Linear Vibration Welder 4000 Series, Model VWA User's Manual

Hydraulic Safety

The hydraulic system is self-contained. It normally
operates at between 1,000 and 1,200 psi. It is however
capable of operating up to 1,500 psi. It is unsafe to at-
tempt to bypass the interlocks and operate the welder
with the rear service doors open. The interlocks are
located at the top of the electrical and both hydraulic
service doors. Figure 2-9 shows a door interlock device
and the mating receptacle in the cabinet.
The vibration welder may be shipped with the hydraulic
fluid reservoir full or drained, depending on whether the
destination is local or international. Before operating the
welder, hydraulic fluid must be added to the reservoir if
it is empty. This is covered in Section 3 – Installation,

Hydraulic Drive.
