounting or disassembling will cause serious accidents to the human body. Do not attempt to dismount or disassemble hydraulic components, pipings and couplings. [NOTICE] ◆ Using different brands of hydraulic oil together can change the properties of the oil and have an adverse effect on the machine. When hydraulic oil is added, be sure to use the brand that is in the machine. If a different brand of oil must be used, be sure to take out all the remaining hydraulic oil before adding the new oil.
or the hydraulic components to malfunction. Whenever a pipe has to be removed, be sure to consult the nearest TADANO distributor or dealer. ◆ Dust, foreign matter, water, etc. in the hydraulic oil tank or pipes could cause a machine failure. Keep these parts free of dust when working on them.
