1.Safe Zone-Use the mower here on slopes less than 15 degrees

2.Danger Zone-Use a walk behind mower and/or hand trimmer on slopes greater than 15 degrees, near drop-offs and water.

Remove or mark obstacles such as rocks, tree limbs, etc. from the mowing area. Tall grass can hide obstacles.

Watch for ditches, holes, rocks, dips and rises that change the operating angle, as rough terrain could overturn the machine.

Avoid sudden starts when mowing uphill because the mower may tip backwards.

Be aware that operating on wet grass, across steep slopes or downhill may cause the mower to lose traction. Loss of traction to the drive wheels may result in sliding and a loss of braking and steering.

Always avoid sudden starting or stopping on a slope. If tires lose traction, disengage the blades and proceed slowly off the slope.

Follow the manufacturer’s recommendations for wheel weights or counter weights to improve stability.

Use extreme care with grass catchers or attachments. These can change the stability of the machine and cause loss of control.

Using the Rollover Protection System (ROPS)

A Rollover Protection System (roll bar) is installed on the unit.

WARNING

There is no rollover protection when the roll bar is down. Wheels dropping over edges, ditches, steep banks, or water can cause rollovers, which may result in serious injury, death or drowning.

Keep the roll bar in the raised and locked position and use seat belt.

Lower the roll bar only when absolutely necessary.

Do Not wear seat belt when the roll bar is down.

Drive slowly and carefully.

Raise the roll bar as soon as clearance permits.

Check carefully for overhead clearances (i.e. branches, doorways, and electrical wires) before driving under any objects and Do Not contact them.

In the event of a rollover, take the unit to an Authorized Service Dealer to have the ROPS inspected.

Maintenance and Storage

Disengage drives, lower implement, set parking brake, stop engine and remove key or disconnect spark plug wire. Wait for all movement to stop before adjusting, cleaning or repairing.

Keep engine and engine area free from accumulation of grass, leaves, excessive grease or oil, and other debris which can accumulate in these areas. These materials can become combustible and may result in a fire.

Let engine cool before storing and Do Not store near flame or any enclosed area where open pilot lights or heat appliances are present.

Shut off fuel while storing or transporting. Do Not store fuel near flames or drain indoors.

Park machine on level ground. Never allow untrained personnel to service machine.

Use jack stands to support components when required.

Carefully release pressure from components with stored energy.

Disconnect battery or remove spark plug wire before making any repairs. Disconnect the
