Tilting ram:
This is done with the roller in the transport position. Remove the hose. It is
recommended that a bucket be placed underneath to catch any oil. Remove
split rings and pins, and the ram, weighing 26 kg, can be removed.
Assembly is done in the reverse order.
There must be an air plug in the top connection. After assembly, lift the side
sections clear of the transport beaings a couple of times (see under operation).
Check that the oil connections are tight.
Replacing the hydraulic sealings:
REMOVAL:
1. Empty the oil from the ram, compressed air can be used to move the
piston rod back and forth, to press the oil out.
2. Place the piston rod in the middle position. Unscrew the gland (pos. 3) 30
mm out. If the gland can't be unscrewed, it may be necessary to warm it up
to 300°c. Let it cool off slowly. With the gland screwed out, pull the piston
rod out towards the gland. Screw the gland all the way off, and the piston
rod can now be removed.
3. Remove the self-locking nut (pos. 10).
4. Remove the sleeve (pos. 4).
5. Pull the gland off the piston rod (pos. 3).
6. The sealings above the sleeve are now removed, (pos. 5,6,7,8,9), use
either a awl or a screwdriver.
7. Clean all the parts. Check for filings and shavings, make sure that their is
no rust in the gland. If this is the case, it must be romoved.
ASSEMBLING:
1. Assembel the new sealings in the gland and sleeve. The scraper ring pos.
5 is mounted with the help of a pipe, that fits around the outside of the lip.
The sleeve (pos. 9) is mounted with a round iron bar or screwdriver
2. The threads on the gland and ram housing should be greesed before assem-
bling, (rust protection).
3. The gland pos. 3 is now mounted over the piston rod.
