2. Remove the fuel tank cap.
3. Fill the tank to about 1 in. (25 mm) below the top of the
tank, (bottom of the filler neck). Do not overfill. Install
the cap.
4. Wipe up any fuel that may have spilled to prevent a fire
hazard.

Checking the Cooling System

The cooling system is filled with a 50/50 solution of water
and permanent ethylene glycol anti-freeze. Check the
coolant level at the beginning of each day before starting
the engine. The cooling system capacity is approximately
5-1/4 quarts.
1. Clean debris off of the radiator screen, radiator, and oil
cooler (Fig. 23) daily or hourly if conditions are
extremely dusty and dirty; refer to Cleaning the
Radiator and Screen, page 36.

Caution
If the engine has been running, the pressurized,
hot coolant can escape and cause burns.
Do not open the radiator cap when the engine is
running.
Use a rag when opening the radiator cap, and
open the cap slowly to allow steam to escape.
1. Carefully remove the radiator cap (Fig. 24).

2. Check the coolant level in the radiator. The radiator
should be filled to the middle of the horizontal filler
neck.
3. If the coolant level is low, replenish the system. Do not
overfill.
4. Install the radiator cap.
Checking the Hydraulic System
Fluid
The hydraulic system is designed to operate on anti-wear
hydraulic fluid. The hydraulic reservoir is filled at the
factory with approximately 3.3 gallons (12.5 l) of Mobil
424 hydraulic fluid. Check the level of hydraulic fluid
before the engine is first started and daily thereafter.
Group 1 Hydraulic Fluid (Recommended
for ambient temperatures consistently
below 100 F.):
