16. Start the pump in manual operation mode of the control unit or with pressure air manual
control screw (21) of the pumping center's solenoid valve group, see chapter
3.3 Manual
operation
. When manual control screws are used, remove the cover plate (28) and the nut
(27) below the plate. After this remove the pumping center cover (26).
17. After the pressure hose is filled, stop the pump and connect the hose to the grease filter.
18. Fill the main header with lubricant by starting the pump in manual operation mode of the
control unit or with pumping center's solenoid valve group's manual control screws for
pressure air and lubrication lines (22 and 23). Stop the pump when the main header is
filled and air is removed.
19. Remove the plug from the tank connection of the pump and fasten the tank hose.
20. Ensure before connecting the tank hose that only grease (no air) is coming out of the hose.
If needed, pressurize the system again. Pressure air in the system prevents its trouble-free
operation.
21. Do a test pressurization of main header by increasing the pressure with the pressure
control device at the pumping center up to 250 bar (3600 psi) (24). The pump will stop due
to backpressure in 250 bar (3600 psi) if there is no air or leakage in the main header.
22. Set the maximum pressure of the pumping center with the pressure control device. The
maximum pressure of the pumping center 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 the
pumping center is 170 bar (2500 psi), the maximum pressure should be set at 200 bar
(3000 psi).
23. Replace the pumping center cover (26). Fasten the nut (27) and the cover plate (28).
3.2 Changing the lubricant barrel
Caution
Make sure that no impurities can enter the pump, follower plate or the
lubricant barrel during the barrel change procedures.
Caution
Clean or replace the grease filter cartridge when you are changing the
barrel. Remove pressure from the grease filter before opening it with the
help of venting screw which is located in the filter plug.
Caution
Ensure that the system is not under pressurization during the barrel change
procedures.
3.2.1 Maxilube-ECO
Note
Numbers in brackets are part numbers of drawing 461983A.
1. Ensure that the surroundings of the pumping center are clean. Impurities in the system
prevent trouble-free operation and cause damage when reaching the lubrication point.
2. Switch off the power on the pumping center when changing the barrel.
3. Disconnect the pressure air hose (6), the lubricant pressure hose (21) and the tank hose
(7) from the pump (5).
4. Lift out the pump from the lubricant barrel and place it on the pump bracket (27) or on a
clean, e.g. plastic base. Be careful not to damage the suction part on the bottom part of the
pump.
5. Remove the lid (4) from the top of the barrel.
