11. Malfunctions, causes, and remedies
The following tables provide an overview
of possible malfunctions and their causes.
Contact the SKF Service department if you
cannot remedy the malfunction.
IMPORTANT NOTE
Dismantling of the progressive metering
device is prohibited and voids any claims.
Defective progressive metering devices
must be replaced. Only SKF Service is ca-
pable of repairing them.
IMPORTANT NOTE
Only original SKF spare parts may be used.
Unauthorized alterations to products and
the use of non-original spare parts and ac-
cessories are prohibited.
WARNING
System pressure
Lubrication systems are pressur-
ized during operation. Lubrica-
tion systems must therefore be
depressurized before starting
assembly, maintenance or repair
work, or any system modifications
or system repairs.
11.1 Prior to beginning troubleshooting
The only condition that can cause a properly
configured progressive metering device to
jam/clog is the entry of contaminants into
the lubricant lines or an insufficient quantity
of lubricant.
Preventing contaminants from entering
during work or when refilling the lubricant
reservoir thus first and foremost requires a
clean work environment.
The progressive metering device outlet is
typically equipped with a fitting with check
valve. Do not replace this with another con-
nector because this may cause problems in
the progressive metering device’s operation.
Each outlet of the progressive metering
device can supply each bearing/each sec-
ondary metering device with a different,
precalculated quantity of grease. Therefore,
the position of each lubricant line to the pro-
gressive metering device outlet should be
noted prior to starting work.
IMPORTANT NOTE
Outlets of a progressive metering device
that are not needed must not be closed
because this will cause the progressive
metering device to block.
Unneeded outlets must be consolidated
with a neighboring outlet or connected to
the pump via the return line.
