Malfunction Cause Remedy
System malfunction
o Piston detector on main metering
device has indicated that the system
is not working.
• Loosen both lubrication lines on the last metering section of the
main metering device, switch on the lubrication system, and check
whether lubricant discharges without bubbles. If lubricant dis-
charges without bubbles, tighten both lubrication lines and repeat
the procedure on all secondary metering devices, starting from
the closest progressive metering device. Vent the possibly defec-
tive progressive metering device again; replace in the event of
reoccurrence.
• If all progressive metering devices function properly, check the
electrical connection of the piston detector and the piston detector
itself for proper function.
No pressure build up in
the main line
o Pressure relief valve does not close • Clean or replace pressure relief valve.
Only use original SKF spare parts.
o Unsuitable lubricant (see technical
data)
• Remove lubricant from entire system and dispose of lubricant in
the proper manner; fill system with suitable lubricant
o Fill level too low • Top up lubricant
o Pump element is defective • Inspect pump element and replace if necessary
