V. GENERAL MAINTENANCE
1. Dust only with a soft brush, do not blow away dust.
2. If the tonearm is mounted on a wooden armboard the base may need to be
retightened to the board after a few weeks.
Checking Tonearm Bearings for Play
Holding the headshell, gently try to rotate tube of arm. There should be no movement
or audible clicking. If there is, consult your dealer.
NOTE: Ensure that Azimuth and height adjustment screws are fixed before
attempting the above.
Checking Tonearm Bearings for Friction (Fig. 26)
1. Replace stylus guard and balance tonearm with bias at minimum. The arm should
move slowly and smoothly from the inner groove towards the armrest.
2. Add tracking force of 0.1 gram. The tonearm should now go slowly down and
outwards towards the armrest.
3. Balance tonearm again and set tracking force to -0.1 gram. Now the tonearm should
move slowly up and out towards armrest.
4. If the tonearm does not behave in this way, repeat tests before consulting your
dealer.
NOTE: Ensure that tube movement is unobstructed by the cueing device.
