WARNING:

Never mow with dull blades! Blades that are bent should be replaced! The cutting blades are sharp and can cause severe injury. Wrap the cutting surface of the blade with a rag to avoid injury.

a.Set the parking brake.

b.Clean any debris from the blades. Keep blades sharp and free of build up at all times.

c.Sharpen blades evenly at the original 30° angle to maintain balanced cutting blades. Do not sharpen the underside of the blades. Use a electric blade sharpener, a conventional electric grinder or a hand file to sharpen the blades.

d.Replace any blade with severe nicks or dents that cannot be removed by filing.

e.Check the balance of the blade after sharpening by placing it on a blade bal- ancer. Do not use un-balanced blades.

f.If the blade dips on one end, file stock off of the cutting surface on that end.

Note: Blades that cannot be easily bal- anced—REPLACE.
