Lubricate release valve
32gr Hydraulic oil
Poor lift performance
*larger capacity ram
used
Pump has no
resistance, lift ram will
not raise to full stroke
Pump has no
resistance, lift ram will
not raise to full stroke
*Pump has no
resistance, lift ram will
not raise to full stroke
Fluid level low
Air trapped in system
*Ram raises to partial
extension only
Drain fluid to correct
level
Lift ram raised for
extended period
causing air ingress to
hydraulic system
*Ram oil capacity
larger than reservoir
capacity
Fill fluid to correct
level the Bleed system
With ram fully
retracted, remove oil
filler plug to let
pressurised air escape
reinstall oil filler plug ,
Bleed system
*Select higher capacity
mated pump and ram
set
