Safety Interlock System
Tests
This machine is equipped with a Safety Interlock System.
Do not attempt to bypass or tamper with the switches and
devices.
DANGER: Mowing in reverse can be
hazardous to bystanders. Tragic accidents can occur if the
operator is not alert to the presence of children. DO NOT
activate the Mow In Reverse (MIR) Option if children are
present. Children are often attracted to the machine and
the mowing activity.
WARNING: If the machine does not pass the five
tests below do not operate the machine. See an authorized
service center
Test 1 — Engine will NOT crank if:
Power Take Off (PTO) lever is ENGAGED, OR
•
Brake pedal is NOT fully pushed down
•
(parking brake OFF)
Test 2 — Engine will crank and start if:
PTO lever is DISENGAGED, AND
•
Brake pedal is fully pushed down (parking brake ON).
•
Test 3 — Engine will SHUT OFF if:
Operator rises off seat with PTO lever ENGAGED, OR
•
Operator rises off seat with brake pedal NOT fully
•
pushed down (parking brake OFF).
Test 4 — Mower Blade Stopping Time Check
The mower blades and mower drive belt will come to a
complete stop in five seconds after the PTO lever is
DISENGAGED. If the mower drive belt does not stop in five
seconds, see an authorized service center.
Test 5 — Mow In Reverse (MIR) Option Check
The engine will SHUT OFF when reverse travel is
•
attempted with the PTO lever ENGAGED and MIR button
NOT depressed while reversing. See Mow In Reverse
(MIR) Option section.

Engine
Check and Add Engine Oil
Use Briggs & Stratton ® Warranty Certified oils for best
performance. Other high-quality detergent oils are
acceptable if classified for service SF, SG, SH, SJ or higher.
Do not use special additives.
Outdoor temperatures determine the proper oil viscosity for
the engine. Use the chart to select the best viscosity for the
outdoor temperature range expected.

result in hard starting.
10W-30 - Above 80 °F (27 °C) the use of 10W-30 can
B cause increased oil consumption. Check oil level more
frequently.

Fuel Recommendation
Fuel must meet these requirements:
• Clean, fresh, unleaded gasoline.
• A minimum of 87 octane. For high altitude use, see section
below.
• Gasoline with up to 10% ethanol (gasohol) is acceptable.
NOTICE: Do not use unapproved gasoline, 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, which will not be covered under
warranty.
To protect the fuel system from gum formation, mix a fuel
stabilizer into the fuel. See Storage section. All fuel is not the
same. If start or performance problems occur, change fuel
providers or brands. This engine is certified to operate on
gasoline.
High Altitude
At altitudes over 5,000 feet (1524 meters), a minimum of 85
octane gasoline is acceptable.
For carbureted engines, high altitude adjustment is required
to maintain performance. Operation without this adjust-
ment will cause decreased performance, increased fuel
consumption, and increased emissions. Contact a Briggs &
Stratton Authorized Service Center 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.
Add Fuel
WARNING: Fuel and its vapors are
extremely flammable and explosive. Always handle fuel
with extreme care. Failure to observe these safety
instructions can cause fire or explosion which could result
in severe burns or death.
