CRX 425-625 Safety rules Before using the implement Figure 1.1 ! Carefully read the instructions and make sure you understand their implications. ! Always pay special attention to the text or illustration indicated by this symbol! ! Learn to handle the implement carefully and correctly! In the wrong hands or if operated care- lessly, the implement can be dangerous.
Safety rules Warning decals CRX 425-625 CRX 625 Figure 1.2 Carefully read the instructions and make sure you understand their implications. Do not stand between the tractor and the implement when the tractor is reversed and the im- plement hitched. Make sure that the working area and folding area of the implement are completely clear.
Safety rules Other rules governing safety Figure 1.4 ! Because the implement is heavy, front weights should be fitted to the tractor in most instances. Always ensure that the front axle of the tractor is sufficiently loaded to allow it to be driven safely.
CRX 425-625 ! Never dismantle a roller unit with steel rings. The unit has been pressed together with a force of 4 tons, which constitutes a major risk of personal injury should an attempt be made to dis- mantle it. If you should need to dismantle the unit at any time, contact your dealer as special tools are required for the procedure.
Safety rules Moving the implement without connecting it to a trac- NOTE! If the implement must be moved without it being hitched to a tractor, it must be carried on a machine trailer or truck flatbed! The implement must be extended to working mode and lifted on and off the transport vehicle using a crane.
CRX 425-625 Instructions and settings Tractor Figure 2.1 Due to the weight of the implement, it is important that a tractor of sufficient size and weight is used! ! In most cases, front weights should be attached to the tractor. Always ensure that the front axle of the tractor is sufficiently loaded to allow it to be driven safely! ! Check that the tractor's tyre set up has been adapted to cope with the weight of the implement and that the tyres are inflated to the correct pressure.
Instructions and settings Connecting the implement Figure 2.2 1 Connect the implement to the three point coupling on the tractor, see “2.4 Selecting hitching points” on page 19. Do not stand between the tractor and the implement when the tractor is reversed and the implement hitched! 2 Connect the hydraulic hoses.
CRX 425-625 Unhitching and parking implement 2.3.1 Unhitching and parking the implement in transport mode Figure 2.3 NOTE! The implement may only be parked in transport mode on a flat and stable surface! If this is not possible, the implement must instead be parked in working mode. See “2.3.2 Unhitching and parking the implement in working mode”...

Instructions and settings 2.3.2 Unhitching and parking the implement in working mode Figure 2.4 1 Lower the implement, set to working mode, on to the base so that it stands on its discs and roll- 2 Set the working depth of the front tool so that the implement is standing parallel. Surface (A) must be parallel to the base.
CRX 425-625 Selecting hitching points Figure 2.5 The implement is designed for category III three-point hitching. 2.4.1 Hitching point for top link In order to minimise the lifting force required, the top link should be fitted to a high hitching point on the tractor and a low hitching point on the implement.
Page 20
Instructions and settings 2.4.2 Hitching point for hydraulic arms Low hitching point Figure 2.6 A low hitching point provides a good lifting height in areas where there are features such as turn strips. A low hitching point distributes a significant proportion of the weight to the tractor and reduces the working weight of the implement.

