4.3 Safety Instructions and Accident Prevention Regulations
1 Please follow all generally applicable safety and accident prevention regulations in
addition to the safety instructions contained in these operating instructions!
2 The attached warning and safety signs provide important information for safe operation.
Pay attention to these for your own safety!
3 When using public roads, make sure to observe the applicable traffic regulations!
4 Make sure that you are familiar with all equipment and controls as well as with their
functions before you begin working with the machine. It is too late to learn this when you
are using the machine for work!
5 The user should wear close fitting clothes. Avoid wearing loose or baggy clothing.
6 Keep the machine clean to prevent the danger of fire!
7 Before starting or moving the machine, make certain that nobody is in the vicinity of the
machine! (Watch for children!) Make sure that you have a clear view!
8 Carrying passengers during operation and transport on the working implement is not
permitted.
9 Couple implements correctly! Attach and secure implements to specified devices only!
10 When attaching or detaching implements, place the supporting devices in the correct
positions!
11 Use extreme caution when attaching or detaching implements onto or from the tractor!
12 Always attach ballast weights properly to the fixing points provided!
13 Observe permitted axle loads, gross weight and transport dimensions!
14 Check and attach transport equipment, such as lighting, warning devices and protective
equipment!
15 Actuating mechanisms (cables, chains, linkages etc.) for remote controlled devices must
be positioned in such a way that no movements are unintentionally triggered in any
transport or working positions.
16 Ensure that implements are in the prescribed condition for on-road travel and lock them in
place in accordance with the manufacturer's instructions!
17 Never leave the driver's seat when the vehicle is moving!
18 Always drive at the correct speed for the prevailing driving conditions! Avoid sudden
changes in direction when travelling uphill or downhill or across a gradient!
19 Hitched implements and ballast weights affect the driving, steering and braking response
of the machine. Make sure that you are able to brake and steer the machine as required!
20 Take into account the extension radius and/or inertia of an implement when turning
corners!
21 Start up implements only when all safety devices have been attached and set in the
required position!
22 Keep safety equipment in good condition. Replace missing or damaged parts.
23 Keep clear of the working range of the machine at all times!
24 Do not stand within the turning and swivel range of the implement!
25 Never operate the hydraulic folding frames if anyone is inside the swivel range!

Safety
14
26 Parts operated by external power (e.g. hydraulically) can cause crushing and shearing
injuries!
27 Before leaving the tractor, lower the implement onto the ground, apply the parking brake,
switch off the engine and remove the ignition key!

4.4 Attached devices
1 Use extreme caution when attaching or detaching implements onto or from the tractor!
2 Couple the respective application devices to the appropriate couplings (e.g. three-point
suspension) only and secure them in a way (transport, use) that excludes inadvertent
lifting or lowering of the device.
3 When using three-point linkage, the attachment categories of the tractor and the device
(e.g. PTO speed, hydraulic system) must be coordinated!
4 When using the outside controls for the three-point linkage, do not step between the
tractor and the device (risk of injury)!

4.5 PTO operation
1Use only PTO shafts specified by the manufacturer!
2The guard tube and guard cone of the PTO shaft and the PTO guard must be attached
and in good working condition (on the implement side, too)!
3Make sure that the required tube covers are in place for PTO shafts in transport and
working position!
4Before installing or detaching PTO shafts, disengage the PTO, switch off the engine and
remove the ignition key!
5When using PTO shafts with an overload safety or free-running coupling which are not
shielded by the guard on the tractor, mount the overload safety or free-running coupling
on the implement side!
6Always make sure that the PTO shaft is properly installed and secured!
7Attach chains to prevent the PTO shaft guard from rotating with the shaft!
8Before switching on the PTO, make sure that the selected PTO speed of the tractor
matches the permissible implement speed!
9Before switching on the PTO shaft make sure that no person is in the danger zone of the
device!
10Never switch on the PTO if the engine is switched off!
11No one should be in the vicinity of the rotating PTO or PTO shaft when the PTO is in use.
12Always switch off the PTO shaft when the angle is too large or the PTO shaft is not
required!
13Caution! After disengaging the PTO danger due to the flywheel running on! Keep away
from the implement during this time. The machine may be worked on only if it is
completely at standstill and if the flywheel is secured by the parking brake.
14Cleaning, lubricating or adjusting PTO driven implements or the PTO shaft only with PTO
disengaged, engine switched off and ignition key withdrawn! Secure the fly-wheel with the
parking brake.
15Place the disconnected PTO shaft onto the support provided!
16After detaching the PTO shaft, attach the protective cover to the PTO end!
17If damage occurs, correct this immediately before using the implement!

4.6 Hydraulic system
1The hydraulic system is pressurised!
2When connecting hydraulic cylinders and motors, make sure the hydraulic hoses are
connected as specified!
3When connecting the hydraulic hoses to the tractor hydraulics, make sure that the
hydraulics of both the tractor and the implement have been depressurized!
4In the case of hydraulic connections between tractor and machine, the coupling sleeves
and plugs should be marked to ensure a proper connection! If the connectors are
interchanged, the function will be reversed (e. g. raising/lowering) - Risk of accident!
5When searching for leaks, use suitable aids to avoid the risk of injury!
6Liquids escaping under high pressure (hydraulic oil) can penetrate the skin and cause
serious injury! Seek medical help immediately should injuries occur! Danger of infection!
7Before working on the hydraulic system, depressurise the system and switch off the
engine!

8 Check the hydraulic hose lines at regular intervals and replace them if damaged or worn!
The new hoses must fulfill the technical requirements set by the manufacturer of the
implement!

4.7 Tyres
Pos: 13.6.14 /BA/Sicherh eit/Reifen @ 0\mod_119564 6435716_78.docx @ 1346 @ @ 1 1When working on the tyres, make sure that the implement is safely lowered and secured
against rolling (wheel chocks).
2Installing wheels and tyres requires adequate knowledge and suitable tools!
3Repair work on the tyres and wheels should be done by specially trained personnel using
appropriate installation tools only!
4Check tyre pressure regularly! Inflate the tyres to the recommended pressures!
5Check the wheel nuts periodically! Missing wheel nuts can result in a wheel falling off and
the machine tipping over.

4.8 Maintenance
1 Always make certain that the drive and the engine are switched off before doing any
repairs, maintenance or cleaning! - Remove the ignition key!
2 Regularly check that nuts and bolts are properly seated and tighten if necessary!
3 When carrying out maintenance work on a raised mowing unit, always use suitable
means to secure it against falling.
4 When replacing working tools with cutting edges, use suitable tools and gloves!
5 Oils, greases and filters must be disposed of correctly!
6 Always disconnect the power supply before working on the electrical system!
7 If protective devices and guards are subject to wear, check them regularly and replace
them in good time!
8 When performing electrical welding work on the vehicle and mounted devices, turn the
power supply off at main battery switch or disconnect generator cable and battery!
9 Replacement parts must at least comply with the technical requirements set by the
manufacturer of the implements! This is guaranteed by original KRONE spare parts!
10 Only use nitrogen for filling pneumatic accumulators - risk of explosion!

4.11 Introduction
The disc mower is equipped with all safety devices (protective devices). However, it is not
possible to eliminate all potential hazards on this machine as this would impair its full functional
capability. Hazard warnings are attached to the machine in the relevant areas to warn against
any dangers. The safety instructions are provided in the form of so-called warning pictograms.
Important information on the position of these safety signs and what they mean is given below!
