Keep clear of the discharge opening at all times. Stop blade motion when crossing gravel drives, walks or roads and under all conditions where thrown objects might be a hazard. The blade can be stopped through the use of the blade brake. After striking a foreign object, stop engine, remove wire from spark plug, thoroughly inspect mower for any damage, and repair damage before restarting and operating the mower. If the equipment should start to vibrate abnormally, stop the engine and check immediately for the cause.
Vibration is generally a warning of trouble.
Before inspecting, cleaning or repairing mower, make certain blade and all moving parts have stopped. Disconnect engine spark plug wire and secure away from plug to prevent accidental starting. DO NOT run the engine indoors. Shut the engine off and wait until the blade comes to a complete stop before unclogging discharge chute. Keep all nuts, bolts and screws tight to be sure mower is in safe operating condition.
