Backlapping - Jacobsen G-Plex III Sicherheits-, Betriebs- Und Wartungshandbuch

10 ADJUSTMENT

10.10 BACKLAPPING

This mower is fitted with a device to allow the reels
to be driven in reverse for backlapping.
• Backlapping is a process which will lightly
grind the reel to the bedknife whilst mounted
on the mower.
• If significant amounts of metal are to be
removed then the cutting unit should be
reground on a specialised grinding machine.
• Before any backlapping is carried out,
Ransomes Jacobsen recommends that the
backlapping process should be risk assessed
as a workshop process by the manager of the
machine.
• Backlapping should only be carried out by
trained staff.
• Ransomes Jacobsen recommend that
grinding paste is only applied to the reel when
it is stationery, the engine is off and the
parking brake applied.
• When applying grinding paste the reel should
only be rotated by appropriately sized piece
of wood and not by hand.
• Place reels in the most accessible position for
applying the paste.
• Leave the grass boxes in position on the
cutting units as a safety barrier.
• After applying the grinding paste the person
backlapping should return to the seat, engage
the relevant controls and run the reels in
reverse.
• When the desired finish is achieved switch
off the mower, clean off any surplus paste,
reset the reel to bedknife and return the
controls to the normal mow positions.
