c) Bleed the progressive distributor (3):
Bleeding with additional filling nipple:
If available, screw the filling nipple (Order no. 752.502-91) into the open
thread and fill, by using a hand or filling pump, the distributor with
lubricant until it comes out free of air from all outlets of the progressive
distributor. Then remove the filling nipple and remount the pressure
control valve or lock screw (1).
Bleeding without additional filling nipple:
Screw the pressure control valve or lock screw (1) in. Then switch the
pump on until the lubricant comes out free of air from all outlets of the
progressive distributor (3).
d) Connecting lube lines
The lube point lines must be clean and free of any obstruction.
Connect the outlets of the pump elements or progressive distributors with the lube lines.
These lines must be clean and free of any obstruction. You may not connect the lube lines to
the lube points unless the lubricant comes out free of air. Check all connections of the lube
lines for tightness and the lube points for air-free lubricant release.
Note that the pump unit, depending on the ambient conditions, is capable of building up
maximum pressures of far more than 500 bar!
Warning!
If the pump unit is not already fitted with pressure control valves
on delivery, the lube lines need to be retrofitted with suitable
protective elements in order to prevent the pump unit and lube
lines from overloading.
Warning!
Any pump pressure above the admissible operating pressure
of 250 bar may result in the destruction of the system and
situations endangering health!
6.6 Shutdown
The unit is shut down when switched off and disconnected from the external power supply.
Work on electric facilities may only be performed by skilled electricians
in conformity with DIN VDE 1000-10.
