8. Maintenance
(Continued)
8.1.7 The grinding wheel and sleeve can now be withdrawn. Remove the retaining nut and the
old wheel. Clean sleeve and nut thoroughly.
8.1.8 Fit the new grinding wheel and replace the collar, ensuring that all mating services are
clean and undamaged.
8.1.9 Ensure that the mainshaft and sleeve are perfectly clean and dry. Reassemble in the
reverse order ensuring that when you replace the grinding wheel assembly onto the
mainshaft, the nut is on the LEFT HAND side when viewed from the operator’s position
(Tighten nut whilst assembly is on the mainshaft).
NOTE Be careful to guide the assembly into the fork when lowering the mainshaft. Make sure that
the left hand side arm is centered in the channel before tightening the screws that lock the
bearing inner to the shaft.
8.1.10 Loosen the small allen key in the reel drive support block, pull the diamond dresser out a
short way and re-tighten the screw.
8.1.11 With the stone NOT running, bring the mainshaft (and grindstone) up horizontally.
Manually traverse the ‘stone past the diamond, making a light scratch, to confirm that the
shaft is horizontal.
8.1.12 Move the stone just clear of the dresser then start the grind motor.
8.1.13 Bring up the shaft equally on each side and manually traverse the grindstone across the
dresser.
8.1.14 Switch on and engage the auto traverse with the stops set so that the grindstone
completely passes the dresser back and forth.
8.1.15 Apply more feed as necessary to true the grindstone.
NOTE Dressing in this way should be carried out periodically to keep the grindstone clean and
true BUT remove only the minimum material off the grindstone to keep long service.
