• To adjust the skate pressure two adjusting screws /Á are available.
The knurled screw on the top is suitable for the ne-adjustment.
Via a leaf spring this screw presses against the upper skate suspension and trans-
mits the power for the skate pressure. Furthermore the screw position is used as an
indicator  for the adjusted pressure.
$The pressure of the skate should be as little as possible, but high enough to assure
a steady picture on the screen. General you can hear if the lm skate pressure is
adjusted correctly or not:
- If the pressure is too low the lm runs with a bad picture steadiness and a crackled
noise.
- If the skate is adjusted correctly the lm runs with an even running noise.
- If the skate is adjusted too strong the lm runs with a loud running noise and
the frame steadiness will get worse.
