MAINTENANCE
Practically the only machine’s part that can wear is the motor. Therefore its maintenance should be carried out very
carefully, which means that the air supply must be in dry & clean condition. For this purpose the following three points
must be taken into account:
1. Drain periodically the water collected in the left air treatment unit cup by pressing the relief knob (5b, page 35).
2. Fill up the right air treatment unit cup with special pneumatique motor oil, SAE-10.(light duty oil).
3. Make sure, by checking the sight glass (7b, page 35) that, when the machine is in operation, between 2 to 3 drops/min
are supplied. The regulation is made by means of the control knob (7b, page 35).
EXHAUST FILTER (REPLACEMENT)
Ref. 40202304
• Close the flowrate regulating valve (3b, page 35). Actuate the air-lever of the motor so that the internal air goes
out.
• Take out the intake tube and the reversing button (1, 4).
• Unscrew the raccord (2) situated on the upper side of the motor. Remove the external casing (3) and take out the
exhaust filter.
• Replace the exhaust filters.
• Reverse the process for the reassembling.
MOTOR PLATES (REPLACEMENT)
Ref. NH120846
1. Close the air inlet valve located on the left side of the air filtering unit and press the motor lever so that the air
goes out.
2. Remove the intake pipe and unscrew the raccord situated on the upper side of the motor.
3. In continuation, pull out the inversion button, remove the external casing and take out the exhaust filter.
4. Using a pin spanner, loosen the motor housing by unscrewing to the left.
Be careful with the steel ball that is housed inside the shell.
5. Remove the whole rotor assembly from inside the casing.
6. Pull out the “seeger ring” of the upper part of the motor and remove the upper head, the stator and the MOTOR
PLATES.
Notice the direction and positions of the motor stator and the top head.
CLEAN and BLOW OFF all parts before doing the assembly.
6a) If it is necessary to replace the motor bearings:
6b) Use a nylon hammer to separate the ball bearing from the rotor.
6c) Assemble the entire rotor unit again using two plates with a thickness between 0.6 and 0.8 mm positioned
between the rotor and the bottom head unit.
7. Lubricate the new motor plates with SAE-10 oil and mount them on their rotor seatings.
8. Place the motor stator in its right position, install the upper head together with its ball bearing and mount the
“seeger ring“.
9. Take the whole rotor assembly and insert it vertically and without turning it so that the rod is introduced into the
hole provided in the bottom of the motor casing. Once having placed the rod in its seat, screw the whole assembly
(LEFT-HAND THREAD) and tighten it with a pin spanner.
10. Mount again the exhaust filters and its casing, exhaust-cover.
11. Screw the intake raccord, install the inversion button and connect the air motor pipe
