Pneumatic Connection - Beta 1881 Instrucciones

Connecting the delivery pipe
• Use a ½" or ¾" pipe of very good quality which conform with DIN-SAE regulations, make sure it is
suitable to the pressure and to the liquid to be pumped.
• Connect one end of the pipe T to the outlet fitting R (Thread G ½ or ¾"spheric) of the pneumatic
pump.
• Connect the other end of pipe with delivery gun P (supplied on request as an accessory).

Pneumatic connection

• Make sure that the delivery pipe T is connected and the delivery gun P is switched off .
• Find a compressed air outlet where the following components are installed:
• Filter and steam trap.
• Air lubricator.
• Pressure reducing valve to adjust the pressure max 8 bar.
• Fast locking tap of compressed air to be used in the case of problems or emergency.
• The inlet I of the compressed air to the pneumatic motor is provided with a G1/4" thread. If a fast
clutch is used, make sure it is adequate to the pressure of the system.
• Warning: If the compressed air valve N is open the motor will start as soon as it has been
connected to the compressed air system.
First start with a new motor
Before starting the pump it is necessary to free the motor from protective grease which is applied
during assembly; therefore carry out the following operations:
• Take off the elastic stop ring of the silencer.
• Take silencer out of its seat.
• Cover air exhaust hole with a strong cloth to avoid any residues carried by the compressed air
hitting the user.
• Let the vacuum pump work for about 20-30 seconds.
• The sound level reached without the silencer requires the use of ear protection to protect hearing.
• At the end of the operation put the silencer back on and fasten it with the elastic stop ring
previously removed.
Oil delivery
If all operations previously described are properly carried out and the compressed air valve is open,
to start oil delivery it is sufficient to press the lever on the handle of the delivery gun P.
If the lever is released the pneumatic pump stops automatically.
Warning:
the delivery pipe is constantly under pressure.
