WARNING - Before adjusting eccentric weights, turn off and lock out/tag out energy source
to vibrator.
CAUTION - Do not operate vibrator with end caps removed. Dust accumulation around
vibrator shaft could cause unit to fail.
CAUTION - Adjust both sets of eccentric weights to same setting number mirror images, or
force output will be uneven and damaged vibrator.
WARNING - Vibrator may produce loud noise during operation. See OSHA 1910.95 for
guidelines and required, wear ear protection to avoid impairment or loss of hearing.
CAUTION - Do not allow motor to exceed nameplate rating. If vibrator operates
continuously at above rating damage may occur.
4. OPERATION
The following chapter addresses the operation, mechanical adjustments and material flow of the system.
The system uses several variables that allow the sifter to perform at optimal throughputs such as the
rotary motor and vibration dampeners. Vibratory sifters operate by rotary motors which use counter
weights rotating at high RPM to produce the vibratory force required to move material across the wire
mesh. Paired with the vibration dampening rubber mounts the system works in unison together, while
the rotary motors deliver the centrifugal force outwards the vibration dampeners give the elasticity
that allows the housing to vibrate at the right force frequency. The weights within the motors can be
adjusted to change the force frequency and speed the material travels across the screen. For instructions
on adjusting the force frequency, please refer to section 4.1.1. and for any other questions contact HK
Technologies at [phone].
The following are notices to safety requirements that the reader should take note of before operating and
maintaining the equipment. The reader should know these general warnings:
• Warning - indicates a hazardous situation that if avoided can result in serious death or
injury.
• Caution - indicates a hazardous situation that if avoided can result in minor of moderate
injury.

4.1.1 ADJUSTING MECHANICAL OPERATIONS
If mechanical adjustments are required read the following as it instructs how to set weights of the
rotary motors when fine tuning to the ultrasonic pulses. Adjusting weights in the rotary motor
control the rate at which the product moves and feeds around the screen.
Adjusting Mechanical Operations
Step Instruction
1 Disconnect all power of unit before removing motor covers.
2 Remove the motor enclosure if included.
3 Remove the four bolts on the top cover
4 The top two weights maybe loosened by the hex head nut on the outside edge.
5 Notice the weights are fixed around the shaft and can be rotated 360 degrees.
6 For product to move quickly to outside edges align the weights to 100% as shown in Fig. 4.1
7 For product to move slowly to the outside edge rotate the lower weight to 50% as shown in
Fig. 4.2
8 For product to remain at center during cycle rotate the lower weight to 0% as shown in Fig.
4.3
9 After finding the right weight balance that works for your set-up tighten the nut to specified
torque on the weights to hold in place during cycle.
10 Replace the motor cover and tighten nuts to specified torque before turning on motor.
11 Replace motor enclose and connect power to start sieve.
12 *Special Note: Ensure both weights are set to identical weight balances

4.2.1 FEEDING AND MATERIAL FLOW OPERATIONS
The sifter material will be fed into the top of the machine through the inlet hole at the center of
the housing when the vibrator is on. This should be done by plastic tube (not included) over the
outer diameter allowing material to pour in at a steady rate. The screen should be covered with
1/8” deep of the material. The now in-process sifting material should move across screen while
smaller pieces pass through the mesh and large pieces remain on top see Fig. 4.4.
