HTC 800 RX Introduction
2.0 1
1 Introduction
1.1 General Information
HTC 800 RX (R = Radio control, X = Four grinding discs) is a grinder that can be used
to grind, strip, clean and polish concrete, natural stone and terrazzo floors. The
machine's area of application depends on the choice of tool. You can easily mount and
replace the tool, thanks to the EZchange patented tool system.
The radio control means the operator is not affected by any vibrations from the
machine. Moreover, the grinding work is more effective since, for instance, emptying
the dust extractor and handling the cables can be done at the same time as the machine
is grinding.
Read the manual carefully, so you are totally familiar with the machine before you start
to use it. Contact your local retailer for further information. For contact information, see
Contact Information at the start of the manual.
1.2 Responsibility
Even though every effort has been made to make this manual as complete and accurate
as possible, we bear no responsibility for incorrect or missing information. HTC
reserves the right to change descriptions in this manual without giving prior notice.

in any other way without the written approval of HTC.

In addition to the general functions, this manual deals with the areas of application and
the maintenance of the grinder.

it is extremely important to read and understand the text next to these symbols
particularly carefully. There are other symbols indicating practical tips. These are to
help you use the machine in the easiest and most effective way.
The following symbols are used in the document to indicate where special attention is
needed.

1.4 Transportation
Note!
The machine cannot be moved manually if the drive wheels are locked and the
radio control activated.
Warning!
Never deactivate the radio control function when you have stopped the machine
on a sloping surface during loading, since the machine can start to roll.
Always make sure that the grinder is securely anchored to its surroundings and the
grinding head is lowered against the surface.. Make sure that the securing straps or other
equipment used for anchoring during transport are tightened over non-moving parts, e.g.
the grinder's chassis.
The machine can also be transported with other lifting equipment, for example truck or
crane, using the lifting eyes provided, position 4, Figure3-1, page10. In which case,
make sure that the weights are locked in the forward position and that the handle is in its
back position, seeFigure4-6, page20andFigure4-2, page17.
When lifting the grinder, lifting straps must be used. These must be attached
well-secured in the lifting eyes provided, position 4, Figure3-1, page10. Only use
lifting straps approved for lifting equipment.
HTC 800 RX Introduction
2.0 3
The machine can also be moved short distances using the inbuilt battery drive and with
the support wheel fitted. The battery capacity is sufficient to transport the machine for
ca. 30 minutes.
Do not transport the grinder on sloping surfaces, e.g. loading ramps, without securing it
by the lifting eyes, , position 4, Figure3-1, page10for example with a winch. This is
a safety measure in case the grinder starts to roll out of control. Also make sure that
people (including operator) in the vicinity are at a safe distance in order to prevent
personal injury, in the event that the grinder starts to roll out of control.

uncertainty 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/s², the exposure time should be limited in
accordance with the table below. For vibration levels > 5 m/s², immediate 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

Note!
The machine must only be lifted using the lifting eye intended for the purpose
in accordance with the relevant instructions.
Note!
The machine should be stored in a dry, warm (plus degrees) location when not
in use.
Note!
If the machine is stored in a cold area (below zero), it must be kept in a warm
area (above zero) for at least two hours before use.
Note!
When dry grinding, a suitable dust extractor should be used. For available
models of dust extractors, go to HTC's website www.htc-floorsystems.com for
more information.
Note!
The dust extractor's suction hose must be connected to the appropriate socket
on the machine. Adjust the dust extractor to match the grinder's capacity.
Note!
Do not use the emergency stop switch to stop the machine, except in
emergencies.
Note!
As long as the emergency stop switch is pressed in, the machine cannot be
started. Reset by turning the switch 45° clockwise so that it pops out again. The
machine can then be restarted.
Note!
After removing glue and wet grinding, always lift up the grinding heads so that
they do not stick to the floor and damage machine components and the floor
when restarting.
Note!
When wet grinding, the water tank must be filled with water. Only use cold
water with no chemical additives.
