The optimum cutting speed (circumferential speed) of the saw blades depends on various factors
such as: the quality of the concrete, the aggregates and the proportion of reinforcing steel.
Observe the speeds and cutting depths recommended in the user manual and on the rating plate.
When sawing hard concrete reduce the circumferential speed or rpm.
The rate of advance can be increased with abrasive concrete.
Reduce the rate of advance if cutting concrete with a large proportion of reinforcing steel.
In case of critical or hazardous situations press the
EMERGENCY STOP button immediately.
8.5 Practical tips
Observe the saw blade's direction of motion!
8.5.1 Guide cut
The first cut is the guide cut.
Depending on whether the background is hard, soft or masonry, the feed depth should be
between 2 and 15 cm.
Saw blade diameter 700 mm / 28“; saw blade width: 4,4 mm / 0.17“
Do not make the first cut at maximum advance rate; this could cause an untrue cut.
Steel wedges must be used to secure a cut block.
8.5.2 Additional cuts
Here, too, the feed depth depends largely on the material and is between 5 - 10 cm / 2 - 4“.
Saw blade diameter 800 - 1000 mm / 32 - 40“; saw blade segment width: 4,1 mm / 0.16“
Always work using the progressive cutting method! A higher advance rate is better than too much
feed depth which causes dulling of the segments.
Always cut with the swivel arm pulling.
