Adding Fuel; Oil Pressure; Fuel Recommendations - Snapper SPX-100 Operator's Manual

Check or Add Oil
Before adding or checking the oil
• Place the tractor on a level surface (see Figure 4).
• Clean the oil fill area of any debris.
1. Remove the dipstick (A, 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 (B) on the dipstick.
4. If low, add oil slowly into the engine oil fill (C). Do not
overfill. 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.

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
pressure 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.

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) is acceptable.
NOTICE: Do not use unapproved gasolines, such as E15
and E85. Do not mix oil in gasoline or modify the engine to
run on alternate fuels. Use of unapproved fuels will damage
the engine components 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
fuel providers or change brands. This engine is certified to
operate on gasoline. The emissions control system for this
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 decreased
performance, increased fuel consumption, and increased
emissions. See an authorized Briggs & Stratton Dealer for
high altitude adjustment information.
Operation of the engine at altitudes below 2,500 feet
(762 meters) with the high altitude adjustment is not
recommended.

Adding Fuel

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.
1. Clean the fuel cap area of dirt and debris. Remove the
fuel cap (A, Figure 6). Also see Features and Controls
section.
2. 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.
