Model-200 Test Sieve Shaker Operation Instruction




1.Prior to operate the laboratory test sieve shaker , please make sure all the components are fastened, no broken on the sieves, no damage on the machine, electrical cables are connected properly.
2.Power supply is the same as shown on the 
test sieve machine plaque.
(Tolerance for voltage is ± 10%)
3.Keep all parts in place at all times to avoid exposure to parts rotating at high speeds. While the power of 
 laboratory test sieve shaker is on, severe injury can occur if hands or feet reach inside the unit.
4.When installing or maintaining this test sieve shaker, shut off and lock out power. Follow all local and national electrical codes. Failure to do so could result in severe personal injury or property damage.
5.Higher amplitudes occur during shut down and start-up 
laboratory test sieve shaker. Stand clear of unit and keep accessory equipment away during these cycles.


1.Securely tighten all nuts and bolts on the unit. Pay special attention to the motor mounting bolts. If a motor vibrates loose, damage to the power cord and to the structure may result as well as risk of personal injury.
2.Do not operate instrument with more than quantity of weight we recommended. Overloading the top and bottom weight assemblies will place excessive load on motor bearings which can cause permanent damage to the motor and to the instrument.
3.Never run motor with weights exposed. Failure to do so could result in severe personal injury or property damage.
4.Screens are fragile. Handle with care. Never place tools or parts on the screen or damage to screen may occur.
5.The noise level produced by this equipment may not be acceptable to your environment. Take every precaution to make certain that safe noise levels are met.
