the main electrical supply, or remove the power lead from its socket.

1.4 NOISE - Owing to the widely varying conditions of use, noise emissions may vary

considerably. There may be occasions when the safe noise level may be exceeded (see

note on noise emission). In this case adequate ear protection MUST be worn.

1.5 NEVER t or use a grinding wheel (or other spares) other than those supplied specically

EXPRESS RELIEF

2.1 Check the height of the lift table platform – relative to the machine table.

If it is higher, as shown left, it will need to

be adjusted.

2 . 2 Undo the two wing knobs and remove the

cover from the lft table mechanism.

2.3 Using an ‘allen’ key in the adjusters, adjust

the chain length so that the platform and

the machine table are level.

2. Installation

EXPRESS RELIEF

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.

EXPRESS RELIEF

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. User Instructions

EXPRESS RELIEF

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.

EXPRESS RELIEF

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.

EXPRESS RELIEF

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.
