100 Tonne Jacks Only
The 100T jack is fitted with an additional low-pressure pump
intended for faster movement of the ram under no load (i.e.
to close daylight). The low-pressure quadrant is on the right
hand side of the jack as shown in Figure 14 and operates in
the same manner as the high-pressure pump.

High and Low-Pressure Pumps
Insert the operating lever in to the low-pressure pump and
raise the ram until the ram head is in contact with the item to
be lifted. Then, remove the operating lever from the low-
pressure pump and insert it in to the high-pressure pump in
order to lift the load.
Important:
The jack will not lift the rated load unless the
high-pressure pump is being used.
