The vehicle have distinction installed nagative pressure (cement adsorption)and position pressure (take away)two sets of system,in the process of cement adsorption in order to protect equipment normal using and operator safety,please strict requestion operation as follow:

1、Open power remover

After starts the vehicles,which keep the engine idle speed (600-800r/min),then footswitch clutch and open the most left electromagnetic switch of cab,then slowly loosen footboard of clutch,air blower begin work.Engine rev can adjusted through speeder pistol grip control.

Note:

　　⑴ When the work of negative pressure, please make sure that all close of charging box cover , inlet valve, vane type shutter and outlet valve;

　　⑵ The power remover system do not peg stall!!!

2、Pipe alley valve control

The first step: When the work of suction aggregate (negative pressure),it is must make sure air blower and gas check of body pipeline are both open[See the chart:valve1];

The second step: Close two inlet valve of (positive pressure) air compressor inlet pipeline connect with (forward and backward silo)[see the chart:valve4 and valve5]

The third step: Close the two vane type shutter of (forward backward silo )take away pipeline.[See the chart: vane type shutter 6 and vane type shutter 7 ], so that prevent to damage air compressor system equipment.

3、Suction aggregate control

Make sure that start work of air blower, whose operator can control the speed of suction aggregate reference two set of vane type shutter are installed the top of backward silo and rear part of vehicle.[See the chart 1 and chart 2]

4、Close suction aggregate system

When the silo have fulled,please close the system as follow:

The first step : Footswitch clutch , close the most left electromagnetic switch of the cab,then slowly loosen footboard of clutch and close power remover;

The second step : Close the ball clack 1 and vane type shutter 3 of suction

aggregate pipeline;[See left chart and see right chart ]

The third step :Open the two inlet valve of positive pressure system[See the chart:valve 4 and valve 5 ],so prepare take away.

5、Items to specially noted

　　A. We suggest that gear oil in the air blower need to change each month and apply model GL-5(85W/90)

　　B. In order to protect safety of equipment and driver in an all-roumd way, our company have installed safety equipment in the design process, but we suggest that operator must understand and familiar working instruction, so that guarantee vehicle and vehicular equipment working efficiently.

　　C. Check and maintenance filtering apparatus each week;

　　D. Rubber pipe are installed in negative pressure pipeline is that check and maintanence before each using.

　　E. When the work of suction aggregate system,the negative pressure strict control within the 0.01, otherwise, the body will serious damage or deformation (we suggest that do not full close the vane type shutter of vehicle rear parts)
