Oil Pressure Light

Refer to Figure 2-2:

This light comes on when the ignition switch is placed in the RUN position and stays lit until the engine is running and a safe oil pressure is developed. If light comes on during operation, shut engine off immediately, locate and correct the problem.

Electronic Hour Meter

Refer to Figure 2-7

The hour meter is located on the right side behind the seat and registers in 1/10 hour increments up to 9,999.9 total hours. Connected to the ignition switch, the meter records the accumulative time while the ignition key is switched to the RUN position and the operator is on the seat.

Safety Start Interlock System

The mower is equipped with a safety start interlock system consisting of park brake switches, seat switch and blade engagement switch.

Check mower safety start interlock system each day prior to operation. This system is an important mower safety feature and should be repaired immediately if it is malfunctioning. The mower incorporates a separate seat switch which will stop the engine whenever the operator is unseated while the mower is moving or the blades are engaged. This safety feature is designed to prevent runaway or accidental entanglement. Inspect the system as follows:

1.The operator must be on the seat when testing the seat switch.

2.Set both control levers in the park brake position.

3.Start the engine and allow it to warm up to operating temperature.

4.A person should be able to slowly raise off the seat without the engine stopping if the blade engagement switch is down and the control levers are in the park brake position.

5.The engine should stop within two seconds if a person raises slowly off the seat and either the blade

engagement switch is up or the control levers are in neutral position.

6.Check the function of the seat switch If the engine fails to stop when the blade engagement switch is up or if one or both of the control levers are in and the operator is off the seat. Replace the seat switch If the seat switch is not operating properly (i.e. switch is not opening and/or closing).

If the problem cannot be located, contact your Land Pride Dealer.

!WARNING!

The safety interlock system should always function per steps 4 and 5. If it does not function properly, it should be corrected immediately. Do not operate machine without a properly functioning seat safety switch.

Engine Starting

The Razor Pro safety start interlock system is also designed to protect the operator and others from accidental injury due to unintentional engine starting. The engine starting motor will not engage until the following two criteria are meet:

Control levers are in the brake position.

Blade engagement switch is in the down (OFF) position.

!WARNING!

The safety interlock system must not be disconnected or bypassed.

NOTE: The operator’s seat is equipped with a separate safety switch. If for any reason the operator should become unseated when the neutral switches are disengaged or the blade engagement switch is engaged the engine will stop.

The following steps are the correct procedures for starting the engine. If difficulty is encountered, contact the Land Pride Dealer in your area.

1.Before starting mower each day, perform daily pre-operation checking. (See “Safety Start Interlock System” on this page.)

2.Make sure the control levers are in the brake position and blade engagement switch is disengaged.

3.Set throttle at approximately 1/2 open position.

NOTE: Use choke position when engine is cold, or if warm engine fails to start within 5 seconds of cranking. Avoid flooding and operate engine without choking as soon as possible.

4.Insert key in ignition switch and rotate clockwise to engage starting motor. Release key when engine starts.
