III. General safety instructions
Operation in accordance with
specifications
The short-cut forage wagon is designed solely for
normal agricultural use (operation in accordance with
specifications).
Any use of the machine for other purposes is deemed
not to be in accordance with specifications. The
manufacturer bears no responsibility for any resulting
damage – such use is entirely at the operator's risk.
Use in accordance with specifications also includes
observing the operating, maintenance and service
instructions prepared by the manufacturer.
The short-cut forage wagon must only be used,
maintained and repaired by personnel who are
acquainted with the machine and have been informed
of the danger involved.
The applicable accident prevention regulations and all
other generally recognized safety, health and road
traffic regulations must be observed.
Any unauthorised alterations to the machine render any
liability for damage undertaken by the manufacturer null
and void.
Basic rule:
1. Take note of both the regulations in these
operating instructions and also the general safety
and accident prevention regulations!
2. The attached warning and information signs give
important advice for safe operation. Observing
them will improve your safety!
3. When using public roads, make sure you observe
the relevant traffic regulations.
4. Make sure you are familiar with all equipment
and controls before you begin working with the
machine. It is too late when you are operating the
machine!

6
22. Keep guards attached and always put in protective
position!
23. Do not operate trailed implement unless all guards
are attached and in protective position!
24. With single-axle trailers pay attention to danger of
tipping if unevenly loaded, in particular when
uncoupling and when uncoupled.
– Permissible coupling load!
25. Loaded single-axle trailers must not be transported
using the support wheel!
26. Drawbar height adjustment for load-bearing
drawbars is to be carried out by specialist
workshops only!
27. With single-axle trailers, pay attention to reduced
load on front axle of tractor and impaired steering
due to coupling load!
PTO shaft operation
1. Do not use universal drive shafts other than those
specified by the manufacturer!
2. The guard tube, the guard cone of the universal
drive shaft and the PTO shaft guard – also on the
implement side – must be installed and in proper
condition!
3. Observe the tube overlap prescribed for universal
drive shafts in transport and operating position!
4. Before installing or removing universal drive shafts,
disengage the PTO, stop the engine and remove
the ignition key!
5. When using universal drive shafts with an overload
or free-wheel clutch mechanism which is not
covered by the guard on the tractor, the overload
or free-wheel clutch mechanism must be installed
on the implement side!
6. Always make sure that the universal drive shaft is
properly installed and secured!
7. Hook the chains to secure the universal driveshaft
guard against rotating with the shaft!
8. Before engaging the PTO shaft, make sure that the
selected PTO speed of the tractor matches the
permissible implement speed!
5. When travelling with trailed implement, the
possibility of individual braking must be excluded
(lock pedals)!
6. Attach implement only to the devices provided for
this purpose!
7. Observe the maximum permissible load for the
trailer coupling!
8. (Observe maximum permissible fifth-wheel
pressure on swinging drawbar)!
9. Park trailed implement safely!
10. When transporting, secure movable components
with the securing devices provided to prevent
alteration in position!
11. (Danger at crushing and shearing points when
operating support devices!)
12. Put all equipment in transport position before on-
road driving! Note hydraulically operated
articulated drawbar!
13. Do not enter floor conveyor when machine is
operating!
14. Due to their function, input and output units such
as pick-up, belts, metering equipment and output
rollers cannot be made fully safe by design
measures. A safe distance must therefore be kept
from these moving parts during operation! The
same applies to all additional equipment
15. Keep clear of discharge area!
16. There are hazarous tools under the guards.
They can continue to run after the drive has been
switched off. So keep clear of these parts until they
have come to a standstill.
17. Switch off the drive, stop the engine and remove
the ignition key before carrying out repair, service
or cleaning work or rectifying faults.
18. When working under raised covers ensure that
they are supported properly!
19. Take suitable protective measures (gloves, boots
etc.) when handling sharp parts, e.g. cutter blades!
20. Always wear eye protectors when resharpening
blades.
21. Keep clear of movable covers!

