Safety
Understanding does not make every repair safe to perform.
CASECHO guides support diagnosis and preparation, but some work requires a qualified technician.
220V work requires competence
Disconnect the machine before inspection. Never work on an energised mains circuit. Replacement of a relay, heater, mains cable or protective device must be performed by a competent person under local electrical rules.
12V batteries
A battery can cause a short circuit, fire or release gas. Respect polarity, use suitable protection, avoid exposed conductors and keep the battery stable, ventilated and away from children.
The manual takes priority
Terminals, voltages and setup sequences vary by model. The diagram and manual supplied with the equipment take priority over a general guide. If uncertain, stop the machine and seek qualified help.
