5.10 Mounting instruction
5.10.1 Exciter
When disassembling exciter components, always remove eccentric
weights first. When assembling, the eccentric weights have to be
installed last of all. When installing exciter shafts mind marking of
toothed gears. Assembly of exciter shaft is correct when all eccentric
weights point down while piston is at half stroke. During assembly of
eccentric weights on exciter shaft, keep shafts blocked to avoid
pinching of fingers. Mind lefthand thread when assembling V-belt
pulley. Tighten all screws with the prescribed torque, mind qualities of
screws (see screw head).

1. Remove apron (17) by undoing the screws (16).
2. Move centre pole into vertical position, move control handle (6) right
into the reverse position, open filler bore (15).
