3. Checking of the operations of the drive
pedal
Check the operation and position of the drive
pedal. The pedal shall move to its mid-position
as the foot is removed off the pedal. Lubricate
the drive chain and centralising device when
necessar y.
The frame lock and the brakes shall be disen-
gaged slightly before the harvester starts
moving.
The disengagement is controlled by an induc-
tive switch located on the drive pump. Turn
off the engine and secure the drive pedal in
its forward drive position. The distance of the
inductive switch from the lever arc shall be
0.5-1.5 mm. Release the drive pedal and adjust
the switch in the middle of the lever notch. The
relation of the brake and frame lock opera-
tions to the start-up of the harvester can be
adjusted by changing the distance of the induc-
tive switch from the lever arc. The distance
shall, however, remain within the recommen-
ded limits. See fig. 39.
4. Use Of An Additional Heater And Air
Conditioning Outside The Heating Season
The heater shall be used approx. once a month
outside the heating season, too. This is done
to prevent the fan motor and water pump from
getting stuck. Also air conditioning must be
used at least once a month.
2. Changing of engine oil and filter
Keep the engine running until it warms up.
Open the drain plugs A in the underpan and the
engine sump . Drain the oil into a pan. When all
the oil has been drained, close the drain plug
with a new gasket (fig. 37).
The oil filter is replaced every time the oil is
changed. Clean around the oil filter. Remove
the old filter using a filter key. Coat the gasket
of the new filter lightly with new oil (fig. 38),
and make sure the gasket surfaces are clean.
Attach the filter manually. Wipe off any exces-
sive oil. Pour new oil through the filler B to the
top mark on the dipstick. Pay attention to the
amount of oil poured into the filter.
Acceptable oil types and amounts are given in
the Lubrication Table and the Engine Manual.
For further instructions, see the Engine
Manual.
NOTE! Only use oil recommended by the
manufacturer
Check the engine breather pipe every time the
oil is changed. The pipe shall be clean inside
and it must not be dented.
