• It is possible to cut over the water level adjustment bladder if the cutting heads are positioned as
such. Severe damage to the machine will occur if the bladder is cut by the high-energy waterjet.
Before you run a part program, make sure the cutting head will not cut through the bladder.
Abrasive
Garnet is the most frequently used abrasive. It is generally considered inert and has no known
health hazards. NEVER use silica sand as an abrasive—the dust produced causes silicosis, a
lung disease.
Never disconnect abrasive feed lines while under pressure. This can cause abrasive to spray into
eyes.
Noise emission
During the normal cutting operation—with the bottom of the material to be cut under water—the
distance of the nozzle exit to the material smaller than 2.5 mm – the noise emission is under 85
dB(A).
However, under certain circumstances, the machine causes higher noise emissions. At the start
of material drilling or cutting above the water, the noise level can climb over 115 dB(A). Always
wear hearing protection. The longer the jet, the higher the noise level.
Under certain circumstances, the area surrounding the machine can amplify sound effects, which
must be noted.
If the surrounding area becomes noisy, the sound from the adjacent areas must be monitored
and the necessary measures taken.
For the CF900 hopper
Sound levels were measured 1 m (3 ft) from the front of the ADS and 1.6 m (5 ft) from the
ground, during the following actions:
Conveying abrasive…………………………69.6 dBa
Pressurization…………………………79.4 dBa
De-pressurization…………………………98 dBa
