Safety

Use extreme care when loading or unloading the machine into a trailer or truck.

Use care when approaching blind corners, shrubs, trees, or other objects that may obscure vision.

Slope Operation

Use Extreme caution when mowing and/or turning on slopes as loss of traction and/or tip-over could occur. The operator is responsible for safe operation on slopes.

DANGER

Operating on wet grass or steep slopes can cause sliding and loss of control. Loss of control and/or loss of operator's footing could result in a fall with an arm or leg getting under the mower or engine deck which may result in serious injury, death or drowning.

Mow across slopes, never up and down.

Do Not mow slopes when grass is wet.

Do Not mow near drop-offs or near water.

Do Not mow excessively steep slopes.

Reduce speed and use extreme caution on slopes.

Avoid sudden turns or rapid speed changes.

When feasible, avoid operating the equipment in wet grass.

Progressively greater care is needed as the slope increases.

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.

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

Maintenance and Storage

Stop the engine and remove the spark plug wire(s). 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.

Remove spark plug wire before making any repairs.

Use care when checking blades. Wrap the blade(s) or wear gloves, and use caution when servicing them. Only replace damaged blades. Never straighten or weld them.

Keep hands and feet away from moving parts. If possible, Do Not make adjustments with the engine running.

Keep all guards, shields and all safety devices in place and in safe working condition.

Check all bolts frequently to maintain proper tightness.

Frequently check for worn or deteriorating components that could create a hazard.

WARNING

Removing standard original equipment parts and accessories may alter the warranty, traction, and safety of the machine. Failure to use original Exmark parts could cause serious injury or death. Making unauthorized changes to the engine, fuel or venting system, may violate EPA and CARB regulations.

Replace all parts including, but not limited to, tires, belts, blades, and fuel system components with original Exmark parts.
