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. Use only intact cut-off wheels. The cut-off wheels must be approved for
min. 50 m/s.
4. Observe the current safety regulations for handling, mixing, filling,
emptying and disposal of the additive for cooling fluid.
5. 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.
6. The cutting handle should be lowered slowly and carefully, in order to
avoid breaking the cut-off wheel. The cutting handle automatically
returns to its top position when you let go the handle.
7. Struers recommends the use of exhaustion as the materials to be cut
may emit harmful gasses or dust.
8. Use of working gloves is recommended as workpieces may be both
very hot and produce sharp edges.
9. Use of safety shoes is recommended when handling large or heavy
workpieces.
10. Use of safety goggles is recommended when using the flushing hose.
The equipment should only be used for its intended purpose and as detailed in the Instruction Manual.
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

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
2 Cover plugs for threads for cutting tables
1 Drain angle, 450
1 Drain angle, 900
1 Outlet hose 2 m
for connection to external cooling unit
2 Hose clamps, 35-60 mm
1 Set of Instruction Manuals
 Remove the wooden block holding the spindle using a 17 mm
spanner.
 Insert the two cover plugs delivered with the machine in the
threaded holes.
Unitom-2 should be placed on the optional Struers Table Unit, or a
table which 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 the table and Unitom-2 are level. Place Unitom-2 on
the table. If the machine is not horizontal, you must 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.
 Fasten the upper 13 mm nut again.
 Repeat the adjustment for each of the other three corners until
Unitom-2 is levelled.

To ensure optimal cooling, Unitom can be fitted with a Cooli unit. The
Cooling System 5 is a Cooli configuration designed for use with
Unitom.
To connect the Unitom to a cooling unit:
 Plug the Cooli control unit’s communication cable into the
Unitom’s control socket.
 Connect the quick coupling on the Unitom’s cooling fluid inlet
tube to the cooling unit’s pump outlet (A).
 Insert the drain pipe  in the water outlet on the back of
Unitom-2 and mount the 90° elbow pipe . Lubricate the sealing
ring with grease or soap to facilitate insertion. (Use the other
elbow pipe if more suitable).
 Strip the steel spring from approx. 3 cm of the outlet hose and
cut. Bend the cut end towards the centre of the hose. Mount the
outlet hose  onto the elbow pipe and clamp the stripped
section using a hose clamp.
 Check that the outlet hose slopes downwards when connected. If
necessary adjust the length of the hose.
 Insert the open end of the hose into mounting hole in the bracket
on top of the Cooli filter unit (B).
 Connect the cooling unit to the mains power supply.
Connecting a Cooli
Cooling Unit
Note:
Cooling System 5 includes a static filter.
For intensive use, and for materials generating a lot of swarf,
a bandfilter is recommended.
Note
Before connecting the cooling unit to the Unitom,
follow the instructions in the Cooli Instruction Manual
to prepare it for use.
IMPORTANT
Before connecting, check that the mains voltage corresponds to the voltage
stated on the type plate on the side of the machine.