7
9. When using the ground speed PTO, note that the
speed is independent of the travelling speed and
the direction changes when reversing!
10. Before engaging the PTO, make sure that no-one
is in the danger area of the implement!
11. Never engage the PTO while the engine is
stopped!
12. No-one should be standing in the range of the
turning PTO or universal drive shafts when working
with the PTO shaft!
13. Always switch off the PTO shaft when extreme
angles occur and it is not required!
14. Danger! Due to their inertia, working components
continue to rotate for some time even after the PTO
has been disengaged! Keep clear of the implement
during this time. Be sure the implement has come
to a complete stop before starting any work on it.
15. Disengage the PTO, stop the engine and remove
the key from the ignition before cleaning, lubrica-
ting or making any adjustments to the implement
or the PTO!
16. After detaching the universal drive shaft, always
place it on its support!
17. After detaching the universal drive shaft, place the
protective cover over the PTO stub!
18. Immediately repair any damage before resuming
operation with the implement!
Hydraulics
1. The hydraulic system is pressurised!
2. When connecting hydraulic cylinders and motors,
make sure the hydraulic hoses are connected
according to specifications!
3. When connecting hydraulic hoses to the tractor
hydraulics, make sure that all hydraulic pressure
has been released from both the tractor and the
implement!
4. In case of hydraulic connections between tractor
and implement, the coupling sleeves and plugs
should be marked to ensure a proper connection!
If the connections are switched, the function is
reversed (e.g. raising/lowering) – danger of
accidents!
5. Check the hydraulic hoses at regular intervals and
replace them if they are damaged or worn. The
new hoses must satisfy the technical requirements
of the implement manufacturer!
6. To avoid injury, use suitable tools and aids when
tracing leaks!
7. Escaping pressurised fluid (hydraulic oil) can
penetrate the skin and cause serious injury! In
case of injury, immediately consult a doctor! Dan-
ger of infection!
8. Before working on the hydraulics, lower the
implement, relieve the hydraulic pressure from the
system and stop the tractor engine!
Tyres
1. When working on the tyres, the implement must be
safely lowered and secured against rolling (wheel
chocks).
2. Installation of tyres and wheels requires special
knowledge and proper installation tools!
3. Repairs on tyres and wheels must be carried out by
specially trained personnel using proper installation
tools!
4. Check the air pressure at regular intervals! Inflate
the tyres to the recommended tyre pressures!
Brakes
1. Check that the brakes function before each
journey!
2. The brake systems must be inspected regularly!
For details see the adjustments and service
chapter.
3. Adjustment and repair work on the brake system
must only be carried out by specialist workshops or
recognised brake services! Use only prescribed
brake fluid and change as specified!

8
Maintenance
1. Repair, maintenance and cleaning work and
correcting operating faults should only be carried
out when the drive and engine are switched off!
– Remove the ignition key!
2. Regularly check all nuts and bolts and retightened
if necessary!
3. Support the implement with adequate jacks before
carrying out any maintenance work on the raised
implement.
4. When changing working elements with cutting
edges, use appropriate tools and wear protective
clothing!
5. Dispose of oil, grease and filters according to
regulations!
6. Before working on any electrical installations,
always disconnect the power supply!
7. Protection devices and guards subject to wear
must be checked regularly and must be replaced in
time!
8. When using an electric welder on the tractor or
mounted implements, disconnect the alternator and
battery cables!
9. Spare parts must comply with the technical
requirements of the implement manufacturer. This

Hitching the Titan to the tractor
1. Whenthewagonisattachedthedistancebetweentop
edge of frame and ground must be 1.10 m. During
operation adjustments can be carried out as follows:
support wagon on support wheel so that pressure is
relieved from cylinder.
1.1 Release nut (1), screw out bolt (2), turn threaded
spindle with wrench (jaw size 32), screw bolt (2) back
in and counter with nut (1).
1.2 If required use the additional bore (3) in the drawbar
member.
1.3 For a drawbar without hydraulic cylinder release nut
(1),screwoutbolt(2).Useø8mmmandriltoturnturn
buckle(4). Screw bolt(2) back inand counter nut(1).
2. Always attach slip clutch at machine side. Adjust
lengthof universaldrive shaftto suit thetractor used.
Even with angled universal drive shaft (hydraulic
articulated drawbar) the minimum overlap of 14 cm
must be maintained.

