13. ROUTINE MAINTENANCE

WARNING!
Before making any inspection, adjustment or repair be certain
power source is disconnected:
1) disconnect the machine from the mains electric supply.
2) disconnect the machine from the compressed air circuit by
detaching the compressed air line from the quick couple.
Perform the following routine maintenance operations:
1) From time to time (about every 15 days) check the oil level in the lubricator, which should
be between the "MIN" and "MAX" indicators on the jar (1, Fig. T/1).
Top up as needed as follows:
- Unscrew the jar (1, fig. T/1)
- Top up with ISO VG 32 viscosity ISO HG class oil for compressed air circuit (such as ESSO
Febis K32; Mobil Vacouline Oil 1405; KLUBER Airpress 32).
2) Every 2 or 3 days check if after every 2 or 3 pedal movements (3 or 5, Fig. E) a drop of
oil falls into the lubricator glass cup.
If it does not, adjust the lubricator regulating screw using a screwdriver (see Fig. T/1).
3) Clean the machine daily to remove any dirt or tyre debris from the wheel clamp jaw
slides.
Lubricate these slides using ISO VG 68 viscosity ISO HG class grease (such as, for example
ESSO Febis K68; Mobil Vactra 2; Shell Tonna Oil 68).
4) To ensure correct operation of the inflation device pressure limiter (Refer to the section
on "SAFETY DEVICES", of this manual), it is essential to carry out the following routine
checks:
- Check the water level in the water trap to the air supply (2, Fig. T/1), which must NEVER
exceed the "MAX DRAIN" level indicator on the water trap itself.
When necessary, drain the water by turning the locking ring (3, Fig. T/1) clockwise.
- Every 30-40 days disconnect the machine from the compressed air circuit and dismantle
the glass (2, Fig. T/1) to remove any solids collected inside it.
5) After cleaning thoroughly with light fuel oil, LUBRICATE the arm travel ways (see Fig.
T/2) regularly, using a specific paste (type OKS 250).
6) If the exagonal arm does not descend as required, it can be adjusted by turning the
screw (1, Fig. T/3):
- turning the screw clockwise increases the descent speed;
- turning the screw anticlockwise reduces the descent speed;
N.B.: This adjustment is important when working on alloy rims that could be damaged if
the head descends rapidly.
