Information on motor running
If the motor does not at all turn after re-assembly, light tapping with a rubber hammer on motor housing is
helpful.
The rotor places and comes into a free-wheel position between the end plates. If not, check lengths of the
rotor, cylinder bushing and vanes.
a. The vanes shall neither jut out laterally of the rotor slots, nor project on the rotor.
b. Cylinder bushing has to be 0.08 mm to 0.10 mm longer than the rotor.
After finishing of re-assembly make functional gauging of the pneumatic drill. For this refer to the technical
specification of the operation and maintenance manual.
