AIRLESSCO SS4550 - Manual (Page 12)

STRAIGHT LINES
a. SS6050: Loosen the two ratchet handles on the swivel
wheel assembly, just enough to be able to move the
assembly by hand. Lift the ratchet handle to move the
handle without turning the attached bolts, then press
down and turn handle counterclockwise to loosen.
SS4550: Stripers are factory aligned, but if necessary,
loosen the two bolts (fig. 35, item 19) on the swivel
wheel assembly, just enough to be able to move the
wheel by hand. Align wheel and re-tighten bolts.
b. Place the turnbuckle over the two mounting nubs on the
frame.
c. Pressurize the unit with water and Airlessco's Pump
Conditioner and spray out several lines with the swivel
assembly in the locked position. Use the turnbuckle to
fine tune the alignment of the wheels, until the stripes
are straight.
IMPORTANT: Loosen ratchet handles prior to
any turnbuckle adjustment.
d. Tighten the jam nuts on the turnbuckle to affix the
turnbuckle length for future reference.
e. Tighten the ratchet handles (6050) or bolts (4550.)
CURVES AND ARCS
Basically the same as above, except the swivel wheel
assembly is set at angle. The swivel assembly can be
adjusted to 30 degrees either side of straight ahead. If
you have arcs that you paint regularly, purchase additional
turnbuckles (PN. 136-231) and keep them set to those arc
sizes.
LINE STRIPING OPERATION
There are 4 holes in the frame on the 4550 & 6050. In a
standard set up, the gun arm would be mounted in the right
hand near the single wheel. This allows for an easier visual
check for straight line striping and for basic arc striping.
a. Ensure that striping tips are in the guns.
b. Pick a tip size for the desired line width.
EXAMPLE: a 317ST tip for a four inch line.
c. Place gun into the gun holder, so that the top of the
taper on the gun handle is flush with the edge of the
gun holder.
d. Set gun height for the desired line width. Adjust height
by loosening the small black handle on the gun holder
assembly and slide the gun arm to the correct height.
Now tighten the handle. This will require some
experimentation to find the correct height. It is suggested
that tape, or some other method is used to mark the
height of commonly used settings.
e. Set spacing between the two guns by loosening the
black handle on the gun arm. Slide to the desired width
and tighten.
f. Attach the swivel heads to the guns if painting curbs
or wide stripes.
g. Angle the guns slightly forward. This allows the spray
pressure from the guns to help blow dirt and debris out of
the path of the new stripes.
Once the handle and gun arm assemblies are set up to the
preferred positions, pressurize the unit and trigger each
gun to ensure that they activate and release correctly. If
not, adjust the cable tension as follows:
a. Locate the adjustment knobs on the base of the gun
trigger, where the cable connects to the gun trigger
assembly.
b. Loose the locking nut and move the adjusting screw until
the slack has been removed from the cable.
c. Tighten locking nut and retest gun triggers for proper
function.
NOTE: THERE IS AN ADDITIONAL CABLE
ADJUSTMENT WHERE THE CABLE ATTACHES TO
THE GUN HOLDER ASSEMBLY. USE ONLY IF THE
GUN TRIGGER ADJUSTMENT IS INSUFFICIENT.
a. CURBS: Adjust gun to desired height and turn swivel
head towards curb.
b. WIDE STRIPES: Install wider fan striping tips and raise
the gun height to achieve the desired width line. Also
angle guns slightly towards each other to get an even
coat of paint.
c. STENCILS: Install standard spray tip on the outer gun.
Remove this gun from the gun holder and spray out the
stencils.
d. STANDARD PAINTING: Same as stencils, but use
additional paint hose as required.
