8.3. Instructions for replacing hydraulic parts<br />
1. Set the telescopic forks on the hip level, bend the mast forward and remove the ignition key from<br />
the contact.<br />
2. Take the outer fork off by removing the spiral clamping bushes (be careful not to damage the<br />
piston rods).<br />
3. Unscrew the hose couplings a little off the hose above on the rug of the telescopic fork so that the<br />
piston rods do not pull vacuum when demounting the telescopic forks.<br />
4. Unscrew the locking screw situated between the cylinder heads.<br />
5. Place a reservoir under the telescopic forks. Use the cylinder head key to unscrew the cylinder<br />
heads. Take care that the right cylinder head (as viewed from the position of the diver) is<br />
unscrewed first, along with the plastic bung under the locking screw.<br />
6. Carefully pull out the piston rods.<br />
7. The piston can now be unscrewed. To avoid damage to the piston rod it must be clipped onto the<br />
mounting clip. The cylinder head can now be unscrewed from the piston rod.<br />
8. Replace the parts.<br />
9. Remove Loctite from the screw thread of the piston rod.<br />
10. Clean piston rod and screw thread with Loctite 7063.<br />
11. The cylinder head can now be put on the piston rod again.<br />
12. When mounting the piston on the piston rod it must be locked with Loctite 270.<br />
13. Keep the piston rod (along with piston and cylinder head) straight before the cylinder and tap it<br />
carefully directly to the inside.<br />
14. Smear the screw thread of the cylinder head with Copaslip.<br />
15. Tighten again the cylinder head carefully with a cylinder head key.<br />
16. As all piston rods sit again in their place, the locking screw must be screwed up again above the<br />
plastic bung.<br />
17. Now the hose couplings of hose must be screwed up.<br />
18. Take care that the piston rods should be unscrewed for about 150 mm.<br />
19. The outer forks can be now mounted again. Take care that the clamps of the piston rods are<br />
located exactly under the holes in the outer fork. Insert a screwdriver or a bolt in one hole and hit<br />
the new spiral clamping bushes in the other gat with a hard hammer. The screwdriver or the bolt<br />
can be taken from the hole and now the spiral clamping bushes can be knocked in here.<br />
20. Start the fork-lift truck and extend and retract the telescopic forks several times.<br />
