3. Open safety guard, rotate the beater by hand and
measure the distance between the beater and the
bowl.
Adjustment:
4. To access the bowl arm guide plate (A), remove the
rear cover.
5. Loosen the screws (B) and move the bowl arm guide
plate in the required direction. Again turn the beater
and measure the distance between beater and bowl.

Replacement of Lifting Actuator
Bowl arms not loaded are moved to the upper position.
Bowl arms are moved down to a suitable relief support
established approx. midway.
ATTENTION HIGH WEIGHT!
The bowl arms
must be safely unloaded before the lifting
actuator is dismantled.
• Turn off the power to the machine at the switch on the
back of the machine
• Dismantle the three connectors for the switches on the
lift actuator
• Dismantle the cable for lifting actuator
• The lifting actuator is dismantled from the bowl arms by
removing the pin bolts
• Lift the actuator out of the machine
• Install the new actuator, if the lower actuator bracket
is replaced, use Loctite 638 to lock the bracket
• Power on the machine
• Then follow the section “Fine adjustment actuator
switches”
Replacement of actuator switches
There are 3 switches on the lift actuator which control
the position of the bowl. In case of a defective switch,
mark the position of the switch and replace with a new
one in the same place, pay attention to connection and
wiring fig. 3.
Follow the instructions below to ensure the correct
position of the switch.
Fine adjustment actuator switches
• Check that the location of the contacts corresponds to
the dimensions in fig. 3
• Connect the contacts with the corresponding cables
• Adjustment of the three contacts must take place in
the following order:
1
Adjustment of upper contact (Top position of the
bowl)
• The switch must be positioned in accordance with the
target fig. 5
• The bowl is moved upwards to a location that
matches with the target X, fig. 5
• The upper switch is adjusted upwards until the LED
on the switch lights up
2
Adjustment of lift switch
• See opposite page fig. 4.
3 Adjusting the actuator switch for the JOG movement
• This switch B, fig. 3, is decisive for when the
machine’s JOG movement starts, see also the section
“Bowl lift and JOG function”, page 4
• The switch must be positioned in accordance with fig.
3
and does not need further adjustment
4
Adjustment of lower actuator switch
• This contact C, fig. 3, determines the bottom position
of the bowl
• The switch must be positioned in accordance with the
measurement in fig. 3
• The bowl is moved downwards to a position that
corresponds to the measure Y, fig. 5
• The lower actuator switch is adjusted downwards until
