The machine has a high pressure hydraulic circuit for the movements. The pressure in this
circuit can be adjusted by turning the handle (A, Fig. 15) as explained in the table.
Normal operating pressure adjustment range 80 to 180 bar.
The pressure at which the machine is set can be checked on the pressure gauge (C, Fig.
10) by operating the turntable open control to its end of stroke or by locking a rim.
NOTE.
When working with light alloy rims, it is recommended to use the specific clamps supplied
upon request (Fig. 16) in order to prevent scratching or scuffing the rim. To prevent the
rim from rotating on the clamps, a pin for alloy wheels must be inserted in one of the rim
fixing holes (A, Fig. 17).
WARNING
If the machine malfunctions, retreat to a safe distance and turn the machine's main
switch (A, Fig. 18) to 0.
WARNING
Make sure that the rim is correctly and firmly locked on every gripping point of the
turntable clamp.
WARNING
Any operation intended to increase the maximum pressure setting value of the relief
valves is forbidden.
The manufacturer declines all liability for damage resulting from tampering with
these valves.
The pressure should be reduced for weak or particularly thin rims; for thick rims that are
difficult to demount, it is recommended to adjust pressure to the maximum level.
Adjust the opening of the turntable using the "closing/opening" control (control 7 Fig.13)
based on the type of rim to lock (see examples in Fig. 19). If the rim exceeds 48" in the
locking point, or when considered appropriate, tip the clamps (Fig. 20).
Place the wheel in a vertical position in the machine locking zone (Fig. 21).
Use the controls to set the turntable so that the ends of the clamps just touch the rim
edge.
Then lock the turntable, selecting as the locking point the area that is as inward as pos-
sible depending on the form of the rim.
