HTC GL 40 D Introduction
2.0 1
1 Introduction
1.1 General Information
The HTC GL 40 D (Greyline 40 Dust extractor) is a dust extractor that is best used
together with HTC's smaller grinding machines in connection with dry grinding of stone
and concrete floors, and in accordance with HTC's recommendations. The HTC GL 40
D is constructed with sock filter and absolute filter. The dust sucked up is collected in a
bag under the dust extractor.
Read the manual carefully so that you know how to use and maintain the dust extractor
before using 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.
This manual is protected by the Copyright Act and no part of it may be copied or used
in any other way without the written approval of HTC.
1.3 Manual
In addition to the general functions, this manual deals with the areas of application and
the maintenance of the machine.
1.3.1 Safety Instructions – Explanation of Symbols
A number of symbols are used in the manual to highlight the most important sections,
see below. It is important that you carefully read through the descriptions of the symbols
in order to avoid the risk of both material damage and personal injury. 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.
Warning!
This symbol means Warning! and indicates a risk of personal injury or material
damage in the event of incorrect use of the machine. If you see this symbol next
to a section of text, you must pay particular attention when reading through the
text and not carry out any operations of which you are unsure. This is for your
own and other users’ safety and to avoid damage to the machine.

Introduction HTC GL 40 D

Note!
This symbol means Note! and indicates a potential risk of material damage in
the event of incorrect use of the machine. If you see this symbol next to a
section of text, you must pay particular attention when reading through the text
and not carry out any operations of which you are unsure. This is to avoid
damage to the machine.
Tip!
This symbol means Tips! and implies the inclusion of tips and advice on
effective use of the machine or ways of reducing wear and tear to the machine.
If you see this symbol next to a text, you should read through the text to make
your work easier and to extend the service life of the machine.
1.4 Transportation
Always ensure that the machine is emptied of dust and other particles before it is
transported, lifted or hoisted.
Always make sure that the machine is securely anchored to its surrounding during
transport to prevent it from coming into motion. Make sure that securing straps or other
equipment used for anchoring during transport are tightened over non-moving parts, e.g.
the machine's chassis.
When lifting the machine, do so according to chapter Lifting the machine, page14.
Do not transport the machine on steep sloping surfaces, e.g. loading ramps, without
securing it properly, for example with a winch. This is a safety measure in case the
machine 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
machine starts to roll out of control.
When the machine is to be hoisted, it must be securely anchored in the notches for
secure lifting (position 4 Figure3-2, page9), which are found on both of the chassis'
long sides. To prevent the machine from tipping, make sure to pull with equal force so
the machine does not twist askew and end up on its side.
The swivelling wheel must be pointing forwards in the direction of travel.
1.5 On delivery
The following items are included in the delivery. Contact your retailer if anything is
missing.

cylinder sections tips against the handle.
2.3 Notes
Note!
The dust extractor is best used together with HTC's grinding machines in
connection with dry grinding of stone and concrete floors, and in accordance
with HTC's recommendations.
Note!
Never use a dust extractor in connection with wet grinding, as it may cause
blockages in the dust extractor's suction hose and damage the sock filter,
absolute filter and side duct fan.
Note!
Only use original spare parts from HTC for the dust extractor. Otherwise,
neither the CE marking nor the warranty will be valid.

HTC GL 40 D Safety
2.0 7
Note!
For the CE marking to be valid, the instructions in this manual must be
followed.
Note!
The dust extractor should be stored in a dry, warm (above zero) location when
not in use.
Note!
If the dust extractor is stored in a cold location (below zero), it must be placed
in a warm location (above zero) for at least two hours before use.
Note!
Discolouration on the top of the absolute filter indicates that the sock filter is
not functioning as it should. If the absolute filter is dirty on the underside, the
filter is broken.
Note!
The absolute filter holder must be removed before the dust extractor can be
lowered to the service position, since the hose between the upper cylinder
section and the absolute filter holder will otherwise make this impossible.
Note!
When checking the absolute filter, the dust extractor must be placed in the
operating position.
