With the Control Panel powered move a solid metallic ferrous object (i.e. 2lb Ball Pein
hammer) over the sensor. The second indicating LED should illuminate ‘yellow’ to show the
sensor has ‘seen’ the object.
•
Repeat the test with a person viewing the red sensor-indicating lamp on the Control Panel.
The lamp should illuminate when the sensor is activated.

Checking for Airlocks
The following shows steps taken to check for airlocks.
•
Remove the delivery hoses from the Cabinet hose outlet. Operate the Run button on the
control panel and check grease flows freely from each outlet.
•
Remove delivery hoses from the Blade’s. Operate the Run button on the control panel and
check grease flows freely from each outlet.
Note:
•
If the test was not satisfactory,
o
Check the reservoir is full of grease.
o
Clear the block within the grease path.
o
Operate the Pump by activating the ‘Run’ button.
Do not run for more than 5 seconds with a 20 second interval between operations.
Air locks that are present on arrival at the lubricator will give you certain information into why the
lubricator has not had a sufficient grease output.
If the lubricator has not used any grease, but no air locks are present other corrective actions
should be undertaken.

Inspection of the Blade’s
12.12.1
Visually check the Blade’s for damage and / or wear. Record and report findings.
12.12.2
Check that each port is clear and that there is a vertical stand of grease from each running
rail Blade.
12.12.3
Check Blade height with reference to initial installation height settings
12.12.4
Check that the fastenings are secure.
12.12.5
Operate the pump from the Test button and ensure all of the ports on the top face of the
spreader bar are dispersing grease. This will show if there is hardened grease, inside the
Blade and/or if the Blade slots are blocked.
12.12.6
If Blade are partially blocked:
o
For each delivery hose run close flow valves on all Blades other than the Blade to be
worked on (note on two blade systems there are no flow valves).
o
Cover each working port while operating pump, this should clear minor blocks.
o
If blockage persists then strip and clean Blade
12.12.7
If Blades are fully blocked then remove, strip and clean.
