AUTOMATIC CENTRALIZED ATTACHMENT LUBRICATING SYSTEM (Optional equipment) Your machine is fitted with a centralized lubricating system, allowing to reduce to a minimum the time which is necessary for the daily lubrication. All the lubrication points for the swing ring ball races (metering device pos. 22) and for the working attachment are connected to this automatic lubricating system and are greased at regular intervals while working. Only some bearings of the working tool (grab, clamshell,

type of the tool). CONSTRUCTION The centralized lubricating system mainly consists of the lube pump 1 (fig. 42) which is mounted to the front face of the hydraulic tank, just beside the serially fitted lube pump 2 for the swing ring teeth lubrication. Both lube pumps 1 and 2 are identical. Each lube pump consists of a transparent container, an electric driven pump and a control unit which starts and stops the lubricating procedures. During a lubricating procedure, all lube points are lubricated in a certain sequence.
42
After completion of a lubrication procedure, the switch mounted to the exit for the last lube point (fig. 43, pos.?6) automatically turns off the pump. The flow sequence and amount of lubricant for each lubrication point depend on the combination of the metering devices and lubrication lines.
OPERATION Without any action by the operator, the lubrication restarts automatically after the a preadjusted "pause time" is over and stops after all points are lubricated. When the lube pump 1 (resp. the lube pump 2) is greasing, the control light inside the push button S84-1 resp. S84-2 (fig. 44) is on continuously.
43
If blinking, the control light S84-1 or S84-2 indicates that the corresponding lubrication circuit 1 or 2 is defective (lubricating procedure did not stop after approx. 30 minutes). Possible causes: -
Plugged or kinked lubrication line.
-
Defective switch or defective wire.
-
Not enough grease in the grease tank.
-
Problem in the 24 V electrical circuit for the motor.
Immediately locate and remedy the cause of the trouble. 44
