  Hazard levels 
 

 

    

DANGER - 

Indication of an immediate danger potentially resulting in serious injuries or death. 

 

 CAUTION - 

Indication of a potential hazardous situation that may result in light injuries. 

 

  

WARNING - 

Indication of a potential hazardous situation that may result in material damage. 

 
 

  Safety features

 

 

  

CAUTION - 

Safety features are designed to protect their users from injuries and these may not be altered in any 

way or even put out of order

Any damaged items must be replaced with original spare parts only. 

 
    Protective guards on hot or rotating parts 
 
The protective guards are designed for protection of operators using the high-pressure washer to avoid injuries caused 
by temperatures of certain components of the combustion engine or injuries caused by rotating parts of the device. 
 
  Safety features on the combustion engine and pump  
 
The engine oil level safety switch (if fitted) serves for automatic deactivation of the engine in case the engine oil level 
drops below the minimum threshold. That will prevent damage to the engine due to insufficient lubrication of internal 
parts. However, this safety features does not substitute the need to check the engine oil level prior to use of the device.  
For further important information see the section – ENGINE (p. 4). 
 
The pump safety valve serves for drainage of some hot water developed during internal circulation of water inside the 
pump during operation without discharge of the high-pressure water.  
Once the safety valve opens automatically, some of the hot water pours out of the pump to be replaced with cold water 
from the connected supply. However, this safety feature does not substitute the need to switch the pump off when not in 
use for periods exceeds 2 minutes. For further important information see the section – PUMP (p. 7). 

 

  

Scope of delivery

 

 

For depiction of delivery contents see the packaging or the purchase order. Check the contents completeness 
when unpacking. Any items missing or any damages incurred in transport should be notified to the seller. 
 

  Additional items required 
 
 

Fabric-reinforced water hose with the diameter of ½“ (13 mm) with a regular garden quick-coupler. 
The supply hose must be at least 5 m and at most 15 m long. The device must be linked to an adequate water 
resource with the minimum delivery pressure of 1 bar and the flow rate of 12 l/hr. 
 
 

  

Assembly

 

 
The device itself is assembled in the manufacturing plant. Fix the upper frame section - grip - onto the bottom 
part, by sliding it onto the narrowed part of the tube and use the flexible metal spring to lock it in place. (Figure 
on page 3). Before connecting the hoses, remove the covers from the high-pressure water outlet and inlet on 
the pump. The first operation requires connection of the high-pressure hose, included in the delivery, with the 
control gun and nozzle to the high-pressure section of the pump.  
The next step requires filling of the supplied oil into the engine, as directed by instructions in the section 

ENGINE

 (p. 4) and filling the tank with fresh petrol with octane rating of 95.
