DAILY INSPECTION________________________________________________________

The inspection must be done each day when the engine is stopped.
Do a visual inspection of the mower. Look for indications of wear or loose hardware. Look for any damaged
components.
Check the fuel supply and crankcase oil level. When the engine is cold, all fluids must be at the full level mark.
Test the OPC system.

OPC SYSTEM_____________________________________________________________

The OPC System prevents the engine to start unless the bail handle is closed. The system stops the engine if the
operator releases the bail handle.
Do not operate the equipment with the OPC System disconnected or the system does not operate correctly. Do not
disconnect or prevent the operation of any switch.
Do each of these tests to make sure the OPC System operates correctly. If any of the tests fail, stop the test and have
the system inspected and repaired as shown below:
• The engine does not start during test 1
• The engine does start during test 2
• The engine continues to run during test 3
Refer to the chart below for each test and follow the check (✔) marks across the chart. Turn off the engine between
each test.
TEST 1: The test shows the normal engine start procedure. The bail handle is closed. The engine will start.
TEST 2: The engine must not start if the bail handle is open.
TEST 3: Start the engine with the normal procedure. Release the bail handle. The engine and mower blades must
stop..
