the radial auxiliary bore of the air distributor <27> must be aligned
with the centre of the switch-over groove.
- Press the roller bearing <28> together with the rotor cover <29>
onto the rotor <33> using <D> (8. Assembly Instructions,
figs. 8 + 9). Then install it in the pistol grip housing.
- Assemble reverse button <14> and suspension bail <15>.
- Insert rotor cylinder <31> with shear keys <30> into pistol grip
housing.
- Insert the blades <32> into the rotor grooves.
- Insert ball bearing <35> and shim ring <36> (right position) with
circlip <37> into rotor cover <34> and mount all with sleeve <38>
into the pistol grip housing.

- Reassemble by reversing the disassemby process as shown
(7. Spare parts exploded view).
- Push parts <46> - <41> (
the hydraulic cylinder <47>/<78> and secure them with the circlip
<40>/<71>
- Assemble o-ring <59>/<87> on hydraulic rotor <54>/<85>.
- Push fixture <E>
(8. Assembly instructions, fig. 2).
- Insert compression springs and blades over the slots of fixture
<E> by pressing them down and turning the hydraulic rotor into the
hydraulic rotor slots (fig. 3).
- Adjust control blade <53>/<84> (with long shaft end) towards bore
in fixture (fig. 4).
- Assemble needle roller <48>/<79> into hydraulic cylinder <47>/
<78>.
- Insert the preassembled parts by means of fixture <E> into
hydraulic cylinder <47>/<78> so that needle roll <48>/<79> and
bore met. Remove <E> (fig. 5).
- Mount disc <58>/<86> and positon over needle roll <48>/<79>.
Caution!
The control slides at the outside diameter of the disk
points toward the slots in the rotor.
- Put up bearing ring <61>/<89> with o-ring <60>/<88>.
- Insert the pulse unit into device <C1>.
