MAINTENANCE AND LUBRICATION 8

8.3.1 FLAIL CUTTING UNIT MAINTENANCE _________________________________

Daily Inspection

Check condition of the blades & hardware every day prior to cutting. Remove any debris or foreign objects from

around flail blades.

• Check the blade (A) and fixings are secure. Ensure the

Nut (D), bolt (C) and shackles (B) are securely attached.

• Check the blade for any damage and excessive wear of

both tip and mounting hole.

• Check the Shackle and Lugs (E) for damage and wear.

• Check unit enclosure and ensure guarding is not

damaged securely in place.

Weekly / 50 hour Inspection

• Check the blade fixing nuts are tight. If required tighten

nut and bolt to point where tabs flex. Check shackle can

rotate freely, if not loosen bolt until shackle can rotate.

• Blades can be sharpened if the edge is damaged. A

maximum of 5 mm (1/4inch) can be ground or filed off

the cutting edge before replacement is necessary

If a high quality finish of cut grass is desired, it is recommend that all blades be replaced as a set per unit. Any

individual blade replacements would require trimming to match length of existing blades. This will help maintain

an even and consistent height of cut.

When refitting or replacing flail blades, ensure the correct orientation of the bolt heads as indicated in diagram. It

is recommended that new fixing hardware is used when replacing worn or damaged blades.

1. Flails in position #1 to have bolt

heads facing towards the centre

line.

2. Flails in position #2 to have bolt

heads facing away from centre line

WARNING

Inspect and replace immediately any flails, lugs and retaining hardware that show any

indication of cracks, heavy damage or more than expected wear. Failure to replace

damaged parts can cause parts to be thrown out without warning. More than expected

wear or damaged parts will unbalance the rotor and cause lasting damage. When you

operate with an unbalanced rotor it will cause accelerated wear, increased vibration and

possible dangerous operator fatigue
