No.
Fault
Cause
Remedy
1
Mixer does not work or works
with interruptions.
1.1.Lack of voltage in mains
socket.
Check to make sure there is voltage in the electricity supply network.
1.2.Power cord damaged or
damage to internal wiring.
Check the power cord and internal wiring. Rectify the fault or renew the
damaged cord.
1.3.Motor damaged.
Dismantle the mixer, dismantle the motor, repair and test the motor.
1.4.Speed selection switch
damaged.
Check the switch for operational quality.
In the case of damage replace it with the new one.
1.5.Capacitor damaged.
Replace with the new one.
2
Motor does not work or works
with interruptions.
2.1.Brushes worn out to large
extent or suspended in
brush-holder frames.
.
Unbend the brush-holder lugs and remove the brushes. In the case of
finding that they are worn out up to 5 mm, replace them with new ones.
In the case of brush suspension, clean the brush-holder from dust and,
where necessary, slightly rub the lateral edges of brushes with fine-
grained abrasive paper (no. 600 or 800).
2.2.Bad contact between
brush and commutator
due to dirt or shorting on
commutator.
Wipe the commutator with a cloth moistened in spirit. If the dirt cannot
be removed, rub the commutator with fine-grained abrasive paper (no.
600 or 800 ) and remove any possible shorting between the commutator
sections.
2.3.Shorting or break on rotor.
Dismantle the motor, Check the rotor. In the case of shorting or break in
the rotor Winding, replace with the new one. The winding resistance is
30.5
±0.5%, when measured between two opposite sections of the
commutator.
2.4.Break or shorting in stator
windings.
Dismantle the motor. In the case of finding the damage, replace the
windings with the new ones, after cleaning the package from coal and
impregnating resin dust. The stator winding resistance at the third gear
is 29±0.5%, at the forth gear 23±0.5%, at the fifth gear 17±0.5%.
3
Switch is blocked on particular
gears.
3.1.Elastic arm of switch lever
is damaged.
Dismantle the mixer, Replace the switch with the new one.
3.2. Metal ball is missing.
Dismantle the mixer. Insert the ball in the movable contact socket.
4
No difference between
speeds on particular gears.
4.1.Diode reducing voltage on
one of switch speeds is
damaged.
Dismantle the mixer. Replace the switch with the new one, possibly
renew the diode.
5
Mixer constantly works on
maximum speed.
5.1.”Turbo” switch pusher is
blocked.
Dismantle the mixer. Replace the switch with the new one.
5.2.Maximum speed switch
contacts are closed.
Dismantle the mixer. Open the switch contacts, possibly replace the
switch with the new one.
6
No possibility to switch „turbo”
speed on lower gears.
6.1.”Turbo” switch pusher is
blocked.
Dismantle the mixer. Check for switch pusher blocking. Remove the
cause of blocking.
6.2.Switch pusher is
deformed.
Dismantle the mixer. Replace the switch with the new one.
6.3.Large clearance between
switch contacts.
Dismantle the mixer. Bring the “turbo” contacts nearer.
7
No drive to dough hooks.
Motor is working.
7.1.Gear wheel teeth
damaged.
Dismantle the drive. Renew the gear wheels.
8
No drive to mixing
attachment. Motor is working.
8.1.Clutch on motor shaft is
damaged.
Dismantle the motor. Replace the clutch with the new one.
8.2.Mixing attachment clutch
damaged.
Replace the mixing attachment with the new one.
8.3.No coupling.
Incorrect The length of mixing attachment shaft is incorrect
– replace the
attachment with the new one.
The thread of the threaded end is damaged
– replace the threaded end
with the new one.
9
Difficulties when removing
attachments.
9.1.Pusher damaged.
Replace the pusher with the new one.
9.2.Gear wheel holes dirty or
dough hooks damaged.
Remove the dough hooks. Clean the gear wheel holes. Check the
pusher for proper operation. Replace the deformed dough hooks or
whisks with the new ones.
10
Housings damaged.
10.1.Overheating of motor or
mechanical damage.
Dismantle the mixer. Replace the housings with the new ones.
