d. Start the system; see page 37.
e. Raise or lower the adjustable crosshead to allow access to the unexposed section of the screw
columns. For 300DX frames, this would be the portion that is covered by the lower crosshead.
For 600DX frames, this would be portions of the screw columns that are below the top plate.
f. Shut down the system; see page 59.
g. Repeat steps a and b on this newly exposed area of each screw column.
h. For 600DX frames, repeat steps c through g. Continue to repeat these steps until the entire
length of both screw columns have been cleaned and greased.
i. Remove any equipment from the frame. In particular remove any towels from around the screw
columns and any towels that were used during the cleanup process.
6. Lubricate the drive chain:
a. For 600DX frames, remove the chain cover (9, Figure 15) from the top plate (use 5 mm hex
key).
b. Lubricate the exposed section of the drive chain (4) (use paint brush).
c. Remove yourself and any equipment from the frame. In particular, remove any towels from
around the screw columns.
d. Start the system; see page 37.
e. Raise or lower the adjustable crosshead until a new section of drive chain is exposed.
f. Shut down the system; see page 59.
g. Repeat steps b through f until all sections of the drive chain have been lubricated.
h. For 600DX frames, install the cover that was removed in step a.
7. Install any covers that were removed in step 3.
Inspect the hydraulic cylinder
The hydraulic cylinder should be inspected at the frequency stated in the “Preventative maintenance
schedule” on page 61. Perform the following:
Entanglement hazard exists. It is necessary to start up the system in order to complete
lubrication. Remove all body parts from the frame before starting the system. Be sure that
all equipment is removed from the frame.
For 300DX frames, it will be easier to reach the drive chain if the adjustable crosshead is at the top of its
travel.
