19.2 Maintenance of the mortar mixer
The mixer is virtually maintenance-free. The spur gear unit of the three-phase motor and
the planetary gear unit of the mixer head are provided with sufficient lubrication for ap-
proximately 5,000 operating hours.
After several years of operation, a thorough cleaning and refilling of the gear units with
suitable lubricants is recommended.
Due to the very compact design of the mixer, we recommend that you use our mainte-
nance service.
19.3 Control and adjustment
Depending on the frequency of use of the mortar mixer, a check of the distance between
the mixer and mixing bowl is required (see point 6.8).
This distance is increased by normal wear of the mixer and may need to be readjusted.
19.4 Decommissioning the mortar mixer
1. Switch off the MAIN SWITCH, position "-0-" or "-OFF-"
2. Disconnect the mortar mixer from the mains supply
3. Cover the mortar mixer with the dust cover
4. Store the mortar mixer in a dry place
Caution
Safety advice!
1. Work on electrical equipment may only be carried out by qual-
ified personnel!
2. In the event of a fault and/or before disassembling covers, pull
out the mains plug!
Note

In the event of a fault, the mortar mixer must be disconnected from
the mains supply. After disassembling the upper and lower covers, the
safety fuses of the individual modules are accessible. These can be
checked and replaced with new, identical safety fuses if necessary.
