Fire and explosion hazard: Solvent and paint fumes can ignite or explode.
To help prevent a fire and explosion:
DUse only in an extremely well ventilated area.
DEliminate 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.
DGround Sprayer, object being sprayed, paint and solvent pails.
DHold gun firmly to side of grounded pail when triggering into pail.
DUse only conductive airless paint hose.
DDo 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 reac-
tion, with the possibility of explosion.
DDo not fill fuel tank while engine is running or hot.
DDo not flush with gasoline.
Fluid injection and high pressure hazard: High pressure spray or leaks can inject fluid into the body.
To help prevent injection, always:
DEngage trigger safety latch when not spraying.
DKeep clear of nozzle and leaks.
DNever spray without a tip guard.
DDo PRESSURE RELIEF if you stop spraying or begin servicing sprayer.
DDo not use components rated less than sprayer Maximum Working Pressure.
DNever 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.
WARNING
Exhaust hazard: Exhaust contains poisonous carbon monoxide which is odorless and colorless. This
equipment must be used in well ventilated work areas only.
Alcohol and drug hazard: Do not operate this equipment under the influence of alcohol or while taking
medication that impairs your senses or reactions.

Pressure Relief Procedure
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.
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.
DAILY: 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.
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.
AFTER THE FIRST 20 HOURS OF OPERATION:
Drain engine oil and refill with clean oil. Reference
Honda Engines Owner’s Manual for correct oil viscos-
ity.
AFTER EVERY 25 HOURS OF OPERATION:
The hour meter will flash SVC (service). When flash-
ing:
Dchange engine oil using SAE30 or 10W–30 deter-
gent oil.
DInspect pump’s inlet ball checks for nicks, scratches
or damage which would prevent a good seal.
Replace if worn.
DInspect pump rod and pump sleeve for excessive
wear. Replace if needed.
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.

Installation
WARNING
If pin (44) works loose, parts could break off due to
force of pumping action. Parts could project
through the air and result in serious injury or prop-
erty damage. Make sure pin (44) and retaining
spring (45) are properly installed.
CAUTION
If the pump locknut loosens during operation, the
threads of the bearing housing will be damaged.
Make sure locknut is properly tightened.
