Check the Cooling System

Clean debris from the screen and radiator/oil cooler
daily, more often if conditions are extremely dusty
and dirty.
The cooling system is filled with a 50/50 solution of
water and permanent ethylene glycol anti-freeze.
Check the coolant level in the expansion tank at the
beginning of each day before starting the engine.
Cooling system capacity is 6 quarts (5.6 l).
CAUTION
If the engine has been running, pressurized hot
coolant can escape when the radiator cap is
removed and cause burns.
1. Check the coolant level in the expansion tank. It
should be between the marks on the side of the
tank.

2. If coolant level is low, remove the expansion tank
cap and replenish the system. DO NOT
OVERFILL.
3. Install the expansion tank cap.
Checking the Hydraulic System
Oil
The hydraulic system is designed to operate on any
high-quality detergent oil having the American
Petroleum Institute—API —" service classification"
SF/CC or CD. Oil viscosity—weight—must be
selected according to anticipated ambient temperature.
Temperature/viscosity recommendations are:
Expected Ambient
Temperature
(Extreme) over 32° C
(Normal) 4–37° C
(Cool) –1 to 10° C
(Winter) Below –1° C
Note: Do not mix engine oil and automatic
transmission fluid or hydraulic system component
damage may result. When changing fluids, also
change transmission filter. Do not use Dexron II ATF.
Note: Cold weather start-up may result in "stiff"
steering until the hydraulic system has warmed up.
Using a proper weight hydraulic oil minimizes this
condition.
The transmission and axle housing are shipped from
the factory with approximately 5 quarts (4.7 l) of SAE
10W-30 engine oil. However, check the level of
transmission oil before first starting the engine and
daily thereafter.

1. Position the machine on a level surface, raise the
implement, and stop the engine.
2. Unscrew the dipstick cap (Fig. 6) from the filler
neck and wipe it with a clean cloth. Screw the
dipstick cap finger-tight onto the filler neck, then
