Figure 10: Cutting the tape
Tamping
After applying the pavement marking tape tamp it
thoroughly with the RTC-3 with a minimum 90kg
(200lb.) load.
When using the RTC-3 Roller Tamper Cart:
• Do not twist or turn the tamping device on the tape.
• Make three passes back and forth over each part of
the tape
• Move the RTC-3 slowly (4-5 km/h) over the tape
• Make sure all edges are firmly adhered
• If applying block markings or pedestrian crossings,
start in the center of the marking, then work towards
the edges to remove trapped air.
• Open road to traffic as soon as tamping is completed
Tamping is most important !
Maintenance
Keep all Fasteners Tight
Lubrication: The pivot points and sliding areas should
be kept lubricated with light oil.
Cleaning: The silicone application roller wheels and
cutting mechanism must be kept clean.
Mineral spirits, fuel oil or any other light oil cleaners
may be used on the wheels and knives.
Check knife blades from time to time to prevent adhesive
build-up.
Solvents may be used occasionally for difficult cleaning
problems. A spray bottle of cleaner or silicone spray is
useful to prevent asphalt and dirt pickup on the wheels
and adhesive buildup on the knives during operation.
Caution: Do not use solvents or petroleum products on
the silicone application roll when working on new, hot
asphalt surfaces.
To prevent asphalt buildup around the roller, untighten
the scraper mounting screws and move the scraper back.
Tighten the screws.
Adjustments
The Knifes are pre-adjusted by the manufacturer to slide
across each other with a minimum of friction in a scissors
action. Adjustment is needed when the tape is not
properly cut.
Either the stationary knife or the sliding knife may be
adjusted. To adjust the stationary knife, untighten the
mounting screws slightly. Turn the setscrews to bring the
cutting edge down, and retighten the mounting screws.
The same procedure is followed to adjust the sliding
knife. Each knife has two cutting edges. The knives may
be removed and new cutting edges exposed. The knives
may be sharpened after the cutting edges are dull.
Trouble Shooting
Tape is not properly cut: The tape will not cut cleanly if
cutting is done while the applicator is in motion. If the
knife edges are dull or out of alignment, the knives
should be sharpened and adjusted. (See Adjustments).
Clean adhesives build up from knives. (See
Maintenance).
