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 center 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.
