Check the hydraulic fluid quality
1. Look through the sight gauge to see the color of the hydraulic fluid. Good hydraulic fluid is
almost transparent.
2. Remove the filler-breather cap on top of the tank.
3. Smell the hydraulic fluid. Good hydraulic fluid has almost no odor.
4. Install the filler cap.
Replace the hydraulic fluid:
• every 3,000 hours.
• if it is dark or milky in color.
• if it has a strong odor.
• if a test laboratory finds the quality is unsatisfactory.
Refer to Replace the hydraulic fluid on page 81.
CAUTION
Heat and other conditions cause hydraulic fluid to degrade. Degraded hydraulic fluid can
cause damage to hydraulic components.
Refer to Hydraulic fluid on page 174 for recommended temperature limits.
Collect a sample of hydraulic fluid from the hydraulic fluid tank and send it to a test
laboratory for analysis.
Contact a hydraulic fluid supplier for a precise report about the hydraulic fluid quality.
