BACKLAPPING OPERATION
NOTE
The Applicator Brush must be free of grease or oil.
•Apply Grinding Compound to the Reels and allow two minutes for it to ‘work in’.
•Spray a fine ‘mist’ of water onto the Reels and allow a further two minutes for it to ‘work in’.
•Apply a second application of Compound, followed by water ‘mist’.
•Continue this process until the Reels and Bedknife are sharpened satisfactorily.
IMPORTANT
When carrying out the above procedure, it may be necessary to adjust the Reels to maintain correct Reel to Bedknife contact.
When Backlapping is completed, use a pressure washer to thoroughly clean all Compound from the Reels and Bedknives. Failure to do so will have a reverse effect, as the Reels rotate in their normal direction, and the Blades could be damaged
Remove the Backlapping Unit from the Mower. Connect the Hydraulic Hoses, to the correct ports in the tractor.
Before using the Mower ensure that all Compound has been removed from the Reels and Bedknives.

The Backlapping procedure should be done once or twice each month, depending on the hours of operation, and if the Reels and Bedknives are not sharpened annually.
If the Reels and Bedknives are sharpened at least once each year, Backlapping should be done every six weeks.
If any Reels or Bedknives are badly scored it may be necessary to use a ‘Course Grit Compound’ to obtain a satisfactory result. Compound is available in 50, 80,120 and 180 Grit, for varying conditions.
NOTE
The 120 Grit is used for average or normal conditions. Coarser 80 Grit can be used for Reels and Bedknives that are in poor condition. The 50 and 180 Grit are at the extreme ends of conditions.
