Clean the machine, remove the chaff, broken straw and other attachments on the machine, lubricate all friction parts in time, clean the chain outside and lubricate it with engine oil. Check the technical status of the engine, including whether the oil pressure and temperature are normal, and whether the engine sound and fuel consumption are normal. Check whether the power machine can operate normally. The inspection and adjustment of the header, including the speed and height of the reel, the travel and cutting clearance of the cutter, the clearance between the auger and the bottom, and the speed of the auger, meet the requirements. Small wheat combine harvester. Check and install the fire extinguisher, check whether the fire extinguisher carried is expired, and if the machine is to be carried by itself, it can be fixed on the rack; It can also be carried separately for emergency. Check whether the headlamp and service lamp of World Combine Harvesters manufacturers are normal. The headlamp and service lamp shall be connected to the engine and installed in a reliable position according to the user's needs. Check other items. Whether the welding parts have cracks, whether all kinds of mechanical oil are clean and sufficient, whether the movement of rotating parts is flexible and reliable, whether the control device is flexible, accurate and reliable, whether the walking and parking brake devices are normal, and they must be accurate when used. It is prohibited to operate the machine with defects. Check the fastening of bolts at all parts, and retighten them if they are loose. Then it is coupled with the power. The power must match the size of the machine and cannot be selected at will.

Check all components to ensure that they are in good condition, and the fault shall be eliminated in time. Check the fastening of bolts at all parts, and tighten them if they are loose. Remove the residual grains and sundries after the previous operation, conduct a comprehensive inspection of the machine, and add lubricating oil to the bearing and other rotating parts every shift. Install the grain bag. The machine adopts nylon bag to connect the grain bag. If the grain in the grain bag is too full, the grain will spurt out at the slag outlet, increasing the loss rate; If the grain bags of small wheat combine harvester can be changed frequently, the harvesting efficiency will be affected and the harvesting speed will be reduced.
