pallet jack Exhaust air is very simple to make work to introduce you to

Manual handling car generally have three stalls 

1 is positioned intermediate liftstar semi electric stacker‍ gear, this gear the car is neither rise nor fall. 

2 Dial up is neutral, that is, the decline stalls pallet jack‍, relief position. 

3 down dial is hanging file is closed hydraulic seals can be allowed to rise. 

We just need to gear up the dial hanging files, then press play the same pressure as usual a few handles. At this time, although the vehicle does not increase, but can effectively exclude air inside the pump body. Semi Electric Stackers‍ After about 10-20 times the pressure, the air can be drained. Let rise faster and more powerful!
