Setting the Tracking Force and Tonearm Height
Tracking force is adjusted by moving the tonearm counterweight forward and back on its shaft. If
your cartridge is heavy and the counterweight is all the way back, you can order a heavier weight
from your dealer.
The JMW-9T Tonearm does not have a built-in tracking force gauge. We recommend that you use
a Shure Stylus Force Gauge or good digital gauge.
Place the gauge on the platter (no record)
Loosen the set screws in the base of the tonearm and raise the arm so it looks parallel to
the platter when it is on the stylus force gauge. To adjust the arm height, loosen the
setscrews on the base of the arm assembly and turn the adjustment wheel above the
base. When the arm is at the desired height, tighten the screws.
If you do not raise the arm when doing this you will be between .2 to .4 grams light when
you are on the record. THIS IS VERY IMPORTANT!!
Follow the gauge instructions and set the tracking force according to the cartridge
manufacturer’s recommendation. We recommend always going to the high side of tracking
force. High frequency vibrations on a light-tracking cartridge can cause more damage to
the grooves of a record than running a cartridge at a heavy setting.
Put a record on the platter and lower the arm so it is parallel to the record. Now you will
be tracking at the force you set and not a lighter force.
