Position the grinder so that a reel blade can
be “trapped” between grinding disc
[F]
and
support finger
[G]
with the grinding disc
setting the required angle of relief to the blade.
Using the adjusting handwheels
[B]
at each
end of the guide rail, make fine adjustments
until contact between reel blade and grinding
disc is even along the length of the blade.
Lock this position using levers
[A]
.
Note
: Fine adjustments can later be repeated like
(with the grinder running) this to ensure an
equal width of land ground along the reel
blade.
3.10 With a suitable driver attached, insert the
reel control handwheel
[H]
into the cutting
unit so that each reel blade can be safely
held against the support finger and to allow
indexing from blade to blade.
3.11 Move the grinder to one end of the reel, back
the disc away from the reel blade slightly
using feed knob
[D]
, switch on the grinder.
Feed the grinder in to apply a reasonable cut
and tighten feed locking lever
[C]
.
3.12 Traverse the grinder back and forth along each reel blade, increasing cut as necessary,
until an acceptable amount of relief (blade thinning) has been applied.
Note: Ideally mark the first blade that is ground, grind each blade in turn for one complete
revolution of the reel, then apply a fine finishing cut and repeat grinding for one revolution
of the reel in the opposite direction.
