The Service Manual is intended to provide technical information, component specifications, troubleshooting and removal, disassembly and reassembly procedures for most of the major components of the machine.
Certain components such as the engine, felling head, and fire suppression system are covered in individual manuals provided by the respective manufacturers. For specifications, parts listings and servicing procedures these manuals should be obtained to supplement the Service Manual.
When practical the Service Manual lists likely causes of malfunctions, offers test procedures to verify causes and then illustrates the steps for the adjustment or repair procedure(s).
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 pinpoint the cause
