6 Technical Information 6.1 Adjustment of thickness plate Figure 6-1 Adjustment of thickness plate 1. Loosen the two screws (4) and move the thickness plate to within 1-1.5 mm of the knife (2), as shown in Figure 6-1. 2. Fasten the thickness plate in position by firmly tightening the two screws (4). Service Instructions RP-M251CE/RP-M301CE/RP-M351CE 6-3
6 Technical Information Figure 6-2 Adjustment of thickness plate As a result of shocks during transport, the thickness plate may sometimes come into contact with the knife; to re-set the thickness plate proceed as follows: 1. Lift the machine and loosen the screw (4) on the bracket (3). 2. Slowly rotate the thickness plate until the center of curvature of the edge next to the blade coincides with the centre of the knife, with an even opening of 1-1.5 mm between the knife and the thickness plate, as shown above. 3. Fasten the thickness plate by tightening the screw (4) firmly. 6-4 Service Instructions RP-M251CE/RP-M301CE/RP-M351CE
6 Technical Information 6.2 Sharpener settings/adjustments RP-M251CE/RP-M301CE The knife must be replaced when its diameter falls to 10 mm less than its nominal value. The reduction of the knife diameter could mean that a corrective adjustment of the sharpener is needed. It should be positioned as follows: 1. Lift up the protection cover (pos 1 fig 6.3) and rotate the sharpener into its sharpening position (fig 6.3). 2. Loosen the two screws (pos 1 fig 6.3); loosen the bolt (spanner 22) (pos 3) and remove the sharpener assembly (pos 4). 3. Rotate the bolt (pos 5 fig 6.4) clockwise as far as is necessary, and assemble the sharpener assembly by checking that both stones are positioned as in fig 6.5, with the finishing stone parallel to the knife (fig 6.3); check that there is no interference with the movable protection (pos 6 fig 6.3). Put the sharpener into its non-operational position and check that there is no interference between the finishing stone and the knife. Fix the sharpener assembly by fastening the bolt (pos 3 fig 6.3). 4. Reset the knob (pos 2 fig 6.3) and fasten the two screws (pos 1 fig 6.3).

The reduction of the knife diameter could mean that a corrective adjustment of the sharpener is needed. It should be positioned as follows: 1. Lift up the protection cover (pos 1 fig 6.6) and rotate the sharpener into its sharpening position (pos 2). 2. Remove the caps (pos 2 and 3 fig 6.6); loosen the grain (pos 4 fig 6.7) and lower the sharpener until both stones are positioned in relation to the knife as shown in figs 2 and 2, and then fasten the grain (pos 4). 3. Loosen the grain (pos 5 fig 6.7); put the sharpener into its non-operational position (fig 6.6), and rotate the cam (pos 6 fig 6.7) anti-clockwise as far as possible. Loosen the grain (pos 8) and rotate the eccentric cam clockwise or anticlockwise (pos 9 fig 2) and check that the movable protection (pos 7 fig 6.6) projects beyond the knife edge, as shown in fig 6.6a, and then fasten the grain (pos 8 fig 6.7). 4. Return the sharpener to its sharpening position (fig 6.7) and rotate the cam clockwise (pos 6 fig 6.7), checking that there is no interference between the trimming stone and the movable protection (pos 7 fig 6.7) during the rotation, and then fasten the grain (pos 5).

7 Appendices 7.2 Routine maintenance 7.2.1 Cleaning The slicer should be cleaned often; at least once a day. To clean all accessible parts, use a cloth moistened with water and detergent (a non aggressive one): do not use water jets! For effective cleaning follow the instructions given in the Instruction Manual. 7.2.2 Knife control Check the knife diameter and replace the knife when its diameter is 10mm less than its nominal diameter; for the replacement of the knife look at the specific technical sheet. 7.2.3 Knife sharpening When the slicing is not satisfactory, it is necessary to sharpen the knife. Before sharpening the knife clean the sharpening stone. If the sharpening is not satisfactory replace both stones. 7.2.4 Lubrication This operation should be made after the cleaning of the slicer, or each time when the carriage does not slide smoothly; use Berkel slicer oil. 7.2.5 Sliding of the food holding carriage If the carriage does not slide smoothly, lubricate its sliding bar as indicated in the Instruction Manual. 7.2.6 Endgrip sliding If the endgrip does not slide smoothly, lubricate its sliding bar as indicated in the Instruction Manual. 7.2.7 Supply cord Check periodically for wear of the supply cord: if you see that there are evident cuts, replace immediately. 7-4 Service Instructions RP-M251CE/RP-M301CE/RP-M351CE
