General safety guidelines
- Obtain 'Service Manual' on your carrier machine from the manufacturer. Study
and follow all safety recommendations. If there are discrepancies
between our guidelines and those of the manufacturer, the manufacturers safety
instructions must take precedence. This is especially important as regards
welding procedures.
- Always wear safety glasses and protective clothing when installing or adjusting hydraulic components.
- Disconnect the battery cables before any electrical circuit is added or modified.
- Bleed pressure from the hydraulic tank before loosening any hydraulic connection during installation.
- Before welding, disconnect battery cables, and cover all cylinder rods and other vulnerable components with wet rags.
- Always ground the welding lead in such a way that current cannot arc across bearings or other main components.
- Due to the nature of oil under high-pressure, it is necessary to use a piece of cardboard to check for possible leaks in the circuit.

No pressure building up?
It is necessary to understand that the pump only creates flow and that, resistance to flow develops pressure. So, if the pressure and return lines are tied together and a gauge is installed in the line, the gauge would read zero.
There are many different reasons for pressure not building up.
As a preliminary check, a couple of things can be checked.
- Check oil level in hydraulic reservoir.
- Check to see if 'Safety lock' is engaged.
- Check settings on port reliefs or in-line reliefs if any.
- Check shut-off valves.
