Adjusting tone arm and pick-up cartridge
 
Remove stylus guard carefully. Turn the anti-skating 
knob (2) counter-clockwise until it stops (Fig. 6). 
Screw the tonearm counter weight (3) onto the rear 
tonearm tube (Fig. 5). 
Unlock the tone arm (4) a bit towards the centre of 
the platter. Bring the lift-lever (5) into position 
while holding back the tone arm (Fig. 6). 
By turning the counter weight (3) the tone arm can 
be precisely balanced in order to make it hover 
freely above the platter. Move the tone arm back to 
its rest. 
You can now adjust the tracking force (1) and 
the anti-skating force (2). 
Hold tone arm counterweight and adjust tracking
