Warnings and Cautions
Warning Symbol
WARNING
This symbol alerts you to the possibility of serious
injury or death if you do not follow the instructions.
WARNING
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 reaction, with the possibility of explosion.
DDo not fill fuel tank while engine is running or hot.
DDo not flush with gasoline.
Caution Symbol
CAUTION
This symbol alerts you to the possibility of damage to
or destruction of equipment if you do not follow the
instructions.
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
spraye r.
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 surgical
treatment.

† Best for use with LineDriver.
# Best for cold weather applications.
How to Maximize Line Quality and Reduce Tip Wear. Observe the following suggestions to increase line quality
and minimize sprayer tip wear.
1. Select a larger tip orifice and run the sprayer at a reduced operating pressure.
2. Running larger tip sizes (example: use tip LL5321 @ 2000 psi instead of LL5317 @ 3300 psi) will significantly
increase tip life and reduce tip plugging. It will also produce a more uniform film build across the line.

WARNING
Maintenance
DAILY: Check pressure drain valve for proper opera-
tion.
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:
D areinstructedtorelievethepressure,
D stop spraying,
D check or service any of the system equipment,
D 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 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.
DAILY: Check and fill the gas tank.
AFTER THE FIRST 20 HOURS OF OPERA TION:
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.
Repack connecting rod (22) top needle bearing after
every pump change.
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.
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 SLOW LY
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.
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.
Caster Wheel
(See letter call-outs in Parts drawing on page 22)
1. Once each year, tighten nut (164m) until spring
washer bottoms out. Then back off the nut 1/2 to
3/4 turn.
2. Once each year, tighten nut (62) until it begins to
compress spring washer. Then tighten the nut an
additional 1/4 turn.
3. Once each month, grease the wheel bearing (F).
4. Check pin (164e) for wear. If pin is worn out, there
will be play in the caster wheel. Reverse or replace the pin as needed.
5. Check caster wheel alignment as necessary.
To align: loosen bolt (164t), align wheel and tighten
bolt (164t).
