complete with impact mechanism from motor. Pull impact mechanism out of housing. Press bolt

well as pressure spring item 14 and steel ball item 15. Screw out connection piece item 6. Take
off sound absorber disc item 5 und pull out inner parts. Remove valve trigger item 20 with pin
item 18.
Re-assembly
Re-assembly is performed essentially the same as disassembly but in reverse order.
Wear parts - especially the vanes (item 26) should be replaced in due time. They are
considered to be worn when their width is less than 12.5 mm. In case the rotor or the cylinder
bushing would be replaced or the surface re-grinded, the longitudinal play between rotor and
end plates (items 24 and 28) has to be checked. The longitudinal play should be on both
sides approx. 0.05 mm. (Cylinder bushing has to be 0.1 mm longer than the rotor). Secure the
fastening screws with Loctite 243.
After re-assembly the function and performance of the impact wrench have to be checked.
For this, refer to the technical data of the operation and maintenance instruction.
Spare Parts
Only original spare parts may be used. There is no warranty for damages and liability is
disclaimed, if non- original spare parts and accessories are used.
