TROUBLESHOOTING
• If the jack fails to lift, or fades under the load, first check that the release valve (4) is
closed. Engage the notches at the end of the jack handle (54) onto the release
valve (4) and turn clockwise. Check to see if this has solved the problem.
• Next check to see if there are any leaks in the air system. Examine all connections
and valves to see if there is a leak. If so, have a qualified service technician repair
the connection or replace the faulty part.
• Check to see if there are any leaks in the hydraulic system. Leaks will produce
visible hydraulic fluid at the separation. If there are any leaks, have a qualified repair
technician tighten, repair or replace any leaking components.
• Air in the hydraulic system will cause the jack to fade. If no leaks are detected, bleed
the hydraulic system to remove any trapped air. Bleeding instructions are given on
page 9 of this manual.
• If none of these troubleshooting options solves the problem, it is possible that the
seals of the jack have been damaged by overloading, dirt on the ram or other
environmental factors. Have a qualified service technician inspect the jack for fault
and possible repair.
