Water Connection - Weka TK40 ANNA Betriebsanleitung

Up to 100m length - 3G2,5 quality, e.g. H 07BQ-F or H 07RN-F
4.1.2 400 3 ~
Connect the TK40 via the frequency converter FU6 only on a properly earthed shockproof socket. If
required use only high quality extension cords with sufficient cross section.
Up to 100m length - 4G2,5 quality, e.g. H 07BQ-F or H 07RN-F
Take care that the extension cord is not rolled up on use for reaching a sufficient heat
removal. Consider that the TK40 takes the maximal power from the electrical mains.
Therefore do not connect other users to the concerning fuse, as the mains and the fuse
will then be overloaded. Please take care that the TK40 is only connected to an earthed
16A CEE socket. If you operate the machine at a higher assured socket, you risk in case
of any fault the total burning of the electronic. According to the relevant regulations
machines in the commercial sector may be operated only by means of a building power
distribution system. Ensure that a residual current circuit breaker of type B, or B + is
integrated, since an FI type A can fail in the event of a fault. By the high leakage current
the machine can electrify when touched, if the ground line is not connected correctly. In
this case absolutely disconnect the mains plug immediately and check the ground wire.
TK40 and FU6 can be used at a generator or a transformer provided by the construction site, if following
conditions are kept:
- operating voltage within +5% and –10 % to nominal voltage
- integrated automatic voltage controller with start amplification
- frequency 50 – 60Hz; max. 65 Hz
- AC voltage, power output at least:
230V ~
400V 3~
Do not use any other devices at the generator/transformator at the same time. The switching on and off
of other devices can cause undervoltage and / or over voltage peaks that can damage the machine.
4.2 Change between 230V~ und 400V ~3P
If you change the operation mode of the chain saw TK40 between 230V~ und 400V~3P the frequency
converter FU6U has to be disconnected for approx. 2 minutes in order to discharge the intermediate
circuit and re-initialize the controller.

Water connection

Connect the frequency converter FU6U via the plug-in nipple [23] to the water supply. The ball valve must
at any time be on the side of the water supply. Now connect the FU6U with the chain saw via a water
hose with a length of approx. 4,2 m (length of the cable).
Attention: water pressure max. 3 bar. Water may only be connected to ball valve, as
otherwise a damage on the casing may appear by upcoming water pressure.
Please use a GARDENA coupling as the connecting piece to the machine and the frequency converter.
This can be obtained from a garden center or builders' merchant made of plastics. A water coupling of
brass of high quality can be received directly from WEKA.
Use only clean water, as dirty water will considerably disturb the heat exchange on the cooling surface
and thereby the motor can be totally damaged.
Else the seals wear out very quickly.
In order to clean the rail and chain after completion of the work, the diamond chain saw
must be operated at idle speed with maximum water flow for at least 10-20 sec.
