Remove the cover from the tank, and wipe it out with a clean cloth. This process will get most of the
paint out of the tank. Replace the cover and pour enough thinner into the tank to cover the fluid outlet,
which leads to the spray guns, and apply pressure to the spray gun on the tank. Open the compressor
engine controls (this will apply pressure and force the thinner through the fluid line and spray gun).
Drain the fluid that is left in the paint tank and remove the cover. Wipe out the tank and clean all
external units.
3-21. Storage. When storing a paint gun or traffic-marking equipment, perform the following:
a. Paint Gun. Remove the gun, disassemble it, and clean the parts thoroughly after each use.
b. Bead Dispenser. Lubricate the dispenser's moving parts frequently.
c. Driving Units. Check belts and drive chains frequently for wear. Lubricate the chains, as
required.
d. Wheel Bearings. Check the bearings for adjustment and lubricate them when necessary.
e. Tires. Inflate the tires to the proper pressures.
f. Grease Fittings and Oil Cups. Grease and oil various units by using the grease fittings and
the oil cups provided for this.
g. Machine Storage. Store the machine in a sheltered place when it is not in use.
3-22. Glass Bead-Dispensing Gun. This gun is used whenever glass beads are to be embedded in
traffic paint that has been applied with a paint brush or a spray gun instead of a traffic marker. The gun
is actually an air pump, which is an accessory of the glass bead-dispenser hopper. When it is filled with
glass beads and the handle is moved back and forth, the gun jets a uniform glass bead spray. For a light
bead distribution, the gun is held so that the discharge chute is at the top, then as the gun is turned in a
clockwise direction, the glass-bead distribution increases. These glass beads reflect light when applied
to curbs, lane-markings, and runways.
3-23. Laminated-Backed Adhesive. Laminated-backed adhesive is another item used to mark traffic
lanes so that they are easily seen at night. This material is flexible, may be cut to form such items as
letters or numbers, and comes in various colors.
