Controls description
The control panel of the shaker consists of the following elements:
Setting regimes of operation
The operation regime is set by adjusting two parameters:
RPM - Platform rotation speed.
TIME –Platform rotation time, timer turn off.
Choose the desired parameter buy pressing mode button. The light indicator will
show which parameter is selected.
Set the desired parameter value.
If the time parameter is less than 1 minute, the timer automatically switches off and
the display will show OFF message.
Launch the operation with start / stop button. If you wish to end the operation before
the estimated time runs out press the start / stop button again.
All the TIME and RPM parameter settings are stored in the power independent
memory.

Unpacking and setting up
Before turning the machine on, please take a look at the adapter. Ensure that the
wire and the body of adapter are not damaged. In case of external damage of the
adapter, do not plug it in the machine without the supervision ofspecialist!
1) Plug the adapter into the outlet. The indicators on the control panel will turn on.
2) Set up the desired operation regime: rotation time andspeed.
3) Press the start button. The platform will start to move. When the desired time will
run out, the shaker stops and gives the sound signal.
4) During rotation on the display time counts down in minutes and when the last
minute is left the shaker starts the countdown in seconds.
5) When the shaker is operating the time parameters cannot be changed. By
pressing the control buttons shortly, the indicators will show the set time
period.
6) The rotation speed can be changed during the rotation of platform by pressing
the control buttons.
7) The shaker automatically protects itself from the overloading. If during the
operation the platform is overloaded or there is an other obstacle, the platform halts
and attempts to start again until the obstacle isremoved.
