Adding Hydraulic Fluid
The Hydraulic Fluid reservoir on the Power Unit must be filled with approved fluid before you begin
normal operation of the Lift.
When you receive the Lift, the fluid reservoir is empty.
The
Power Unit will not work correctly until it is filled with approved Hydraulic Fluid.
The Reservoir holds approximately 3.6 gallons / 13.5 liters. Use care to keep the fluid clean when
filling the reservoir.
Approved fluids are any general purpose ISO-32, ISO-46, or ISO-68 hydraulic fluid, approved
automatic transmission fluids such as Dexron III, Dexron VI, Mercon V, Mercon LV, or any synthetic
multi-Vehicle automatic transmission fluid.
WARNING Do not run your Power Unit without Hydraulic Fluid; you will damage it.
