Problems and solutions
Below is a troubleshooting table where the main faults, probable causes and possible solutions to

PROBLEM
CAUSE
REMEDIAL ACTION TO BE TAKEN
The pump motor does not work.
No current present.
Check the power supply.
The motor does not work.
Replace the motor. This operation may be carried out only by DropsA
S.p.A. engineers.
The pump works but grease does
not arrive at the lubrication points.
Lines disconnected.
Check the condition of the lines and the relative connections to the
fittings. Replace worn lines.
Blocked distributor
Clean or replace distributor.
The grease is distributed to the
lubrication points in irregular
doses.
The distributor is not properly
connected to the lubrication
points.
Check the dosages with the system diagram.
The pump begins the greasing
phase but ends it immediately
Defective motor or high output
absorption.
Allow to cool for a few minutes and try again. If the problem persists,
replace the motor. This operation may be carried out only by DropsA
S.p.A. engineers.
The pump does not dispense
grease.
The reservoir is empty.
Fill the reservoir with clean grease.
Air bubbles in the grease.
Disconnect the piping from the pumping element. Activate the pump
according to the manual operating cycle until grease comes out of the
pumping element without any air bubbles.
For the cartridge versions, you can manually press the cartridge itself in
order to favour priming of the pumping element.
Use of unsuitable grease.
Empty the reservoir and refill it with a suitable grease again.
The piston of the pumping
element is worn out.
Replace the pumping element (see Paragraph 6.3.1).
The delivery valve of the
pumping element is blocked.
Replace the pumping element (see Paragraph 6.3.1).
