Packer Air System
There may be times when the packer is unable to complete a full cycle. If this is the case, the problem
may be related to the packer air system.
To fix the problem:
1. Apply all safety measures to ensure safety around the vehicle at all times.
2. Remove one of the air tubes from the packer section actuator by pushing on the green sleeve with
a screwdriver and pulling the tube.

3. Inject compressed air into the actuator to ensure that the spool moves freely inside the valve.
Check the movement of the spool, if any, on the lower side of the valve (see Figure 8-7, picture on
the right).
4. If the spool is not moving freely, lubricate or replace the air actuator.
5. Try to operate the packer and see if air comes out of the air tube.
6. If no air comes out of the air tube, check the tube is not blocked or bent and, if necessary, replace
the air tube.
7. Repeat Steps 2 - 6 for the other air tube.
