6. Danger zone
7. General description of the product
7.1. Description of the use
(zone of increased risk of injury)
• The entire inside area of the device. Keep hands, hair, clothing and tools away from
the mechanism while it is in use.
The machine is primarily used to knead or condition polymer clay. The material is inserted
between the rollers and extruded/compressed by turning the crank. When the material
has passed through the mechanism, it can be folded in half and inserted again between
the rollers. This procedure is repeated until the material is su󱐰ciently conditioned and supple.
Once the material is conditioned, you can alter its thickness by adjusting the o󱐯set between
the rollers.

9
Mixing polymer clay of di󱐯erent colors (‘blending technique’) represents another use
of the device. Fore more information on this technique, see the links at the end of the document.
7.2. Technical description
This polymer clay kneader consists of the actual mechanism, legs and a base plate and
has three gears with teeth placed at a constant distance from the centre. The gears are
xed to the device’s frame. The drive gear meshes with a pinion (a small gear) providing
a gear ratio of 2:1, thereby reducing the force needed. The mechanism is also equipped
with an Oldham coupling which is located between the drive gear and the sliding roller
shaft. This coupling allows a smooth adjustment of the o󱐯set between the rollers. With this
system, the o󱐯set, or opening, between the rollers can be varied from 0 to 6 mm (E6 model)
and between 0 and 12 mm (E12 and M12 models).
The rollers have two U-shaped cleaner/scraper blades at the bottom attached to the frame
with two bolts. This ensures an easy operation and cleaning (loosen the two bolts and
remove the cleaner/scraper blade for cleaning).
The device is designed for manual operation using a crank which is attached to the rollers
with a 2:1 speed reducer. This makes it easy to knead solid and thick blocks of polymer clay.
Optionally, the machine can be tted with a hexagonal shaft adapter to which a cordless drill
can be connected via a speed reducer (see the relevant chapter for guidelines for using the
device with a connected cordless drill).
The machine can be secured to a table with a carpenter clamp or any C-clamp, which
is not included. The machine is equipped with magnets and sheet metal rest pads. The
rest pads can be placed freely and stuck to the table (observing the prescribed pitch) using
a double-sided tape (supplied together with the rest pads). This system (magnet + sheet
metal rest pads) makes for a very simple way of securing the machine on a table. To disengage
the machine from the table, just push it lightly away from you or move the magnets together
away from the rest pads to break the magnetic grip holding the machine rmly on the rest
pads. Further rest pads can be stuck at various locations to create an ergonomic arrangement
on your work table that reects your needs (spare rest pads may be purchased).
The C (Constrictor) model is also equipped with telescopic rails. Using this system, you can
slide the machine out or in above/under the desk, further saving space on the table.
The E and M models di󱐯er in the height of the mechanism/leg and the length of the rollers
which dene the overall dimensions of the machine.
Optionally, the M model can be equipped with a slicer designed to cut polymer clay

10
(‘LC Slicer’). The LC Slicer is attached to one side of the leg. Moreover, the product is supplied
with a base plate for the LC Slicer’s work table, with which it can be attached to the base
of the device.
If an LC Slicer is purchased with the M model, you should follow the instructions that come
with the product when using the LC Slicer (or watch youtube video).
The space under the legs on the mechanism is large enough for storage.

8. Assembly and disassembly of the device/mechanism
8.1. Mounting the legs
Model E – Elephant: Mount the legs (items 5 and 6) to the mechanism according to Fig.2.
Secure the legs with the 12 bolts (item 7) provided to the mechanism (specically
to the hexagonal holders, item 4). The next steps are the same as for the Mammoth model.

Model M – Mammoth: Secure the provided hexagonal bolts (item 3) in the hexagonal
holders (12pcs) on the mechanism (item 4) and then attach the legs (items 5 and 6)
to the mechanism according to Fig.3.
Fig.3 Attaching the legs to the Mammoth model

15
Secure the attached legs with the 12 bolts (item 7) provided to the mechanism - Fig.4.
In the last step, place the mechanism with the legs onto the base plate (item 9) and secure
it with 8 bolts (item 7) to the nuts in the base plate - Fig.5.
Fig.4 Attaching the legs with bolts Fig.5 Mounting the base plate
8.2. Attaching the adhesive rest pads on the work table (magnetic version)
Attach the sheet metal magnetic pads with self-stick tape to the table (see Fig.1).
Alternatively, you can secure the rest pads to the table with small screws (the tabletop will
be irreversibly damaged, so this is done at your own responsibility). It is important that you
observe the o󱐯set between the rest pads – refer to the diagram (Fig.6). You can decorate
the rest pads with the LC Tools sticker provided or your own sticker which matches the color
of the table. The base of the machine contains 4 special strong magnets allowing the device
to be snapped onto the rest pads just installed on the table.

Fig.6 This diagram depicts the o󱐯set between the centers of the magnets/rest pads
for E – Elephant (top) and M – Mammoth (bottom) as measured in mm.
Another option is to embed the magnets into the top of the table (bore a 25mm hole) and
bolt/stick the magnetic rest pads to the base of the LC Machine. The principle is the same.
The magnets can then be used to secure other tools as well. It is important that you choose
the right size and length of bolts. This is done at your own responsibility; LC Tools accepts
no liability.

8.3. Installation of the cleaner blades (Fig.7)
Attach both blades (items 20 and 21) to the rollers - item 20 (A) to the moving roller and item
21(B) to the xed roller. Secure both blades with the bolts (item 8) by screwing them into
the designated holes. The bolts must be properly tightened to ensure su󱐰cient contact
between the blade and the roller for optimal cleaning e󱐯ect.
Blades are not symmetrical see and cannot be interchanged - blade A and blade B (see Fig.8).

8.4. Installation of the crank (Fig.9)
Your device may be powered manually by you through the use of a crank. First, screw
two M8 nuts (item 11) onto the pivot arm of the drive, and then screw on the crank (item
10). Tighten the nut closest to the crank using the key tool that is provided in your kit.
Next, tighten the nut closest to the device. Tighten it so it is secure against the rst nut.
This procedure ensures that the crank will not loosen and fall o󱐯 during operation.
Fig.9 Installation of the crank for manual operation
8.5. Installation of the hexagonal shaft adapter (Fig.10)
In the event that you want to use a cordless power drill instead of the manual crank to drive
your device, you will install a hexagonal shaft adapter instead of the crank. If the crank
is installed, remove it before proceeding.
Screw two M8 nuts (item 11) onto the pivot arm of the drive, and then screw on the
hexagonal shaft adapter (item 12) after them. Tighten the nut closest to the hexagonal shaft
adapter with the key tool in your kit. Ensure that it is rmly against the hexagonal shaft
adapter. Tighten the second nut so it is secure against the rst.
This procedure ensures that the hexagonal shaft adapter will not loosen and fall o󱐯 during
the operation.

8.6. Mounting the support bolts
Connect on the support bolts (item 7) in the designated holes. Do this only after you have
mounted the machine’s legs. Before securing the screws, apply LC Lubricant to ensure
an easier tightening and longer life. Repeat as needed during use.
Fig.11 Mounting the support bolts
8.7. Mounting and dismounting the machine’s covers
The covers protect the machine from dust and ensure your safety and comfort.
We recommend that you do not remove the covers, and contact the service department
if any repairs are needed.
