Water Connection - Weka TR40 ANNA Instrucciones De Servicio

Take care that the extension cord is not rolled up on use for reaching a sufficient heat
removal. Consider that the TR40 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 TR40 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.
TR40 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 ring saw TR40 between 230V~ und 400V~3P the frequency
converter FU6D/C 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 FU6D/C via the plug-in nipple [22] to the water supply. The ball
valve must at any time be on the side of the water supply. Now connect the FU6D/C 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.
Attention: Under full load there are at least 1 l of water per minute required. For cooling
and cleaning the rollers and saw blade during the operation of the ring saw, we
recommend a larger water flow - see section 3.1 Technical data. Open the ball valve
after use, so that the cooling gap can empty. This is mainly required in the cold season
- danger of frost.
4.4 Mounting stand
Screw the base [9] with the enclosed hexagon socket screws on the
reception of the ring saw.
Ensure that the splash guard (1) is installed away from the saw blade.
