Installation 4 Installation 4.1 Transport The device is delivered on a transport pallet with a wooden cover. We recommend using a forklift or pallet truck for transporting the packed device. DANGER! Do not step under the transport pallet during transport. WARNING! Improper lifting can lead to personal injury or property damage. The machine is only to be lifted with suitable equipment and by qualified personnel. The guarantee excludes all claims for damage due to improper transport. 4.
Installation CAUTION! Ensure that the device is safely fastened. Considerable lateral forces can occur! CAUTION! The weight of the cutting mill is approx. 42 kg with cutting tools. NOTICE! Place the cutting mill on a flat, stable surface. It may be screwed to this or a base plate. NOTICE! – Make sure that the cutting mill is easily accessible. On the right of the mill, there must be enough space to open the upper part of the housing together with the funnel.
Installation 4.4 Ambient conditions WARNING! Mains voltage! – The device may only be operated indoors. – The surrounding air may not carry any electrically conductive dust. – Maximum relative humidity 80% for temperatures up to 31°C, linearly decreasing down to 50% relative humidity at 40°C. n The room temperature has to stay between 5 - 40°C. n Altitudes up to 2000 m n Degree of pollution 2 according to IEC 664. 4.
Initial start-up 5 Initial start-up After the PULVERISETTE 15 has been set up as described in Ä ‘Installa‐ tion’ on page 17 and the mains plug has been plugged into the mains socket, the device is ready for operation. Check whether the rotor can turn freely before switching on for the first time. To do so, open the closing lid and turn the rotor one complete rotation by hand with the upper part closed. If the rotor can turn freely, the closing lid can be closed again. If not, check the cutting gap.
Using the device 6 Using the device WARNING! If the grinding elements used are not original accessories, we provide no guarantee and exclude all liability for damage to the device. 6.1 Preparing a comminution 6.1.1 Opening the cutting mill 1. Turning the handle on the closing lid (4) to the left unlocks the lid. 2. Open the closing lid. When open, the closing lid can be lifted upward out of the hinges. 3. Unscrew the screw in order to open the upper half of the housing to the right side.
Using the device 6.1.2 Inserting the bottom sieve CAUTION! Risk of injury due to sharp knives. CAUTION! Risk of injury! Beware of the sharp edges of the rotor and the fixed knives! Wear protective gloves when inserting the sieve, the fixed knives and the rotor! 1. Open the closing lid to insert the sieve. 2. Push the sieve from the front under the left and right fixed knives. Or take off the closing lid, open the upper part of the housing and then insert the sieve.
Using the device 6.1.3 Checking the gap width The rotating knives must not touch the fixed knives. A cutting gap of 0.2 0.3 mm has been set between them at the factory. The rotating knives must be aligned parallel to the fixed knives. Turn the cutting rotor carefully by hand. If the rotating knives are badly worn, it is possible to turn them over once. See Ä ‘Setting the gap width’ on page 23. 6.1.3.1 Setting the gap width Set the gap width as follows: 1. Open the closing lid. 2.
Using the device 10. Repeat the procedure for the third fixed knife. Make sure the fixed knives are parallel. If they are not par‐ allel, the fixed knives have to be realigned using the pres‐ sure screws. 6.1.4 Closing the cutting mill Before closing the closing lid, please observe the following: n Check whether the cutting rotor and sieve are securely fitted. n Clean the conical guide on the cutting rotor. n Clean the conical guide in the closing lid.
Using the device 5. Open the funnel lid, add some comminution material and close the lid again. The sample quantity varies depending on the particle feed size, the hardness of the material and the sieve size. It is best to start with small quantities and increase them depending on the success of the com‐ minution. 6. Close the funnel lid and pull the plunger slowly upward. ð This causes the material to be cut to fall into the cutting chamber. 7. Lower the plunger slowly.
Using the device 6.3 Comminution procedure with the funnel for long and bulk solids CAUTION! Wear safety goggles for comminution using the funnel for long and bulk solids! There is a risk of particles from the funnel being projected, in the case of free-flowing material. 1. Close the cutting mill. 2. Attach the collecting vessel. 3. Switch on the device. 4. Add some comminution material and pull the plunger slowly upward. The material to be cut falls into the cutting chamber.
Accessories 7 Accessories 7.1 Filter hose and collecting vessel Using a fabric filter hose between the PULVERISETTE 15 and the collecting vessel allows the air flow created by the rotating rotor to be exhausted and prevents a backup. Furthermore, it accelerates the material throughput and guarantees a gentle comminution process. n Clamp the adapter with the sieve to the device using the toggle latches. n Pull the filter hose over the sieve.
Cleaning 8 Cleaning DANGER! Mains voltage! – Before beginning with cleaning work, disconnect the mains plug and protect the device against being unintentionally switched back on! – Do not allow any liquids to flow into the device. – Indicate cleaning work with warning signs. – Put safety equipment back into operation after cleaning work. CAUTION! Risk of injury due to sharp knives. The housing of the cutting mill can be rubbed down with a damp cloth. 8.
Maintenance 9 Maintenance DANGER! Mains voltage – Before beginning with maintenance work, unplug the mains plug and protect the device against being unintentionally switched back on again! – Indicate maintenance work with warning signs. – Maintenance work may only be performed by specialised personnel. – Put safety equipment back into operation after maintenance or repair work We recommend keeping a safety logbook Ä Chapter 13 ‘Safety logbook’ on page 39, where all work (maintenance, repairs......

Caution! If the switch is defective, the rotor will start up.
Maintenance 9.1.1 Assembling the rotating knives NOTICE! In order to turn or install the rotating knives, all 3 fixed knives have to be pushed toward the exterior, and then the gap has to be redefined. (see Ä ‘Assembling the rotating knives’ on page 31 and Ä ‘Setting the gap width’ on page 23) To remove the rotating knives, proceed as follows: 1. Open the closing lid. 2. Open the upper half of the device. 3. The rotating knives are then completely accessible.
Maintenance 1. Open the closing lid. 2. Position the rotating knife with the smallest gap by pushing it in the direction of the left fixed knife until the knives are edge-toedge. 3. Mark the rotating knife which was used for this purpose. 4. Unscrew the middle retaining screws of the knives on the exterior of the housing. 5. Pull the knives out. 6. Unscrew the pressure screws completely. 7. Position the new fixed knives.
Maintenance NOTICE! After setting the fixed knives, always tighten the retaining screws firmly. Make sure the fixed knives are parallel. If they are not par‐ allel, the fixed knives have to be realigned using the pres‐ sure screws. 9.1.3 Removing the rotor To remove the rotor, proceed as follows: 1. Open the closing lid. To fasten the rotor, wedge a piece of wood or similar material between the rotating knife and the left fixed knife. 2. Unscrew the hexagon screw in the interior of the rotor. 3.
