II. Precautions
1. Precautions on the use of equipment
①Because the surface temperature of the working devices and pipes of the asphalt sprayer during the working
process (including spraying, heating, and filling asphalt and so on) is very high, please wear work clothes,
heat-resistant gloves and protective caps before work to avoid scald.
②Only add asphalt that does not exceed 60% of the rated capacity before first use of the asphalt sprayer.
③Before filling high-temperature hot asphalt (including hot asphalt, SBS modified asphalt and other
high-temperature asphalt) to the asphalt tank, the water in the asphalt tank must be removed completely,
otherwise the cold water will vaporize and expand sharply if in touch with high temperature hot asphalt,
causing risk.
④After using emulsified asphalt and converting it to use high temperature hot asphalt (including hot asphalt,
SBS modified asphalt and other high temperature asphalt), all the emulsified asphalt in the tank and
pipeline must be removed completely, or the moisture in the emulsified asphalt will vaporize and expand
sharply if in touch with high temperature hot asphalt, causing risk.
⑤When converting to the emulsified asphalt after just using the high-temperature hot asphalt (including hot
asphalt, SBS modified asphalt and other high-temperature asphalt) or converting to the high-temperature hot
asphalt (including hot asphalt, SBS modified asphalt and other high-temperature asphalt) after just using the
emulsified asphalt, the remaining asphalt in the asphalt pump, asphalt pipeline, asphalt spray rod, asphalt
nozzle and asphalt tank must be removed completely, or water will vaporize and expand sharply if in touch
with high temperature hot asphalt, causing risk.
⑥During the transportation and spraying processes of the asphalt sprayer, do not stand on the rear working
platform of the truck.
⑦After filling high-temperature hot asphalt, for your safety, non-operators must stay away from the asphalt
sprayer more than 5 meters.
⑧In order to obtain a satisfactory spray quality, the temperature of the asphalt added has the following
requirements: for the common heavy-duty road, the hot asphalt spray temperature is above 160°C; SBS,
SBR and other modified hot asphalt spray temperature is above 185°C; SBS, SBR and other improved
emulsified asphalt (including emulsified asphalt) is between 65-85°C.
⑨In order to ensure the normal use of equipment, the allowable temperature of the heat transfer oil is ≤
250 °C.
⑩When asphalt tanks are filled with emulsified asphalt, sediments at the bottom of large storage tanks must
not be added to the asphalt sprayer, otherwise the truck will not work.
⑪When the asphalt pump sticks, it must not be forced to start. It must be heated to make the asphalt melt
and loose before it can work.
⑫When the power take-off is engaged or disengaged (that is, the power takeoff starts to work), the chassis
pressure must be more than 6 kg (greater than or equal to 0.6 MPa) to step down the automobile
clutch (it is best to turn off the car), otherwise the power take-off and the car transmission will be
damaged.
⑬During the transportation of the asphalt sprayer, the power take-off must be disengaged and the master gas
valve of the gas source must be closed, and the burner must not be used while the truck is traveling.
⑭The reduction gear is engaged at the high-speed position (that is, the gear ratio is 1:1 without deceleration),
