Operating Safely

MIF

Only allow responsible adults, who are familiar with the instructions to operate the machine. Local restrictions may restrict the age of the operator.

Inspect machine before you operate. Be sure hardware is tight. Repair or replace damaged, badly worn, or missing parts. Replace faulty silencers. Be sure guards and shields are in good condition and fastened in place. Make any necessary adjustments before you operate.

Before using, always visually inspect to see that the

blades, blade bolts and the mower assembly are not worn and damaged. Replace worn and damaged blades and bolts in sets to preserve balance.

Be sure all drives are in neutral and parking brake is locked before starting engine. Only start engine from the operator’s position.

Do not change the engine governor settings or overspeed the engine. Operating the engine at excessive speed can increase the hazard of personal injury.

Do not operate mower without discharge chute or entire grass catcher in place. Never operate with the discharge deflector raised, removed, or altered, unless using a grass catcher.

Check brake action before you operate. Adjust or service brakes as necessary.

Stop machine if anyone enters the area.

If you hit an object or if abnormal vibration occurs, stop and inspect the machine. Make repairs before you operate. Keep machine and attachments properly maintained and in good working order.

Be aware of the mower discharge direction and make sure that no one is in the path of the discharge direction.

Do not leave machine unattended when it is running.

Only operate during daylight or with good artificial light.

Stop the blades rotating before crossing surfaces other than grass.

Use only accessories and attachments approved by the manufacturer of the machine. Keep safety labels visible when installing accessories and attachments.

Do not operate machine if you are under the influence of drugs or alcohol.

Check before each use that operator presence controls are functioning correctly. Test safety systems. Do not operate unless they are functioning correctly.

Always wear seat belt if machine has a standard ROPS or a folding ROPS in the upright position.

Never raise mower decks when blades are running.

Slow down and be careful of traffic when operating near or crossing roadways. Stop blades before crossing roads or sidewalks. Use care when approaching blind corners, shrubs, trees, or other objects that may obscure vision.

Do not wear radio or music headphones. Safe service and operation require your full attention.

Disengage drive to attachments when transporting or not in use.

Reduce the throttle setting during engine run-out and, if the engine is provided with a fuel shut-off valve, turn the fuel off at the conclusion of mowing.
