Mechanical fault
8. Periodic maintenance and cleaning
The unit must only be operated when in perfect condition!
Immediately shut down the unit as soon as any damage or malfunction is detected!
Danger!
• Only open the control unit and carry out maintenance work on the entire machine when the mains plug is disconnected!
• The unit must always be secured against falling or toppling over while being installed, repaired or maintained – risk of fatal injury!
• Place a retaining strap around the rod end and secure with a lifting device!
Caution!
Risk of physical injury to people and animals and material damage!
• Maintenance and cleaning work must only be carried out by trained personnel.
• Keep all safety and warning notices on/at the unit in a legible condition at all times.

8.2 Visual inspection of mechanical + electrical safety technology
• Daily inspection of the unit for externally visible damage and general functionality.
• Check of the status of the electrical cables and the control unit. (Bite marks, wear spots, loose connections, etc.).
8.3 Gears
The gears have already been filled at the factory with Shell Tivela S320 gear oil. Top up any lost oil using only this type of oil. Check whether oil is
leaking from the gearbox seals.
8.4 Screw connections
Check all screw connections weekly to ensure they are tight, especially the securing of the unit to the wall. Tighten the screw connections if neces-
sary.
8.5 Moving parts
Lubricate the bearings and bushings (Fig. 9) monthly. These parts must be inspected regularly and replaced if they are wearing too much.
Cause
The brush does not swing cleanly up
and down.
The gears are turning, but the brush
is not
Corrective measure
• Foreign body between the housing parts or in the bearing bet-
ween the motor housing and external housing.
• Remove the foreign body.
• Bearing bushings (Fig. 11, item 44) are worn or faulty.
• Replace faulty and worn parts.
• The clamping pins between the plastic shaft and the motor drive
shaft have sheared off.
• Replace the clamping pins.
