• Check all of the fasteners after the work is complete.
Tighten any loose bolts, nuts, or screws.
• Check all electrical and fuel connections to make sure
that they are secure and the machine is in a safe working
condition.

9.2 Fluids and Lubricants

The machine requires various fluids and lubricants for operation
and maintenance.
9.2.1 Lubricant Handling and Storage
For optimum machine efficiency, use clean lubricants and clean
containers to handle all lubricants. Store lubricants in an area
that is protected from dust, moisture, and other contaminants.
9.2.2 Engine Oil
For engine maintenance and service information, see the
engine manufacturer's manual.
Briggs & Stratton® Warranty Certified oils are recommended
for the best engine performance. However, other high-quality
detergent oils are permitted if they are classified for service SF,
SG, SH, SJ, or higher. Do not use special additives.
Outdoor temperatures determine the required engine oil
viscosity. Select the best oil viscosity for the expected outdoor
temperature range. Use the following chart as a guide:

A SAE 30 – Below 40 °F (4 °C) the use of SAE 30 results
in hard starting.
B 10W-30 – Above 80 °F (27 °C) the use of 10W-30
may cause increased oil consumption. Check the oil
level frequently.

9.2.3 Engine Fuel
For complete fuel information and use at high altitudes, see
the engine manufacturer's manual.
Fuel must meet the following specifications:
• Clean, fresh, unleaded gasoline.
• Minimum of 87 octane / 87 AKI (91 RON).
• Gasoline with up to 10% ethanol (gasohol) is acceptable if
the fuel is fresh (less than three months old).
If the machine will be in storage for longer than three months,
replace the fuel with one of the following fuel types:
• An alkylate fuel
• An engineered fuel that is high octane, ethanol-free, and
formulated with power detergent to prevent the buildup of
insoluble solids (deposits).
For instructions, see Replace the Engine Fuel on page 54.
9.2.4 Grease
Use an SAE multi-purpose high temperature grease with extreme
pressure (EP) performance. An SAE multipurpose lithium-based
grease is an acceptable substitute.
9.2.5 Hydraulic Fluid
Use Dexron® III automatic transmission fluid (ATF) for all
operating conditions.
The following ATFs are acceptable substitutes:
• Dexron VI
• Mercon®
