Chapter 1: Travel Motor Inspection

Before starting any maintenance work on the travel motor, ensure the machine is properly secured and the engine is off.

1. Check the belt tension on all drive components
2. Inspect the undercarriage for wear and damage  
3. Verify the transmission fluid level is within specifications
4. Examine the boom cylinder for oil leakage
5. Test the hydraulic pump pressure at 350 bar

Warning: The fuel filter must be replaced every 500 operating hours. Failure to do so may result in engine damage.

Note: Always refer to the parts catalog for correct part numbers when ordering replacement components.

SPECIFICATIONS:
- Hydraulic pump: 250 bar operating pressure
- Travel motor: 180 rpm maximum speed
- Engine oil capacity: 25 liters
- Fuel tank capacity: 400 liters

For technical support, contact your authorized dealer."""
