stop” iis used before the mixer is restarted. Set the timer on HOLD when not used, as oth-
erwise the mixer can not be started.
The mixer must only bestarted when the bowl is in working position and the safety guard
is closed.
F Turn the speed selector lever (fig.4) to the rear until the required speed has been ob-
tained.
The speed must be changed only when the mixer is running.
The mixer must not be started when loaded in high speed position.

4.1.2 Procedure for starting after emergency stop
This procedure must be used in cases where the mixer has been stopped in high speed.
• Lower the bowl and remove the tool from the bayonet.
• Raise the bowl arms,either empty or with the bowl.
• Close the safety guard, start the mixer and move the speed selector lever back to
the lowest speed.
• Switch off the mixer. Now the mixer can be started as usual.
4.1.3 Overload
Do not overload the mixer. Sticky and heavy doughs may reduce the capacity of the bowl
by 75%. The capacity is further reduced if the speed of the mixing tool is increased be-
yond the recommended values or if a wrong mixing tool is used. Large lamps of fat or
cooled ingredients must be cut into small parts before they are placed in the bowl.
Prolong overload will make the mixer’s motor protection disconnect the mixer. Leave the
mixer for approx. 3 minutes and restart it again as described under “Procedure for starting
after emergency stop”.

4.1.5 Correct use of tools
The meat mincer must not be used for production of bread crumbs as this will cause un-
necessary wear and tear on some mixer parts.
Whips should not be struck against hard objects as e.g. the edge of the bowl. This will
make the life of the tool shorter due to increasing deformity.
4.1.6 Recommended applications for tools
Whip
•cream
• egg whites
• mayonnaise
• and the like
Beater
• cake dough
• butter cream
• waffle dough
• minced meat
• and the like
Hook
• bread dough
• dark bread
• and the like
For production of mashed potatoes the special wing whip should be used, not the standard
whip.
4.2 After use
4.2.1 Cleaning
The mixer should be cleaned daily or after use. The mixer should be cleaned with a soft
cloth and clean water. Sulphonated soaps should be used with caution as they destroy the
mixer’s lubricants.
Never use high pressure cleaning for the mixer.
Bowls and tools of aluminium must not be washed with strong alkaline detergents (pH not
bigger than 9.0).

Please note that the plastic safety guard can be damaged if exposed to high temperature
for a considerable period (Max. temperature 65°C).
After using the attachment drive, it should be wiped inside with a soft cloth.
4.2.2 Maintenance and lubrication
The infinitely variable gear must be lubricated regularly, i.e. a lubrication interval of ap-
prox. 60 hours of operation.
Lubrication of infinitely variable gear:
Use the grease gun delivered with the mixer.
Start the mixer and increase the speed to approx. 50%. Stop the mixer and open the lid on
the top of the mixer.On the top of each of the two pulley setshafts is a grease nipple (fig.5
point 1). Press grease through the grease nipples until the grease gun feels hard to press
or until grease comes out between the shaft and the pulleys.
The mixer must not be started until the screws which hold the lid are inserted.
Start the mixer and set the speed back to low speed.
Stop the mixer and fill the grease gun with new grease so that it is ready for next time.

Lubrication of other movable parts:
The movable parts of the bowl arms, the shaft and the lifting rod must also be lubricated
with oil. Remove the rear covering and lubricate the marked points with an oil can (fig.5
point 2).
Grease types:
Grease for the pulley set shafts: Castrol LMX
On repair of the planetary head: Grease thetoothed wheeland thetoothed rim with Castrol
Molub Alloy 936SF Heavy or Castrol Grippa 355, the needle bearings in the planetary
head must not be lubricated with this type of grease. Do not use any other type of grease
than the one stated here.

Installation

5. Installation
5.1 Preparing the installation
It should be checked that all loose parts are delivered with the mixer such as bowl, tools,
grease gun and rubber feet.
5.2 Installation
Never lift the mixer by the handle for speed adjustments or for bowl lift.
The mixer is placed directly on the floor. Foundation bolts in the floor are only necessary
under special conditions, e.g. on ships.
The mixer must be mounted with rubber feet, which neutralize both shaking and rusting.
Spacers can be inserted under the mixer’s feet, if the floor is not completely even.
5.3 Electrical connections
The electrical connections can only be carried out by a qualified electrician having the
necessary competence for the installation and service of electrical appliances.
The mixer is to be connected to power via a plug. The plug must be dimensioned for min.
16A, 230/400V~, IP44.
When connecting:
• 1 phase with 0+earth, use 3 pole plug
• 2 phases+earth, use 3 pole plug
• 3 phases+earth, use 4 pole plug
• 3 phases with 0+earth, use 5 pole plug
Before the mixer is connected to power, it should be checked that thevoltageand frequen-
cy printed on the machine label is correct in relation to the place of installation. The ma-
chine label is placed at the top right side of the mixer.
5.4 Checking of the direction of rotation of the planetary head
Lift up the bowl arms to normal working position and start the mixer without bowl and
tools. Check the direction of rotation ofthe planetary head: the planetary head must rotate
in the direction as stated by the arrow above the planetary head. If the direction of rotation
is wrong, 2 of the phase wires of the connecting cable must be inverted.

6. Adjustment instructions
Prior to a possible repair or adjustment, switch off the mixer by disconnecting the power
cable.
6.1 Adjustment of special V-belt
The distance (X) is only indicative as it depends on the tolerance of the special V-belt.
Start by tightening the V-belts (*)
Tighten the special V-belt (A) by moving one or two washers from (V) to (T).
Start the mixer and leave it running while the nut (U) is tightened. Do not tighten it too
much

Adjustment instructions
14
On the front pulley set the stud (E) on the varispeed collar (F) must be placed inside the
lower fork (G) and on the rear pulley set outside the fork for belt tightener (B), (both must
point backwards).
Tolerances in the transmission might cause that the special V-belt (A) is hitting the pins
of the pulley sets when the speed has been adjusted. In such cases the distance (X) must
be reduced.
Then follow the section ”Adjusment of speed”.
6.2 Adjustment of speed
The stop screws (J) on the speed lever should be adjusted so that the measurement (H) is
1-2 mm on the front and rear pulley, at low and high speed respectively. Tighten the coun-
ter nuts (K) when the speed is correctly adjusted.
6.3 Adjustment of bowl centering
First find the present bowl centering: mount the beater and the bowl, then raise the bowl
arms upto normal working position. With your hand turn the beater, and then measure the
distance between beater and bowl edge. By removing the rear covering the bowl arm
guide plate is now accessible (E). Loosen the screws (D) and move the bowl arm guide
plate in the required direction. Again turn the beater and measure the distance between
beater and bowl. When the bowl has been centered, fasten the bowl arm guide plate in the
new position and screw on the rear covering.
