Operation
Setting Screed End Gates
1. On the rst pass, turn the endgate depth screw
(Figure 6-14,1) to lower the end gate until it is about
0.25 in. (6.35 mm) below the screed.
NOTE: Most operators run end gates within 0.25 in.
(6.35 mm) of ush.
2. Turn the tilt screw (Figure 6-14,2) on the end gate
so the front of the end gate tilts down slightly when
the screed is lifted. This will allow the end gate to set
itself to grade.
NOTE: When paving, never let the end gate carry the
weight of the screed. This will cause screed
compaction to vary.
3. During operation, if the end gate starts to dig in at
front, adjust the tilt screw so the end gate tilts back.
4. When making a joint, the end gate must be set to
where it ts ush with bottom of screed.
NOTE: Keep runners clean. When making a joint, spray
cleaning solvent on runners (Figure 6-14,4).
Fire Hazard! Never spray cleaning
solvent or release agent on or near a screed heating
element that is hot or being heated or on or near any
open ame or ignition source. Cleaning solvent and
release agent could ignite causing serious personal
injury.
5. On the rst pass, leave about 6 - 8 in. (15 - 20 cm) of
unrolled asphalt where the joint is being made.
6. In laying a joint, if the joint looks too high or too low,
adjust the tilt screw (Figure 6-14,2) on the screed
about one (1/4) turn at a time and allow 4 - 5 ft. (1.2 -
1.4 m) of travel to correct itself.
NOTE: Too much adjustment up or down may cause
rising and falling effect in the paved material.
7. If making a cold joint, set end gate down about 0.25
in. (6.35 mm); this will give a nice, even edge.
