Removing Air From The Fuel System
After replacing the filter element or when the fuel tank
has run out of fuel, the air must be removed from the fuel
system before starting the engine.

Diesel fuel or hydraulic fluid under pressure can
penetrate skin or eyes, causing serious injury or
death. Fluid leaks under pressure may not be visible.
Use a piece of cardboard or wood to find leaks. Do

enters skin or eyes, get immediate medical attention
from a doctor familiar with this injury.
