Section 5: Operation
5.0 OPERATING ROTOMAG X22
As per the WJTA-IMCA Industry Best Practices, all operators shall fol-
low the OSHA regulations for personal protective equipment. (OSHA
guidelines for Personal Protective Equipment are available in document
number 3151-12R 2004, which can be obtained from www.osha.gov.)
All operators shall be issued suitable head protection, eye protection,
hearing protection, body protection, hand and foot protection and respira-
tory protection (if needed). For detailed specifications on all protections
required, refer to the WJTA-IMCA ‘Industry Best Practices for the Use of
High Pressure Waterjetting Equipment’ Section 6, Protective Equipment
For Personnel.
A centralizing device is strongly recommended when using
nozzle extensions to prevent damage to the extensions or the Rotomag
X22.
The Rotomag X22 can be used for minimum service tem-
perature of -20°C (-4°F) and a maximum service temperature of 115°C
(240°F). Use of lower or higher than recommended temperatures will
result in o-ring seal failure.
5.1 Start by slowly increasing pressure to 500 psi and check entire
system including all connections for leaks. Increase pressure in incre-
ments, pausing at each to inspect system for leaks, proper rotation of
tool, temperature, and other operational anomalies. If any problems are
discovered, lower pressure back to zero and turn off source of power
before making any adjustments.
5.2 During operation, it is normal for water to leak out the front of the
rotor from around the tow ring and between the rotor and body. This
leak-by water comes from the water bearing that the tool operates on.
