1.3 Hydraulic System - Special Instructions
1.3.1 Hydraulic System Safety
To minimize risk of serious injury or death, follow these
hydraulic servicing precautions:
•
Follow all necessary lockout/tagout procedures.
•
Hydraulic systems have residual, stored pressure. Relieve all pressure
from the hydraulic system before servicing.
•
Allow fluid to cool before working on system.
•
Hydraulic fluid escaping under pressure can have sufficient force to enter
eyes and penetrate skin. If fluid gets in eyes or skin, flush with large
quantities of water and seek medical attention.
•
Wear eye protection when servicing hydraulic components or systems.
•
Keep all hoses and connections in good serviceable condition. Check
before start-up and periodically during operation.
