OPERATION
7.11 BACKLAPPING _______________________________________________________
This mower has the ability to allow the reels to be driven in a reverse direction to sharpen the blade on the reels.
•
Backlapping is a procedure which grinds the reel to the bedknife with the unit mounted on the mower.
•
To remove a large amount of metal from the cutting unit it must be reground on a grinding machine.
•
Before you backlap the reels, the manager of the machine must calculate the level of risk to make sure that
the procedure is safe.
•
Backlapping must be done by approved personnel.
•
You must not apply grinding paste to the reel until it has stopped, the engine is turned off and the parking
brake is applied.
•
When you apply grinding paste, the reel must be rotated by a piece of wood and not with your hand.
•
Put the reels in the most accessible position to apply the grinding paste.
•
When you apply the grinding paste the driver must return to the seat, engage the related controls and run
the reels in reverse direction.
•
When you have ground a sharp edge on the blade, turn off the mower and remove any remaining grinding
paste. Set the reel to run in a forward direction and return the vehicle controls to the normal cut positions.
