Hydraulic System Warnings
⚠ DANGER Failure to observe these warnings can result in serious personal injury including, in
rare cases, death.
⚠ WARNING The Hydraulic Hoses and connections must be inspected before any attempt to
raise a Vehicle is made.
⚠ WARNING Double check to verify all Hydraulic Hose connections and fittings, including
unused auxiliary port plugs on the Power Unit, the Flow Divider, the Cylinders and
anywhere else in the Hydraulic System are tightened.
⚠ WARNING The Power Unit is a Hydraulic Pump capable of developing pressures in excess of
5,000 psi (345 BAR). A pressure relief valve is used to set the pressure to the
desired level. Tampering with, adjusting, modifying, or removing the relief valve is
extremely dangerous and is not recommended. Only trained Hydraulics Technicians
should make adjustments to the relief valve, using calibrated Hydraulic Pressure
gauges to assure the proper pressure setting is achieved.
⚠ WARNING Changes to the output pressure may render the power unit incompatible with
pressure limitations of other components in the Hydraulic Circuit. This may cause
catastrophic failure of those components, and could result in property damage,
serious personal injury, or death.
⚠ DANGER The Hydraulic System can contain high pressure which, if suddenly released, can
cause severe injury or death.
⚠ WARNING Do not attempt to connect or disconnect Hydraulic Hoses while the equipment is
loaded or while a Vehicle is on the Lift, or the Hydraulic System is under pressure.
⚠ WARNING Keep bare hands away from Hydraulic Fluid; always wear gloves when handling
Hydraulic Fluid, Cylinders or Hydraulic Hoses.
⚠ WARNING When handling Hydraulic Fluid, always observe the safety instructions from the
manufacturer.
⚠ WARNING Always promptly clean any Hydraulic Fluid spills. If a leak is the source of the spill,
lock out the Lift to prevent use until the Hydraulic System is repaired.
⚠ WARNING Do not attempt to service the Power Unit through the rear panel. Only access the
Power unit through the Front of the Console.
⚠ WARNING If you choose to change the Hydraulic Hose lengths, the two hose lengths must
be within 5% of each other
. The SP-7XE/F Lift is a Hydraulically Balanced Lift. If
the hose lengths vary by more than 5% there is a risk that the Platforms will rise
unevenly. Choose a certified Hydraulic Hose fabrication facility to assemble any
replacement hoses.
