FORD 2004 F-550 v.3 - Manual (Page 261)

CLUTCH FLUID (IF EQUIPPED)
Check the clutch fluid level. Refer to the Scheduled Maintenance
Guide for the service interval schedules.
Use only a DOT 3 brake fluid designed to meet Ford specification
ESA-M6C25–A. Refer to Lubricant Specifications in this chapter.
Brake fluid is toxic. If brake fluid contacts the eyes, flush eyes
with running water for 15 minutes. Seek medical attention if
irritation persists. If taken internally, drink water and induce vomiting.
Seek medical attention immediately.
During normal operation, the fluid level in the clutch reservoir should
remain constant or rise slightly. If the fluid level drops, refill the fluid
level to the step in the reservoir.
1. Clean the reservoir cap before
removal to prevent dirt and water
from entering the reservoir.
2. Remove cap and rubber
diaphragm from reservoir.
3. Add fluid until the level reaches
the step in the reservoir.
4. Reinstall rubber diaphragm and
cap onto reservoir.
