INSTALLATION OF CAB

1. Replacing cab seals

the operator's cab assembly.
Weight of cab: Approximately 470 kg (1,036 lb)
(MSHA glass specification machine: Approximately
530 kg (1,169 lb))
2) Remove all the old seal with a scraper.
3) Remove any dirt or oil from the mounting surface of seal
(A).
4) Remove the paper backing from the new seal, then stick it
in the same position as the old seal.
The new seal is longer the necessary, so cut off the excess
portion.
2. Replacing dashboard seal
1) Remove the old seal and replace it with a new seal.
2) Coat the outside of the seal with grease (G2-Li).
(This is to make sliding easier and prevent deformation of
the seal when the cab is installed.)

turns.

Tighten in the order (N), (U), (Q), (R), (O), (T), (P), (S).
