Checking the Safety System

The machine is equipped with a safety system that prevents starting or driving under the following conditions.

The engine can only be started when:

1.The blades are disengaged.

2.The neutral bail must be in the locking position.

Make daily inspections to ensure that the safety system works by attempting to start the engine when one of the conditions is not met.

If the machine starts when one of these conditions is not met, turn the machine off and repair the safety system before using the machine again.

Functional check

Check the function of the safety electrical system on a regular basis.

1.Engine must stop if blades are engaged without operator presence levers held down.

2.Engine must stop if neutral bail is taken out of neutral without holding down operator presence levers.

3.Engine must not start unless blades are off and neutral bail is in the neutral position.
