Generally, the ribbed belt tension must be set
correctly when starting the power tool. At initial
starting, at re-starting 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).
Increase ribbed belt tension.
The square nut (b) moves to the mark "+".
Turn ribbed belt tension screw (13) towards the
left (counter-clockwise):
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.
Fine dust occurs when cutting mineral materials.
Recommendation: Use the water connection and
cut-off wheels suitable for wet cutting when cutting
mineral materials.
When cutting with the water supply connected, the
dust is suppressed, visibility is improved and the
cut-off wheel 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 cut-off wheel run at high speed for
another approx. 30 seconds to completely eject
the water.
