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 the engine manufacturer. There are two
types of "gasohol": one containing ethanol, and the other
containing methanol. Do not use gasohol that contains more
than 10% ethanol. Do not use gasoline containing methanol
(methyl or wood alcohol) that does not also contain co-
solvents and corrosion inhibitors for methanol. Never use
gasoline containing more than 5% methanol, even if it has co-
solvents and corrosion inhibitors.
Startup
1. Areas must be well ventilated to prevent hazardous
operation with volatile solvents or exhaust fumes.
If lacquer or other flammable materials are to be sprayed,
ALWAYS locate the unit outside the immediate spraying
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 “Hydraulic
System” in the Maintenance section of this manual for
changing or adding hydraulic fluid. Do not overfill. Use
only Speeflo Coolflo™ Hydraulic Fluid (P/N 430-361).
b. The gasoline engine oil level is determined by the
manufacturer. Check the manufacturer's service
manual supplied.
Use of Speeflo's Coolflo™ Hydraulic Fluid is mandatory in
the PowrTwin 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-handled hydraulic shut-off valve located on
the hydraulic pressure hose. The handle should be in line
with the hose. The figure below shows the handle in the
open position.
CAUTION
NOTE: Fuel system damage or engine performance
problems resulting from the use of fuels that
contain alcohol is not covered under the
warranty. The engine manufacturer cannot
endorse the use of fuels containing methanol
since evidence of their suitability is incomplete
at this time.
Before buying gasoline from an unfamiliar
station, try to find out if the gasoline contains
alcohol. If it does, confirm the type and
percentage of alcohol used. If you notice any
undesirable operating characteristics 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.

5. Turn the pressure control knob counterclockwise (as
viewed from top) to its lowest pressure setting.
6. Open the pressure bleed valve by turning it
counterclockwise. This relieves pressure.
a. Your new sprayer was tested at the factory with mineral
spirits. You must clean the system before spraying to
avoid contamination 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 the pressure
control adjustment knob clockwise (increasing
pressure) until pump cycles evenly and solvent flows
freely from bleed line.
d. Close the pressure bleed valve by turning it clockwise.
This allows the system to pressurize. Hold the gun
trigger open, without spray tip attached, until the fluid
flows smoothly.
7. Repeat above starting procedure with paint material. Lock
gun trigger and attach spray tip. Refer to the spray gun’s
Technical Data Sheet or Owner's Manual for tip installation
and selection of the proper tip size.
8. Test spray pattern. Operate the pump at the lowest
hydraulic pressure which provides good atomization. See
the Troubleshooting section in this manual if you are not
getting the proper pattern.
9. Operating pressure is adjustable from 400 to 3300 psi
(228 bar) by turning the pressure control 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 the
pressure control adjustment knob and the pressure bleed
valve.
