4.2 Change between 230V~ und 400V ~3P
If you change the operation mode of the disc saw TS40 between 230V~ und 400V~3P the frequency
converter FU6 D/C has to be disconnected for approx. 2 minutes in order to discharge the
intermediate circuit and re-initialize the controller.
4.3 Water connection
Connect the frequency converter 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 FU6 D/C with the disc 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.
If water exits of the leakage hole at the gear, the water seals have to be exchanged
immediately. This shoud only be done in an authorized repair station. Attention: Under
full load there are at least 1 l of water per minute required. 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 Dry cutting and semi-dry cutting
If you intend to cut dry, the motor still has to be cooled sufficiently with water. On top of the gear a
valve [12] is arranged. Turn the grip in the opposite direction of the blade guard and connect a hose
(8 mm outer diameter) to the angle screwing [13] via which the water can flow out. If the valve is
opened partially you are able to cut semi-dry. You just use the amount of water in order to bind the
dust.
4.5 Diamond saw blade (Cutting tool)
The saw blade diameter should be 400 mm. Smaller saw blades can be used also, but due to the
fixed circumferential speed these are not so efficient. Bigger diameters must not be used. The hole of
the saw blade has to be 25,4 mm (1"). The strength of the saw blade core shall be in the range of 1,5
- 2,5 mm.
Use only appropriate and well cutting high quality diamond tools. Take care that the diamond
segments overlap sufficiently over the blade body.
4.6 Change the saw blade
In order to remove or change the saw blade, remove the blade guard cover [8] with the face spanner.
Actuate the spindle lock [6] and loosen the hexagon screw [9] at the blade flange [10] simultaneously
with the wrench SW 17. Caution, the screw is provided with left-hand thread. Remove the blade
flange and the hexagon screw. Remove the saw blade. Grease the bore of the saw blade and the
flange hub [11], as well as the thread of the hexagon screw after having cleaned this area. Insert the
new saw blade in the blade guard and put it on the flange hub of the spindle. Please proceed in
reverse order and put the blade flange on the spindle. Take care that blade flange and spindle are
connected positively and tighten the hexagon screw counter-clockwise by actuating the spindle lock
simultaneously. Arrest the blade guard cover on the blade guard with the face spinner.
4.7 Change the position of the adjustable handle
In order to change the position of the adjustable handle [3] open the cam lever [7] in a horizontal
position. Adjust the handle in the requested position. Take care that the handle is catched in the
requested position and close the cam lever in a vertical position.
4.8 Change the position of the blade guard
Release the clamping lever [5] at the gear box and change the position of the blade guard in the
requested position. After the required position has been set tighten the clamping lever firmly.
Never work without blade guard.
Handle the blades with care. If single segments are missing or the blade is bad stressed, afflicted
with a fault in concentricity or wobble, dangerous unbalances can arise that can lead to damages on
the saw or can endanger the operator.