Before starting
The following checks must be
carried out before the “TITAN”
cutting forage wagon is used:
1. All lubrication points and gear
units are provided with sufficient
oil or grease. But for reasons of
safety, all lubrication points and
gear units should be checked
and lubricated or topped up if
necessary.
2. Check that all lubrication points
accept grease and that all seals
are intact.
3. Check tightness of all nuts and bolts.
4. Test operation of vehicles with units switched on.
Listen for unusual noises.
5. After test operation check the machine once again.
If necessary tighten nuts and bolts and re-tension
chains.
6. Ensure that all guards are attached.
7. Do not lock the dry forage extension in vertical
position. If possible lock the extension struts angled
15° to the rear.
8. All TITAN are designed for a PTO shaft speed of
540 rpm.
Attention:
The tightness of the 10 special bolts on the large
chain wheel of the conveyor drum must be checked
at regular intervals, in particular after first use.
Tightening torque: 93 Nm
We recommend a PTO shaft speed of
400 – 500 rpm for fuel economy and smooth
operation.
9. If it is not necessary to fold down the dry forage
extension, the retaining screws of the steel profile
laths can be tightened securely. This provides the
box with additional stability and reduces noise on
uneven ground.
If it is often necessary to fold the box down (e.g.
low barn headroom) the screws must be released
sufficiently to allow the laths to move freely.

Universal drive shafts
Coupling the universal drive shaft
Clean PTO shafts of tractor and implement.
QS quick-locking mechanism
1. Pull sleeve back until it remains in open position.
2. Push universal drive shaft onto PTO shaft until QS
mechanism engages automatically. The sleeve mst
then rotate freely.
Sliding pin
3. Press sliding pin and at the same time push the
universal drive shaft onto the PTO shaft until the
sliding pin engages.
Pull lock
4. Pull the pull lock and at the same time push the
universal drive shaft onto the PTO shaft until the
lock engages.
QC lock
5. Turn locking ring and at the same time push the
universal drive shaft onto the PTO shaft until the
lock engages automatically.
6. Tighten screw over the clamping wedge (marking).
Always check that the universal drive shaft locking
devices are securely engaged before starting up.
Adjusting the universal drive shaft
Adjust the universal drive shaft to the tractor to obtain
the greatest possible overlap “LS” of the sliding profiles.
Important
Maximum overlap is determined in the tightest possible
cornering position. (Test both right and left.)
1. For length adjustment hold the drive shaft halves
beside each other in the shortest operating position.
2. Shorten inner and outer protective tubes equally.
3. Shorten inner and outer sliding profiles by the same
amount as the protective tube.
4. Smooth cut edges and remove swarf carefully.
Grease sliding profile.
Other alterations to the universal drive shaft and
protection are not permissible.
5. Attach arresting chains in such a way as to provide
sufficient slewing range for the universal drive shaft
in all operating positions.
6. Do not use arresting chains for suspending the
universal drive shaft.
Observe the operating instructions provided by the
universal drive shaft manufacturer.

Check slewing range and clearance for universal drive
shaft! Contact between universal drive shaft and tractor
or implement will cause damage (e.g. trailer equipment,
drawbar).
Overload couplings
Overload couplings protect tractor and implement from
damage. Therefore the guarantee is invalidated if the
set torque is altered by manipulation of the overload
safety device.
Attention! Compare the punched torque value (RM)
with the one in the table. If the values differ, please
contact your KRONE dealer.
The TITAN is equipped with a cam-type cut-out clutch
with a fixed torque value. If overloading occurs the
torque is interrupted. Full torque is then not available
until the PTO shaft has been switched off.
Always switch off the PTO shaft and the engine and remove the ignition key before cleaning,
lubricating or adjusting the PTO-driven implement or the universal drive shaft!
Ensure that no-one is in the danger area of the implement before switching the PTO shaft on.
Ensure that the PTO shaft speed selected at the tractor matches the permissible speed of the
implement before switching the PTO shaft on!

Putting the compressed air brake system
into operation (special equipment)
1. Connect “reservoir” (red) and “brake” (yellow) brake
hose coupling heads to the tractor. Ensure that the
hoses are positioned safely.
2. Method of operation and setting of the manually
adjustable pressure limiting valve (for vehicles with
compressedairbrakes withoutanti-wheel-lockbraking
system).
Pressure limiting valve
manually adjustable (braking force regulator)
Setting and method of operation
Thepressurelimitingvalvelimitsthepressureinthebrake
cylinders of trailers in relation to the load state. The valve
is located at the front on the left of the wagon.
The lever of the pressure limiting valve
mustbesetmanuallytooneofthepositions
“empty”, “half load” and “full load”,
depending on the load state of the trailer.
The lever must be moved to the position “release”
before manoeuvring the trailer when it is uncoupled and
braked. If the valve does not have a release position,
the release valve (1) is located on the brake valve itself,
which is located at the front on the left on the axle.
Secure the wagon against rolling away
before operating the release valve.
