Operating Instruction
High Pressure Cleaner cold water, mobile
Series 3x3
Under the influence of the high pressure jet, parts can be separated from
the cleaning object and thrown away. Persons can be injured as a result.
Never aim the high pressure jet at fragile or loose objects.
When cleaning tyres and their valves, keep a minimum distance of 30 cm
from the high pressure nozzle. Otherwise damage may occur.
Before cleaning the High Pressure Cleaner cold water, mobile - Series 3x3
itself, take the device out of operation and disconnect it from the electrical
mains connection. Secure the device against unintentional or unauthorised
restarting (e.g. lock main switch, warning sign indicating work on the high
pressure cleaner, etc.).
Never operate the device unattended.
The device is designed for a water inlet temperature of up to 45 °C (device
version Standard and Premium) resp. up to 80 °C (device version Standard
and Premium for food appliance). When operated with hot water, watercarrying parts (for example pump housing, uninsulated pipes, metal parts
of the trigger gun and spray lance) as well as cleaning objects may become
hot. Touching hot surfaces can cause burns or scalding of the skin surface.
Make sure surfaces have cooled before touching. The hot water escaping
from the trigger gun must not come into contact with the skin.
2 Safety
Asbestos-containing and other materials containing substances hazardous
to health must not be sprayed off.
Information on hearing protection
If the sound levels exceed the permissible values, the personnel and
persons in the area of exposure must wear hearing protection.
The sound level for EHRLE high pressure cleaners under maximum load is
82 dB (A). A high sound level over a long period can cause hearing loss. If
the noise produced by the application of the emerging high pressure jet
to noise-enhancing objects exceeds the permissible values, the operating
personnel and any persons affected must wear hearing protection.
Do not operate the device if electrical cables or other safety-relevant parts
(pressure relief valve, HP-Hose, trigger gun, etc.) are defective.
2.4 Accident prevention regulations
Observe the applicable national regulations of the legislator on accident
prevention.
300781 • 1/2019 • H.S.
2.5 Lifting and moving loads
The High Pressure Cleaner cold water, mobile - Series 3x3 weighs from
48 to 60 kg depending on the type (with packaging from approx. 66 kg to
approx. 78 kg).
Lifting and moving loads is permitted for one person up to 23 kg. If the
load exceeds 23 kg use suitable lifting equipment (e.g. forklift, lift trucks).
Observe the international standard „ISO 11228-1 Ergonomie - Manuelles
Handhaben von Lasten - Teil 1 Heben und Tragen 05/2003“.

Operating Instruction
High Pressure Cleaner cold water, mobile
Series 3x3
2.6 Periodic inspections
The periodic inspections are listed in Section 8 (Maintenance).
2.7 Guidelines for liquid sprayers
High pressure cleaners must be inspected by an expert in accordance with
the „Guidelines for liquid sprayers“, if necessary or at least every
12 months. The result of the test must be recorded in writing.
In the appendix of this manual there is a test sheet (proof of customer
service) to record the tests carried out.
EHRLE service technicians are experts and can be consulted and
commissioned by EHRLE service for this prescribed inspection.
2.8 Design changes to the device
Design changes to the high pressure cleaner are not permitted.
When operating a device which has been modified or changed in design,
the device will not be used for its intended purpose. If the device is not
used for its intended purpose, no liability or warranty will be accepted (see
Section 1.7, Warranty and Liability).
2.9 Safety devices
Safety devices serve to protect the user and must not be suspended or
circumvented in their function.
The high pressure cleaner has the following safety devices listed below:
● Pressure switches:
Device functions are switched on or off (safety functions) based on type
of construction and intended use.
● Unloader valve and non-return valve:
The first serves to adjust the operating pressure and the second valve
keeps the pump head depressurised when the trigger gun is deactivated.
● TSS system with pump-off delay:
After deactivating the trigger gun, the pump continues operation for
approx. 30 s in the pressureless bypass mode (avoidance of too high
pressure build-up in the pump); after 30 s the high pressure cleaner
automatically switches into the stand-by mode.
● Total Switch-off:
Automatically switches the high pressure cleaner off in the event of
prolonged interruption of operation or unused trigger gun for more
than 20 minutes.
● Overload protection switch:
When the motor current load is too high the switch releases and the
device is switched off.
● Mechanical arrest for trigger gun:
Prevents unintentional or unconscious activating the trigger gun.
