1.1 Before using the implement
Figure 1.1
!Carefully read the instructions and make sure you understand their meaning.
!Always pay attention to the text and illustrations marked with this symbol!
!This implement is designed for preparing the soil in open fields. Learn to handle the implement
carefully and correctly!Drive carefully if there are rocks firmly embedded in the ground. The
implement can be dangerous in the wrong hands and operated carelessly.
1.2 Warning labels
Figure 1.2
A Carefully read the instructions and make sure you understand their meaning.
B All maintenance and service work should only be done when the implement has been lowered
to the ground. Never work under the implement during maintenance and service work unless
it has been properly secured using trestles or similar firm supports. Also be sure to block the
lifting ram of the transport wheels using the yellow locking devices (C). Secure the locking de-
vice using a cotter and locking pin.

1.3 Other safety precautions
!Prior to connecting the hydraulic hoses, be sure that the male couplings of the implement and
the femail couplings of the tractor are clear and free of dirt.
!The implement and its tyres are dimensioned for a maximum travel speed of
40 km/h during transport on the road. Please refer to ”1.3.1 Drive carefully! Always be safety
conscious!” on page 8.
The hydraulic ram operating the transport wheels can be secured for transport on the road using
the yellow locking device. See “Figure 1.3”.
!Prior to transport on public roads, remove dirt that may fall off from both the vehicle and the
implements.
!The owner/driver has sole responsibility for observing local traffic regulations when driving
on a public road.
!Always park the implement on a level and strong surface, and allow it to rest on the roller rings
and the supporting leg.
!Never stay close a the pressure hose under pressure. Be sure to recover any spilt oil during
work on the hydraulic system.
!If any work needs to be performed on the pre-implements, such as replacing tines, the imple-
ment should be secured by trestles or similar supports on firm ground.
!Pay attention during assembly or disassembly of weights. Be sure to secure them properly us-
ing locking pins and the threaded rod. See ”2.2.1 Fitting the weights (optional)” on page 16.
!To maintain the high level of quality and operational safety, use only Väderstad genuine spare
parts. The warranty and any complaint commitments will become void if other than genuine
parts are used.

1.3.1 Drive carefully! Always be safety conscious!
Figure 1.4
The implement is dimensioned for a maximum travel speed of 40 km/h during transport on the
road. To be able to drive at a speed of 40 km/h with this type of implement, the road surface must
be in excellent condition. The implement has a considerable unsuspended weight, which may
cause it to start jumping when travel un rough roads. Driving too fast on rough roads will put con-
siderable strain on the entire machine.
Slow down and adapt the speed if the road surface i uneven or in poor condition!
Damage incurred as a result of careless driving is not covered by the warranty.
Remember that the pushing load is considerable. Handling of the tractor is affected and the brak-
ing distance increases considerably.
You can never be in so much of a hurry that safety can be disregarded.

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 ma-
chine trailer or lorry flatbed!
The machine must be rolled onto and off the transport vehicle using a tractor. Lifting with a crane
is prohibited!
1 Raise the machine to the full lifting height.
2 Reverse the machine lengthwise onto the trailer or flatbed. If using a flatbed, a ramp, loading
pier or similar will be required. Take great care. Check that no machine parts are damaged
during loading.
3 Lower the compaction roller to the ground. Adjust the wheel carrier so that the transport wheels
also rest on the ground.
4 Adjust and secure the parking stay so that the machine rests on the parking stay, compaction
roller and transport wheels.
5 Secure the machine's transport wheels and compaction roller to prevent rolling using chocks
or similar.
6 Unhitch the tractor from the machine.
7 Secure the machine using suitable lashing equipment in accordance with applicable rules. The
lashing equipment must be attached to the machine at the locations indicated by the decals; see
“Figure 1.9”.
!For information on the machine's dimensions and weight, see ”5.2 Technical data” on page
26!
!Always make sure that you comply with applicable national regulations concerning transport
dimensions, requirements for escort vehicles or similar!

2 Assembly instructions
Never work under the implement during loading, unloading or installation work. Pay close atten-
tion to safety! The implement is very heavy.Only use lifting devices that have sufficient lifting
capacity. For weight indications, see ”5.2 Technical data” on page 26.
Depending on the transport method and other factors, the implement is delivered more or less as-
sembled from the factory. Use the instructions below that apply.
2.1 Loading and unloading
Figure 2.1
The implement is usually delivered with the tow connector and the preimplements packed on top
of the frame. The rear axle hydraulic ram has been removed and the rear axle has been moved for-
ward.
Lift the roller from the bed of the lorry using a fork lift. Use the transport support as shown in “Fig-
ure 2.1”.
