The adherence to the instructions in this chapter is a prerequisite for the safe han- dling and trouble-free operation of the machine.
Page 12
Safety Warning severity level The degree of danger is indicated by the signal word. The levels are classified as follows: n DANGER Type and source of danger This warning warns of a danger posing an immediate threat to the health and life of persons. Ignoring these warnings will result in very serious or even fatal injury.
Safety General information on the safety of the machine The machine is constructed in accordance with the state of the art and the recog- nized technical regulations. However, its usage and maintenance may cause danger to the health and life of the operator or third parties and/or the impairment of the machine and other material assets.
Safety 3.4.3 Accident prevention Safety and accident prevention regulations are governed by law in every country. The operator of the machine shall be responsible for the compliance with these regulations applicable in the country of use. The following instructions must also be observed: Never let the machine run without supervision.
Safety 3.5.3 Filling the machine Only fill the machine when the motor of the tractor is stopped. Remove the ignition key in order to ensure that the motor cannot be started. Use suitable auxiliary equipment for filling the spreader (e.g. front-end loader, ...
Safety 3.5.5 Hazard zone Ejected spreading material may lead to severe injury (e. g. to eyes). When persons are present between the tractor and the machine, there is a great hazard caused by the tractor rolling away or by machine movements which may have fatal consequences.
Safety 3.5.6 Operation If the machine malfunctions, stop the machine immediately and secure it. Have the fault repaired immediately by appropriately instructed and author- ised personnel. Never climb onto the machine while the spreader unit is running. Only operate the machine with the protective grid in the hopper. The protec- ...

When selecting the spreading material, inform yourself about its effects on persons, the environment, and the machine. Follow the directions of the spreading material manufacturer exactly. ...
Safety Maintenance and service Maintenance and service work involves additional hazards that do not occur dur- ing operation of the machine. Any maintenance and service work is to be conducted with increased alert- ness at all times. Work particularly thoroughly and cautiously. 3.8.1 Qualifications of maintenance staff Welding and work on the electrical and hydraulic systems is to be carried out...
Safety Remove any clogging in the hopper only when the machine stands still and never use your hand or foot to do it; always use suitable tools for this purpose. In order to avoid clogging, the hopper may only be filled when the protective grid is mounted.
Safety 3.9.2 Using the machine for transport The handling, tilting, steering, and braking performance of the tractor is affected by the attached machine. For example, the high load will reduce the weight on the tractor's front axle and affect its steering. Be aware of the changed driving behaviour.

Machine settings 7.5.2 Implementing the calibration test n WARNING Risk of injury due to chemicals Discharged spreading material may cause injury to eyes and nasal mucous membranes. Wear protective goggles during the calibration test. Before running the calibration test, ensure that all people leave the hazard zone of the machine.
Page 61
Machine settings 6. Activate the tractor and the drive of the machine. 7. Open the metering slide for the calibration test time stipulated before (e.g. 60 seconds). Close the metering slide when this time has elapsed. 8. Deactivate the drive of the machine and the tractor. Remove the ignition key. 9.
Spreading work Spreading work General information The modern technology and design of the machine and exhaustive, continuous testing in the factory's spreading material test facilities ensure that you will have a perfect spreading pattern. Our machines are manufactured with utmost diligence. However, deviations in the application rate or possible faults cannot be excluded, even when complying with the intended use.
Spreading work Select the PTO speed and/or the spreading disc speed in a way that the desired spreading width can be achieved and no deposits form on the spreading disc. A low PTO speed/spreading disc speed reduces the wear on the agitator and spreading disc.
Spreading work Instructions regarding the spreading operation The intended use of the machine includes compliance with the operating, main- tenance, and service conditions in accordance with the manufacturer specifica- tions. Spreading operation therefore always includes preparation and cleaning/maintenance. n DANGER Danger of injury when spreading Contact with rotating machine components (universal drive shaft, spreading disc, agitator) may cause injury.
Spreading work Spreading grit or granular fertiliser n WARNING Risk of injury caused by spreading material Ejected spreading material may lead to injuries. Ensure that nobody is present in the hazard zone. When spreading of grit or granular fertiliser, observe the following: Use the RWK 8 agitator.
Spreading work Spreading sand, salt or sand-salt mixtures n WARNING Risk of injury caused by spreading material Ejected spreading material may lead to injuries. Ensure that nobody is present in the hazard zone. For spreading sand, salt or a sand-salt mixture, observe the following: Use the RWK 10 agitator.
Spreading work Discharging residual material We recommend emptying the machine immediately after every use to maintain its value and to ensure a fault-free spreading operation. 1. Deactivate the drive and switch off the tractor motor. 2. For collecting the spreading material, place a foil under the machine or posi- tion a sufficiently sized hopper beneath the outlet.
Spare parts must at least comply with the technical standards specified by the manufacturer. This is assured e. g. with RAUCH original spare parts. Before starting any cleaning, maintenance, or repair work, and when trouble- ...

Maintenance and service Checking the agitator for wear 9.4.1 Dismounting the agitator The agitator is fixed with a bayonet lock. 1. Open the hex cap screw at the protective grid in the hopper. 2. Remove the protective grid. 3. Turn the agitator clockwise until it reaches the stop.
Maintenance and service 9.4.2 Checking the RWK 8 agitator for wear Check the agitator for dam- age and wear. Figure 9.3: RWK 8 agitator 9.4.3 Checking the RWK 10 agitator for wear If the spreading material no longer flows equally out of the metering opening, re- place the agitator finger.
Maintenance and service Check the universal joint [2] for free movement. Check the agitator finger [3] for damage and wear. Excessively worn agitator fingers can break and must be replaced. The agitator finger must not be bent. Replacing the spreader vanes Worn spreader vanes can be replaced.
Maintenance and service 1. Loosen the self-locking nuts at the spreading vane and take them off the spreading vane. 2. Install the new spreading vane onto the spreading disc. Make sure you use the correct spreading vane type. Figure 9.6: Use new self-locking nuts 3.
