3. BEFORE USE
Conduct a thorough visual inspection checking for leaks and any abnormal conditions,
such as cracked welds, and damaged, loose, or missing parts.
Bleeding Air from the System
Air can accumulate in the hydraulic system during the initial setup or after prolonged use,
which can cause the hydraulic ram to respond slowly or operate in an unstable manner or
even leak hydraulic fluid.
To remove the air;
1.
Position the hydraulic ram so that it is at a lower level than the hydraulic pump unit,
with the piston end pointing down (see illustration below).
The objective is to "float the air bubbles up the ram, then up the hose and back into the
hydraulic pump.
2. Close the release valve and pump the handle on the hydraulic pump unit rapidly.
3. Without putting load on the hydraulic system this should quickly extend the ram.
4. When fully extended, open the release valve fully to allow the ram piston to retract.
Air bubbles will then be carried back up to the pump reservoir.
5. Repeat this process 3-4 times.
6. Then with the ram fully retracted, ensure the hydraulic pump unit is positioned
horizontally level.
7. Remove the hydraulic pump units filler screw to release trapped air from the
hydraulic pump unit.
8. Check oil level. If necessary top up the hydraulic pump reservoir with good quality
hydraulic jack oil until the fluid level is within 13mm of the filler screw hole.
Important: Repeated changing of hoses may result in loss of hydraulic oil and/or air
bubbles entering the hydraulic ram unit. This will adversely affect the rams performance
and can cause hydraulic ram fluid leakage as the seals may not be under sufficient
pressure to operate effectively. In this circumstance always "Bleed Air from System" and
"Check Hydraulic Oil Level" to restore normal operation.
