2.4 If necessary assemble the support/pivot
shaft to the Express Relief chassis.
Locate the chassis over the shaft as
shown, with the end of the shaft ush with
the outer chassis boss.
Position the two adjustable collars
as shown and secure in position with
the grub screws, to prevent lateral
movement of the chassis on the support/
pivot shaft.
2.5 Place the Express Relief on the lift table platform as shown (ensure that the bolts securing
the support/pivot shaft to the bracket go into the detents in the shaft).
2.6 Position the support bracket so that
it is central on the side plate of the
lift table chassis.
2.7 Mark the hole positions, using the
support bracket as a template.
Drill 8.5mm & Tap M10 (using the
drill and tap supplied).
Securely bolt the Express Relief to
the machine.

These instructions assume that the Express Relief has been correctly tted to the lift table
of an Express Dual according to the supplied tting instructions.
3.1 If the Express Relief is in its "lowered"
position, supported on the lift table
platform, lower the lift table platform to the
ground.
3.2 Slide the grinding head the left hand side of the guide
rail and pivot the Express Relief about its mounting, to the
vertical position and hold in position with the locking pin.
3.3 Place the cutting unit on the lift table, front facing away from the machine and raise the
platform so that the cutting unit can be slide onto the machine table.

3.5 Bring the cutting unit onto the Express
Relief so that it’s rear roller is located in the
‘V’ support.
3.6 Position the adjustable clamps in the
slotted side supports so that they can
be attached to an appropriate (solid and
secure) part of the mower frame to secure
the cutting unit, starting at an angle of
approximately 45 degrees.
3.7 Alternatively, secure with a suitable bolt
directly through the side supports to the
cutting unit or (if necessary, use the spacer
bosses provided).
3.4 Lower the lift platform around 4” (100mm),
remove the locking pin and lower the
Express Relief to the horizontal position.
Raise the platform to it’s highest position
once more to support the Express Relief
frame.

3.9 Loosen locking lever [C] to enable
horizontal infeed of the grinding head
using handwheel [D], Loosen locking lever
[E] to enable angular adjustment of the
grinding head.
3.8 Loosen locking levers [A] and raise
the guide rail by rotating adjusters
[B] at each end of the rail, for coarse
positioning of the grinding head relative
to the cutting unit.
3.10 Fine adjustment of mower position back
and forth can be achieved by moving the
vee support for the rear roller with the
handwheel.

3.9 Position the grinder so that a reel blade can
be “trapped” between grinding disc [F] and
support nger [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 ne 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 nger 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 rst blade that is ground, grind each blade in turn for one complete
revolution of the reel, then apply a ne nishing cut and repeat grinding for one revolution
of the reel in the opposite direction.
