Caution!
To prevent damage to the sealing and O-rings, grease
them prior to assembly with grease (Order No. 914392).
Be sure to assemble the parts in the sequence shown on
the spare parts drawing.
-
Press rotor cover <42> with ball bearing <41> on rotor <47> with
fixture <D> (8. Assembly Instructions, fig. 6 + 7)
-
Mount air distributor <40> onto rotor.
-
Assemble seal ring <34> in shut-off piston <33>.
-
Slide shut-off ram <37> into rotor (assembly device) and put both
completely into device <G> (Fig. 9)
-
Install actuating bolt <36> and balls <45>.
-
Fit compression spring <35> in drilling.
-
Fasten pre-assembled shut-off piston <33> to rotor.
-
Lift rotor completely (without shut-off ram <37>) from assembly
device. The shut-off piston is interlocked with the rotor.
-
Assemble centrifugal force controller <32> - <26> (7. Spare Parts
Exploded View)
-
Mount o-ring <38>
-
Insert the pre-assembled parts in the pistol housing. To do so the
bore at the periphery of the air distributor <40> must be adjusted
concentric to the reverse button groove to enable a setting with the
pin.
-
Assemble reverse button <14> and countersunk screw <15>.
-
Insert rotor cylinder <44> with shear keys <43> into pistol grip
housing.
-
Insert the blades <46> into the rotor grooves.
-
Put the rotor cover and the ball bearing into the pistol grip housing.
-
Assemble sleeve <50>.
-
Slide shut-off ram <37> back into the rotor
Do only switch on motor when pulse unit <90>/135> and
housing <94>/<139> are assembled.
Caution!
When installing the screen <8>/<11>, be sure the circlip
<9>/<12> is lying flat on the screen.

Allowed only if filling with oil filling unit <A> can be
guaranteed. The pulse unit must have cooled down to
room temperature.
Caution!
Be sure retaining rings are not extended excessively
-
Quick-change model: remove retaining ring, ring, compression
spring, sleeve and ball first.
-
Remove retaining ring <89>/<134> and pull housing <94>/<139>
off pulse unit.
-
Fix fixture <C1> in vice and insert pulse unit in fixture at motor input
slot (8. Assembly Instructions, fig. 1).
To avoid endangering health or environment, always
comply with the local regulations for security and prevention
of accidents.
Avoid direct skin contact when working with oil to prevent
skin irritations.
-
Remove set bolt <80>/<125> and ball <79>/<124>.
-
Loosen the bearing ring <78>/<123> with the device <C2>.
-
Remove the bearing ring above an oil pan and pull the hydraulic
rotor <73>/<118> from the housing.
Hydraulic roller is spring-loaded!
-
By removing the needle roller <88>/<133> all parts built in the
hydraulic rotor can be removed.
-
Clean all parts.
Caution!
Always only use original spares from CLECO. Use of
foreign spares entitles the manufacturer of the tool to void
the warranty.
