OPERATION
5.3 PRe-oPeRaTion checKliST
5.4.1 PRe-STaRT inSPecTion
Read the Operator’s Manual.
1.
Check that the hydraulic lines and electrical harnesses are
2.
routed where they will not contact moving parts. Be sure all
components are clipped, taped or tied securely in place.
Check that all guards are installed and secured.
3.
Check that all required nuts and bolts are installed and
4.
tightened to their specified torque.
Ensure cylinder stops are installed as needed (See
5.
Section 5.2.1).
5.4 machine bReaK-in
Efficient 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-op-
eration checklist is provided for the operator. It is important for
both personal safety and maintaining the good mechanical con-
dition of the machine that this checklist is followed.
Before operating the machine and each time thereafter, the fol-
lowing areas should be checked off:
Service the machine per the schedule outlined in the Service
1.
Record.
Use only a combine of adequate power and specifications
2.
to operate the machine.
Check that all guards are installed, secured and function-
3.
ing as intended. Do not operate with missing or damaged
shields.
Ensure that the machine is properly attached to the header
4.
and that mechanical retainers, such as quick pins, are in-
stalled.
Check the cutterbar, reel area and drives for entangled
5.
material.
Check the chains and sprockets for proper tension and align-
6.
ment. Adjust as required.
Visually inspect the hydraulic system for leakage, loose fit-
7.
tings, and damaged hoses. Tighten fittings, replace damaged
components and wipe up leaked or excess hydraulic fluid.
Check condition of driveline slip clutch friction discs. If install-
8.
ing replacement discs, adjust spring height to original height.
Deviation from original setting may be needed depending
upon disc wear. Run-in is recommended at the start of the
season (see Service and Maintenance Section).
Check condition of auger drive shaft slip clutch friction discs.
9.
Run-in is recommended at the start of the season (see Ser-
vice and Maintenance Section).
Place all controls in neutral or off, stop combine engine, set
parking brake, remove ignition key, wait for all moving parts
to stop, then properly block machine before servicing, ad-
justing, repairing, or unplugging.
WaRninG
To prevent burn-up of slip discs, the torque limiter must be
adjusted prior to use.

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 posi-
tion from the factory. Before use, the slip clutch must be slipped
and adjusted to ensure proper function.
allowing the torque limiter to slip:
Loosen the center locknuts on the torque limiter (Figure 47)
1.
so that the pressure is relieved from the pressure plates.
With the combine engine at idle speed, engage the PTO for
2.
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
.
If the torque limiter does not slip, repeat the procedure 2
3.
or 3 times. If it still doesn’t slip, check that all the center
locknuts are loosened and not placing tension on the pres-
sure plates.
After the torque limiter has slipped, it must be adjusted to the
tension required to operate the header. The goal of this proce-
dure is to have the torque limiter slip momentarily upon initial
startup and then operate normally. The slip clutch must not slip
during normal operation.
Slowly engage the PTO with the engine running at idle
1.
speed.
If the torque limiter does not slip, shut off machine and loosen
2.
the center locknuts in 1/4 turn increments until it slips mo-
mentarily 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.
