Menzi Muck A61 16.3 Rotating ball bearing joint The upperstructure and chassis are joined by a roller bearing. Every 100120 operating hours, lubricate the ball bearings by lubricating fittings in 3 to 4 positions with a grease gun. Shorter lubrication intervals: In the tropics, in high relative humidity, in high dust and dirt concentrations, in high temperature fluctuations and continual swing movements. Before and after long intervals, the swing bearing should be well lubricated. Revolve swing bearing during lubrication. Check that a thin coat of grease exists. Internal gearing through a permanent bath The internal gears on the swing bearing and the pinion of the swing gear run through a permanent bath. After 500 operating hours remove the lid and check condition of the gears and of the pinion, and check that a thin coat of grease exists. The teeth of the swing gear and pinion are sufficiently lubricated when all teeth flanks are coated with a thin film of grease.

17. Telescope 17.1 Readjusting at front side The adjustment screws can be readjusted by releasing the locking screws. One turn clockwise reduces the play, and one turn anticlockwise increases the play. It must be ensured that the adjustment screws are not tightened too much and the inner tube is not adjusted too much offcentre, as this can result in excessive wear. The selected adjustment must be checked by retracting and extending the telescope. 17.2 Readjusting at front top and bottom The screws protruding at the top and bottom are used to secure the wearing plates and not to adjust the telescope. For adjustment, adjustment plates with different thicknesses are required. These are pushed under the wearing plates. Attention When adjusting the telescope with shims, it must be ensured that the wearing plate extends 2 mm relative to the securing screw. Readjust the screws if necessary. 17.3 Readjustment at rear The telescope can be readjusted at the top and bottom in the rear. The selected version does not permit a correction of the lateral play. For readjustment the telescope must be extended approx. 100 mm and set down on the ground, the inner tube at the top rear is relieved. Then the rear cover plate must be removed. By unscrewing the nuts, the retaining plate can be removed and the adjustment plates can be pushed in until the correct play is achieved. Assembly is carried out in reverse order. If the lower play is to be adjusted, do not lower the shovel handles to the ground and also remove hydraulic hoses. The inner telescope tube must be secured with suitable measures. The residual pressure on the connections must be released Betriebsanleitung – Seite 0
