Troubleshooting
Jack will not raise/lift load/lift load to full height
Jack lowers under load
The weight of the load is higher than 2 Ton. 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 spring that pulls the lifting arm down. Replace when broken or re-attach when
loose.
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.
