rity will go into the tank and cause damage to the hydraulic components. Do not fill the tank with the mixture of different
brands and types of hydraulic oil or the oil which is on the instructions.
7. Always check the engagement condition of power take-off and gear pump to avoid the accidental lifting of the car鄄
riage caused by incomplete separation of the gears. Besides, pay attention to the unusual phenomena such as the ab鄄
normal voice and overheat under the working condition in order to expel them in time. Or they will cause earlier damage
to the power take-off, gear pump, valves and other parts.
8. Always pay attention to the condition of the hydraulic cylinder and other parts when lifting. There should not be phe鄄
nomena like binding, sliding, jumping or abnormal sounds. These abnormal phenomena should be fixed in time to avoid
the earlier damage to the oil tank.
9. Always check whether the locking structure of the back carriage is in good condition, and make sure it is in the right
angel capable of automatic open and close to avoid the trouble or accidents caused by the accidental open of the back
carriage or when it doesn't open during lifting. When dumping large rocks, heavy lumps or other similar objects, remove
the back carriage to avoid damage to it.
10. During maintenance, pay attention to the working planes of the hydraulic cylinder and the gear pump to see whether
there are bruises and scores, because they will damage the function of the hydraulic cylinder.
11. Pay attention to the solitariness in maintenance, in case that the impurity such as silt and thread residue will infiltrate
into the hydraulic system to pull the components and block the valves and finally damage the working function.
12. If the tipper has not been used for a long time, it must be inspected following the inspection contents for the new
one and then can be reused.

13. You should inspect the conditions of such parts as the carriage, second frame and spare wheel frame, and deal with
such problems as loosening and sealing off to avoid serious accidents.
14. You should examine whether the main frame and second frame are connected firmly, whether U wire and iron are
loose, whether the punch is padded, the cushion and rubber cushion block are fixed, and if they are loose or in version,
you must fasten them and put them the right place and cannot transport goods and unload them, for the frame, the sec鄄
ondary frame and lift system will be deformed or damaged, the tipper will even be turned over, which will threaten safety
of life and property.
15. Loading, transportation and unloading
荫
The goods should be distributed evenly and can not run over the carriage itself, and their density should not be over
1600Kg/m3 with their rest angle be smaller than 45 centigrade;
荫
The fully loaded vehicle should be driven at an appropriate speed according to road condition. When it is inclined in
bad road, it can only be moved on the condition that the goods have been discharged. They can be taken out by manu鄄
al labor from the carriage (if the carriage is mobile, they can be taken out from the side door) and cannot be taken out
by lifting system.
16. Important suggestion: in any of the following conditions, the vehicle will possibly be damaged and accident will take
place. Please pay special attention to them and do not operate in the situations A~I (altogether 9 kinds).

荫
make the vehicle out of control, front wheels off ground and the tipper turn
