OPERATION
5.3 PRE-OPERATION CHECKLIST
5.4.1 PRE-START INSPECTION
1. Read the Operator’s Manual.
2. Check that the hydraulic lines and electrical harnesses
are routed where they will not contact moving parts. Be
sure all components are clipped, taped or tied securely
in place.
3. Check that all guards are installed and secured.
4. Check that all required nuts and bolts are installed and
tightened to their specified torque.
5.4 MACHINE BREAK-IN
Ef fi cient and safe operation of the Air Reel requires that each
operator reads and understands the operating procedures
and all related safety precautions outlined in this section.
A pre-operation checklist is provided for the operator. It is
important for both personal safety and maintaining the good
mechanical condition of the machine that this checklist is
followed.
Before operating the machine and each time thereafter, the
following areas should be checked off:
1. Service the machine per the schedule outlined in the
Service Record.
2. Use only a combine of adequate power and specifica-
tions to operate the machine.
3. Check that all guards are installed, secured and func-
tioning as intended. Do not operate with missing or
damaged shields.
4. Ensure that the machine is properly attached to the
header and that mechanical retainers, such as quick
pins, are installed.
5. Check the cutterbar, reel area and drives for entangled
material.
6. Check the chains and sprockets for proper tension and
alignment. Adjust as required.
7. Visually inspect the hydraulic system for leakage, loose
fittings, and damaged hoses. Tighten fittings, replace
damaged components and wipe up leaked or excess
hydraulic fluid.
8. Check condition of driveline slip clutch friction discs.
If installing replacement discs, adjust spring height to
original height. Deviation from original setting may be
needed depending upon disc wear. Run-in is recom-
mended at the start of the season (see Service and
Maintenance Section).
9. Check condition of auger driveshaft slip clutch friction
discs. Run-in is recommended at the start of the season
(see Service and Maintenance Section).
Place all controls in neutral or off, stop combine engine,
set parking brake, remove ignition key, wait for all mov-
ing parts to stop, then properly block machine before
servicing, adjusting, repairing, or unplugging.
WARNING
To prevent burn-up of slip discs, the torque limiter must
be adjusted prior to use.
IMPORTANT
5.2.3 TORQUE LIMITER (SLIP CLUTCH) RUN-IN
The Air Reel comes equipped with a torque limiter (slip
clutch) on the main drive. The torque limiter is set in the
engaged position from the factory. Before use, the slip clutch
must be slipped and adjusted to ensure proper function.
Allowing the torque limiter to slip:
1. Loosen the center locknuts on the torque limiter (Figure
41) so that the pressure is relieved from the pressure
plates.
2. With the combine engine at idle speed, engage the PTO
for 2-3 seconds to make the torque limiter slip.
Do not
allow the torque limiter to slip for more than 2-3
seconds at a time to prevent damage to the linings
.
3. If the torque limiter does not slip, repeat the procedure 2
or 3 times. If it still doesn’t slip, check that all the center
locknuts are loosened and not placing tension on the
pressure plates.
After the torque limiter has slipped, it must be adjusted to
the tension required to operate the header. The goal of this
procedure is to have the torque limiter slip momentarily upon
initial startup and then operate normally. The slip clutch
must not slip during normal operation.
1. Slowly engage the PTO with the engine running at idle
speed.
2. If the torque limiter does not slip, shut off machine and
loosen the center locknuts in 1/4 turn increments until
it slips momentarily when the header is engaged. If the
torque limiter continues to slip after start-up, tighten the
center locknuts in 1/4 turn increments until it slips only
momentarily when the header is engaged.
