Operator’s manual Front disc mowersKDF- 33 -After storage period, before the machine is used: check the mower's technical condition, and the transmission in particular, supplement the paint where missing, make sure that all nuts and screws are tightened properly, make sure that all guards are in place, protect all moving parts with grease in order to prevent their baking and creating any sources ofcorrosion, which significantly influences mower's proper operation, check oil level in axis gears and cutterbar. If leaks are found remove them immediately andrefill the oil. If water in oil is found, immediately change the oil as it could cause corrosion ofinternal mechanisms such as gear wheels, bearings, or shafts, and cause breakdowns.Tab. 7. Torque values for boltsIn the absence of specific torque values, the following chart can be used as a guide to themaximum safe torque for a particular size and grade of fastener. There is no torque difference forfine or coarse threads. Torque values are based on clean, dry threads. Reduce value by 10% ifthreads are oiled before assembly.7. LUBRICATION7.1. CutterbarRefilling the oil of the cutterbar is done through the inlet A (Fig. 31). Proper oil level is 0.2" -0.3" from the cutterbar bottom. In order to drain oil from the cutterbar dismount the cutterbarenclosure by releasing bolts (B). The best time to drain the oil is immediately after the operation, ifstill warm. Oil capacities are show in Tab. 8.Fig. 31. Oil check and replacement points on cutterbarAB
