1.3 Other safety regulations
!VERY IMPORTANT! Retighten screw connections according to the table. See “1.4 Retight-
ening of screw connections” see page 11 .
• As the implement is heavy, front counterweights should normally be mounted on the tractor.
Always ensure that the tractor has a sufficient load on the front axle for safe driving.
Figure 1.4
• Take great care when dismantling the cultivator tines’ springs! They have a very large inherent
spring force. See “4.6 Dismantling the parts in the cultivator tine suspension system” see page
35 .
• Check that the tractor’s tyres and wheels are adapted for the weight of the implement and that
the air pressure in the tyres is correct. Note that there is a high load on the tractor’s rear axle,
particularly during road transport. It is therefore necessary to check that the maximum permit-
ted axle load is not exceeded. The implement’s hitching weight on the tractor is indicated in
“6 Technical data” see page 38 .
• Prior to transport on public roads, remove dirt that may fall off from both the tractor and im-
plement.
• Observe great caution when transporting the implement on public roads. Pay attention to the
width and turning area of the implement during transport. Check the position of the tractor
rearview mirrors. Also check that the tractor’s slow vehicle sign is visible above the imple-
ment. The owner/operator is solely responsible for transport of the implement on public roads.
• Prior to transport, fold in the levelling unit’s outer discs in order to reduce the transport width
to less than 3.0, 3.5 and 4 metres respectively.
• Use the lights on the implement in accordance with local traffic regulations.
• Keep in mind that the implement is heavy and, as a result, the braking distance is longer.
• Trailed cultivators may be transported at a maximum speed of 25 km/h on public highways.
When transporting on uneven roads, the transport speed should be reduced.
• When transporting trailed cultivators, all the spacers must be mounted on the ram rod.
• Note that the owner/operator has sole responsibility for complying with national traffic regu-
lations when driving on public roads.
• Prior to connecting the hydraulic hoses, make sure the male couplings on the implement and
the female connectors on the tractor are clean and free from dirt.
• Always use Väderstad original spare parts to maintain the quality and reliability of the imple-
ment. If other makes of spare parts are used, all guarantee and claims commitments cease to be
valid.
• Never dismantle a roller ring unit with steel rings. The unit has been pressed together with a
force of 4 tonnes and there is a high risk of injury if attempts are made to disassemble the unit.
If there should ever be a need for disassembly, please contact the dealer as special tools are
required.

Safety regulations

• Any welding work on the machine should maintain a professional standard.
Incorrect welding may result in serious injuries or possibly fatal injuries. If in doubt, contact a
professional welding service for proper instructions.
• Never stand under the implement if it is only secured with the tractor’s three-point lift! The
section “4.1 Securing implement during service, hydraulically mounted” see page 31 shows
how the implement is to be supported.
• Do not stand near hydraulic hoses under pressure. Recover any spilled oil after performing
service on the hydraulic system.
• Before driving off, make sure that all screws and nuts are tight.
• Always park the implement on a level and solid surface. Depressurise the implement’s hydrau-
lic system, if present, by using the float position on the tractor’s hydraulic control. The imple-
ment then rests on tines and the compaction roller.

1.4 Retightening of screw connections
Figure 1.5
!Retighten the screw connections (A) between drawbar and chassis after the first day of opera-
tion. Tighten the screw connections to a torque of 550 Nm. Use a torque wrench.
!The screw connections (B) in the cultivator tine linkage must be retightened after the first day
of operation and thereafter at least once per season. Tighten the screw connections to a torque
of 114 Nm. Use a torque wrench. See also “4.5 Retightening and checking the tine linkage”
see page 34 .
1.4.1 Explanation of tightening torque

1.6 Moving the machine when not hitched to a tractor
NOTE!If the machine must be moved when not hitched to a tractor,it must be transported on a
machine trailer or lorry flatbed!
Mounted machines must be lifted onto and off the transport vehicle using a crane, whilst semi-
mounted machines must be rolled onto and off the transport vehicle using a tractor. Semi-mounted
machines must not be lifted by crane!
1.6.1 Lifting on and off of mounted CS 300-350
1 Place the machine on level ground and adjust the depth setting stay, so that it rests against the
tines and compaction roller. Add as many clips as there is space for on the stay.
2 Unhitch the tractor from the machine.
3 Lift the machine on or off using a suitable lifting device at the lifting points indicated by the
decals; see “Figure 1.8”.
!For information on the machine's dimensions and weight, see “6 Technical data” see page 38 .

