Put the assembled parts into a plastic dust bin or similar vessel, fit the coupling to the top of the
cylinder, attach a hand pump to the coupling and pump out the ram, importantly,
by hand.
The ram can now be removed from the bearing ring and all seals will be accessible.
The ram has been fitted with a relief valve plug, this also contains seals, to remove the part the
two M8 tapped holes can be used to unscrew the plug, the two relief valves have been careful
set to blow off at a set pressure, these can be removed with a 17mm socket and 5mm allen key,
care should be taken not to disturb the settings.
When re assembling the relief valve plug with the ram, first fill the ram with oil to the bottom of
the counterbore, smear silver goop on to the threads of the plug, screw in the plug, remove the
set screw and ball in the top of the plug and top up the inside of the ram with oil until it fills the
screw hole, fit the ball and screw and lock tight.
Check that the plug and the relief valves are tight and below the top face of the ram.
Fit the ram into the bearing ring, place the cylinder upside down under a press, position the ram
on top of the cylinder and push home.
Position the assembly on top of the cutter, put grease on the threads and screw in the cylinder
using the two tapped holes and the flat bar, remove the bar, replace the screws and fit the
couplings.
