(Continued)
8.1.6 USING THE “C” SPANNER PROVIDED, loosen the retaining nut.
8.1.7 Remove the circlip retaining the left hand side arm to the rear shaft. The side arm can now
be removed from the machine.
8.1.8 The grinding wheel and sleeve can now be withdrawn. Remove the retaining nut and the
old wheel. Clean sleeve and nut thoroughly.
8.1.9 Fit the new grinding wheel and replace the collar, ensuring that all mating services are
clean and undamaged.
8.1.10 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.
8.1.12 Loosen the small allen key in the reel drive support block, pull the diamond dresser out a
short way and re tighten the screw.
8.1.13 With the stone NOT running, bring the mainshaft (and grind-stone) up horizontally.
Manually traverse the ‘stone past the diamond, making a light scratch, to confirm that the
shaft is horizontal.
8.1.14 Move the stone just clear of the dresser then start the grind motor.
8.1.15 Bring up the shaft equally on each side and manually traverse the ‘stone across the
dresser.
8.1.16 Switch on and engage the auto traverse with the stops set so that the stone completely
passes the dresser back and forth.
8.1.17 Apply more feed as necessary to true the stone.
NOTE
Dressing in this way should be carried out periodically to keep the ‘stone clean and true
BUT remove only the minimum material off the stone to keep long service.
