2. If the hydraulic oil level is low, remove the hydraulic oil
tank cap just above the oil level sight glass (Figure 14)
and add the correct amount of hydraulic oil to bring the
hydraulic oil level to a normal, safe operating level. Use
Shell Oil Tellus 46.
Figure 14. Adding Hydraulic Oil (Filler Hole)
3. Check the oil level in the
lubrication box
If low, fill with up to 4.4 gallons of SAE #30 motor oil
(Figure 14). The oil level must be checked daily. The

INSPECTION
CLEANING THE RADIATOR
The engine may overheat if the radiator fins become
overloaded with dust or debris. Periodically clean the
radiator fins with compressed air. Cleaning inside the
machine is dangerous, so clean only with the engine turned
off and the
negative
battery terminal disconnected.
AIR CLEANER
Periodic cleaning/replacement is necessary. Inspect air
cleaner as referenced in the maintenance section of this
manual.
FAN BELT TENSION
A slack fan belt may contribute to overheating or to
insufficient charging of the battery. Inspect the fan belt for
damage or wear and adjust it in accordance with the
Zenith
Engine Owner’s Manual.
The fan belt tension (Figure 16) is proper if the fan belt
bends 0.4–0.6 inches (10–15 mm) when depressed with
the thumb as shown below.
