INSPECTION & TESTING - BEFORE USE:

 

 

5.2.1 Routine Maintenance

:   

 

 

 

 

 

 

 

   

 

 

 

 

 

 

 

 

 

 

 

 

 

The Dustguard unit is designed to need minimal maintenance by the user. 

 

 

 

 

 

 

 

 

 

 

 

 

 

All repairs to this equipment must be carried out by qualified personnel. No modifications 
or changes to the specification of this  machine should be made without consultation and 
approval of the manufacturer.   

 

 

 

 

 

 

 

 

 

 

 

 

5.2.2  Hose Assemblies: 

 

 

 

 

 

 

 

 

 

Hose assemblies are of paramount importance with respect to water jetting equipment. 
Before using any hose assembly, it is essential to check the following points

.

   

 

No hose should be used where there is any evidence of external damage. Particular 
attention should be paid to exposed or broken wires which are not only likely to be a 
source of rupture but may also cause severe cuts.   

 

 

 

 

 

Of particular relevance are the end fittings of hoses, which can be subjected to stress 
caused by pulling at sharp angles or stretching.  Hoses must be inspected regularly. 

Where quick release couplings are employed they should be inspected regularly for wear, 
damage and for condition of any sealing rings.  

 

 

 

 

 

 

 

5.2.3 Guarding

:   

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The machine is provided with guarding in compliance with current legislation. The 
machine should not be operated with any of the guards, covers or any other safety 
equipment removed or damaged. 

 

5.2.4  Controls:   

 

 

 

 

 

 

 

 

 

 

 

Control functionality, principally the HP water shut off valve and oscillation controls should 
be checked. 

 

All throttle couplings and engine stop devices on the associated pressure washer shall be 
checked to ensure that they are functioning properly before high pressure jetting work 
commences.
