4.1 DAILY INSPECTION________________________________________________________
1. Perform a visual inspection of the entire unit, look for
signs of wear, loose hardware, and missing or damaged
components. Check for fuel or oil leaks to ensure con-
nections are tight and hoses and tubes are in good con-
dition.
2. Check the fuel supply, radiator coolant level, crankcase
oil and air cleaner indicator. All fluids must be at the full
level mark with engine cold.
3. Make sure all mowers are adjusted to the same cutting
height.
4. Visually check tires for proper inflation.
5. Test the Interlock System.
4.2 Interlock System __________________________________________________________
1. The Interlock System prevents the engine from starting
unless the parking brake is engaged, the traction pedal
is in neutral and the main reel switch is “OFF”. The sys-
tem also stops the engine if the operator leaves the seat
with the main reel switch “ON” with at least one individ-
ual reel switch “ON”, traction pedal out of NEUTRAL, or
parking brake “DISENGAGED”.
2. Perform each of the following tests to insure the
Interlock System is functioning properly. Stop the test
and have the system inspected and repaired if any of
the tests
fail as listed below:
the engine does not start in test 1;
the engine does start during tests 2,3 or 4;
the engine continues to run during tests 5 or 6.
3. Refer to the chart below for each test and follow the
check (
) marks across the chart. Shut engine off
between each test.
