tube holder (Fig. 1).
Remove the protective caps from the ends of the threads of
the hose clamps.
Use a spanner to remove the hose clamps from the tube
cylinder (Fig. 2) and the rotary inlet (Fig. 3).
Remove the adhesive tape from the old lifting tube.
Unscrew the old lifting tube from the tube mounting of the tube
cylinder (Fig. 4).
Unscrew the lifting tube from the tube mounting of the rotary
inlet (Fig. 5).
Lightly grease the threads of the tube mountings (Fig. 6).
Mount the new lifting tube with the reinforced section at the

Fully screw the new lifting tube onto the threads of the tube
cylinder (Fig. 8).
Wind tow full turns of adhesive tape (Coroplast) around the
ends of the lifting tube to seal it to the tube cylinder (Fig. 9)
and the rotary inlet (Figs. 10, 11).
Place the hose clamps on the ends of the lifting tube and
tighten them with a torque of 10 Nm, using a torque wrench
