Oil Recommendations
We recommend the use of 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.
** Above 80° F (27° C) the use of 10W30
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.

Oil Recommendations
Safety Interlock System Tests
This unit is equipped with a Safety Interlock System. Do not
attempt to bypass or tamper with the switches and devices.
WARNING
If the unit does not pass a safety test, do not operate
it. See an authorized dealer.
WARNING
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 RMO if children
are present. Children are often attracted to the unit and the
mowing activity.
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.
