3 Information about the machine
3.1 Unpacking the equipment
Check the packaging and equipment carefully on delivery for any possible transport damage.
If there is any sign of damage, contact the retailer and report the damage. Report packaging
damage to the transport company as well.
Check that the delivery matches the order. If there are any questions, contact the retailer.
3.2 Transport
WARNING
Risk for personal injury and mechanical damage
NOTE
During moving, transport and lifting, the weights shall be in
position 1, see Handling Weights.
3.2.1 Transport
Always make sure that the machine is securely anchored to its surroundings and that the
grinding head is lowered on to the surface. Tighten the securing straps, or other equipment
used for anchoring during transport over non-moving parts, e.g. the machine's chassis.
3.2.2 Lifting
The machine can also be lifted using the lifting eyes provided or using other approved lifting
equipment. In which case, make sure that the weights are locked in the forward position and
that the handle is in its back position, see Handling weights page 33 and Handle setting
page 31. When lifting the machine, lifting straps must be used.
3.2.3 Movement
When moving on sloping surfaces, e.g. loading ramps, the machine should be secured in the
lifting eyes, for example, using a winch. This is a safety measure in case the machine starts
to roll out of control or tip over. The weights should be in position 1, see Handling weights
page 33. Otherwise, there is a risk that the machine tips backwards. Ensure there is no
one below the machine during movement on sloping surfaces.

3.2.4 Hanging the cover
During transport or work with HTC grouting, the cover can be hung up so it does not drag on
the surface.
Lift up the cover and secure it with the rubber straps to secure the cover in the raised
position.
WARNING
Moving parts. High noise level.
Risk for personal injury.
Always use the recommended personal protective equipment.

3.2.5 Support wheel
To ease movement, a support wheel can be firmly mounted on the machine.
The support wheel can be mounted during grinding.
3.3 Storage
The machine should be stored in a heated, dry area when not in use. It may be damaged by
condensation and cold.

3.5 Hand and arm vibrations
Hand and arm-weighted vibration levels [m/s2] for HTC DURATIQ have been measured using
equipment approved in accordance with ISO 5349-1:2001. The uncertainty of measurement
for the measuring equipment is given as ±2%.
The machine has been tested in accordance with ISO 5349-2:2001 and ISO 20643:2005 in
order to identify the operations that contribute to the most frequent vibration exposures. At
vibration levels > 2.5 m/s2the exposure time should be limited in accordance with the table
below. For vibration levels > 5 m/s2immediate measures must be taken by the employer to
ensure that the exposure time does not exceed the time specified in the table below.

4 Machine description
4.1 General machine description
A grinding machine from HTC has been developed for processing various types of floor. It is
used to grind, coarse grind, prepare and polish concrete, natural stone and terrazzo floors or
other materials specified in this manual or material recommended by HTC.
Some grinding machines can be equipped with radio control. Radio control is an accessory
that eases the work considerably.
The machine is constructed from a number of main components, see below page 20.
The handle can be set in a number of different tilt positions. Choose a position that suits you
best, when the machinery is to be operated manually.
The machine's grinding head can be equipped with one of several different grinding discs
that are covered by a sealed sloping cover against the floor. The cover together with the
connected vacuum system provide the conditions needed for a good work environment. The
cover ensures that the operator does not come into contact with rotating mechanical parts
and exposure to dust is minimised. Because the cover is floating, the dust uptake is
optimised since it is always in contact with the surface.
Always make sure that a dust extractor is connected to the grinder during dry grinding to
prevent as far as possible exposure to dust particles of operators, people in the vicinity, the
grinder and other equipment.
WARNING
Dust.
Risk for personal injury.
The dust that is sucked up may be harmful if inhaled. Follow
local regulations and use breathing protection.
The machine can be easily equipped with a large number of tools, depending on the floor
material to be ground. For more information about different tools, see HTC's website
www.htc-floorsystems.com.
Some grinding machines can be equipped with a Mist Cooler system for effective cooling of
the grinding tools. This system enables a very fine water mist to be diffused through a nozzle
over the floor surface, which cools the tools and thereby makes the grinding more effective.
