The Workshop Manual provides technical information, component specifications, troubleshooting, and procedures for the removal, disassembly, and reassembly of major components of the 608 Carriers (including the 608 Feller Buncher, 608/T J3000, and the 608 Alternate Head).

Components like the engine, felling head, harvesting head, fire suppression system, and optional equipment are covered in separate manuals from their manufacturers. These additional manuals should be obtained for specifications, parts listings, and servicing procedures to supplement the Workshop Manual.

The Workshop Manual lists likely causes of malfunctions, test procedures to verify them, and steps for adjustment or repair when practical. It also explains the function or operation method of complex components to predict other causes of malfunctions.

Troubleshooting must always be a multi step process. Use the following steps:
1. Know the operation of all machine systems.
2. Ask the operator about symptoms and when they occur.
3. Operate the machine yourself if practical.
4. List all possible causes.
5. Inspect the machine for obvious causes.
6. Eliminate the simple ones by checking oil, changing filters, etc.
7. Carry out diagnostic procedures like pressure, leakage and slippage testing to pin point the cause.
