3. If the oil level is too low, refer to 6.1 Lubricants, Fluids, and
System Capacities, page 237 for oil specifications and add
oil as follows:
IMPORTANT:
Clean the area around the filler plug to prevent debris from
entering the tank.
a. Turn plug handle (B) counterclockwise until it is loose
and remove the plug by pulling it straight out.
b. Open breather cap (A).
NOTE:
This will allow the hydraulic system to vent, speeding
up the filling process.
c. Add hydraulic oil until the level in the tank is at the full
indicator mark.
d. Reinstall breather cap (A) and filler plug (B) and turn
the filler plug handle clockwise until it is secure.
NOTE:
After running up a header, check the oil level again.
4.1.4 Checking Fuel Separator
The fuel separator removes water and sediment from the fuel to prevent damage to the engine. It will need to be
inspected to ensure that it is clean.
Figure 4.8: Fuel Filter
1. Place a container under filter drain valve (A).
2. Turn drain valve (A) by hand 1 1/2 to 2 turns

3. Drain the filter sump of water and sediment until clear fuel
is visible. Clean the sump as needed.
4. Turn drain valve (A) by hand 1 1/2 to 2 turns clockwise
until tight.
