4 SAFETY DEVICES
The tire changer has a number of safety devices designed to guarantee the utmost operator safety:
1. Check valve on the spindle opening hydraulic line (inside the swivel connector, see fig. B/1). This prevents the wheel from falling from
the spindle if the hydraulic line is accidentally broken.
2. Pressure relief valve factory set at 1.885 PSI (130 bar ±10%) (See Fig. B/2).
This limits the pressure in the hydraulic circuit and ensure correct operation of the plant.
3. Pump motor overload shut-out (inside the electric enclosure).
This provides automatic shut-off for the motor to prevent damage from overheating.
