8 DIAGNOSIS OF PROBLEMS
The RE-BAR tier will eventually need maintenance service and replacement of worn parts due to normal wear and
tear.
Troubleshooting and/or repairs are only to be carried out by authorised dealers or specialists.
The RE-BAR tier warns about malfunctions using beep sounds.
If one of the problems listed, set the main switch to 0 position, before trying to solve the issue.
When the main switch is set to 1 - do not place your fingers near the curl guide or other moving parts of the
machine. If the problem still occurs, contact your dealer.
