Small mixer, mixer transmission requirements and precautions 1, before the new compact mixer started, first check the entire hydraulic system and remove dust and debris, and check the entire connection is correct and whether the other problems.   2,3 square mixer DTE26 Mobil hydraulic oil tank are installed (to oil above the standard scale, pump housing and motor housing should be oil filled.   3, start the engine, steering servo cylinder handle make mix at low speed forward and observe the hydraulic system is working properly.   4, the oil temperature must not exceed 60 ° C, the pump casing pressure must be less than 0.25MPa.   5,4 square mixer note on the fan hot concrete mixer truck-9 m3 sink in the 50 ° C-70 ° C range should be in operation. Fan failure is not running, it should be repaired.   6, charge pump relief valve, low pressure relief valves, high-pressure relief valve factory set-pressure, can not be altered arbitrarily.   7, the oil in the components and piping must not have leakage, such as leakage occurs, should be repaired.   8, when the operation state of the work, not free repairs and adjustments.   9. The mixer hydraulic pump, motor if a failure occurs, the need for timely replacement down to send professional maintenance department repair specified in removing the old pumps, motors installed new pumps, motors should note the following:     1) Remove the old pump, the motor, the tubing should be removed, requiring each oil pump and tubing on the interface immediately sealed to prevent dust from entering the pump and pipeline, and then removed from the mixer pump.     2) mounted on the stationary pumps, motors. Note: The screws tightened, sealing the pump, motor, oil port, takes over.     3) When all tubing installation, spin off oil dasion concrete mixer truck 10cbm pump R port plug, put in the best pump air until the smoke does not contain within R port oil gas and then tighten the R port oil plug.     4) Remove the motor from the uppermost T port connector into the motor was added until clean hydraulic oil to fill the pipe and then tighten the joint.     5) Check the oil level in the tank, if not to a level above the intermediate position, shall be added to the cleaning of the hydraulic oil in place.     6) starting the engine when idling for 10 minutes (control box two handle all in the middle position, the mixing tube does not move), check the oil pump, the motor noise situation as well as the pipeline if there is leakage.     7) Slow joystick, one direction at a slower mixing tube feeding direction of rotation 20 minutes (stirring barrel without material, the car idling out);   8) Move the lever back to the middle position, so that the mixing tube stop, check the oil tank, fuel to the median.   10. The hydraulic oil usage instructions:     Cooler must be cleaned and replacement filter elements and hydraulic oil (1) the first phase of a new vehicle and the mixing tube accumulated over 300 hours.     (2) after six months or after every 500 hours to replace the filter and hydraulic oil.     (3) Hydraulic oil must be imported or domestically produced high-quality hydraulic oil, and after 10 micron precision filter to join the tank. We recommend using MOBIL (Mobil) DTE26, SHELL (Shell) TELLUS68, BP (British Petroleum) SHF68, CASTROL AWH68 or 68 with the same level of hydraulic oil, lubricating oil can not be replaced with another.     (4) different brands of hydraulic oil can not concrete mixer truck dimensions be mixed, the tank must first put all the original hydraulic oil after replacement of the hydraulic oil to add new hydraulic oil.     (5) hydraulic oil viscosity: It uses low viscosity oil should be used MOBIL (Mobil) DTE15 when the ambient temperature remains below 15 ° C in, SHELL (Shell) TELLUS46, BP (British Petroleum) SHF46, CASTROL AWH46 or equivalent oil. Mixer truck parked overnight, even if the climate warmer, the oil temperature will be reduced, therefore, first the engine idling at a warmer climate turned five minutes, ten minutes colder climate idle after operational.
