Oil Pressure

If the oil pressure is too low, a pressure switch (if equipped)
will either stop the engine or activate a warning device on
the equipment. If this occurs, stop the engine and check
the oil level with the dipstick.

If the oil level is below the ADD mark, add oil until it reaches
the FULL mark. Start the engine and check for proper pres-
sure before continuing to operate.

If the oil level is between the ADD and FULL marks,

do not

start

the engine. Contact an authorized dealer to have the

oil pressure problem corrected.

1. Pull up tractor hood to access the fuel tank.

2. Clean the fuel cap area of dirt and debris. Remove

the fuel cap (

, Figure 6).

3. Fill the fuel tank (

) with fuel. To allow for expansion

of the fuel, do not ll above the bottom of the fuel tank

neck.

4. Reinstall the fuel cap.

Checking/Adding Oil

Before adding or checking the oil

• Place engine level.

• Clean the oil ll area of any debris.

1. Remove the dipstick (

, Figure 5) and wipe with a

clean

cloth.

2. Insert and tighten the dipstick.

3. Remove the dipstick and check the oil level. It should

be at the FULL mark (

) on the dipstick.

4. If low, add oil slowly into the engine oil ll (

Do not

over ll.

After adding oil, wait one minute and then

recheck the oil level.

NOTE:

Do not add oil at the quick oil drain (if equipped).

5. Replace and tighten the dipstick.

High Altitude

At altitudes over 1,524 meters (5,000 feet), a minimum 85
octane/85 AKI (89 RON) gasoline is acceptable. To remain
emissions compliant, high altitude adjustment is required.
Operation without this adjustment will cause decreased
performance, increased fuel consumption, and increased
emissions. See an authorized dealer for high altitude ad-
justment information.

Operation of the engine at altitudes below 762 meters
(2,500 feet) with the high altitude kit is not recommended.

Fuel Recommendations

Fuel must meet these requirements:

• Clean, fresh, unleaded gasoline.

• A minimum of 87 octane/87 AKI (91 RON). High alti-

tude use, see below.

• Gasoline with up to 10% ethanol (gasohol) or up to

15% MTBE (methyl tertiary butyl ether) is acceptable.

CAUTION:

Do not use unapproved gasolines, such as

E85. Do not mix oil in gasoline or modify the engine to run
on alternate fuels. This will damage the engine compo-
nents and

void the engine warranty.

To protect the fuel system from gum formation, mix a fuel
stabilizer into the fuel. See the

Storage

section. All fuel is

not the same. If starting or performance problems occur,
change fuel providers or change brands. This engine is
certi ed to operate on gasoline. The emissions control sys-
tem for this engine is EM (Engine Modi cations).

WARNING

Fuel and its vapors are extremely ammable and
explosive.

Fire or explosion can cause severe burns or
death.

When Adding Fuel

• Turn engine o and let engine cool at least 3 minutes

before removing the fuel cap.

• Fill fuel tank outdoors or in well-ventilated area.
• Do not over ll fuel tank. To allow for expansion of the

fuel, do not ll above the bottom of the fuel tank neck.

• Keep fuel away from sparks, open ames, pilot lights,

heat, and other ignition sources.

• Check fuel lines, tank, cap, and ttings frequently for

cracks or leaks. Replace if necessary.
