Seat bearing - Lubrication
Remove both steps from under the operator’s platform,
or one step and cover plate on the other side of the roller
if fitted with a cab.
Lubricate the seat sliding rails for transverse travel with
five strokes of a hand-operated grease gun. Grease all
four nipples, two of which (1) are accessible from each
side.
Also grease the slew bearing of the seat with a few
strokes of the gun. The lubrication nipple (3) is acces-
sible after the cover on the seat frame underneath the
front of the seat is removed.
Also lubricate the seat locking mechanism, both for
transverse travel and slewing. Use engine oil or drum
oil.
If the seat begins to bind when resetting, then it
should be lubricated more often than specified
here.
Remember that the chain is a vital part of the
steering mechanism.
Remove the cover (5) to gain access to the lubrication
nipple (1).
Lubricate the slew bearing of the operator’s seat with
three strokes of a hand-operated grease gun.
Lubricate the seat locking latch (7), accessible from
below.
Also grease the slide rails of the seat (6).
If the seat begins to bind when resetting, it
needs to be lubricated more often.
Clean and grease the chain (3) between the seat and
the steering column.
If the chain becomes slack on the cogwheel (2), loosen
the screws (4) and move the steering column forward,
tighten the screws and check the tension of the chain.
