Use the following procedure to remove and replace the TRA cylinders.

1. Ensure Rising Table and TRP are at their Home positions.

2. Power down the machine and disconnect the air supply

3. When removing the cylinders the TRP arms may lift. Hold the TRP down and secure

with cable ties.

4. Cut all cable ties connecting the pneumatic tubes and sensor wires to the cylinder.

5. Disconnect all pneumatic tubes from the 4 x flow controllers per cylinder

6. Disconnect the 2 x pantograph springs per side by removing L Bracket from the sliding

block. Do Not Use Pliers

7. Remove sensors and straps from Left Hand cylinder. It is not necessary to unplug the

sensors from the electrical interface bracket. If this is done ensure loom / connectors

are clearly labelled.

8. Remove the M8 nuts from the tip of the cylinder rods. Note: these nuts are secured

with ‘Green’ thread lock compound so maybe tight. These nuts will not be required

when fitting the new cylinder as new nuts are provided.

9. Remove the M20 nuts from the fixed end of the cylinder. Note: these nuts are secured

with ‘Blue’ thread lock compound. These nuts will not be required when fitting the new

cylinder as new nuts are provided. Note: Using another spanner on the flat section of

the cylinder can hold the cylinder still whilst these nuts are loosened and removed.

10. Remove the cylinder from the TRS assembly.

11. Fit the new cylinder between the brackets. Fit the M20 nut using ‘Blue’ thread lock

compound. Do not fully tighten the nut at this stage.
