Safety Instructions

⚠️ WARNING! When using electric tools, basic safety precautions should always be followed to reduce the risk of fire, electric shock, and personal injury. Read all these instructions before attempting to operate this product and save them for future reference.

1. The owner must ensure that only qualified persons operate, maintain, or repair this machine.
2. Before attempting any maintenance, switch off the motor and isolate it from the main power supply.
3. All portable electric appliances are dangerous if used incorrectly. This machine will only operate on 220-240 volts. Check the power supply to ensure it corresponds to the voltage indicated on the rating label.
4. It is advisable to always use a Residual Current Device ("RCD"), (earth leakage trip), plugged directly into the 230 volt socket. If using an extension cable, plug it directly into the RCD.
5. If using an extension cable, it must be no more than 20 metres in length, and the wire section must be 1.5 mm². Ensure the extension cable is carefully laid out, avoiding liquids, sharp edges, and vehicles running over it. Do not allow the cable to become trapped underneath the mixer. Unroll it completely so the cable does not overheat. Ensure the cable connections (plug and socket) are dry and safe.
6. When not in use, store this machine in a dry, locked place, away from children.
7. The 220-240 volt motor is IP44 protected.
8. Fitted with a NO VOLTAGE RELEASE switch: if the power supply fails, the machine will stop. Re-start the mixer by pressing the green button.
