A2.3. Levelling speed (does not function correctly)
- Speed change screen (Magnets on guiderails).
- The pulse magnets used for carrying out a change of speed are incorrectly positioned Alter their distance.

- Hydraulic oil.
- The temperature of the oil may be too low (below 5º C) meaning that the lift may not be able to change speed.
It is necessary to install a tank-heating element (or check its performance if one is already installed).
- Deceleration regulator (screw nº 3).
- The screw may be excessively tightened and the lift may change speed very slowly Turn the regulator to open it in the direction indicated by the arrow.
- The screw thread may be broken and not act as a regulator Check.
- Check the state of the filter and the intake port for the regulator screw nº 3 Take it out and clean it if required.
- Speed change electrovalve (YR).
- The coil does not connect Check the connection in the connector and in the control panel terminal.
To check that there is no excitation in the coil, place a screwdriver on the upper part to perceive any force of attraction.
- The electrovalve actuator is blocked the oil returns to the tank via the YR electrovalve sheath.
- The position of the ball on the base supplement or on the base of the electrovalve may be damaged.
Clean any possible shavings or impurities.
Place the ball catch on the mechanized cone at the base of the electrovalve.
