Safety

CAUTION

If the ignition is in the “ON” position there is potential for sparks and engagement

of components. Sparks could cause an explosion or moving parts could accidentally engage causing personal injury.

Be sure ignition switch is in the “OFF” position before charging the battery.

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, or using non-Exmark replacement 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.

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

WARNING

Hydraulic fluid escaping under pressure can penetrate skin and cause injury. Fluid accidentally injected into the skin must be surgically removed within a few hours by a doctor familiar with this form of injury or gangrene may result.

If equipped, make sure all hydraulic fluid hoses and lines are in good condition and all hydraulic connections and fittings are tight before applying pressure to hydraulic system.

Keep body and hands away from pinhole leaks or nozzles that eject high pressure hydraulic fluid.

Use cardboard or paper, not your hands, to find hydraulic leaks.

Safely relieve all pressure in the hydraulic system by placing the motion control levers in neutral and shutting off the engine before performing any work on the hydraulic system.
