Temporary decommissioning When the attachment is not used for prolonged periods, disconnect its hydraulic system. 6.5. -
Page 31: Regular Maintenance
• Determine maintenance intervals based on the specific requirements in relation to the production cycle of the attachment; • Every day, before using the attachment, the operator should visually inspect the general state of its components and request maintenance if they notice any strange noises or fault conditions; •... - Page 32 WARNING! Wear P.P.E. whenever carrying out scheduled maintenance. Scheduled maintenance table The machine must be isolated for maintenance. Operation Interval Every 8 hours Grease the hinges, including the slew ring, and replace any damaged grease lubricators (see Lubrication). Every 8 hours Check that none of the screws are loose or damaged.
-
Page 33: Lubrication
7.4.1 Lubrication The attachment must be lubricated at all the greasing points (G) indicated on the respective plate. Lubrication intervals must be determined based on operating conditions. The attachment must be re- lubricated before or after prolonged periods of inactivity. This is especially true for the winter break. Take care that no detergent penetrates the ball roller system or damages the gaskets. -
Page 34: Table Of Lubricants
7.4.2. Table of lubricants We have checked the compatibility of the greases shown in the table with the materials used for spacers and gaskets and consider them suitable for use in the bearings. For this reason, if the user wishes to use lubricants differing from those shown here they must obtain confirmation from the supplier or maker that the selected lubricant is suitable for use and that its specifications are at least equivalent to those of the products listed in the table. -
Page 35: Tightening The Screws
7.4.3. Tightening the screws Tightening must be performed exclusively by specialised technicians using a torque wrench and applying the torque values indicated in the table Tightening Torques and Stresses. The screws may only be re- tightened once, after which they must be replaced. Tightening Torques and Stresses 8.8-(8G) 10.9-(10K) -
Page 36: Extraordinary Maintenance

- Page 38 Adjustment • Partially close the jaw of the attachment so that the tip blade (Z) on the jaw (Q) meets the guide blade (E). • Slowly move the jaw (Q) and check the clearance between the tip blade (Z) and the guide blade (E) in several positions.
- Page 39 IMPORTANT! Turning the blades of the attachment increases the quality of the cut and extends the life of the blades. Tip blade The tip blade (Z) is located on the front of the jaw (Q) and is used to penetrate the material to start the cut. DANGER! When adjusting the blades, it is necessary to move the jaw.
- Page 40 Front blade The front blade (D) is located at the front of the chassis (A) and is used to improve the penetration of the jaw (Q). Adjustment • Slowly move the jaw (Q) and check the clearance between the tip blade (Z) and the front blade (D). Make sure that it never exceeds 0.4mm (it is initially adjusted to 0.15mm).
- Page 41 Replacement • If there is still excessive clearance despite using all the shims provided (H) and after having rotated it, then the front blade (D) must be replaced. • Remove the worn front blade and all the shims by loosening the screws. •...
