Safety Precaution Sheet
To be read carefully
before use
1. The operator(s) should be fully instructed in the use of the machine and its cut-
off wheels according to the Instruction Manual and the instructions for the cut-
off wheels.
2. The machine must be placed on a safe and stable support table. All safety
functions and guards of the machine must be in working order.
3. The unit must be installed in compliance with local safety regulations
4. Use only intact cut-off wheels. The cut-off wheels must be approved for min. 50
m/s.
5. Observe the current safety regulations for handling, mixing, filling, emptying and
disposal of the additive for cooling fluid.
6. The workpiece must be securely fixed in the quick-clamping device or the like.
Large or sharp workpieces must be handled in a safe way.
7. Do not touch anything inside the cutting chamber while positioning the cut-off
wheel with the position button.
8. Struers recommends the use of an exhaust system as the materials to be cut
may emit harmful gasses or dust.
9. The machine emits only moderate noise. However, the cutting process itself
may emit noise, depending on the nature of the workpiece. In such cases, use
of hearing protection is recommended.
10. The machine must be disconnected from the mains prior to any service.
11. Use of working gloves is recommended as workpieces may be both very hot
and produce sharp edges.
If optional rubber curtains are needed in order to cut long, protruding workpieces:
1. Check with your local authorities whether rubber curtains are approved as
protection in your country.
2. Do not put hands through the rubber curtain during operation of the machine.
3. Protruding workpieces should be shielded or marked.
The equipment is designed for use with consumables supplied by Struers. If subjected to misuse, improper
installation, alteration, neglect, accident or improper repair, Struers will accept no responsibility for
damage(s) to the user or the equipment.
Dismantling of any part of the equipment, during service or repair, should always be performed by a qualified
technician (electromechanical, electronic, mechanical, pneumatic, etc.).

1. Getting Started
In the packing box you should find the following parts:
1 Fork spanner 30 mm, for changing the cut-off wheel
1 Grease gun, for lubrication of tilting frame bearings and
oscillating table.
2 Cover plugs for threads for cutting tables
1 Set of Instruction Manuals
1 PVC hose 1/2", 2 m
1 Outlet hose, 2 m
1 Drain elbow pipe, 15°
5 Hose clamps
The kit also contains the below parts exclusively for Unitom-2/-5
1 38 mm drain hose
1 87° elbow drain fitting
1 32-50 mm hose clamp
Unitom-50 should be placed on the optional Struers table
(LABUL), or a table that is able to carry a weight of min. 200 kg.
Adjust the table height using the screws in the table legs. It is
important that both the table and Unitom-50 are level. Place
Unitom-50 on the table. If the machine is not level, adjust the
height for each corner, as follows:
Loosen the upper 13 mm nut under the corner screw.
Adjust the lower 8 mm nut with a spanner.
Re-fasten the upper 13 mm nut again.
Repeat the adjustment for each of the other three corners until
Unitom-50 is levelled.
A 65 mm hole must be drilled in the base of the table for
attachment of the outlet hose.
(see drawing 15317049 in the Spare Parts manual).

The cooling pump is delivered wrapped in corrugated cardboard
and placed inside the cutting chamber. The pump is connected as
follows:
Remove the cooling pump from its wrapping.
Mount the inlet hose on the pump using a hose clamp.
Mount the other end of the inlet hose on the back of Unitom-50
using a hose clamp.
Lead the pump through the opening in the back of the table.
Mount the drain elbow pipe on the water outlet tube in the
hose box at the bottom of Unitom-50.
Mount the outlet hose with the hose clamp on the drain elbow
pipe. Adjust the length of the hose, so as to direct the water
into the recirculation tank.
Place the tank on the trolley.
Place a disposable plastic insert (EXOSP, ordered separately)
in the tank and fold it over the edge.
Fill the tank with 63 l of water and 2 l Struers Additive for
cooling fluid. The water level should be 8-10 cm below the
upper edge of the tank.
Connecting the
Recirculation Unit
IMPORTANT
A too high level of coolant in the tank might damage the pump. To avoid
this: place the disposable insert so that the pre-punched hole is in front of
the overflow aperture in the tank.
Always maintain the correct concentration of Struers Additive in the cooling
water (percentage stated on the container of the Additive). Remember to
add Struers Additive for cooling fluid each time you refill with water.
