8.2.2 Maxilube with STA lid set
1. Ensure that the surroundings of the pumping centre are clean. Impurities in the system prevent trouble-
free operation and cause damage at the lubrication point.
2. Check the condition of the lubricant barrel. Damages on the surface prevent the follower plate from being
lowered (3, Figure 6).
3. Remove the barrel’s original lid and press the follower plate closely on top of the lubricant in the barrel.
Ensure that air is being removed under the follower plate.
4. Place the lid (1, Figure 6) on top of the lubricant barrel. Fasten the lid onto the lubricant barrel with wing
screws.
5. Pass the pump through the barrel lid and follower plate into the barrel. Lock the pump with a barrel nut (2)
so that the lower part of the pump is approximately 2 cm above the bottom of the barrel.
6. Fasten the pressure air hose (6, Figure 6) from the pressure air regulator to the bottom plate connection
A1 (Figure 12).
7. Fasten the lubricant tank hose (5, Figure 6) to the bottom plate and pump connection T.
8. Fasten the grease filter (10, Figure 6) to the bottom plate connection P (Figure 12).
9. Fasten the pressure hose (4, Figure 6) to the pump connection P.
10. Fasten the plug to the tank connection T of the pump.
11. Fasten the low level switch (8 & 9, Figure 6) to the pump.
12. Connect the low level switch cable (7, Figure 6) to the bottom plate connection D (Figure 12) and the ca-
bles of the channel pressure control units and shut-off valves to the pumping centre as described in the
electrical drawings.
13. Fasten the pressure air hose (6, Figure 6) to the bottom plate connection A2 (Figure 12) and the pressure
air connection (A, Figure 13) of the pump.
14. Set the pressure of the pumping centre's pressure air to 4 bar (60 psi) with the pressure air control device
(2, Figure 6) of the pressure air regulator.
15. Start the pump in manual operation mode of the control unit or with pressure air manual control screw of
pumping centre's solenoid valve group ( see Paragraph 9.5 Manual operation). When manual control
screws are used, remove the cover plate and the nut below the plate. After this remove the pumping cen-
tre cover.
16. After the pressure hose is filled, stop the pump and connect the hose to the grease filter (10, Figure 6).
17. Fill the main header with lubricant by starting the pump in manual operation mode of control unit or with
pumping centre's solenoid valve group's manual control screws for pressure air and lubrication lines. Stop
the pump when the header piping has been filled and air has been removed.
18. Remove the plug from the tank connection of the pump and fasten the tank hose to the pump connection
T.
19. Ensure before connecting the tank hose (5, Figure 6) to the bottom plate connection T that only grease
(no air) is coming out of the hose. If needed, pressurise the system again. Air in the system prevents its
trouble-free operation.
20. Do a test pressurisation of the header piping by increasing the pressure with the pressure control device
at the pumping centre to up to 250 bar (3,600 psi). The pump will stop due to backpressure in 250 bar
(3,600 psi) if there is no air or leakage in the header piping.
21. Set the maximum pressure of the pumping centre with a pressure control device. The maximum pressure
of the pumping centre should be set approximately 20% higher than the pressure by which the pressure
control unit acknowledgement pressure is reached. For example, if the acknowledgement pressure level
is reached when the pressure of pumping centre is 170 bar (2,500 psi), the maximum pressure should be
set at 200 bar (3,000 psi).
22. Fasten the lid of the pumping centre (Figure 9).
