WARNING
Fire and explosion can occur when spraying or flushing flammable
fluid in an area where air circulation is poor and flammable vapors
can be ignited by an open flame or sparks.
To help prevent a fire and explosion:
Use outdoors or in an extremely well ventilated area.
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.
Remove, extinguish or unplug all ignition sources;
tape wall switches. Do not smoke in spray area.
Never fill fuel tank while the engine is running or hot.
Ground Sprayer, object being sprayed, paint and solvent pails.
Hold gun firmly to side of a grounded pail when triggering into pail.
Use only conductive airless paint hose.
Never run engine in inclosed area.
ADVERTÊNCIA
Poderá ocorrer incêndio e explosão quando for pulverizado ou injetado
líquido inflamável numa área onde houver má circulação de ar; vapores
inflamáveis poderão incendiar-se a partir de uma chama ou fagulhas a
descoberto.
Para ajudar a evitar incêndio e explosão:
Utilize no exterior ou numa área muito bem ventilada.
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.
Retire, elimine ou desligue todas as fontes de ignição; coloque fita
adesiva na tomada da parede. Não fume na área de pulverização.
Nunca abasteça o depósito de combustível com o motor em funciona-
mento ou quente.
Ponha em contato com a terra o pulverizador, o objeto a ser pulveriza-
do, e os baldes de tinta e de solventes.
Segure a pistola firmemente de encontro ao lado de um balde em contato
com a terra, quando estiver descarregando para dentro do mesmo.
Utilize somente tubos flexíveis condutores para pintura a alta pressão.
Nunca faça funcionar o motor numa área fechada.
Fluid injection is a serious injury! 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.
To help prevent injection, always:
Engage trigger safety latch when not spraying.
Point gun away from yourself or anyone else.
Relieve pressure before checking or repairing any leak.
Relieve pressure when you turn off the sprayer or stop spraying.
Do not use components rated less than system
Working Pressu re
Never allow children to use this unit. If you are injured using this
equipment, get immediate medical treatment.

MISE EN GARDE
Risque d’incendie et d’explosion imminent pendant la pulvérisation
ou le rinçage à pression de fluides inflammables dans une zone à mauvaise circulation d’air et en présence de gaz inflammables pouvant
s’allumer par une flamme nue ou des étincelles.
Pour éviter les risques d’incendie et d’explosion:
Manipuler les fluides à l’air libre ou dans une zone extrêmement
bien aérée.
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.
Retirer, éteindre ou déboucher toute source d’inflammation, recouvrir
tout interrupteur mural avec du ruban adhésif. Ne pas fumer dans la
zone de pulvérisation.
Ne jamais remplir le réservoir d’essence lorsque le moteur est chaud
ou en marche.
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 mettre en marche un moteur dans une zone fermée.
A injeção de líquido é um ferimento grave! 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.
Para ajudar a evitar injeção de líquido, faça sempre o seguinte:
Engate o trinco de segurança do gatilho quando não estiver pulveri-
zando.
Sempre aponte a pistola para longe de você mesmo(a) ou de outras
pessoas.
Alivie a pressão antes de verificar ou reparar qualquer vazamento.
Alivie a pressão quando desligar o pulverizador ou parar de pulverizar.
Não utilize componentes classificados para uma pressão nominal
inferior à pressão máxima de trabalho dos sistemas.
Nunca permita que crianças utilizem esta unidade. Se sofrer algum
ferimento durante a utilização deste equipamento, procure o médico
imediatamente.
ADVERTENCIA
Pueden ocurrir incendios y explosiones cuando se pulveriza fluido inflamable o cuando se lava con este tipo de fluido en un área donde la
circulación de aire es deficiente y los vapores inflamables se pueden encender al contacto con el fuego o chispas.
Para prevenir incendios y explosiones:
Use en espacios abiertos o en un área muy bien ventilada.
No utilice nunca tricloretano–1,1,1, cloruro de metileno, u otros di-
solventes a base de hidrocarburos halógenos o fluidos que contengan
tales disolventes en un equipo a presión de aluminio. El uso de estas
sustancias puede provocar una intensa reacción química, con riesgos
de explosión.
Retire, apague o desconecte todas las fuentes de ignición; asegure el
interruptor de la pared con cinta. No fume en el área de pulverización.
Nunca llene el estanque de combustible mientras el motor esté en
marcha o caliente.
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.
Nunca haga andar el motor dentro de un área cerrada.
L’injection de fluide constitue une lésion grave! Si un fluide haute
pression perce la peau, la blessure peut paraître comme une
«simple coupure». Mais i l s’agit bien d’une lés i on grave! Consul t er
immédiatement un médecin.
Pour éviter les risques d’injection, toujours:
Bloquer le loquet de sécurité de la gâchette à la fin de la pulvérisation.
Pointer le pistolet loin de soi-même et toute autre personne à proximité
Décharger la pression avant de vérifier ou réparer une fuite.
Décharger la pression après la mise hors tension du pulvérisateur ou
à la fin de la pulvérisation.
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. En cas de blessure pour avoir utilisé cet appareil, consulter immédiatement un médecin.
¡La inyección de fluido en la piel es una lesión seria! 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.
Para prevenir la inyección en la piel, siempre:
Enganche el seguro del gatillo cuando no use el pulverizador.
No apunte la pistola ni a sí mismo ni a los demás.
Alivie la presión antes de inspeccionar o reparar cualquier filtración.
Alivie la presión cuando apague el pulverizador o deje de usarlo.
No use componentes cuya capacidad nominal sea inferior a la
presión máxima de operación del sistema.
No permita que niños usen esta unidad. Si se lesiona usando este
equipo, sométase de inmediato a tratamiento médico.

CAUTION
This symbol alerts you to the possibility of damage to
or destruction of equipment if you do not follow the
instructions.
Fluid injection is a serious injury! 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.
To help prevent injection, always:
Engage trigger safety latch when not spraying.
Point gun away from yourself or anyone else.
Relieve pressure before checking or repairing any leak.
Relieve pressure when you turn off the sprayer or stop spraying.

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
1. Lock gun trigger safety.
2. Turn engine ON/OFF switch to OFF.
3. Move pressure control switch to OFF and turn
pressure control knob fully counterclockwise.
CAUTION
For detailed engine maintenance and specifications,
refer to separate Honda Engines Owner’s Manual,
supplied.
DAILY: Check engine oil level and fill as necessary.
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.
AFTER THE FIRST 20 HOURS OF OPERATION
Drain engine oil and refill with clean oil. Reference
Honda Engines Owner’s Manual for correct oil viscosity.
WEEKLY: Remove air filter cover and clean element.
Replace element, if necessary. If operating in an
unusually dusty environment: check filter daily and
replace, if necessary.
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,
loosen tip guard retaining nut or hose end coupling to
relieve pressure gradually, then loosen completely.
Now clear tip or hose.
VERY SLOWLY
Replacement elements can be purchased from your
local HONDA dealer.
WEEKLY: 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.
AFTER EACH 100 HOURS OF OPERATION:
Change engine oil. Reference Honda Engines Owner’s
Manual for correct oil viscosity.
SPARK PLUG: Use only BPR6ES (NGK) or
W20EPR–U (NIPPONDENSO) plug. Gap plug to
0.028 to 0.031 in. (0.7 to 0.8 mm). Use spark plug
wrench when installing and removing plug.
