UPPER HANDLE INSERTION THROTTLE ASSEMBLY LOCATION Correct FASTENING UPPER HANDLE THROTTLE ASSEMBLY Place the throttle lever on the left hand handle just below the hand grip. Position the lever so it clears the handle guard in all positions.
LEAST VIBRATION THROTTLE ASSEMBLY CONNECTION Turning the thin weight counter clockwise increases the force of vibration until the flat edge of the thin weight is flush with the opposite edge of the thick weight. With the throttle lever pushed to the far right hold the throttle adjustment cable so there is no slack and then tighten throttle control adjustment screw to clamp the cable in place. WEIGHT ADJUSTMENT The eccentric weight on the power head is factory set to its maximum force.
THROTTLE CABLE ADJUSTMENT The throttle cable on the Screed King comes preassembled for your convenience. Over time you may notice that it takes more clicks on the throttle to get to optimum RPM level than when you first ran the screed. This is normal, over time your throttle cable will stretch. To adjust your throttle cable to compensate for this stretching, simply locate the barrel adjuster where the cable runs into the underside of the engine and turn it counterclockwise with a 8 mm wrench.
