Discotom-2
Instruction Manual

Discotom-2 should be placed on a sturdy table, such as the Struers
laboratory cabinet, this accommodates recirculation unit, cut-off
wheels, tools, etc.
Place Discotom-2 on the 4 rubber mounting pads supplied with the
machine (one in each corner). The pads serve to dampen the noise
and, in addition, provide adequate ventilation of the motor. Mount the
sieve and water guide plate as shown in fig. 13. Fit the thin hose (the
feed hose) between the outlet branch of the pump and the inlet
branch of Discotom-2. Use hose clips. Take the return hose from the
outlet branch of Discotom-2 to the inlet branch on the lid. The elbow
pipe supplied with the machine may be inserted in the return hose to
assist bending. Hose clips may be used, they should only be slightly
tightened.
In Discotom-2 the two units can be made to start simultaneously.
This is effected by connecting the pump motor to the free terminal
screws in the connection box at the rear of Discotom-2 (use the
upper cable entry fig. 3/see mains circuit diagram).
Before connecting Discotom-2 to the recirculation unit, check that the
voltage and frequency stated on the type plates correspond to the
local voltage and frequency.
Fig. 3 also illustrates how to connect Discotom-2 through the lower
cable entry (see mains circuit diagram). When looked at from the left,
the cut-off wheel should rotate clockwise.
The pump should rotate in the direction indicated by the arrow. The
rotational directions are reversed by changing over two phases.
Green/yellow is earth.

It is important to provide effective cooling during the cutting of
metallographic specimens.
The best coolant is water to which an additive is added to avoid
corrosion. Therefore always operate the Discotom-2 with a
recirculation cooling unit. Discotom-2 is supplied with a bottle of
additive containing both a corrosion inhibitor and a wetting agent, a
quantity of which should be added to the cooling water according to
the directions on the label. Emulsified oils may also be used and will
provide good protection, but as these oils greatly reduce the cooling
effect, we strongly recommend the use of Struers "Additive for
Cooling Fluid".
