Remove the cover (5) to access the lubrication nipple
(1). Lubricate the operator seat slew bearing with three
strokes of a hand-operated grease gun.
Clean and grease the chain (3) between the seat and
the steering column.
Also grease the seat slide rails (6).
If the chain is slack on the sprocket (2), loosen the
screws (4) and move the steering column forward.
Tighten the screws and check chain tension.

side with a forefinger/thumb at the marking (7) in seat
