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. See Securing the load, page15.
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 has to be secured in the chassis's lifting points (see
position 4 Figure3-1, page7). 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.

Machine description HTC GL PS
6 1.0
3 Machine description
3.1 General Information
HTC GL PS is a cyclone type pre-separator for industrial and building use intended for
the dry vacuuming of dust particles, e.g. concrete, wood, stone etc. The pre-separator is
equipped with a 3" Camlock connector for quick, easy and safe connection of the
suction hoses between the grinding machine and dust extractor or other accessories that
are to be used for dust collection.
The pre-separator's function is to capture the majority of the dust instead of allowing it
to be sucked into the dust extractor. As a result, the dust extractor's filter is relieved. The
filter has a longer service life and a higher performance is maintained, resulting in more
effective dust collection for the grinding machine. For handling the collected dust, a
Longopac sack system is used.
The separated dust is collected in the volume under the pre-separator, where it can be
emptied by dropping it into the Longopac by closing the bypass valve (Position
1Figure3-1, page7) or turning off the dust extractor.
To prevent the Longopac from being sucked into the pre-separator, it is equipped with a
pair of dust covers that close during operation. These sit in the bottom on a level with
the Longopac holder (pos 9 Figure3-1, page7).
The pre-separator is equipped with a bypass valve (Pos 1 Figure3-1, page7). This
valve makes it possible to use the dust extractor even during replacement of the
Longopac on the pre-separator(Replacing Longopac during operation, page12).

3.2 Function
The pre-separator is connected, with the help of hoses, between the grinder and the dust
extractor. The airflow coming from the grinder and into the pre-separator is saturated
with dust. The cyclone forces the air to rotate and release a large amount of the dust,
down into the collection volume above the Longopac bag. The air then continues to the
dust extractor where the remaining dust is filtered out. See Figure3-2, page8.
If the Longopac needs to be replaced during operation, the bypass valve is closed. When
the bypass valve is closed, the connection between the pre-separator's cyclone and the
volume that stores the dust before it ends up in the Longopac is blocked. It will not then

be possible to separate the dust with the pre-separator; instead it continues directly into
the dust extractor.
When the valve is closed, there is normal pressure in the volume for the pre-separator's
dust collection and the dust that has collected falls down into the Longopac. Should the
Longopac be full of dust, it can now be replaced. If it is not full, the valve can be slid
back.
