OPERATION & MAINTENANCE 

General  
This equipment/machinery is designed and constructed for industrial use only for the suppression of 
dust and similar in controlled environments with limited access, for example fenced 
construction/demolition sites. 
It should only be used by persons trained and competent in its operation in accordance with the 
instructions within this manual, and should only be maintained / repaired by persons trained and 
competent to do so, following the isolation and making safe of the equipment as detailed within this 
manual. 
The machine must not be misused in any way, nor any hazardous areas accessed, for example 
inside the oscillating mechanism during operation. 
The machine should only be used in a safe location away from other persons not involved in the 
demolition activity and a safe working area should be established with other persons kept away. 
The machine should not be left unattended where there is the possibility of access or operation by 
unauthorised persons.  
 Safety in Operation 

  This equipment/machinery is designed and constructed for industrial use only for the 

suppression of dust and similar in controlled environments with limited access, for example 
fenced construction/demolition sites. 

  It should only be used by persons trained and competent in its operation in accordance with 

the instructions within this manual, and should only be maintained / repaired by persons 
trained and competent to do so, following the isolation and making safe of the equipment as 
detailed within this manual. 

  The machine must not be misused in any way, nor any hazardous areas accessed, for 

example inside the oscillating mechanism during operation. 

  The spray head must never be directed at any person or animal. 

  The machine should only be used in a safe location away from other persons not involved in 

the demolition activity and a safe working area should be established with other persons kept 
away, and monitored on a continuous basis. 

  The machine should not be left unattended where there is the possibility of access or 

operation by unauthorised persons. No guards or other safety features may be disabled or 
bypassed, nor may they be removed unless for authorised maintenance or repair, again 
following the correct isolation procedures. 

  The operator must not access, or allow access by others to any hazard area during operation, 

and all other persons must be kept away from these areas, notably: 

o

  From around the machine 

o

  From the area in which the spray is directed 

Safety features and regular checking 
Safety features are provided for the protection of all and their effectiveness must be verified and 
recorded on a daily basis as follows: 

  Oscillating mechanism enclosure/guard be in place, undamaged and effective. 

  Correct operation of oscillation Off/On selector and HP water isolation valve. 

  Safety signage in place and legible. 

Isolation for intervention, maintenance and repair 

  Before accessing any parts of the machine/equipment for purposes of maintenance or repair, 

make safe and isolate energy sources as follows (and in accordance with the user’s 
procedures): 

o

  Ensure the Commando unit is stopped and take precautions to prevent it from being 

started. 

o

  Ensure that the HP water is depressurised.
