rear and the table switch is fully engaged.
 Release both arms on the column lock. A firm snapping sound will be heard.
 Your sieve stack should fit very securely in the test chamber.
 Place the Column Stop in front of the entire assembly
If this has not solved the problem, visually inspect the Diaphragm and Fines Collector
for holes or tears and each sieve frame for cracks. Examine the Column Lock
springs. There should be six springs, all oriented vertically.
Lastly, setting the amplitude too high may also contribute to loss of the sample. Refer to question
three for instructions on setting the amplitude.
6. My VariSifter™ does not turn on or will run for a short time, then stop? What is happening?
The stack assembly must be fully inserted into the test chamber and locked in place by releasing the
Column Lock arms. Please refer to question five for instructions on properly assembling and
inserting the sieve stack assembly. If the column lock is not released, the stack is able to vibrate out
of position, releasing the table switch and turning the unit off. The table switch must remain fully
engaged in order for the unit to function.
7. Can the VariSifter™ be operated with the door open?
Yes. However, it is not recommended the door be wide open as it may alter your test results.
8. Why does the VariSifter™ have a light inside?
The light allows the user to set the proper amplitude. The sieves were designed with clear acrylic
frames so sample media can be viewed while the test is running. The appropriate amplitude has been
achieved when the largest particles of the sample are observed rolling on the sieve surface and none
arc higher than half the height of the sieve frame. Particles that are arcing too high will be forced
back into the sieve above, thereby altering the test results.
9. Does the VariSifter™ have to be calibrated?
No. The VariSifter does not come calibrated. The Frequency setting is a function of internal power
converter. Amplitude is an expression of percentage of power.
Test sieves, however, can be certified using W.S. Tyler’s sieve certification service.
10. What regular maintenance does the VariSifter™ require?
There is no routine maintenance required for the VariSifter™. It is recommended the unit be kept
clean by regularly wiping it down with a soft, damp cloth.
11. What is the warranty on the VariSifter™?
The VariSifter™ carries a one-year limited warranty against defective material and workmanship.
12. Can I use 3” brass sieves in my VariSifter™?
No. The VariSifter™ is designed only for use with 3” acrylic sieves and the diaphragm and fines
collector. Metal 3” sieves are not compatible.
