WARNING
ADVERTÊNCIA
Fire and explosion hazard: Solvent and paint fumes can ignite or
explode.
To help prevent a fire and explosion:
Use only in an extremely well ventilated area.
Eliminate all ignition sources; such as pilot lights, cigarettes and
plastic drop cloths (static arc hazard). Do not plug or unplug power
cords or turn lights on or off in spray area.
Ground Sprayer, object being sprayed, paint and solvent pails.
Hold gun firmly to side of grounded pail when triggering into pail.
Use only conductive airless paint hose.
Do not use 1,1,1-trichloroethane, methylene chloride, other
halogenated hydrocarbon solvents or fluids containing such
solvents in pressurized aluminum equipment. Such use could
result in a chemical reaction, with the possibility of explosion.
To reduce risk of electric shock, use grounded outlet only. Shut
OFF and unplug when repairing.
Fluid injection and high pressure hazard: High pressure spray or
leaks can inject fluid into the body.
To help prevent injection, always:
Engage trigger safety latch when not spraying.
Keep clear of nozzle and leaks.
Never spray without a tip guard.
Do PRESSURE RELIEF if you stop spraying or begin servicing
sprayer.
Do not use components rated less than sprayer Maximum
Working Pressure.
Never allow children to use this unit.
If high pressure fluid pierces your skin, the injury might look like
“just a cut”. But it is a serious wound! Get immediate medical attention.
Perigo de incêndio e explosão: os solventes e os vapores da pintura
poderão explodir ou incendiar.
Para ajudar a evitar incêndio e explosão:
Utilize unicamente em áreas extremamente bem ventiladas.
Elimine todas as fontes de ignição, tais como luzes piloto, cigarros e
arcos de estática resultantes dos plásticos de proteção. Não ligue nem
desligue os cabos de alimentação ou as luzes numa área de
pulverização.
Ponha em contato com a terra o pulverizador, o objeto a ser
pulverizado, e os baldes de tinta e de solventes.
Segure a pistola firmemente de encontro ao lado do balde em contato com
a terra, quando estiver descarregando para dentro do mesmo.
Utilize somente tubos flexíveis condutores para pintura a alta pressão.
Não utilize 1,1,1-tricloroetano, cloreto de metileno, outros solventes de
hidrocarbonetos halogenados ou líquidos contendo tais solventes em
equipamento de alumínio pressurizado. Tal utilização poderá
resultar numa reação química, com possibilidade de explosão.
Para reduzir o risco de choque elétrico, use a tomada aterrada
somente. Feche FORA e desconecte ao reparar.
Perigo de injeção de líquidos à alta pressão: a pulverização ou vazamentos à alta pressão podem injetar líquido no corpo.
Para ajudar a evitar injeção de líquido, faça sempre o seguinte:
Engate o trinco de segurança do gatilho quando não estiver pulverizando.
Mantenha-se afastado dos bocais e locais onde há vazamentos.
Nunca pulverize sem que haja uma proteção na extremidade.
ALIVIE A PRESSÃO quando parar de pulverizar e antes de iniciar a
manutenção do pulverizador.
Não utilize componentes com uma classificação inferior à do pulverizador
Pressão Máxima de Trabalho.
Nunca permita que crianças utilizem esta unidade.
Se o líquido a alta pressão penetrar na sua pele, o ferimento poderá
parecer “simplesmente um corte”. Mas é um ferimento grave! Procure o
médico imediatamente.
MISE EN GARDE
Danger d’incendie et d’explosion : les gaz de solvant et de peinture
peuvent s’enflammer ou exploser.
Pour éviter les risques d’incendie et d’explosion :
N’utiliser l’appareil que dans une zone extrêmement bien aérée.
Éliminer toute source d’inflammation ; telle que veilleuses, cigarettes et
arcs d’électricité statique créés par les toiles de peintre en plastique. Ne
pas brancher et débrancher de cordons électriques, ou allumer et
éteindre des lumières dans la zone de pulvérisation.
Mettre à la terre le pulvérisateur, l’objet à pulvériser ainsi que les seaux
de peinture et de solvants.
Tenir le pistolet fermement contre la paroi d’un seau mis à la terre lorsqu’on
pulvérise dans le seau.
N’utiliser qu’un flexible pour peinture pulvérisée sans air.
Ne jamais utiliser de trichloroéthane 1,1,1, de chlorure de méthylène,
d’autres solvants à base d’hydrocarbures halogénés, ni de produits
contenant de tels solvants dans un équipement sous pression en aluminium. Cela pourrait provoquer une réaction chimique avec risque d’explosion.
Pour réduire le risque de décharge électrique, employez la sortie au
sol seulement. Coupez et débranchez quand la réparation.
Danger d’injection de fluide et haute pression : la pulvérisation sous
haute pression ou les fuites peuvent injecter des fluides dans le corps.
Pour éviter les risques d’injection, toujours :
Bloquer le loquet de sécurité de la gâchette à la fin de la pulvérisation.
Se tenir loin de la buse et des fuites.
Ne jamais pulvériser sans anti-gouttes.
DÉCHARGER LA PRESSION à la fin de la pulvérisation ou avant de
réparer le pulvérisateur.
Ne pas utiliser de composants dont la pression nominale est inférieure à
la pression maximale de service du système.
Ne jamais permettre aux enfants d’utiliser cet appareil.
Si un fluide haute pression perce la peau, la blessure peut paraître
une “simple coupure” Mais il s’agit bien d’une lésion grave! Consulter
immédiatement un médecin.
ADVERTENCIA
Peligro de incendio o explosión: Los gases de los disolventes y de la
pintura pueden inflamarse o provocar una explosión.
Para prevenir incendios y explosiones:
Use únicamente en un área muy bien ventilada.
Suprima todas las fuentes de ignición; como luces piloto, cigarrillos y
arcos estáticos de carpetas plásticas para protección contra pintura. No
enchufe ni desenchufe cables de alimentación ni apague ni encienda las
luces en un área de pulverización.
Ponga a tierra el pulverizador, el objeto que recibe el chorro pulverizado,
las cubetas de pintura y disolvente.
Sostenga firmemente la pistola a un lado de la cubeta puesta a tierra
cuando dispare dentro de ella.
Use solamente mangueras para pintura conductora sin aire.
No utilice nunca tricloretano-1,1,1, cloruro de metileno ni otros
disolventes a base de hidrocarburos halógenos o fluidos que contengan
dichos disolventes en un equipo a presión de aluminio. El uso de estas
sustancias puede provocar una intensa reacción química, con riesgos
de explosión.
Para reducir el riesgo de la descarga eléctrica, utilice el enchufe
puesto a tierra solamente. Apague y desenchufe al reparar.
Peligro de inyección de fluido y alta presión: por la pulverización o las
filtraciones a alta presión se pueden inyectar fluidos en el organismo.
Para prevenir la inyección en la piel, siempre:
Enganche el seguro del gatillo cuando no use el pulverizador.
No se acerque a la boquilla ni a las filtraciones.
Nunca aplique fluido pulverizado sin un guardaboquilla.
Realice el ALIVIO DE PRESIÓN si deja de pulverizar fluido o repara el
pulverizador.
No use componentes de capacidad nominal inferior a la presión máxima
de operación del pulverizador.
No permita que niños usen esta unidad.
Si fluido de alta presión le penetra la piel, la lesión podría parecer “sólo
un corte”. ¡Es una lesión seria! Consulte de inmediato al médico.

