By analyzing the energy efficiency characteristics of electric gourds below 10T, it can be seen that only when the load is more than half -loaded, the electric gourd will have high energy efficiency. For this reason, under the premise of ensuring safety, electric gourd should be used reasonably according to the common conditions of the working conditions to avoid excessive electrical gourds selected, so that they are often in a light load when they work, causing energy waste. During use, try to avoid frequent moving. At the same time, keep the electric gourd parts dry. When manipulating, you need to drive the gourd away from the humid area, high temperature area or chemical area to maintain its skills. The maintenance of the electric gourd chain, the chain needs to be lubricated by the machine oil, the high dust factory needs to use the oil, and the foreign objects in the chain and the extreme guideline group should be removed on schedule to ensure the smooth operation of the chain. (Note: Forging factories chain, it cannot be used for oil, because the dust is worn out of the chain. When the electric gourd is not used for a long time, it should be rust-proof and clean, and operates 1-3 minutes to maintain its function. The chain is like the chain. Make a Kazaka sound in use. You can use a little oil to eliminate the sound. When the sound is eliminated, you must not add motor oil. Check the lubricating oil on a schedule, and the shortcomings are refueling.
