Troubleshooting
Jack will not raise/lift load/lift load to full height
Jack lowers under load
•
The weight of the load is higher than the max. indicated load for the jack. Use a
suitable jack.
•
Release vale is open. Close it tightly by turning it clockwise. Check whether dirt
prevents the release valve to be closed completely. Remove the release valve and
clean it.
•
Inspect oil level and add/replace oil when necessary.
•
Remove air from hydraulic system.
•
If above steps do not solve the problem, there is something wrong with the
hydraulic system itself. Contact your local dealer for service and support.
Jack will not lower
•
When there is load on the jack and it will not lower, remove the load by carefully
lifting it with a second jack.
•
Never apply excessive force (e.g. use a hammer) on the saddle to lower it.
•
Check the oil level – too much oil will block the hydraulic system.
•
Dirt may block the release valve. Remove and clean it and replace the oil.
•
Remove air from hydraulic system.
•
Make sure the system is sufficiently greased.
Weak lifting
•
This is possibly be caused by dirty oil – replace the oil.
•
Close the release valve tightly by turning it clockwise. Check whether dirt prevents
the release valve to be closed completely. Remove the release valve and clean it.
•
Remove air from hydraulic system.
Unloaded saddle slowly moves up
•
Remove air from hydraulic system.
