Operation – the need for care and concentration when working with ride-on machines; – control of a ride-on machine sliding on a slope will not be regained by the application of the brake. The main reasons for loss of control are: ◊ insufficient wheel grip; ◊ being driven too fast; ◊ inadequate braking; ◊ the type of machine is unsuitable for its task; ◊ lack of awareness of the effect of ground conditions, especially slopes; ◊ incorrect hitching and load distribution.
Using the Rollover Protection System (ROPS) • Never operate the machine with damaged guards, shields, or without safety protective devices in place. Be sure all interlocks are attached, adjusted properly, and functioning properly. • Keep the roll bar in the raised and locked position and use the seat belt when operating the machine • Be certain the seat belt can be released quickly in the event of an emergency. • Be aware there is no rollover protection when the roll bar is down.
• Carefully release pressure from components with stored energy. • Disconnect battery before making any repairs. Disconnect the negative terminal first and the positive last. Reconnect positive first and negative last. • Use care when checking the blades. Wear gloves and use caution when servicing them. Only replace blades. Never straighten or weld them. • Keep hands and feet away from moving parts. If possible, do not make adjustments with the engine running.

This machine produces sound levels in excess of 85dBA at the operators ear and can cause hearing loss through extended periods of exposure. Wear hearing protection when operating this machine. Figure 27 1. Transmission check valve by–pass pins (2) Adequate rear weight is necessary to prevent the rear wheels from leaving the ground. Do not stop suddenly while deck or implement is raised. Do not travel down hill with the deck or implement raised. If the rear wheel leaves the ground, steering is lost. 3.
The module is divided into inputs and outputs. Inputs and outputs are identified by yellow LED indicators mounted on the printed circuit board. Output circuits do not determine output device integrity so electrical troubleshooting includes output LED inspection and conventional device and wire harness integrity testing. Measure disconnected component impedance, through wire harness (disconnect at SCM), or by temporarily “test energizing” the specific component.
