Tips and hints for your business
During shipping, a jack can be tipped causing air to get in to the cylinders. For this reason, when you first take a new jack out of the box, it is essential that all of the air is bled out of the jack before use.
In addition, you should follow this procedure on a monthly basis or when you see any laps in lifting power. Bleeding the jack on a monthly basis will help keep your jack working at peak performance.
How to Bleed Standard Service and Bottle Jacks
|
1. Pump 10 times with valve open
|
 |
|
2. Close valve and raise to fully extended height
3. While in full extension, continue to pump 10 times
|
|
|
4. Release the valve and lower cylinder
5. Repeat two times to remove all air from the cylinder if necessary
|
|
|
* Most often this will bleed the jack entirely. If not, after the cylinder has been released and lowered, gently pull the oil fill plug on the side to help release any trapped air.
