Central lubrication system
Check filling level
A
The lubricant tank should always be filled
sufficiently so that the system cannot "run
dry", ensuring sufficient drive chain lubri-
cation and eliminating the need for time-
consuming bleeding of the system.
- Always maintain a fill level above the
"MIN" mark (a) on the tank.
Top up lubricant tank
- Unscrew cap (b) and fill tank from
above.
A
When the lubricant tank is completely empty, the pump may have to run for up to 10
minutes until the full delivery rate is achieved after filling.
Bleed central lubrication system
Bleeding the lubrication system is nec-
essary if the central lubrication system
has been operated with an empty lubri-
cant tank.
- Release the main lubrication line (a)
at the distributor (b).
- Start up the central lubrication sys-
tem with the filled lubricant tank (c).
- Allow the pump to run until lubricant
emerges from the previously re-
leased main line (a).
- Reconnect the main line (a) to the
distributor.
- Release all distribution lines (d) from
the distributor.
- Reconnect all distribution lines as soon as lubricant has emerged.
- Check all connections and lines for leaks.
