Installation of the coupling
Push together the machines to be coupled and align them according to the dimensioned drawing.
Oil the teeth of the coupling part (1), the flanged sleeve (5) and the adapter (4).
Push the flanged sleeve (5) over the teeth of the adapter (4) and position and hold the assembly (4; 5)
between the coupling parts (1; 3).
Noting the marking, feed the adapter (4) into the teeth of the coupling part (1).
Noting the marking, push the flanged sleeve (5) onto the teeth of the adapter (4) again and hold it.
Bring the marking of the flanged sleeve (5) and that of coupling part 3 into line. Insert the closefitting bolts
(8) and tighten the hexagonal nuts (9) (for tightening torques, see table 2).
Insert the circlips (6) into the coupling parts (1; 3) without leaving a gap.

Assignment of the tightening torques and wrench widths
The use of an impact screwdriver is not permissible!
Tightening torques apply to bolts with untreated surfaces which are not or only lightly oiled (coefficient of
friction μ = 0.14). The use of lubricant paint or lubricant, which affects the coefficient of friction "μ", is not
permitted.
The specified tightening torques T
Class "C", with an outputtorque scatter of ± 5 %.
