EXPRESS DUAL • ED2000

6.4 Set up of Traverse/Stops

Manual, bench-mounted machine

Rotate hand wheels anti-clockwise to move grinding wheel away from reel. Traverse the

grinding wheel by hand, using the handle xed to the fork-driver until it is at the extreme

point of desired travel (so that one edge of the grindstone is past the end of the reel but not

touching the mower’ side frame). Move the stop collar, on that side of the grinder, against

the fork driver. Move the grinding wheel to the opposite end of the desired travel and

repeat the operation.

Auto traverse machine with free standing support

Rotate hand wheels anti-clockwise to move grinding wheel away from reel. Unscrew the

traverse engagement screw until it is released from the traverse chain, traverse the grinding

wheel by hand, using the Traverse Engagement Screw until it is at the extreme point of

desired travel. Ensure that the traverse reversing bar (the shaft that the traverse pick up

and stop collars run on) is also moved in that direction and slide the reversing stop up to

the grinding wheel traverse assembly and tighten. Move the grinding wheel to the opposite

end of the desired travel and repeat the operation ensuring that the reversing bar has also

been moved in the opposite direction. This is critical where the grinding wheel cannot pass

beyond the end plates if they protrude below the maximum diameter of the reel.

NOTE On the EXPRESS DUAL it is not necessary for the whole width of the grinding wheel to

pass the end of the reel and it SHOULD NOT DO SO EVEN IF SPACE PERMITS (see

Fig. 6.4).

Ensure that the leading edge

of grinding stone passes the

end of the reel - but clearance

must be maintained between

stone and end frame of unit.

NOTE: The reversing bar will move approximately 1/2” (13mm) before the direction of travel is

reversed and will allow the grinding wheel to move with it. It is therefore ESSENTIAL that

this is taken into account when setting the maximum point of travel.

Should the reversing bar be dragged by the traverse assembly in the direction of travel

during the grinding processes, causing the stone traverse to reverse prematurely, it will be

necessary to adjust the reversing bar damper.