Maintenance
WARNING
INJECTION HAZARD
The system pressure must be manually
relieved to prevent the system from
starting or spraying accidentally. Fluid
under high pressure can be injected through the
skin and cause serious injury. To reduce the risk of
an injury from injection, splashing fluid, or moving
parts, follow the Pressure Relief Procedure
whenever you:
are instructed to relieve the pressure,
stop spraying,
check or service any of the system equipment,
or install or clean the spray tip.
Pressure Relief Procedure
DAILY: Check engine oil level and fill as necessary.
DAILY: Check hydraulic oil level and fill as neces-
sary.
DAILY: Check hose for wear and damage.
DAILY: Check gun safety for proper operation.
DAILY: Check pressure drain valve for proper opera-
tion.
DAILY: Check and fill the gas tank.
DAILY: Check that displacement pump is tight.
DAILY: Check level of TSL in displacement pump
packing nut. Fill nut, if necessary. Keep TSL in nut to
help prevent fluid buildup on piston rod and premature
wear of packings and pump corrosion.
1. Lock gun trigger safety.
2. Turn engine ON/OFF switch to OFF.
3. Move pump switch to OFF and turn pressure
control knob fully counterclockwise.
4. Unlock trigger safety. Hold metal part of gun firmly
to side of grounded metal pail, and trigger gun to
relieve pressure.
5. Lock gun trigger safety.
6. Open pressure drain valve. Leave valve open until
ready to spray again.
If you suspect that the spray tip or hose is completely
clogged, or that pressure has not been fully relieved
after following the steps above, VERY SLOWLY
loosen tip guard retaining nut or hose end coupling to
relieve pressure gradually, then loosen completely.
Now clear tip or hose.
CAUTION
For detailed engine maintenance and specifications,
refer to separate Honda Engines Owner’s Manual,
supplied.

Graco warrants all equipment listed in this manual which is manufactured by Graco and bearing its name to be free from defects in
material and workmanship on the date of sale by an authorized Graco distributor to the original purchaser for use. With the exception of
any special extended or limited warranty published by Graco, Graco will, for a period of twelve months from the date of sale, repair or
replace any part of the equipment determined by Graco to be defective. This warranty applies only when the equipment is installed,
operated and maintained in accordance with Graco’s written recommendations.
This warranty does not cover, and Graco shall not be liable for general wear and tear, or any malfunction, damage or wear caused by
faulty installation, misapplication, abrasion, corrosion, inadequate or improper maintenance, negligence, accident, tampering, or
substitution of non-Graco component parts. Nor shall Graco be liable for malfunction, damage or wear caused by the incompatibility of
Graco equipment with structures, accessories, equipment or materials not supplied by Graco, or the improper design, manufacture,
installation, operation or maintenance or structures, accessories, equipment or materials not supplied by Graco.
This warranty is conditioned upon the prepaid return of the equipment claimed to be defective to an authorized Graco distributor for
verification of the claimed defect. If the claimed defect is verified, Graco will repair or replace free of charge any defective parts. The
equipment will be returned to the original purchaser transportation prepaid. If inspection of the equipment does not disclose any defect
in material or workmanship, repairs will be made at a reasonable charge, which charges may include the costs of parts, labor, and
transportation.
Graco’s sole obligation and buyer’s sole remedy for any breach of warranty shall be as set forth above. The buyer agrees that no other
remedy (including, but not limited to, incidental or consequential damages for lost profits, lost sales, injury to person or property, or any
other incidental or consequential loss) shall be available. Any action for breach of warranty must be brought within two (2) years of the
date of sale.

in making any claim for breach of these warranties.
In no event will Graco be liable for indirect, incidental, special or consequential damages resulting from Graco supplying equipment
hereunder, or the furnishing, performance, or use of any products or other goods sold hereto, whether due to a breach of contract,
breach of warranty, the negligence of Graco, or otherwise.
