Shredder maintenance and precautions
Maintenance of the shredder: The main function of the shredder is to smash paper documents and small non-paper items (such as plastic cards) so that they lose the information carrier. The service life of the shredder is generally 3 to 5 years. In order to ensure the safe and stable operation of the shredder, it should be regularly maintained. The maintenance process of the shredder varies from model to model. The maintenance requirements of the granular shredder are more stringent than those of the strip model, and must be carried out in strict accordance with the procedures described in the manual.
Regular maintenance procedures include cleaning and refueling all components, removing dust, checking the movement of the tool, inspecting electrical components, and adjusting and replacing damaged components.
The paper cutting unit of the shredder is the maintenance focus.
1. Maintenance of shredder cutters
The tool is the most precise part of the shredder. In addition to the requirements for machining accuracy, it also has high requirements for the installation of the tool. Any mechanical misalignment and lack of oil will seriously affect the service life of the tool. The tool should be lubricated regularly and the lubricant used should also comply with the regulations.
In addition to lubricating, the lubricating oil used in the shredder ensures the mechanical parts to work well, as well as the function of softening and removing deposits between the teeth to prevent rust on the surface of the tool. If it is found that there are foreign objects such as metal sheets and dust in the interdental space, it should be cleaned up. The process of lubrication lubrication is very simple. The lubricating oil can be directly dripped on the cutter surface through the paper feed port. After the oil is slightly diffused, the power is turned on, and the machine is reversed for 10~15s, so that the lubricating oil is fully diffused to all parts of the cutter. Finally, Break a few sheets of paper to wipe off excess oil from the tool surface.
Check the movement of the tool. If there is uneven shaft clearance between the two hobs, please consult the professional. If there is no oil or excessive dust in the bearing part of the hob, abnormal noise will occur due to the resistance becoming larger during operation, and the problem can generally be solved after refueling.
2. Maintenance of shredder gears
The main function of the gear is to transmit power. It is usually made of engineering plastics. Although it has a certain mechanical strength, it is a vulnerable part in the shredder. Due to the strong overload capability of the AC motor, when the amount of shredded paper is too large and the paper jam occurs, the torque generated by the motor will cause the gear to break and break the teeth. The maintenance focus is on regularly checking the integrity of the gears, removing dust and other deposits between the teeth, and the lubricant is greased. Always replace the gear that has the problem.
3. Maintenance of shredded paper case
The box is a container for shredded paper scraps, and it is also a support for the whole machine. It is very convenient to move the casters on the ground. Protecting the cabinet is one of the maintenance contents. Avoid placing heavy objects on the shredder, avoid hitting the cabinet with hard objects, and do not use chemical reagents to remove dirt from the surface of the cabinet. The second is to avoid moving the whole machine as quickly as possible. If the caster is found to be running poorly, it should be repaired in time. If it is damaged, it should be replaced in time. The cabinet should be kept dry and tidy.

A good kennel will not endanger the dog's health. After all, for dogs, the kennel is where they sleep, so warmth and comfort are a must. Smaller dogs are mostly sensitive and insecure. Compared with open kennels, semi-enclosed kennels can bring a sense of security to small dogs and help puppies to sleep deeply.
Medium and large dogs have a large body of heat dissipation, so a dog bed is more recommended. The size of medium and large dogs is larger. If you buy a semi-enclosed kennel, you need to buy a larger size. A large kennel takes up more space. If the kennel is too small, it will not help the dog to stretch itself. If the dog`s body is curled up in a small kennel for a long time, the dog can`t sleep well, and it will also have a bad influence on the dog`s physical development. But the dog bed is different, it is open, it is convenient for dogs to stretch their body, sleep more comfortable, and the dog bed has a certain distance from the ground, good heat dissipation, will not be damp, and prevent the dog from developing skin diseases.
