2 Safety Instructions and Proper Use 2.1 Requirements on the Operator This operating manual is intended for persons who are assigned the operation and supervision of Fritsch Jaw Crusher. Persons under the influence of health impairments, medications, drugs, alcohol or excessive fatigue may not operate the instrument. The instrument may only be operated by authorised persons and may only be maintained and repaired by trained experts.
2.3 Obligations of the Operator This manual must be carefully read and understood before using the product. Use of the product requires specialised knowledge and may only be undertaken by commercial users. The operating personnel must be familiar with the contents of the operating manual. It is therefore very important that this operating manual also actually be provided to these persons. It must be ensured that this operating manual always remains alongside the instrument.
2.5 Machine safety instructions We recommend that a safety logbook should be kept in which all work (service, repairs etc.) carried out on the machine should be entered. Use only original accessories and original spare parts. The safety of the machine is impaired if this instruction is not followed. Operating personnel must always operate the machine with safety in mind. Do not run the laboratory jaw crusher unsupervised.
2.6 Safety equipment TIP Safety equipment must be used in accordance with the regulations and must not be rendered inoperative or be removed. All safety equipment must be checked regularly for completeness and function. Inside the jaw crusher „pulverisette 1“ several elements independently acting contribute to security: 1. Reaching into the funnel (1) is prevented by the zigzag-shaped material passageway. 2.

4 Installation 4.1 Transportation CAUTION The weight of the laboratory jaw crusher is Model I: 177 kg Model II: 205 kg The laboratory jaw crusher is delivered on a transport pallet with a wooden cover. We recommend using a forklift or pallet truck to transport the packaged instrument. 4.2 Unpacking • Pull the staples out of the cover with a pulling tool (or pliers). • Lift it off the transport pallet with the help of a second person. • Compare the contents of the delivery with your order. 4.
2. Pull its free end through the two holes at the narrow side of the jaw crusher holes and fasten it at the rope in the same way you did first. 3. Do the same with a second rod and rope at the opposite side. 4. With the help of the iron rods 4 support people carry the jaw crusher; the fifth one prevent it from swinging during transport. • The jaw crusher must be placed on an even, stable surface. If you wish, you can also screw it to such a surface or to a ground plate. 4.
2. Lift off the rubber seal on the funnel opening of the jaw crusher. To do so, remove the 4 cylinder head screws with washers using the Allen key. 3. Pull the rubber seal over the funnel neck. Take note of the positions of the holes in the filling funnel and rubber seal. 4. Insert the filling funnel into the funnel opening on the top of the laboratory jaw crusher. 5. Screw the filling funnel onto the housing with the 4 previously removed cylinder head screws and washers. 6.
4.6 Electrical connection CAUTON Secure the electrical system! Danger of damage due to short-circuit. Make certain that the socket is connected to a mains line secured with a residual current circuit breaker. Kindly compare the tension and current values indicated on the sign with the values of the existing power supply system before connecting the instrument. (See chapter 3) 4.6.1 Matching the jaw crusher to the mains voltage DANGER 4.6.
4.7 Initial switch-on / performance check CAUTION Danger of crushing! Only start the jaw crusher with the funnel (1) attached! The machine may be switched on only after all work described in the chapter 4 on Installation has been carried out. During the first operating hours, it is possible that some grease may escape from the eccentric cam bearing of the movable crushing jaw (see also chapter 8.3).

5.2.1 Mounting the crushing plates TIP The crushing plates have different shapes. The fixed crushing plate (18) has plane parallel surfaces, the movable crushing plate (22) is convex on the crushing surface and it is a bit longer. CAUTION Crushing jaw (15) hold on tight! Part weighs about 6.5 kg To replace the fixed crushing plate (18), remove the guide bolt (3) and take out the crusher jaw (15).
5.2.2 Checking the gap (25) fly-wheel gap 0.5-1mm After installing the crushing plates (18, 22), you must check the gap between the plates: To do this, you must remove the belt guard outside (9). The fastening screws of the belt guard outside (9) are located under the edge protection (8). When the belt guard outside (9) is removed, the fly-wheel (25) can be turned by hand. Set the indexing cranked handle (7) to the lowest setting.
5.2.3 Mounting the support walls WARNING The fly-wheel (25) is very heavy. At least 2 people are required for disassembly. Replacing the lateral support walls (13) is practically only required if the material of the crushing plates (18. 22) is replaced by another one (i.e. from tool steel to stainless steel) and if even the smallest (P.P.M. range) contamination (abrasion) from the support walls has to be avoided. First lift out the fixed crusher jaw (17) as described in chapter 5.2.1.
5.3 Crushing of material 5.3.1 Setting the jaw gap The opening of the gap between the crusher plates determines the average grain size of the crushed material. With the indexing cranked handles (7) the opening gap can be selected by steps between about 1 mm and 15 mm. (In the lowest position the gap is the smallest). To select a different gap, pull out the knurled knob of the indexing cranked handles (7) and insert the indexing cranked handles into the desired position.
5.3.4 Final size The obtainable final size depends upon the selected gap setting (about 1 mm to 15 mm). The gap setting determines only one dimension of the crushed material. This means, that for instance flaky shaped material can have a completely different size in another dimension compared with the set gap. If this should be the case, in many cases a second pass of he crushed material through the crusher will considerably reduce the amount of the grains being larger in one dimension.
