Equipment Inspection - bar 120 BAR4023CG-HEC 2 Operator's Manual

To determine correct nozzle size for your HPWC you will need to know maximum pressure (psi) and flow (L/min).
Consult the nozzle sizing guide on our website bargroup.com.au.
If you required assistance in selecting an appropriate nozzle for your application visit the nearest authorised dealer or

Equipment inspection

Pressure cleaning equipment should be inspected regularly to ensure safe compliance and to avoid damage or
personal injury.
a) Keeping records of all equipment showing maintenance carried out and the results of formal inspections and
tests will prove such activities are carried out.
b) While inspection before/during/after use is important, it does not remove the need for regular formal
inspections to be carried out by the operator and/or company service team.
c) In the event of any equipment failure, a formal inspection of all equipment should be performed to identify
whether other components were damaged as a result of the failure. An incident report should also be
completed - See Page 11.
Nozzles are designed and sized specifically to control flow rate, pressure, direction and shape of jet. Using a nozzle
with a blocked or worn orifice, damaged threads, cracks or any other structural damage could result in significant
personal injury. As well as pre and post operation, performing inspections regularly during jetting operations can
identify worn or damaged nozzles before injury occurs.
Damaged nozzles should be immediately removed from service and then repaired or destroyed.
High pressure guns and triggers should be free from all leaks and when released should quickly cut off the flow of
water. If your trigger mechanism is not working correctly, remove from service immediately and take it to your nearest
dealer for repair or replacement.
Hose wear occurs over time but is significantly increased by many factors including:

environmental exposure to sharp edges or abrasive surfaces;

chemicals used in cleaning operations;

longitudinal stress from extended 'long-line' runs or long vertical drops;

exposure to temperatures above hose rating;

unnecessarily frequent pressure cycles or prolonged time at high pressures.
Where possible avoid the above to maximise the service life or your hose. In the case of chemical use, ensure
equipment is properly neutralised after use.
Any hose that has visible stress points, deep abrasions, bulges, kinks, leaks, corrosion, blisters or bubbles in the outer
covering should be considered defective.
Defective hoses should be immediately removed from service and clearly marked/tagged to prevent unintentional use.
Any other devices/equipment used with your pressure cleaner should be inspected regularly in accordance with the
manufactures documentation.
