Octagon 200
General Information
The sieve shaker Octagon 200 is suitable for all sieving tasks in laboratories as well as onsite and
provides optimum sieving action for fast and reproducible results.
It is robust, compact and sufficiently lightweight to be portable. Its electromagnetic drive combined
with a 3D sieving motion ensures excellent separation efficiency in a short amount of time.
A digital display as well as a quick-release clamping system makes operation very easy and
straightforward.

Controls and functions
The sieve shaker should be placed on a level surface to ensure symmetrical distribution of the sample
over the sieve mesh. The surface should be rigid and robust where vibration will not cause problems.
Operators should be familiar with and fully understand the controls and indicators before
operating this machine. This should be done in conjunction with the diagram below and control
panel description.

1. Setting up
Setting Up
Electrical connections
* The voltage and frequency for the Octagon 200 is
given on the rating label.
* Ensure that the values agree with the existing power
supply.
* Connect the Octagon 200 to the power supply using
the connection cable provided.
* When connecting the power cable to the mains
external fusing is necessary according to the
regulations of the installation location
Do not connect to any other supply other than stated on the rating label,
otherwise electrical and mechanical components can be damaged.
Ambient temperature: 5°C to 40°C
If the ambient temperature is exceeded or drops below the specified value
the electrical and mechanical components may become damaged and the
performance data can change to an unknown degree.
Atmospheric humidity:
Maximum relative humidity 80% at temperatures up to 31°C, with linear
reduction down to 50% relative humidity at 40°C.
At high atmospheric humidity the electrical and mechanical components
may become damaged and the performance data can change to an
unknown degree.

Transport protection
Place the Octagon 200 on a stable laboratory bench, since otherwise unpleasant vibrations will
be transmitted. Being placed on a level surface ensures symmetrical distribution of the sample
over the sieves, during operation.
xUnscrew the two hexagon screws (transit bolts) on the bottom of the sieve shaker with
an open ended spanner until the sieve plate is movable.
xKeep hexagon screws (transit bolts) for possible transport at a later date.
If the machine is operated with the transit bolts, or is transported without
transit bolts, mechanical components may become damaged.
Reusing transit bolts
xDismount the clamping unit.
xScrew the hexagon screws (transit bolts) into the two holes on the bottom of the sieve
shaker and tighten with open ended spanner until the sieve plate is no longer movable.

1. Setting up
Mount sieve clamping unit
Fit one M12 nut onto each clamp rod selected for use, then
screw the pair of clamp rods into the location plate and tighten
the locknuts.
Place the two large plain washers over the 20 mm threads of the clamp sleeves. These can be seen
protruding vertically from the two side lugs on the clamp plate. Screw the two hand wheels
loosely onto the 20 mm threads; leave a gap of 5 mm between the large washer and the hand
wheel face. Do not tighten right down at this point.

Operating Instructions
1. Place the receiver centrally on the location plate in the appropriate recess.
2. Stack the required test sieves on top of the receiver (min. 1x receiver + 2x sieves + 1x lid).
3. Put the sample in the top sieve and fit the lid
In order to guarantee exact results under fast sieving conditions, the quantity of material to be sieved
should be adapted to the sieve diameter and the nominal mesh size.
More detailed information is displayed in our “TEST SIEVING MANUAL”.
4. Align the locking assemblies in figure 1 the two side lugs of the clamp plate with the round
clamp rods. Slide the clamp plate down squarely onto the lid at the top of the sieve stack.
Ensure that the clamping hand wheels at the top (figure 2) are loose and the locking assemblies are
fully pushed down. There should be a 5mm gap between the large plain washer and the face of the
hand wheel.
Place one hand on the top of the clamp plate (figure 3) and hold square while locking one side handle
lever. Repeat for the opposite side handle lever.
The side handle levers can be set vertically downwards by pressing on the Red button and pulling
the handle outwards to release (figure 4). Turn the handle to a safe, convenient angle downwards and

release to engage the teeth. Screw the two clamping hand wheels down simultaneously to ensure the
clamping plate is square.
Continue until the hand wheels are tight against the internal stop. Hand tightness must be exerted so
that the assembly does not loosen during vibration.
The locking side handle levers and clamping hand wheels must be tightened sufficiently to ensure
that the sieves and receiver are clamped securely during operation.
5. Set time, interval and amplitude.
6. Press START
Damage may occur if the shaker is allowed to operate with a loose clamping plate.

Wet sieving
The Wet Sieving Adaptor Kit is supplied as an optional extra for 200 mm or 8” diameter sieves and
should be ordered separately.
The Wet Sieving Adaptor Kit consists of the following items:
x1 off Special Wet Sieving Clamp Plate.
x1 Set off O-ring Seals (One required for
each sieve in the stack.)
x1 off Special Wet Sieving Receiver with a spout.
(Specify for 200 mm or 8” diameter sieves )
The O-ring seals are fitted on to the outside of the bottom rim of each sieve, which means the
sieves are stacked onto each other and they form a seal.
The bottom sieve is placed on the special receiver with a spout.
A nylon hose tail must be fitted and must have a suitable length of hose fitted to drain into a
convenient drainage point.
Fit a suitable length of hose to the spout to drain into a convenient drainage point.
The clamp plate is usually supplied with the rose reversed to avoid damage. Undo and reverse,
so that the rose head is on the inside. Remove the lid from the sieve stack and replace the standard
clamp plate with the wet sieving clamp plate. Fit a suitable length of hose to the inlet of the rose on
the clamp plate and connect to the fluid supply with flow regulation.
Never operate your Sieve shaker directly in water.
Danger through current surge.
During wet sieving always operate your Sieve shaker connected to a mains socket
protected by an FI protective (safety) switch.
The water quantity added should always be dosed in such a way that the sieve
surface is only just wetted.