2 Instructions and settings
2.1 Tractor
!The CS 300-350 is intended for tractors up to 160 hp (118 kW). The CS 400 is intended for
tractors up to 200 hp (147 kW). The use of tractors with higher outputs can result in more rapid
wear of the implement.
• To reduce soil compaction and to increase the pull, the tractor should be fitted with very good
tyres.
• Check that the tractor’s tyres are adapted for the weight of the implement and that the air pres-
sure in the tyres is correct. Note that there is a high load on the tractor’s rear axle, particularly
during road transport. It is therefore necessary to check that the maximum permitted axle load
is not exceeded.
A double-acting hydraulic coupling is required in the case of trailed machines.

2.2 Hitching and unhitching the implement
Figure 2.1
2.2.1 Hitching
Hitch the implement to the tractor and connect any hydraulic hoses. Do not standbetween the trac-
tor and the implement when the tractor is being reversed to hitch the implement!
2.2.2 Unhitching
When unhitching the machine, it is important to ensure that all the tines have roughly the same
load in order to avoid the tips being broken off.
7 Lower the implement onto a flat, stable surface. The implement rests on the tips of the tines
and the compaction roller.
8 Disconnect the three-point couplings.
Trailed machine with all supplied clips on the ram rod as a traffic safety catch must first be raised
to full lifting height. This is done to remove the clips so that the machine can be parallel with the
ground. It is important to ensure that all the tines have roughly the same load in order to avoid the
tips being broken off.
1 Lower the implement onto a flat, stable surface.
2 Depressurise the implement’s hydraulic system by using the float position on the tractor’s hy-
draulic control. The implement then rests on the tips of the tines and the compaction roller.
3 Disconnect the hydraulic hoses and the three-point connections.

ver.3 17
2.2.3 Choice of coupling points
Figure 2.2
The implement is adapted for a category II or III three-point coupling.
In order to minimise the lifting power requirement, the top rod should be mounted in a high cou-
pling point on the tractor and a low coupling point on the implement.
The round hole (A) is used if you want to use the length of the top rod to adjust the height of the
front part of the implement. When using this coupling point, the tractor’s hydraulic lifting arms
must be in the float position when operating in the field.
The oval hole (B) is used if you want to adjust the height of the front part of the implement using
the hydraulic lifting arms’ height setting. Adjust the length of the top rod so that the pin is in the
middle of the oval hole when the implement is parallel with the ground. Then fine-adjust using the
height position of the hydraulic lifting arms when operating in the field.
NOTE!During installation, always use the enclosed original pin.
NOTE!On rolling fields, you are always recommended to use the oblong hole for more gentle han-
dling of the implement.
NOTE!The front hole (C) must only be used for installing the drawbar.

2.3 Setting the levelling units
Figure 2.4
The height of the levelling units is adjusted using a crank handle. The crank handle has two alter-
native mounting points in the levelling units, so that optimum height adjustment should always be
possible.
The levelling unit must be adjusted so that the soil cover behind the implement is as even as pos-
sible. As the levelling unit is mounted on the compaction roller’s chassis, the setting of the level-
ling unit does not need to be adjusted in the event of minor changes in the working depth.
NOTE!The work results of the levelling units are usually best if they are set in a relatively shallow
position. If the levelling units are wound down to a depth that is too great, this may cause the op-
posite effect, i.e. an uneven ground surface behind the implement.

2.3.1 Adjustable outer levelling discs
Figure 2.6
Individually adjustable levelling discs can be found outermost on either side. These enable opti-
mum levelling in the corridors between each driven pass. Depending on working depth, soil type,
etc., it may be appropriate to perform adjustment to avoid the formation of trailing lea lines or fur-
rows.
In order to adjust, loosen screws (A) and move the discs along the oval holes. To allow more flex-
ible adjustment settings, the screw connections can also be moved to two alternative height posi-
tions.
The entire levelling unit can be moved along the shaft to optimise the function. Unscrew the nuts
until they almost come apart from the carriage bolt. Using mild force, the entire unit can then be
moved in the desired direction along the shaft.
2.3.2 Folding outer levelling discs
Figure 2.7
The outer levelling discs can be folded in so that the implement’s transport width does not exceed
3.0, 3.5 or 4.0 metres respectively.
When resetting to the folded position, the shafts are folded up and secured with the pins in pos.
(A).
In the folded out position, flexible links are always recommended with the pins stored in pos. (B).

2.4 Adjusting the working depth of the tines, hydraulically
mounted
Figure 2.8
Figure 2.9
The working depth of the tines is determined by the setting of the compaction roller. The compac-
tion roller is adjusted with the aid of a rod (A). The rod can be supplied with clips (B) to secure
the end position. In order to mount the clips, the machine must first be raised in the hydraulic lift-
ing arms. The more clips are mounted, the shallower the working depth.
!Note that the parallel alignment of the implement is affected when altering the working depth.
