9.
Move the arm (and cartridge) over the correct place on the scales to be weighed
and lower the cartridge on to the scales
10. If the weight is too much, raise the arm and slide the counterweight back a little. If
it is too light, slide the counterweight forward a little
11. Repeat the step 10 until the cartridge manufacturer's recommended tracking
weight (down-force) is achieved and then return the arm to its rest and close the
arm retaining clip and nip the grub screw up on the counterweight
12. Remove the scales but keep to hand as they will be required again and replace the
mat on to the platter if it was previously removed
13. Put a record on the turntable. Do not turn the turntable on yet
14. Remove the arm alignment protractor from the arm box and gently lower the
arm and cartridge on to the record about 1 or 2 cm's from the beginning without
switching the turntable on
15. Look across the turntable/arm/cartridge from the right and with the alignment
protractor help up parallel along its length behind the arm on the record, check if
the arm tube is parallel with the horizontal lines on the alignment protractor. The
arm needs to be parallel to the horizontal lines on the alignment protractor and
therefore with the record when it is being played.
16. Return the arm to its rest and close the arm retaining clip

17. To adjust the arm height and to achieve it being parallel when playing a record,
hold the bearing seat/arm lift assembly plate (not the arm carrier) and loosen the
two grub screws in the arm collar and raise or lower the pillar of the assembly as
required and then secure in place by nipping up one of the arm collar's grub screws
18. Repeat steps 15, 16 and 17 until the correct height is achieved and then tighten
both grub screws in the arm collar
19. Remove the record from the turntable and place the alignment protractor flat on
the mat/platter with the spindle through the hole in the protractor (point 'O')
printed side up
20. Bring the arm and cartridge across the protractor and lower
on to the outer of the alignment grids (point 'C') with the
stylus tip falling inside the small circle in the middle of the
grid.
21. The cartridge and arm's front edges should be parallel to
each other and parallel within the grid when the stylus tip is
within the small circle when viewed from above
22. To adjust, loosen the cartridge bolts and slide backwards
or forwards as required ensuring that before each
measurement, the cartridge and arms front edges are
parallel to each other and the cartridge bolts are nipped
up – this may need to be repeated a few times to achieve
correct alignment
23. Once achieved, bring the arm and cartridge across the
protractor and lower on to the inner of the alignment grids
(point 'D') with the stylus tip falling inside the small circle in
the middle of the grid and repeat step 22 to achieve correct
alignment
