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.
WARNING
If the unit does not pass a safety test, do not operate 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
• Operator is NOT in seat.
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).
Test 3 — Engine should SHUT OFF if:
• Operator rises off seat.
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 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.
Check Tire Pressure
Tires should be checked periodically to provide the
optimum traction and to guarantee the best cut (see Figure
7).
NOTE:
These pressures may differ slightly from the “Maxi
-
mum 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.
* 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.
