Maintenance - Weller Kahnetics KDS808 Manuel D'utilisation

6. Plug the 3-pin foot switch into the rear of the unit ( 6 ).
7. Insert the cartridge adapter in the air outlet ( 4 ) on the front of the unit and lock with a
clockwise 1/4 turn.
8. Turn on the unit ( 3 ).
9. Set the air pressure regulator ( 5 ) to the desired operating pressure.
10. Operate the foot switch to initiate material flow. Release the foot switch to stop the flow
of material.

1. Fit the quick-release coupling for the compressed air hose OD 6mm to the rear of the
unit ( 10 ) / ( 13 )* (12 mm spanner).
2. Connect filtered compressed air supply max. 7 bar with air hose OD 6mm ( 10 ) / ( 13 )*.
Important: Check the compressed air system for damage and ensure that the
compressed air hoses and couplings are seated properly. Protect the quick-release
coupling for the air supply against twisting.
3. Ensure that the unit is turned off.
4. Set the slide switch ( 12 ) / ( 15 )* to the correct mains supply voltage.
5. Connect up the mains lead ( 13 ) / ( 16 )*.
6. Plug the 3-pin foot switch into the rear of the unit ( 9 ) / ( 12 )*.
7. Insert the cartridge adapter in the air outlet ( 5 ) / ( 10 )* on the front of the unit and lock
with a clockwise 1/4 turn.
8. Set the timer control switch ( 6 ) / ( 8 )* to
"TIMED" for automatic timer control, or
"MANUAL" for manual timer control.
9. For automatic timer control the length of the dispensing pulse can be set on the 4-digit

decimal push-buttons ( 2 ) / ( 3 )*. Range of adjustment 0.01 – 99.99 sec. Set the air
pressure regulator ( 4 ) / ( 1 )* to the desired operating pressure.
10. Turn on the unit ( 7 ) / ( 11 )*.
11. Operate the foot switch.
With automatic timer control the foot switch can be released again immediately. The material
flow time is controlled automatically by the TIMER.
With manual timer control the material flows for as long as the operator depresses the foot
switch. This mode is recommended when varying quantities of material have to be dispensed
in succession.
The length of the dispensing pulse is indicated by a green LED ( 8 ) / ( 4 )*.
Using the vacuum function
The KDS808/834A/824A* dispensing systems incorporate a vacuum system. This vacuum is
present at the cartridge during the intervals between dispensing and prevents uncontrolled
dripping by low viscosity materials after the dispensing pulse.
The vacuum has infinitely variable adjustment, and is increased by turning the vacuum knob
( 2 ) / ( 1 ) / ( 5 )* in the direction of the arrow or counterclockwise. The vacuum should be as
low as possible depending on the viscosity of the medium.
Important: Foreign bodies must not enter through the vacuum system as this will clog
or damage it.
Compressed air port for accessories (KDS824A only)
The KDS824A dispensing system features a separate compressed air duct. The outlet pressure
can be adjusted from 0 - 7 bar with the right-hand pressure regulator ( 7 ). The set compressed
air is permanently present at the outlet ( 9 ) and has no control function.

3. Maintenance

The dispenser has been designed and constructed as a precision tool and will provide
maintenance-free operation under normal conditions. The unit should be kept free from dirt
