1. The oil cup at the rotating part of the connecting rod should be filled with lubricating oil (butter) in time, and the bearing should be filled with lubricating oil after working for 50 hours. It is strictly forbidden to run without oil.
2. The gear oil level should be kept between 1/3 and 1/2 of the gearbox height, and the gear oil should be replaced every 3 months or 150 hours of work.
3. A few drops of engine oil should be frequently added to the joints of each operating rod.
4. Inflate the tail wheel in time to maintain pressure. Adjust the belt tension frequently to prevent the belt from being too tight to damage the belt, damaging the bearing and other parts, and to prevent slipping when it is too loose.
5. Rubber wheels should not be in contact with chemicals such as oil to prevent accelerated aging. Store in a dry, dark place.
6. It is strictly forbidden to work on plots with bricks, gravel and tree roots to prevent damage to the cutter.
7. Clean the machine frequently to ensure cleanliness.
8. Non-operating transportation must not drive on hard roads to prevent accelerated wheel wear.
9. Adjustment of the inclination of the cotton picking head

1.By adjusting the length of the boom on both sides of the cotton picking head beam, the front roller is 19 mm lower than the rear roller during machine operation, which makes the ingot picking contact more cotton and allows the residue to flow out from the bottom of the cotton picking head. The length of the boom is the pin-to-pin distance of 584 mm, the two lifting frames should be adjusted in the same way, and the tilt adjustment should be done in the cotton row.

2.Adjustment of the pressure plate gap

The distance between the pressure plate and the tip of the ingot removal can be adjusted by adjusting the nut on the hinge of the pressure plate, about 3~6 mm. Through practice, it should be adjusted to the tip clearance of the pressure plate and the ingot removal is about 1 mm. The assembly will leak cotton, and if the gap is too small, picking the ingot will create a deep groove on the pressure plate and damage the parts. Even the friction between picking the ingot and the pressing plate will produce sparks, which becomes a hidden danger of machine fire.

3.Adjustment of spring tension of pressure plate

This is achieved by adjusting the relative position of the adjusting plate and the round hole on the bracket. From rotating the adjusting plate until the spring just touches the pressure plate, the front cotton picking head continues to rotate and adjust to 3 holes on the adjusting plate, and the rear cotton picking head is adjusted to 4 holes, aligned with the fixed holes on the bracket, insert flange screws, also can be adjusted to 4 front and 4 back. When adjusting, the pressure plate on the back picking head should be adjusted first, and the pressure plate on the front picking head should be tightened only when necessary. If the spring pressure is too small, the picked cotton will have less impurities, but the remaining cotton will increase; if the pressure is too high, the net picking rate will increase, but the cotton impurities will increase, and the wear of the parts will increase.
