2. Try not to use bulk butter. Bulk butter is troublesome to fill, and most of it is exposed outdoors. After filling, it is also stored in a cold iron oil storage barrel with high viscosity.

3. Crawler grease bomb or GRT barrel grease bomb can be used to facilitate heat preservation. When in use, it can be installed in an electric grease gun, the temperature can be maintained for a period of time, and the viscosity decreases slowly when in use.

4. Choose electric grease gun, which has high pressure and high speed, 5- 10 times that of manual grease gun, and can be filled quickly.

5. When the temperature drops in winter, especially after-10, the battery will be weakened by active ions and the storage capacity will be reduced. To avoid this problem, you should charge it indoors; Keep warm when not in use.

6. When not used for a long time, it is very important to leave it for two months and charge the battery once, which can prolong the service life.
