This operation manual should thoroughly and completely be studied and
considered prior to initial start-up of the unit. When strictly following the
instructions, no danger should occur.
This machine must only be operated by qualified personnel who are fully
familiar with the operation and possible dangers. The operating instructions

“Working with liquid blasters” (BGV D 15) strictly to be followed.
The machine is not suitable for unattended operation. Protective clothing to be
worn.
The water stream emerging from the spray pistol at high speed has a rather
dangerous cutting effect. So, never direct the water stream onto persons or
animals, nor direct it onto electric units. When starting the machine, be aware
of torque and recoil. Take care of stable foothold.

proper ventilation and exhaust evacuation is not guaranteed. Exhaust gas is

Unsuitable or defective high pressure hoses very often cause accidents during
operation of high pressure cleaners. Therefore, check the hoses for damages
before any start-up. Defective hoses immediately to be replaced by original
OERTZEN equipment. Using other materials than original OERTZEN equip-
ment (union respectively hose marked with “OERTZEN”) or using materials
which have not expressively been approved by OERTZEN in writing voids all
warranties and product liability.
Worn out and/or defective high pressure hoses must never be repaired and
reused, but replaced immediately.
Spray pistols with delayed closing mechanism must not be used, due to risk of
injuries.
Lever in open position must not be blocked or fixed in any other way.
