5.2.2 Hand pump operation mode
WARNING!
Risk of squeezing!
When the die system closes, there is a risk of getting squeezed
between the die and the work piece.
• Keep the feed opening for the workpiece as small as possi-
ble.
• Keep a minimum distance of 120 mm (A) to the die system.
The pumps provide for a two-stage flow. Without load, the pump op-
erates in the first stage with a high flow for rapid extension. As soon
as there is load contact, the pump automatically changes to the sec-
ond stage to build up pressure.
As soon as the pump pressure reaches about 280 bar, pumping must
be stopped briefly, and the handle must be lifted to change to the
second stage (high pressure). When the pump has switched, less
power is needed for pumping.
Do not move the handle to the end stop.
