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.
Identified work conditions Measured values [m/s2]Daily permitted exposure
(number of hours)
Grinding/polishing < 2.5 m/s2> 10 h
3.6 Sound power level
This machine has been tested for noise in accordance with ISO 11202.
Measured using class 1 instruments as sound level meters. For information about sound level
power, see chapter Technical Data page 56.

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 as recommended by HTC.
The machine is constructed from a number of main components, see below.
The handle can be set in several different positions.
The machine's grinding head is covered by a sloping hood, which provides a close fit to 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.
