** JACKS **
= Provide a level and solid support for the entire jack base area.
= Never place any part of your body under the load. Ensure the load is
on a solid support before venturing under.
= The entire jack saddle must be in contact with the load.
Movement of the load to be in the same direction as jack plunger.
= Remove the jack handle when it is not being used.

** CYLINDERS **
= Provide a solid support for the entire cylinder base area. Use cylinder
base attachment for more stability.
= Do not use cylinder without daddle. This will cause plunger
to "mushroom". Saddles distribute load evenly on the plunger.
= Always protect cylinder threads for use with attachments.
= The entire cylinder saddle must be in contact with the load. Movement
of the cylinder must be parallel with the movement of the load.
= As with jacks, never place any part of your body under the load.
Load must be on cribbing before venturing under.
= Keep hydraulic equipment away from open fire and tempertures
65C(150F)

** PUMPS **
= Don't use handle extenders. Hand pumps should be easy to operate
when used correctly.
= Fill pump only to recommended level. Fill only when connected cylinder
is fully retracted.
= Close release valve finger tight. Using force will ruin the valve.

** HOSES & COUPLERS **
= Clean both coupler parts before connecting. Use dust caps when
coupler parts are not connected.
= Keep hoses away from the area beneath loads.
= Don't lift hydraulic equipment by the hoses.
= Detach cylinder only when fully retracted or use shut-off valves or
safety valves to lock-in cylinder pressure.
= Don't kink hoses. Bending radius should be at least 115millimetres.
Don't drive over or drop heavy objects on hoses.
