High pressure water (from the spray)
•
The machine must be used in a controlled and managed environment by trained operators
only, ensuring that persons are not present in the spray zone.
•
Before use, the machine must be set up and started by a competent operator to ensure basic
safety criteria are met.
•
The machine should never be moved nor any adjustments made unless the Commando unit
is shut down and HP water valved off.
•
Persons must be made aware of and instructed to keep themselves and others away from
hazard areas, notably within 20m of the spray head.
•
The spray head should never be directed at any individual
•
The HP water system should be visually checked daily for any leaks which should be rectified
before continuing to use the equipment.
•
Appropriate face/eye protection should be worn when using the machine.
Starting up of the machine and spray should be carried out in the following sequence:
•
With the engine stopped, locate the machine in the required position on site.
•
Ensure the valve controlling the HP water to the spray unit is OFF; the oscillation is OFF; and
the oscillation stroke set to minimum.
•
Set the spray elevation and stroke to meet anticipated requirements.
•
Ensuring yourself and others are well clear of the spray zone, start the Commando unit.
•
Once up to pressure and ensuring the spray zone remains clear of people, gently open the
HP water valve and when fully open, check that the spray is going where required.
•
Any further adjustment of the spray elevation angle or stroke should only take place with the
HP water valve isolated/ Commando engine stopped.
Lifting and moving of unit

The Commando washer and spray unit may be fitted with larger wheels and/or a lifting frame
to facilitiate movement around site.

All such lifting/movement should only be carried out by trained and competent persons using
approved and tested equipment.

The lifting frame, if fitted, should be periodically inspected and tested as required under the
Lifting Operations and Lifting Equipment Regulations to ensure continuing integrity.
