TO work with the rear PTO shaft, remove the protective cap 1 (Figure 3.2.1), which co-
vers the shank 9. For this purpose it is necessary to squeeze the cap near its base and pull it
downwards and towards yourself. When work with the RPTO is finished, it is mandatory to in-
stall the protective cap 1 back in its place, for which purpose it is necessary to put the cap 1
onto shank 9 and push on it lengthwise until the cap 1 reliably fixes in the housing 6 hole.
1 – protective cap; 2 – bolt; 3 – nut; 4 – rear PTO shaft cover; 5 – housing; 6 –
cover; 7 – bolt; 8 – plate; 9 – shank.
