REPAIR INSTRUCTION

- The spare parts have been standardized as much as possible.

- Cotton dustbags are used in countries where paper dustbags
are unobtainable.

- If the reel half spring unit is replaced, shaft F must be
lubricated with silicone grease. Do not apply any silicone
grease to or spill any grease on terminals (36) or conductors
(35).

- Item 34 is provided with a long cord-winder spring, but
both long and short cords can be used in combination with
this spring. (L = 9.3 m)

- Depending on the length of the original cord, the spare
cord may have to be shortened.

- The cord winder spring must be tensioned to the maximum
level and then be rewound approx. 1.5 turn.

- The RPM can be adjusted by means of the potentiometer
mounted on the PCB (item 25). The RPM is correctly
adjusted if the motor starts automatically and continues to
run smoothly with the ON/OFF position and the
adjustable potentiometer in minimum position.

- If the function of the electronic control unit (item 25) is
not required, the Triac must be short-circuited in the
manner shown in the circuit diagram.

- When the vacuum cleaner is used to suck up fine dust, the
pores of the dustbag may become clogged, causing the
passage of air through the dustbag to become obstructed.
As a result, the dustbag-full indicator will indicate that the
dustbag needs to be replaced, even though the dustbag is
not full at all.
