Safety Instructions       

 

            

The following instructions to be followed before, during and after work: 
 

This instruction manual to be read completely before initial start-up. If strictly followed, 
no danger should occur. 

 

This machine must only be run by qualified adult persons who are fully aware of 
possible danger. Directives ZH 1/406 and BGR 500, as well as relevant national 
safety rules to be followed. 

 

The machine is not suitable for unattended operation and must be operated according 
to specification and intended purpose. Protective clothing to be worn. 
 
The water jet emerging from the spray pistol has a dangerous cutting effect. There-
fore the water jet must never be directed onto persons, animals or electrical installa-
tions. It must never be used for cleaning of clothes, footwear and the like. Be aware of 
torque and recoil. Ensure stable foothold.

 

 

The max. allowed pressure which is stated on the type plate must not be exceeded. 
The safety/control valve opens, if the max. operating pressure is exceeded by more 
than 20 bar and returns the water back into the suction side of the high pressure 
pump. The safety/control valve is workshop-set and sealed. Adjustment must not be 
changed. 
 
Machines driven by combustion engines must not be run indoors unless proper 
ventilation and exhaust gas evacuation are guaranteed. Exhaust gas is harmful, 
excessive concentration of carbon monoxide is lethal. 
 

 

Unsuitable respectively defective high pressure hoses often cause severe accidents 
during operation. Therefore high pressure hoses to be carefully inspected before 
start-up and replaced by original OERTZEN equipment in case of damage. Use of 
other than original OERTZEN equipment (hand nut marked with OERTZEN), results 
in expiry of the EC Declaration of Conformity, as well as product liability and warranty. 
 
Used or damaged high pressure hoses must never be repaired and reused but to be 
replaced by original OERTZEN equipment. 

 

Spray pistols with delayed closing mechanism must not be used because of risk of 
injuries. 
 
Lever in open position must never be blocked or fixed in any way. 
 
Use of spray wands of a length below 750 mm is prohibited. 
 
The machine must not be run in areas jeopardized by fire or explosions. During 
operation at filling stations “Technical Rules for flammable Liquids” (TfbF) to be 
observed. 
 
Consumables to be handled thoroughly according to technical rules and safety and 
environmental regulations to be observed.
