A3.2.2. Speed higher than usual
- Speed of descent regulator (screw nº 5)
The screw may be excessively tightened  Turn the regulator loosen it until achieving the desired speed.
- Safety gear valve test regulator (screw nº 9)
The screw may be tightened to the limit (if the safety gear valve operates)  Turn the regulator loosen it completely.
A3.3. Levelling speed (does not work or does not reach the correct speed)
- The reasons that cause the malfunctioning of the levelling speed in ascent are considered the same for the levelling speed in descent. On top of this there
are some other reasons for not reaching the correct levelling speed in descent.
- Safety gear valve test regulator (screw nº 9)
- Check that the screw is not tightened as it could cause an excessively high levelling speed.
 From a completely tightened position, turn the screw three times to untighten it.
- Speed of descent regulator (screw nº 5)
- Check that the filter and the jet where pressure enters the equalizer (free piston cap) is not blocked.
 Open the aforementioned cap and check it at this point.
- Levelling speed regulator (screw nº 4)
- If the levelling screw is too tight, the lift will not descend smoothly but with bumps.
 Loosen the screw and adjust to the desired speed.
- If the levelling screw is untightened too far, there will be problems in the levelling (it will not stop at the floor).
 Loosen the screw and adjust to the desired speed.
