CARTRIDGE DOWN FORCE ADJUSTMENT
The Counterweight supplied is suitable for cartridges weighing between
3.0-6.0g. Gently push and turn the Counterweight onto the rear of the
tonearm (with the scale facing toward the front of the turntable).
Remove the cartridge protection cap. Lower the tonearm lift and position
the cartridge in the space between tonearm rest and platter.Carefully
rotate the Counterweight until the tonearm balances out. The tonearm
should return to the balanced position if it is moved up or down.
This adjustment must be done carefully.
The anti-skating force must be adjusted corresponding to the tracking
force as follows:
Tracking Force
5-10 mN
10-15 mN
15-20 mN
20mN and bigger
1st from bearing ring
2nd from the bearing ring
3rd from the bearing ring
4th from the bearing ring

Once the tonearm is correctly balanced return it to its’ rest. Hold the
Counterweight without moving it, and gently rotate the Down force Scale
ring until the zero is in line with black line on the rear of the tonearm.
Check whether the arm still balances out.
Rotate the counterweight counter clockwise (seen from the front) to
adjust the down force according to the cartridge manufacturer’s recom-
mendations. One mark on the scale represents 0.05g of down force.
NOTE: The recommended down force for the factory fitted cartridge is
