1 Safety
1.1 Important information
If the equipment is used improperly, the high-pressure jet from the nozzle can be dangerous
and result in serious injury and damage.
The water jet must never be aimed at people,
animals, active electrical equipment or at the high-pressure cleaner itself.
Before use, the high-pressure hoses, the high-pressure spray gun and the pump must all,
without fail, be inspected for possible damage. Hose lines must not be pinched, fed over sharp
edges, driven over by vehicles, tugged or bent. The rotary nozzle must not be operated if any
of the components mentioned above are damaged.
Any person engaged in operating, servicing, inspecting or assembling the equipment must be
appropriately qualified to carry out those tasks. The company operating the equipment must
produce precise instructions covering areas of responsibility, competence and how employees
are supervised.
Training and instruction must be given to any employees who do not have the necessary skills
and knowledge. If necessary, the manufacturer or supplier can provide this training on behalf
of the company operating the machine or pump. The company operating the equipment must
also ensure that their employees fully understand the contents of these operating instructions.
In addition to the safety instructions mentioned in these operating instructions, the
relevant statutory accident prevention and safety regulations must be observed and
adhered to!
1.2 Significant risks
Risk from the possible escape of liquid under high pressure
The water jet from high-pressure water jet equipment nozzles poses a risk due to its cutting
effect and its ability to penetrate objects, and because the high-pressure water jet nozzle and
hose may change direction or wander. Serious or even fatal injuries may be caused.
Hazardous substances may be released and it is also possible that parts of any object being
cleaned by the water jet may become loose.
Risk posed by handheld spray fixtures
Handheld spray fixtures pose a particular mechanical risk due to the recoil forces from the
water jet.
Risk posed by noise
Exposure to noise poses a risk. Exposure to noise can lead to loss of hearing, tinnitus or
physiological problems.
Noise can increase the risk of accidents because it may not be possible to hear alarms or
faults developing in the equipment.
Risk posed by vibrations
Pulsating vibrations from the pressure unit in handheld spray equipment poses a risk.
