Sart-Up - MP sava3 Technical Manual

1.7. Sart-up

1. The oil supply line (flexible hose or steel pipe) should be as short as possible and without sharp bends.
2. Make sure the pipe is in line with the connection and the joints are made as indicated in the technical manual.
3. Before assembling the pipe line, make sure the pipes are smooth and deburred. Clean the inside of the pipes with a lint free rag.
4. Loosen the air bleeder screw in the cylinder head.
5. Rotate the pump at low speed until oil comes out of the air bleeder hole. Then close and tighten the oil bleeder screw.
6. During the installation, repeat the bleeding operation to remove any accumulated air.
NOTE:
• Before pouring oil into a tank which may have been exposed to excessive humidity or opened to the air, remove the cover and check there are no trace of
moisture. Dry out the tank if necessary.
• Switch on the motor to check the turning direction. If the noise coming from the unit is excessive, the motor may be turning in the opposite direction.
• If the temperature of the machine room is very cold or very wet, the oil has to be heated.
• The manometer should be connected only when used by the installer.
• Check the rupture valve.
• After all adjustments have been made, seal the caps of all the valves.
NOTE:
• YS  the name of this valve is defined by the chosen configuration equipment. Then it will be:
- Y-D Electrovalve.
VERY IMPORTANT
The factor service of our motors is 40%. Consequently, in inspection speed, you have to remember that, during one minute time, the lift will be working for
20 seconds and resting for 40 seconds.
In the same way, during any t time period, it will be working for 0,4 t and resting for 0,6 t.
1.8 Wiring of Magnetic Sensors.
