Erect the jack is only suitable for use, can not be offset or to use, operating temperature is to 40 ° c ~ 45 ° c, forbidden to acid and alkali and corrosive gas.
Someone asks what is the safety valve for?
Safety valve is used to lock the hydraulic pressure, prevent the use of overload, in order to work in the safety of!!!Just like the seat belt in the car, you can drive without it, but the seat belt plays an indispensable role in the accident!
Specific operations:
lifting
1. Turn the jack oil valve clockwise with the handle (to the tightness).
