How to Check/Add Oil
Adding Fuel
1. Remove the dipstick 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 top of the full indicator on the dipstick.
4. If low, add oil slowly into the engine oil fill. Do not
overfill. After adding oil, wait one minute and then
recheck the oil level.
5. Replace and tighten the dipstick.
Fuel Recommendations
Fuel must meet these requirements:
• Clean, fresh, unleaded gasoline
• A minimum of 87 octane/87 AKI (91 RON). High
altitude 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 Storage. All fuel is not
the same. If starting or performance problems occur,
change the fuel providers or change brands. This engine
is certified to operate on gasoline. The emissions control
system for the engine is EM (Engine Modifications).
High Altitude
At altitudes over 5,000 feet (1524 meters), 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 de-
creased performance, increased fuel consumption, and
increased emissions. See a Craftsman Service Dealer for
high altitude adjustment information.
Operation of the engine at altitudes below 2,500 feet (762
meters) with the high altitude kit is not recommended.
WARNING
Fuel and its vapors are extremely flammable
and explosive.
Fire or explosion can cause severe burns or
death.
When Adding Fuel
• Turn engine off and let engine cool at least 3
minutes before removing the fuel cap.
• Fill fuel tank outdoors or in well-ventilated area.
• Do not overfill fuel tank. To allow for expansion of
the fuel, do not fill above the bottom of the fuel tank
neck.
• Keep fuel away from sparks, open flames, pilot
lights, heat, and other ignition sources.
• Check fuel lines, tank, cap, and fittings frequently
for cracks or leaks. Replace if necessary.
• If fuel spills, wait until it evaporates before starting
engine.

Clean the fuel cap area of dirt and debris. Remove
the fuel cap (A, Figure 5). Also see Features and
Controls section.
Fill the fuel tank (B) with fuel. To allow for expansion
of the fuel, do not fill above the bottom of the fuel tank
neck (C).
3. Reinstall the fuel cap.
