Operation
Safety indications
1 013A94
WARNING!
Never exceed the centralized lubrication
system’s max. operating pressure of
300 bar.
Do not carry out any assembly or disas-
sembly works while the system is pressur-
ized or the pump/machine is operating.
Before using any synthetic lubricants,
check their compatibility with the materials
of the metering devices and other system
components.
Preparation for operation
of centralized lubrication pump and timer:
- see User Manual for the respective components
- see Instructions and Safety Indications by the manufac-
turer/ supplier of the machine.
Start-up
1 013A94
CAUTION!
Wear protective glasses when venting the
lubricant lines; avoid splashes.
Before the start-up
see Instructions and Safety Indications by the manufac-
turer/ supplier of the machine
Prime and vent the main line
Â
Before the metering devices can be operated, the follow-
ing measures must be carried out:
- Fill main line with lubricant
- Vent stub lines and ascending lines of the main line
- When filling and venting the lines, operate pump at low
pressure
- Make sure helpers with containers are available to col-
lect the leaking lubricant during the venting procedure.
- Check lubricant main line for leakages.

IMPORTANT NOTE
The QSL metering devices have been
designed for a max. operating pressure of
300 bar.
Â
Before the machine start-up, after completion of installa-
tion or repair works:
- main and stub lines as well as metering devices must
be primed and vented.
- feed lines must be primed and connected
- all metering devices must have been checked with re-
gard to their functional capability
- all metering devices as well as the timing of the lubricat-
ing intervals must be adjusted according to the prescrip-
tions.
- See Instructions by the machine manufacturer.
Verify functional capability of QSL metering devices
Â
Adjust pump and timer in such way that the recommended
operating pressure of 140-300 bar is adhered to.
Â
Trigger lubrication pulse manually
(see User Manual for the respective centralized lubrication
pump, timer and QSL metering device)
With an operating pressure
≥
140 bar, the indicator pin is
extracted.
After a pressure relief down to
≤
60 bar the indicator pin is
retracted again.
Incomplete venting of the main line may impact the func-
tion of the metering devices.
Priming of lubricant feed lines
Precondition:
The proper functioning of all metering devices of the sys-
tem has been stated (see above, chapter "Verify func-
tional capability of metering devices").
Â
Before connecting the lubricant feed lines to the lubrica-
tion points:
- Prime lubricant feed lines with lubricant. Make sure to
use only the lubricant specified by the machine manu-
facturer
- Fill the lines with lubricant by means of a grease gun
- Check for leakages on the lubricant feed lines and, if
there are any, eliminate them
- Collect lubricant leaking from the end of the lubricant
feed line during the filling process in containers
Â
When all lines are primed: Connect the lubricant feed
lines.

IMPORTANT NOTE
In the case of backpressures in lubrication
point lines of
≥
100 bar or if several injec-
tors are combined to one lubrication point,
use check valves.
Check valves for connection at lubrication
point outlets:
