Bleeding Air from Tool Unclamp Cylinder Oil System
Oil is compressed by the tool unclamp cylinder which then presses down on the drawbar that holds the
tools in place. If air gets into this system, the tool unclamping process will not work correctly. This is
usually indicated by seeing oil leaks at connections or seeing air bubbles in the oil reservoir, see figure 6.15.
Figure 6.15
Please also refer to drawing 27500-1 at the back of the manual.
To bleed air from the system, follow this procedure.
1.
Make sure all connection points are tight and no air can get into the system. If the connection
points are tight and not leaking but you notice oil leaking from the tool clamp cylinder, the
cylinder will need to be replaced.
2.
Make sure to fill the oil reservoir cap to the fill line. If the system has been leaking the oil level
will have dropped.
3.
Press the unclamp button on the front of the head a number of times over and over until you
do not see any more oil bubbles in the oil reservoir. The air should escape from the top of the
oil reservoir tank.
