Generally, the ribbed belt tension must be set
correctly when commissioning the power tool. At
initial commissioning, at recommissioning after
extended stand still, after replacement of the ribbed
belt or after any other assembly work, always
check the tension and set the correct tension if
required.
•
Loosen both attachment nuts (a).
•
Turn ribbed belt tensioning screw (13) towards
the right (clockwise).
è
Increase ribbed belt tension.
The square nut (b) moves to the mark "+".
•
Turn ribbed belt tension screw (13) towards the
left (counter-clockwise):
è
Reduce ribbed belt tension.
The square nut (b) moves to the mark "
−".
•
The correct tension is reached when the square
nut (b) is on the centre mark (c), in between "+"
and "−".
•
Tighten both attachment nuts (a) again.
Lots of fine dust occurs when cutting mineral
materials. We recommend using the water
connection when using cutting discs suitable for
wet cutting with mineral materials. When cutting
with the water supply connected, the dust is bound,
visual inspection is improved and the cutting disc
service life is increased by the cooling effect of the
water.
Before wet cutting:
•
Connect suitable water line or suitable pressure
tank to the coupling connection (24).
•
Operate the valve lever (28) to open or close the
water supply.
After wet cutting:
•
Close the water supply, i.e. put the valve lever
across the connection piece.
•
Let the cutting disc run at high speed for another
approx. 30 seconds to completely eject the
water.
Cleaning the screen filter insert in the coupling
piece (27):