CRX 425-625 2.4.3 Stabiliser rods on tractor hydraulic arms Figure 2.8 ! When driving in fields and during transport, the stabiliser rods for the tractor's hydraulic arms should be locked. 01.05.2015 1...
Instructions and settings Switching to working mode 1 Lift the implement using the hydraulic arms. The implement must be lifted to a height that is sufficient to allow folding to be done unhindered! 2 Pull the wing sections together using the hydraulic system. 3 Release the locking catches for both wing sections.
CRX 425-625 Switching to transport mode 1 Lift the implement using the hydraulic arms. The implement must be lifted to a height that is sufficient to allow folding to be done unhindered! 2 Fold in the wing sections using the hydraulic system. 3 Check that both wing sections are secured in position by the lock hooks.
Instructions and settings Setting wing section horizontal alignment Max 45 mm Figure 2.13 The horizontal alignment of the wing sections must be set so that an even working depth and level of compacting is achieved. This setting is done by adjusting the wing folding ram piston rods. NOTE! This is a two-stage process - basic setting and final adjustment.
Page 25
CRX 425-625 Max 45 mm Figure 2.14 Final adjustment In order to achieve the best results during field driving, the wing sections should be set so that there is a slight downhang when they are in raised position. ! In order to make final adjustments, the wing sections must be in their default parallel alignment setting, see“...
Instructions and settings Adjusting scrapers, steel compactors The scrapers should be fitted as far in between the roller rings as possible. If the pins are worn, they can be adjusted by moving the scraper beam. Figure 2.15 Adjusting scrapers, rubber compactors Approx.
CRX 425-625 2.10 Setting implement parallel alignment Figure 2.17 The parallel alignment of the implement is adjusted using either the length of the top rod or the height position of the hydraulic arms, depending on which hitching point has been selected in the implement tower, see “2.4 Selecting hitching points”...
Instructions and settings 2.11 Setting disc working depth Figure 2.18 Disc working depth is regulated by two hydraulic cylinders connected in series. These cylinders must be bled before the implement is used. ! Bleed the cylinders as described in “4.11 Bleeding the hydraulic system to set disc front tool” on page 39.
Page 29
CRX 425-625 2.11.1 Mechanical depth stopper. Figure 2.20 The implement is also equipped with a mechanical depth stopper. By fitting spacers to the piston rod on one of the hydraulic cylinders, you limit stroke length and thereby maximum working depth. The working depth can now be regulated during operation to the extent permitted by the new stroke length.
Instructions and settings 2.12 Adjusting the height of outer discs Figure 2.21 To prevent the implement from leaving trailing lea lines, the height and lateral direction of the out- ermost disc on each side can be adjusted. Choose a setting that suits the working depth, soil type, etc.
CRX 425-625 Driving instructions Direction of travel Figure 3.1 1 The first run should be made immediately after harvesting and at 20° - 40° to the direction of threshing. 2 The second run should be made at 20° - 40° to the previous run. The final run before drilling must not be made in the direction in which drilling is intended to take place.
Service and maintenance Service and maintenance Figure 4.1 Securing the implement for service ! Do not go under the implement if it is only secured in position by the tractor's three point lift! 1 Fold out the implement to the work position. 2 Lower the implement so that the roller rests on a stable base.
CRX 425-625 General during servicing ! Do not stand near hydraulic hoses under pressure. Recover any spilled oil after performing ser- vice on the hydraulic system. ! Always use genuine Väderstad spare parts to maintain the quality and reliability of the imple- ment.

CRX 425-625 Check of wing folding ram piston rod heads B=Max 45 mm Figure 4.4 Check that the lock nuts (A) to the wing folding ram piston rod heads are tightened at least once per season. If the lock nuts come loose, there is a danger that the ram pipes will rotate, changing the stroke length of the cylinders.
Service and maintenance Changing discs Make sure the implement rests properly on solid supports. When replacing discs, use a ratchet wrench or better still a nutrunner. Block the disc using a wood block or similar to prevent it from turning. The discs have sharp edges - use gloves! Tighten the pinned head screws crosswise to a torque of 105 Nm.
CRX 425-625 Replacing the ram seal in the hydraulic ram used for folding NOTE! Take great care. The hydraulic ram for folding may be pressurised even if the implement is not connected to the tractor. Figure 4.6 NOTE! The piston rod guide is tightened to 700 Nm and fitted with a mechanical rotation lock. NOTE! Clean the hydraulic ram thoroughly before starting work.
Service and maintenance Replacing ram seal in the hydraulic ram for setting disc working depth Figure 4.7 Unscrew and remove the piston rod guide (A) using the hook wrench (B). Pull out the piston rod. The seal can now be replaced. NOTE! Make sure that the seals face the correct way.
CRX 425-625 Bleeding the accumulator and hydraulic pressure be- fore servicing the hydraulic system The implement must be connected to a tractor, folded out into working position and resting on a flat and stable surface. Make sure that the machine's working area is clear so that no-one is under or in the vicinity of the machine whilst its hydraulics are operated in accordance with the points set out below.
Service and maintenance 4.12 Replacing the roller assembly Figure 4.8 NOTE! The implement must be connected to the tractor's three point hitch for the entire procedure! Use a tractor with sufficient weight, ideally the tractor intended to pull the implement when work- ing.
CRX 425-625 4.13 Roller unit servicing, steel compactor Figure 4.9 Other than greasing bearings, roller units do not usually require any maintenance. Roller units fea- ture auto tensioners. NOTE! Never dismantle a steel ring unit. The unit has been pressed together with a force of 4 tons, which constitutes a major risk of personal injury should an attempt be made to dismantle it.
Service and maintenance 4.16 Lifting using a crane If the implement is to be lifted using a crane, the choice of lifting points must be a considered one. If the implement is in working mode, lifting must be done from the centre section. If the imple- ment is in transport mode, it must be lifted from the wing sections.
