There are many types of jacks, and the methods used by different jacks are different. What about the use of ultra-thin jacks? The red light mechanical vertical jack will share the use of some jacks for everyone. These jacks are used in cars and other zero hours.
1. After the jack raises the top of the weight, the support should be used to support the heavy objects in time. Do not use the jack as a support, resulting in damage to the jack or accidents.
2. When using, first connect the quick connector of the manual pump to the top, then select the position and screw the oil drain screw on the oil pump to work.
