1. The pump needs to check the oil regularly. Once it is short of oil, it will pull the cylinder to strike.
2. The motor of the vacuum cleaner needs to check the carbon brush regularly. If the carbon brush is burned, it will strike. What needs to be reminded here is that you need to know a little electrician to disassemble the machine. Otherwise, it will be a waste of repair.
3. Common tools such as towels, brushes, buckets, etc. must be counted frequently, otherwise problems such as missing and fragile (rotten) will often occur, and decimals are not often counted.
4. The amount and deployment of products and consumables are very important. If you don't use it, if you don't use it, it will cost the boss one more point.
5. Pay attention to the management of workers' work clothes, which are also bought with money.
