WARNING: Grip cleaning wand 
securely with both hands before 
starting. Failure to do this could 
result in injury from a whipping 
wand.

AVERTISSEMENT: Agripper la 
lance de nettoyage avec les deux 
mains avant de commencer. Le 
non-respect de cette consigne 
pourrait mener à des blessures 

causées par le mouvement violent de la lance.

WARNING: High pressure 
developed by these machines will 
cause personal injury or 
equipment damage. Keep clear of 
nozzle. Use caution when oper-
ating. Do not direct discharge 
stream at people or animals or 
severe injury or death will result. 

AVERTISSEMENT: La haute 

pression générée par la laveuse à pression 
raccordée au NG-3000 causera des lésions 
corporelles ou des dommages à l'équipement. Se 
tenir à l'écart de la buse. Faire preuve de prudence 
lors de l'utilisation. Ne pas décharger directement 
le jet vers des personnes ou des animaux, car cela 
risquerait de causer des blessures graves ou 
même la mort.

10. To reduce the risk of injury, close supervision is 

necessary when a machine is used near children. 
Do not allow children to operate the pressure 
washer. 

This machine must be attended during 

operation.

tion and knowledge of the machine.

have adequate slopes and 
drainage to reduce the possibility 
of a fall due to slippery surfaces.

AVERTISSEMENT: Faire preuve 
d'une extrême prudence au 

moment d'utiliser une échelle, des échafaudages 
ou toute autre surface relativement instable. La 
zone de nettoyage doit avoir une pente et un 
drainage adéquats pour réduire la possibilité d'une 
chute due à une surface glissante.
