6.5 Use
m WARNING
• With gas or oil-fired machines it is important that sufficient
ventilation is provided and that the exhaust gases are
properly extracted.
m DANGER
• The operator must use the appliance properly. They must
take local conditions into account and pay attention to oth-
ers, especially children, when working with the appliance.
• This appliance may never be left unattended while it is in
operation.
• The appliance may only be used by people who have
been instructed in its use or whose ability to operate it
has been demonstrated and who are expressly tasked
with its use. This appliance may not be used by minors or
untrained persons.
• Always use suitable gloves when working on the appli-
ance.
• The water jet being ejected from the jet pipe creates a
recoil force. The angled jet pipe causes the force to be
exerted upwards. Hold the gun and the jet pipe firmly.
• Using angled spray equipment can help to reduce recoil
and twisting forces.
m WARNING
• The use of high-pressure cleaners can lead to the forma-
tion of aerosols. Inhalation of aerosols can be hazardous
to health. Grade FFP2 filter masks (or higher) are suitable
for protection from water-based aerosols.
6.6 Transport
m DANGER
• When transporting the device, the engine must be
stopped, the spark plug connector removed and the de-
vice securely fastened.
6.7 Maintenance
m DANGER
• Switch off the appliance before carrying out any cleaning
or maintenance work or when exchanging components.
• Before all work on the appliance and accessories, depres-
surise the high-pressure system.
• The spark plug connector must be removed.
• Corrective maintenance may only be carried out by ap-
proved customer service centres or specialists in this area
who are familiar with all the relevant safety regulations.
6.8 Accessories and spare parts
m DANGER
• To prevent hazards, repairs and the installation of replace-
ment parts may only be carried out by authorised custom-
er service centres.
• Use only spare parts that have been approved by the
manufacturer. Original spare parts and accessories offer
a better guarantee that the appliance can be operated
safely and reliably.
6.9 High-temperature water and petrol engine ap-
pliances
m DANGER
• Use only the fuel specified in the operating instructions.
The use of non-approved fuels increases the risk of explo-
sion.
• When refuelling petrol engine devices, take care not to get
any fuel on the hot surfaces.
• Always observe the special safety instructions for petrol
engine appliances contained in the operating instructions!
• When operating the appliance in interior rooms, sufficient
ventilation and exhaust gas extraction must be ensured
(risk of poisoning).
• The exhaust opening must not be blocked.
m WARNING
• Risk of burns! Do not bend over or touch the exhaust outlet.
6.10 Handling fuel
m DANGER
• Do not operate the high-pressure cleaner if fuel has been
spilt. Move the appliance to another location and avoid
all spark generation.
• Do not store, spill or use fuel in the vicinity of open flames
or appliances such as ovens, boilers, water heaters, etc.
that have a pilot flame or could generate sparks.
• Keep easily inflammable objects and substances away
from the exhaust silencer (at least 2 m).
• Do not operate the engine without the exhaust silencer
and check and clean this regularly (replace if necessary).
• Do not use the engine in wooded, bushy or grassy terrain
unless the exhaust pipe is fitted with a spark arrestor.
• Except during adjustment work, do not run the engine
without an attached air filter or without the cover over the
intake manifold.
• Do not make any adjustments to the regulator springs, control-
ler rods or other parts that could increase the engine speed.
• Risk of burns! Do not touch the hot exhaust silencer, cylin-
der or cooling fins.
• Keep your hands and feet away from all moving or rotat-
ing parts.
• Risk of poisoning! Do not operate the appliance in con-
fined spaces.
• Do not use any unsuitable fuels as these can be dangerous.
6.11 Safety devices
The safety devices are designed to protect the user and may
not be deactivated or repurposed.
6.11.1 Relief valve
• If the hand spray gun is closed, the relief valve opens and
the high-pressure pump routes the water back to the pump
suction side. This prevents the permissible working pressure
from being exceeded.
• The relief valve is set and sealed at the factory. It may only
be adjusted by the customer service.
6.11.2 Thermal valve
• The thermal valve protects the high-pressure pump from
impermissible warming in circulation operation if the hand
spray gun is closed.
• The thermal valve opens if the water temperature exceeds
55 - 60°C and drains the hot water.
