Automatic centralized lubrication (US gal):Three hydraulically powered Lincoln single line automatic lubrication systems are provided as standard, complete with time and volume variable controls. The two central lubrication circuits and open gear grease circuit are supplied by identical pump assemblies from refillable containers which have a capacity of 1x 600 and 1x 300 L (total 238 gal). Replenishment of the containers is through the Wiggins connections on the service arm.
