TECHNICAL MAINTENANCE
Regular technical maintenance can help avoid the early abrasion of motion parts, reduce the accident frequency when
the vehicle is used and stop some potential accidents, so it is a key point to improving the efficiency and prolong its ser鄄
vice life. The details are:
1. The new vehicle should be loaded in strict compliance with the rules in its running-in period;
2. Everyday before and after you drive your vehicle:
荫
Inspect the hydraulic oil amount and add more if the oil is inadequate; inspect whether hydraulic system is damaged
or leak, and repair it if so:
荫
Inspect whether such parts as the top and bottom bolster of the hydraulic cylinder and connecting rod are connected
and fixed. Observe whether all the motion parts and their neighboring fixed parts are damaged or deformed;
荫
Inspect the condition of the carriage, second frame and spare wheel frame and observe with special attention
whether the weld joints are open or cracked; inspect the work or abrasion conditions of gear pump, power take-off and
hydraulic cylinder, maintain and repair or replace the damaged parts.
3. Every week or after 50 working hours:
荫
Inspect all the gas lines and hydraulic tie-ins leak, if so, replace the damaged hoses;
荫
Inspect all the bolts and nuts to see whether they are loose, if so, fasten them;
荫
Inspect all kinds of velvets and hydraulic cylinder, and clean them if they are dirty;
荫
Inject oil to all the injection locations once to ensure the vehicle can work normally;
荫
Inspect the conditions of stow-wood, rubber cushion blocks and rubber cushion belts, and replace them in time if

deposits be cleared; hydraulic oil must deposit 48 hours before injected into oil tank; the filtration accuracy of hydraulic
oil should be lesser than 25滋m.(The oil tank must be cleaned once each week or after 50 hours; the hydraulic oil should
be changed once when the carriages have been lifted 600-800 times, and must be changed any time when the oil is
dirty or aged; the longest period is one year.)
