According to current legislation, no hydraulic jack needs a test certificate. Broadly speaking, if a lifting device hoists from above then the Health and Safety at Work Executive Test Certificate is required. If it lifts from below, then such a certificate is not required by law. Please be aware that it is within the rights of insurance companies to insist that a test certificate is provided for any product they so choose. This is quite distinct from what is required by law. Any customer requiring a test certificate for a jack in order to satisfy their insurance company can obtain such a certificate by having the product tested by any authorised lifting gear testing station. These companies can be found by searching "Lifting Gear" in a directory or on-line.
Is Your Hydraulic Jack Malfunctioning?
First, check that the handle is correctly located into the jack socket. In some cases you can remove the screw pin and check if there are any marks on the handle near the slot. If the material is scored, then you can be sure the handle was incorrectly located and this could cause the jack to drop slowly. Correct instructions for locating the handle are shown on the handle itself. The pin must be located in the slot.
Test For Air In The System
With all hydraulic jacks test for air in the system, or dirt on the valve seat by opening the valve and pumping the hydraulic mechanism 10 or 20 times with the valve open. This will flush oil over the valve seat and purge air from the system at the same time. Very often this is all that is required.
How To Bleed Your Jack
Structural damage to a jack very rarely occurs and when it does it is generally due to movement of load or unsafe location of saddle or wheels. In these cases, the customer's insurance company should be notified in writing immediately. Please be aware that accidental damage cannot be considered as a warranty matter.
