Description
____________________________________
The Endecotts EFL 2000 is a vibrating shaker that is used to carry out
sieve tests in conjunction with sieve stacks for particle sizing of various
material samples.
It is based on a rotary motor with an eccentric cam drive with special
non-metallic laminated springs that are set at a calculated angle to
provide a horizontal twist, as well as a vertical movement to carry out
efficient sieve tests.
The EFL 2000 range are fixed amplitude shakers.
An incremental timer provides a range of pre-set
and repeatable sieve test run times.
The EFL is fully EMC and LVD
compliant and complies with all
relevant European directives.

Unpacking
________________________________________________
The shaker should be set up according to the following procedure and
the diagram opposite. The Internal packing and following list of items
should be removed from the case and checked before the EFL 2000 is
removed.
1 off Test Sieve Shaker EFL 2000
2 off M12 Plated Lock Nuts
2 off M12 Plated Plain Washers
2 off Clamping Handwheels
2 off Large Plain Clamp Washers
2 off Clamping Handwheels
1 off Clamp Plate Assembly complete
with Locking Assemblies
4 off Anti-Vibration Mounts
4 off M10 Large Washers
1 off Mains Cable

2 off Short Clamp Rods SA 564/3
2 off Long Clamp Rods SA 564/2
Keeping top opening of packing case uppermost unscrew transit bolts
from underside of case (placing blocks under packing will assist
this operation). Lift the shaker from packing case carefully. The anti-
vibration mounts should be screwed into the four tapped holes provided
on the underside of the underside of the machine and adjust the feet to
level the shaker then tighten the lock nuts.

Setting Up
________________________________________________
Assembly
The machine should be positioned on a level rigid and robust floor
suitable for the operation of the sieve shaker, (placing the shaker on a
level surface ensures the even distribution of the sample over the sieves
and ensures machine stability).
Take Care as the shaker weighs 83 Kg

________________________________________________
Clamping Assembly
Fit one M12 nut and washer 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 20mm threads of the clamp
sleeves. These can be seen protruding vertically from the two side lugs
on the clamp plate. Screw the two handwheels loosely onto the 20mm
threads, leave a gap of 3mm between the large washer and the
handwheel face. Do not tighten right down at this point.
See Diagram below:

Setting Up
________________________________________________
Electrical Connections
Ensure that the voltage and frequency on the Rating Label, at the rear of
the shaker correspond with the local electrical mains supply. If there is
any discrepancy, please consult your supplier or a qualified electrician.
Do Not Connect to any other supply other than that stated
on the Nameplate
Important – This equipment must be connected to mains earth
The EFL sieve shaker is provided with a detachable 2 metre long mains
cable which has an IEC moulded connector at the shaker end and plug
suitable for connecting to the local mains supply. Certain models may
be supplied with a fused plug. In the event of failure the fuse must be
replaced with a fuse of identical rating.

________________________________________________
Sieve Stacking
The EFL 2000 shakers accommodate up to the following number of
sieves in a stack plus the required lid and receiver:
Model: Height: 300mm/12 inch 200mm/8 inch 100mm/3
inch
EFL Full Not Applicable 8 12
2000/1 Half Not Applicable 18 24
EFL Full 6 12 16
2000/2 Half Not Applicable 24 32
All sieve stacks require the necessary lid and receiver.
The recesses in the location casting will accept the following sieve
diameters.:
EFL 2000/1:
200mm/8 inch, 150mm/6 inch, 100mm/4 inch or 3 inch
EFL 2000/2:
300mm/12 inch, 200mm/8 inch, 150mm/6 inch, 100mm/4 inch or 3
inch
Place the receiver centrally on the location casting in the appropriate
recess. Stack the required sieves on top of the receiver. Put the samples
in the top sieve and fit the lid.

Sieve Stacking
Align the locking assemblies in 1.
the two side lugs of the clamp
5mm
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 2.
handwheels at the top 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
handwheel.
Place one hand on the top of 3.
the clamp plate and hold
square while locking one side
handle lever. Repeat for the
opposite side handle lever.

Setting Up
________________________________________________
Sieve Stacking
The side handle levers can be 4.
set vertically downwards by
pressing on the Red button
and pulling the handle
outwards to release. Turn the
handle to a safe, convenient
angle downwards and release
to engage the teeth.Screw the
two clamping handwheels
down simultaneously to ensure the clamping plate is square. Continue
until the handwheels 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 handwheels must be
tightened sufficiently to ensure that the sieves and receiver are clamped
securely during operation. Damage may occur if the shaker is allowed
to operate with a loose clamping plate.
