1. The function and adjustment method of each device of the double tea picking machine 1. The blade is composed of two upper and lower blades, and the reciprocating motion of the blade cuts off the portion where the tea leaves are clamped. 2. Both the handlebars of the main unit and the auxiliary handpiece are equipped with anti-vibration rubber. 3. Adjustment of sliding nut: used to adjust the expansion and contraction of the handle of the auxiliary hand. Turn the nut counterclockwise for about 1/4 turn, and adjust the handle to the position where it is easy to work. After adjusting, be sure to lock the slide nut clockwise. Due to the fast eccentric locking device, the total movement of the sliding nut does not exceed 1/2 turn after the handle is inserted, but please do not rotate too much to avoid damage to the thread. 4. Adjustment of the operation switch: It is used for the angle adjustment of the handle of the main hand table and the auxiliary hand and the sliding adjustment of the handle of the main hand table. Pull the operation switch mounted on the handle to the loose direction, adjust it to the position suitable for the working position, and then pull it toward the lock direction. 5. Operation of dual-purpose switch: It is mounted on the handle of the main hand table. The upper switch is the tension pull switch to control the movement and stop of the blade. The lower switch is the throttle switch to control the speed of the gasoline engine. 6. Gasoline engine switch. (1) The stop switch on the gasoline engine side is a push button switch, and the gasoline engine is completely stopped during operation. (2) Turn the stop switch of the main unit to the “OFF†side, and the gasoline engine stops. Even if you want to start the launcher, it won't start. Second, the operation method and essentials 1. Start and stop the gasoline engine. (1) Press the hand oil pump several times before starting, the fuel flows into the carburetor, the air is discharged, and the throttle is opened 1/3-1/2. (2) Set the circuit switch to the "ON" side and close the choke properly. (3) Press and hold the gasoline engine, first gently pull the starting rope out a small amount, and feel the heavy feeling on the hand, then quickly pull the starting rope. When pulling, the person needs to stand on the side away from the cutting edge. (4) After starting, fully open the choke, then increase the throttle and put it into normal operation. (5) When parking, first set the throttle switch to the low speed position, then set the circuit switch to the “OFF†side to stop the gasoline engine from rotating. 2. Picking methods and essentials. (1) Place the handle in an easy-to-operate position. (2) Install the leaf bag on the machine and tighten the bag to prevent the tea leaves from spilling. The leaf bag is firmly smashed into the bag hooks of the machine, and the net cover is moved from the center of the machine to the side of the gasoline engine. (3) Remove the blade cover. (4) At the time of fuel replenishment, simultaneously lubricate the blade to avoid wear of the blade. (5) Start the gasoline engine in the order of starting the gasoline engine. (6) When the machine is operated, the workers of the main hand table and the auxiliary hand handles are supported by both hands. (7) Slowly set the throttle switch in the dual-purpose switch to the “ON†side to speed up the gasoline engine speed, and then turn the tension pull switch to the entering direction to drive the blade to reciprocate. (8) Adjust the speed of the gasoline engine according to the operator's speed, cut mark and leaf collecting condition, and fully open (high speed) operation in the case of wet leaves. (9) The tea field is picked side by side, and the side of the gasoline engine is slightly slower, which is conducive to smooth operation. Third, maintenance points 1. Blade cleaning: After work, dry the mud and grass attached to the blade, inject the lubricant, and put on the knife cover. 2. Adjustment of the blade gap: excessive blade clearance results in low pruning ability, and too small will increase frictional resistance. 3. Maintenance of each part: overhaul each part and adjust as needed. 4. When not in use for a long time, follow the following methods: (1) The defective part should be repaired. (2) When the machine needs to be stored for a long time, after the gasoline engine is cooled, the fuel is poured out, and then the filter in the fuel tank is pulled out. The hand oil pump is pressed several times to let the residual fuel in the pipe flow back to the fuel tank, and finally all the fuel in the fuel tank is sucked out. (3) Remove the spark plug, drop a few drops of oil in the hole, gently pull the starter, apply the oil to the cylinder, and install the spark plug. (4) Wipe off the external dirt and place it in a dry and safe place. (5) Perform pre-operation inspection and periodic inspection in a flat and safe place before use. Remember, in order to prevent the gasoline engine from starting suddenly, it is necessary to remove the spark plug cap after the gasoline engine is stopped and cooled. In the inspection items, the necessary inspection, repair, adjustment, and replacement should be entrusted to the store. Fourth, matters needing attention 1. Gasoline engine use precautions: (1) Always check the fixing screws and nuts of each component for looseness. (2) All fuels must use a blend of No. 90 motor gasoline and two-stroke special engine oil (JASOFB grade). In order to extend the life of the gasoline engine, the mixing of gasoline and oil must be correct, using a volume ratio of 25:1 (the ratio of gasoline to oil should be 20:1 for the first two days of the new machine). Deteriorated fuel and incorrect ratio fuel are prohibited. Otherwise, normal operation cannot be guaranteed. (3) The gasoline engine cannot stop suddenly at high speed to prevent damage to the machine. (4) Do not touch the spark plug while the gasoline engine is running. (5) The following points should be achieved when filling the gasoline engine: 1 The gasoline engine is stopped and cooled before refilling. 2 Fill the oil in a well-ventilated place or outdoors. 3 Wipe the area around the fuel tank to prevent foreign matter from entering. 4 When opening the fuel tank cap, it should be slow to prevent the fuel from leaking out. 5 The fuel overflows, use the cloth to dry, do not let the oil overflow when filling the oil. 6 Fuel should be added to about 80% of the fuel tank. 7 Close the fuel tank cap. 8 After oiling, it should be at a distance 2. Precautions during operation. (1) When the direction is changed and the operation is interrupted, confirm that the dual-purpose switch returns to the fully closed side, and the blade is completely stopped before switching. (2) When the operation is interrupted or terminated, the gasoline engine must be stopped and the knife cover installed. (3) When the blade is in an abnormal vibration sound such as biting a branch or the like, return the throttle switch to the low speed position, and set the gasoline engine switch to the "OFF" side. After confirming that the gasoline engine is stopped, move it to a safe place for inspection. . If there is any abnormality, it should be suspended and commissioned by the store to overhaul. If you exclude foreign objects in the operation of the gasoline engine, it is very dangerous! (4) When the operation is finished, the gasoline engine must be stopped. (5) When covering the tarpaulin, first check if the gasoline engine is cool. (6) When transporting, please fix the gasoline engine to avoid falling off. 3. Daily considerations: (1) The blade is sharp, especially the running blade, which cannot be touched and confronted by hand. (2) It is strictly forbidden to dismantle and repair people who do not understand repairs. (3) If abnormality is found during maintenance, please repair it before use.
