Lowering
Raise the load enough to carefully remove the jack stands.
Insert handle onto release valve and slowly turn the handle counter-clockwise, but not more
than half a turn. If load fails to lower, carefully transfer the load to another lifting device and
jack stands. Carefully remove the affected jack, then the jack stands. Lower the load again by
slowly turning the release valve no more than half a turn.
Caution: Be sure all tools and personnel are clear before lowering the load. Danger-
ous dynamic shock loads are created by quickly opening and closing the release
valve while the load is being lowered. The resulting overload may cause hydraulic
system failure which could cause severe personal injury and/ or property dam-
age.
After removing the jack from under the load, push the ram and handle sleeve down to reduce
exposure to rust and contamination.
Maintenance
Important: Use only a good grade hydraulic oil. Avoid mixing different types of fluid and never use
brake fluid, turbine oil, transmission fluid, motor oil or glycerine.
Adding oil
With the ram saddle fully lowered and pump piston fully depressed, set jack in its upright level
position and remove the oil filler plug.
Fill until oil is level with the filler plug hole and reinstall the oil filler plug
Changing oil
For best performance and longest life, replace the complete fluid supply at least once a year.
With the ram saddle fully lowered and pump piston fully depressed remove the oil filler plug.
Lay the jack on its side and drain the fluid into a suitable container.
Note: Dispose hydraulic fluid environmentally friendly in accordance with local regula-
tions.
Refill with good quality jack oil. Reinstall oil filler plug. We recommend MOBIL DTE 13 or equi-
valent.
Lubrication
A coating of light lubricating oil to pivot points, axles and hinges will help prevent rust and as -
sure that wheels, casters and pump assemblies move freely.
Periodically check the pump piston and ram for signs of rust or corrosion. Clean as needed
and wipe with an oily cloth.
Caution: Never use sandpaper or abrasive material on these surfaces.
When not in use, store the jack with pump piston and ram fully retracted.
