Fan Speed Switch Adjustment
A fan speed switch is located in the fan. The fan
speed switch counts the revolutions of the three
mounting screws inside the fan.
1. Park the drill on a solid, level surface. Apply the
tractor park brake. Stop the engine and take the
key with you.
2. Remove the end cover from the fan shroud (1).
3. Slowly rotate the fan (2) to check the alignment of
the fan switch (3) with the three fan screws (4). If
the alignment is not correct, loosen the hardware
(5) at both ends of the switch mounting
bracket (6). Adjust the position of the fan speed
switch and tighten the hardware.
4. Check the distance (A) between the end of the
fan speed switch and the head of one of the three
fan screws. The distance must be 0 to 4 mm.
(Approximately the thickness of one wire tie.) If
the distance is not correct, use the adjusting nuts
on the fan speed switch to get the correct
distance.
5. Install the end cover on the fan shroud.
Implement Lift Switch Adjustment
Crush and Pinch Hazard
Do not place any part of body under
implement or near moving parts while
checking adjustments. Have another
person make sure the tractor is not started
and the tractor controls are not moved
during the adjustment procedure.
An implement lift switch (1) on the drill turns seed
metering off when the implement is raised. To adjust
the switch activation height, first locate the
implement lift switch on the implement (center
section, upper parallel arm at right rear).
Adjust the implement lift switch for activation height if:
Any changes have been made to tool bar height
(page 23).
The implement lift switch was removed for any
reason.
1. Park the drill on a solid, level surface. Fold the
wings to prevent the lift lock from engaging.
2. Lower the openers until at a height where
seeding should start (usually just above the
ground).
3. Turn off the tractor and remove the key.
4. Securely support the center section tool bar at
this height with jack stands or blocks.
5. Check the distance between the end of the
implement lift switch (1) and the face of the lift
arm (2). The distance must be 0 to 8 mm.
(Approximately the thickness of two wire ties.) If
the distance is not correct, use the adjusting nuts
on the implement lift switch to get the correct
distance.
6. Put the tractor key in the ON position to supply
current to the implement lift switch. Do not start
the tractor.
