(c) Adjust throttle so that tachometer reads 1700 RPM (para 2-10).
NOTE
Tachometer reading must remain in the 1600-1700 rpm range when system is under load. If rpm
varies beyond these limits during calibration, the step being done should be repeated. Always use
chain oiler when conveyor is in operation.
(d) Place container under swivel ring to catch cement.
