9.11 CHAIN REPlACEMENT
1) Turn off the power and disconnect the cord from the machine.
2) Remove the side covers as outlined in Section 9.1.
3) Remove at least 3 sets of stairs as outlined in Section 9.9 to expose a significant portion of the chain.
4) Before removing the chain, measure the distance of the chain run from the middle of the front bearing seat to the middle of the rear bearing
seat (Figure A). This distance should be 941mm.
5) If this length is not 941mm, it needs to be adjusted. Loosen the vertical bolts on the bearing seat, then adjust the length by adjusting the
horizontal screw. Tighten the vertical bolts to tighten the bearing seat in place. The vertical bolts should be torqued to 60 N-m.
6) Rotate the chain until a spring clip is in a convenient location and remove it (Figure C).
NOTE:
This chain link will normally be painted to
make it easier to identify.
7) Remove the join plate on the chain (Figure D).

8) Remove the 2 seal rings from where the join link was just removed (Figure E).
9) The chain can now be removed.
10) Reverse Steps 1-9 to install a new chain. When installing a new chain, it is important to pay attention to the join plates. The join plates are
wider than the chain itself. It is important that the side of the join plates that are flush with the rest of the chain get installed to the inside of the
chain path (Figures F & G).
11) Test the Climb Mill for function as outlined in Section 9.21.
