Disassembly of the tool and/or installations of accessories must only be performed by qualified maintenance personnel.

Required tools:

2. Loosen the front cap nut using an adjustable spanner. Remove the tool from the vise.

3. Pull out the angle gear carefully from the tool.

4. Remove the following parts from the angle gear housing:

   1. the lock ring (keep for later use)

   2. the sealing washer (to be discarded)

   3. the front cap nut (to be discarded)

5. Mount the following parts on the angle gear housing:

   1. new applicable front cap nut. Apply a thin layer of grease on the inside of the cap nut.

   2. new sealing washer

6. Replace the O-ring on the motor housing with a thicker O-ring of the same diameter. Apply a thin layer of grease on the O-ring and on the lower section of the motor housing.
