To adjust the amount of pressure, carefully move the counterweight (4) along the support rod (44), until the stylus pressure is sufficient to raise the pressure gauge to the level position. Moving the counterweight (4) towards the cartridge will reduce pressure and away will increase pressure. Finally secure the counterweight (4) using hexagonal key provided.
