• The brake pedal is NOT fully depressed (parking brake
OFF).
Test 2 — Engine SHOULD crank and start if
• The PTO switch is OFF, AND
• The Brake pedal is fully depressed (parking brake ON).
Test 3 — Engine should SHUT OFF if
• The operator rises off the seat with the PTO engaged, OR
• The operator rises off the seat with the brake pedal NOT
fully depressed (parking brake OFF).
Test 4 — Mower Blade Stopping Time Check
• The mower blades and mower drive belt should come to
a complete stop within five seconds after the PTO switch
is turned OFF.
• If the drive belt does not stop within five seconds, see an
authorized dealer.
Test 5 — Reverse Mowing Option (RMO) Check
• The engine should shut off if reverse travel is attempted
if the PTO has been switched ON and the RMO has not
been activated.
• The RMO light should come on when the RMO has been
activated.
DANGER
Mowing in reverse can be hazardous to bystanders. Tragic
accidents can occur if the operator is not alert to the
presence of children. Never activate the Reverse Mowing
Option (RMO) if children are present. Children are often
attracted to the machine and the mowing activity.

Check and Add Engine Oil
®
Use of Briggs & Stratton
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.
A SAE 30 - Below 40 °F (4 °C) the use of SAE 30 will result in hard
starting.
B 10W-30 - Above 80 °F (27 °C) the use of 10W-30 may cause
increased oil consumption. Check oil level more frequently.

*Below 40°F (4°C) the use of SAE 30 will result in hard starting
**Above 80°F (27°C) the use of 10W-30 may cause increased oil consumption.
Check oil level more frequently.
1. Put the unit on a level surface as shown in Figure 4.
2. Stop the engine.
3. Make sure that the oil fill area is clean.
4. Remove the dipstick (A, Figure 5). Remove the
remaining oil from the dipstick.
5. Install and tighten the dipstick.
6. Remove the dipstick again, and check the oil level. Make
sure that the oil level is at the top of the FULL mark (B)
on the dipstick.
7. If the oil level is FULL, install and tighten the dipstick.
8. If the oil level is LOW, add oil into the engine oil fill tube
(C). Do not overfill.
Note: Do not add oil at the quick oil drain (if equipped).
9. Wait one minute, and check the oil level again.
10. 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 the correct oil
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.
Add Fuel
Fuel must meet these requirements:
• Clean, fresh, unleaded gasoline.
• A minimum of 87 octane / 87 AKI (91 RON). For 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 cause
damage to 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. 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).
