Gasolines containing alcohol:
If you decide to use a gasoline containing alcohol (gasohol), be
sure its octane rating is at least as high as that recommended by
Honda. There are two types of "gasohol": one containing ethanol,
and the other containing methanol. Do not use gasohol that con-
tains more than 10% ethanol. Do not use gasoline containing
methanol (methyl or wood alcohol) that does not also contain
cosolvents and corrosion inhibitors for methanol. Never use gaso-
line containing more than 5% methanol, even if it has cosolvents
and corrosion inhibitors.
NOTE:
Fuel system damage or engine performance problems
resulting from the use of fuels that contain alcohol is not covered
under the warranty. Honda cannot endorse the use of fuels con-
taining methanol since evidence of their suitability is as yet incom-
plete.
Before buying fuel from an unfamiliar station, try to find out if
the fuel contains alcohol, if it does, confirm the type and percent-
age of alcohol used. If you notice any undesirable operating sys-
tems while using a gasoline that contains alcohol, or one that you
think contains alcohol, switch to a gasoline that you know does not
contain alcohol.
STARTUP
1. Areas must be well ventilated to prevent hazardous operation
with volatile solvents or exhaust fumes.
WARNING:
If lacquer or other flammable materials are to be
sprayed, ALWAYS locate the unit outside the immediate spray-
ing area. Failure to do so may cause an explosion.
2. Locate the unit outside the immediate spraying area to avoid
clogged air intake of the engine or electric motor with overspray.
3. Before starting the unit, check oil levels.
A. The hydraulic fluid level should read "Full" on the dipstick.
CHECK IT REGULARLY. See the Hydraulic System
Maintenance Instructions on Page 11 for changing or adding
hydraulic fluid. Do not overfill. Use only Titan/Speeflo Coolflo™
Hydraulic Fluid, Part No. 430-361.
B. The gasoline engine oil level is determined by the manufacturer.
Check the manufacturer's service manual supplied.
IMPORTANT NOTE: Use of Titan/Speeflo's Coolflo™ Hydraulic
Fluid is mandatory in the PowrTwin 3500™ hydraulic system.
Do not use any other hydraulic fluid. Use of any other
hydraulic fluid may seriously damage hydraulic system and
will void warranty.
4. Open the orange handle shut-off valve located on the hydraulic
pressure hose. Handle should be in line with hose. Figure 3 shows
the handle in the open position.
5. Turn the Pressure Adjustment Knob counterclockwise (as
viewed from top) to lowest pressure setting. See Figure 3.
6. Open the Pressure Bleed Valve by turning it counterclockwise.
This relieves pressure. See Figure 4.
A. Your new sprayer was tested at the factory with mineral spirits.
You must clean the system before spraying to avoid contam-
ina-
tion of the
sprayed
material.
If you are spraying a water based latex, flush with warm, soapy
water followed by a clean water rinse. If you are using any other
coating, flush with warm, soapy water followed by a solvent. Check
with the material manufacturer for a compatible solvent.
Place syphon tube assembly into proper solvent or water.
B. Place waste container below bleed line.
C. Start engine or electric motor. Turn Pressure Control
Adjustment Knob clockwise (increasing pressure) until pump
cycles evenly and solvent flows freely from bleed line.
D. Close Pressure Bleed Valve by turning it clockwise. This
allows the system to pressurize. Hold gun trigger open, without
spray tip attached, until the fluid flows smoothly. See Figure 4.
7. Repeat above starting procedure with paint material. Lock gun
trigger and attach spray tip. See the Technical Data Sheet or
Operator's Manual on the gun provided for installation and selec-
tion of the proper tip size.
8. Test spray pattern. Operate the pump at the lowest hydraulic pres-
sure which provides good atomization. See the Troubleshooting
Guide if you are not getting the proper pattern.
9. Operating pressure is adjustable from 400 to 3000 psi (207 bar)
by turning the Pressure Adjustment Knob clockwise. Do not turn
the knob clockwise more than necessary to provide satisfactory
atomization. Excess pressure wears out spray tips.
10. When restarting the unit, reduce the pressure at Pressure
Control Adjustment Knob and Pressure Bleed Valve.

FLUSHING
IMPORTANT -- PRESSURE RELIEF PROCEDURE
ALWAYS reduce pressure when you are cleaning a clogged
tip, changing a tip, servicing any part of the system, or shut-
ting down. Follow the steps below:
1. Engage the gun trigger lock.
2. Shut off the power source.
3. Close the orange handle shut-off ball valve on the hydraulic
pressure hose.
4. Open the Pressure Bleed Valve by turning it counterclock-
wise at least three full turns.
5. Disengage the gun trigger lock and hold trigger open until
flow of material stops.
6. Be certain to hold a metal part of the gun firmly to the side
of a grounded metal container.
CLEANING A CLOGGED TIP
1. Follow the Pressure Relief Procedure above.
2. If tip clogs, rotate tip handle 180° until arrow on handle is facing
the opposite of spray direction and clicks in reverse position.
3. Trigger gun once so that the pressure can blow the clog out.
NEVER
use the tip in the reverse position for more than
ONE
trig-
ger pull at a time. This procedure can be repeated until the tip is
free of clogging.
WARNING:
THE FLOW FROM THE SPRAY TIP IS AT VERY
HIGH PRESSURE. CONTACT WITH ANY BODY PART MAY BE
DANGEROUS. DO NOT PLACE FINGER ON GUN OUTLET. DO
NOT POINT THE GUN AT ANY PERSON. NEVER OPERATE
THE SPRAY GUN WITHOUT THE PROPER TIP GUARD.
