or the selling dealer for specific details. If your 
machine is rated 250 volts or less, single phase a 
ground fault circuit interrupter (GFCI) will be 
provided. If rated more than 250 volts, or more 
than single phase this product should only be 
connected to a power supply protected by a GFCI.

DANGER: Improper connection of the equipment-
grounding conductor can result in a risk of electro-
cution. Check with a qualified electrician or service 
personnel if you are in doubt as to whether the 
outlet is properly grounded. Do not modify the plug 
provided with the product - if it will not fit the outlet, 
have a proper outlet installed by a qualified electri-
cian. Do not use any type of adapter with this 
product.

AVERTISSEMENT: Une mauvaise connexion du 
conducteur de terre de l'équipement peut entraîner 
un risque d'électrocution. Vérifier auprès d'un 
électricien qualifié ou du personnel d'entretien si 
vous avez des doutes quant à savoir si la sortie est 
correctement mise à la masse. NE PAS modifier la 
fiche fournie avec le produit - si elle n'entre pas 
dans la sortie, faire installer une sortie appropriée 
par un électricien qualifié. NE JAMAIS utiliser un 
adaptateur avec ce produit.

WARNING: Keep wand, hose, and 
water spray away from electric 
wiring or fatal electric shock may 
result.

AVERTISSEMENT: Garder la 
lance, le boyau et le jet d'eau à

pourraient survenir

5.

To protect the operator from electrical shock, the 
machine must be electrically grounded. It is the 
responsibility of the owner to connect this machine 
to a UL grounded receptacle of proper voltage and 
amperage ratings. Do not spray water on or near 
electrical components. Do not touch machine with 
wet hands or while standing in water. Always 
disconnect power before servicing.

WARNING: Flammable liquids can create fumes 
which can ignite, causing property damage or 
severe injury.

AVERTISSEMENT: Des liquides inflammables 
peuvent produire des vapeurs qui peuvent 
s'enflammer, causant ainsi des dommages à la 
propriété ou des blessures graves.

WARNING: Risk of explosion — Do 
not spray flammable liquids.

AVERTISSEMENT: Risque d'explo-
sion - Ne pas pulvériser de 
liquides inflammables.

6.

Do not allow acids, caustic or 
abrasive fluids to pass through 
the pump.

7.

Never run pump dry or leave 

spray gun closed longer than 1-2 minutes.

8.

Keep operating area clear of all persons.

WARNING: High pressure spray 
can cause paint chips or other 
particles to become airborne and 
fly at high speeds. To avoid 
personal injury, eye, hand and foot 
safety devices must be worn.

AVERTISSEMENT: Un jet haute 
pression peut écailler la peinture 
ou provoquer l'émission d'autres 
particules dans l'air et leur 

projection à hautes vitesses.

9.

Always wear properly rated eye protection such as 
safety goggles or face shield while spraying.
