Observe the following precautions when disassembling and assembling drive shaft.
●Perform work in a location which is as dust-free as possible.
●Before disassembling and assembling, clean the outside of parts.
●Prevention of entry of foreign objects must be taken into account during disassembly of the service location.
●Disassembled parts must be carefully reassembled in the correct order. If work is interrupted, a clean cover must be placed over parts.
●Paper shop cloths must be used. Fabric shop cloths must not be used because of danger of lint adhering to parts.
