FORD 2001 F-550 v.1 - Manual (Page 196)

Brake fluid is toxic. If brake fluid contacts the eyes, flush eyes
with running water for 15 minutes. Seek medical if irritation
persists. If taken internally, drink water and induce vomiting. Seek
medical attention immediately.
For vehicles equipped with the 6–speed manual transmission,
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.
For vehicles equipped with the 5–speed manual transmission,
during normal operation, the fluid level in the clutch reservoir will drop
slightly. As this occurs, 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.
