General Operating Safety
Be sure to read all information in the Operator Safety
section before attempting to operate this unit. Become
familiar with all of the controls and how to stop the unit.

ate it. See an authorized dealer.
Safety Interlock System Tests
This unit is equipped with a Safety Interlock System.
Do not attempt to bypass or tamper with the switches/
devices.
Test 1 -- Engine should NOT crank if:
• PTO switch is ON, OR
• Brake pedal is NOT fully depressed (parking brake
OFF), OR
• The cruise control lever is NOT in NEUTRAL.
Test 2 -- Engine SHOULD crank and start if:
• Operator is sitting in seat, AND.
• PTO switch is OFF, AND
• Brake pedal is fully depressed (parking brake ON),
AND
• The cruise control is in NEUTRAL.
Test 3 -- Engine should SHUT OFF if:
• Operator rises off seat with PTO engaged, OR
• Operator rises off seat with brake pedal NOT fully
depressed (parking brake OFF).
Test 4 -- Check Mower Blade Stopping Time
Mower blades and mower drive belt should come to a
complete stop within five seconds after electric PTO
switch is turned OFF. If mower drive belt does not stop
within five seconds, see an authorized dealer.
Test 5 -- Reverse Mow Option (RMO) Check
• Engine should shut off if reverse travel is attempted
if the PTO has been switched on and RMO has not
been activated.
• RMO light should illuminate when RMO has been
activated.
WARNING
Mowing in reverse can be hazardous to bystand-
ers. 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.
Check Tire Pressure
Tires should be checked periodically to provide the
optimum traction and to guarantee the best cut (see
Figure 4).
NOTE: These pressures may differ slightly from the
"Maximum Inflation" stamped on the side walls of the
tires.

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.
