3. Machine description
3.1 General information
The machine is a dust extractor with an integrated pre-separator for industrial and building use
intended for the dry vacuuming of dust particles, e.g. concrete, wood, stone etc. The dust extractor
is equipped with a pre-separator, where the majority of the dust is collected instead of being sucked
into the actual vacuum cleaner, as well as a two-stage lter system, a coarse lter followed by a ne
lter.
It is also equipped with a lter cleaning system that unloads the vacuum cleaner's lter increasing the
service life and maintaining the performance of the dust extractor.
To handle the collected dust, a bag system is used on the pre-separator and dust extractor. To pre-
vent bags from being sucked into the pre-separator or dust extractor, they are equipped with a rubber
valve that closes during operation.
The pre-separator can be raised and lowered with a simple movement and easily removed from the
chassis if necessary.
The dust extractor can also be controlled from HTC DURATIQ grinder.

4. Transport & storage
4.1 Handling and storage
The dust extractor should be stored in a heated, dry area when not in use.
Otherwise it may be damaged by condensation and cold.
The dust extractor's dimensions and weight are given in chapter Technical data.
4.2 Transport & lifting
Warning!
If handled carelessly, the dust extractor can overturn and cause both
personal injury and damage to the equipment.
Always ensure that the dust extractor is emptied of dust and other particles before it is transported,
lifted or hoisted. When being moved with a forklift, always place the forks under the protection bar.
Always make sure that the dust extractor is securely anchored to its surroundings and that the park-
ing brake is in the locked position during transport to prevent it from moving during transport. Ensure
that the securing straps, or other equipment used for anchoring during transport, are tightened in
lashing points and tensioned downwards as illustrated.
When lifting the machine, use 4 approved lifting straps at the lifting points on the machine.
When the dust extractor is to be hoisted, it must be securely anchored at two lashing points.

5. Operation
5.1 Safety
This chapter contains all the warnings and notes that must be considered for the dust extractor.
5.2 General information
Warning!
Use protective equipment such as safety shoes, safety goggles, pro-
tective gloves, mouth mask and hearing protection.
5.3 Various positions of the pre-separator & dust extractor
Warning!
The dust extractor may only be used or repaired by personnel who
have received the requisite theoretical and practical training and who
have read the user manual.
Warning!
The dust extractor may only be used and moved on level surfaces.
There is a risk for crush injuries, if it should start to roll.
Tip!
Check the minimum recommended cable area before using an exten-
sion cord. You will nd the recommended cable area under Technical
Data.
The pre-separator and the dust extractor can be lowered during transport but can also be re-
moved with a simple movement.

5.6 Dust ltration
Note!
The valve should not be closed for more than a short interval, because the risk
of dust building up and blocking the pre-separator increases signicantly.
Hose connection
The suction system is equipped with a 3" connector
for quick, easy and safe connection of the suction
hose between the grinding machine and dust ex-
tractor or other accessories that are to be used for
dust collection.
Bypass valve
To empty the space down in the bag, close the by-
pass valve by turning counter clockwise.
Pre-separator
The task of the pre-separator is to separate the
majority of the dust from the airow that passes the
machine.
The separated dust is collected in the space under
the actual pre-separator.

16
HTC D60
www.htc-oorsystems.comV 1.0
When the valve is closed, the dust falls into
the space down into the bag and if the bag is
full, it can now be replaced. When the valve is
closed, the dust is not separated but instead
continues directly to the coarse lter contain-
er. To start separating the dust, turn the valve
back.
When the air enters the vacuum tank, the
speed reduces, so the remaining dust in the
airow falls down into the bag. The airow
then passes a coarse lter in the coarse lter
container.
Air cleaning
To achieve a high degree of cleanliness, the
air also passes a ne lter before it passes the
side duct fan and ows out through the ex-
haust.

17 www.htc-oorsystems.com
HTC D60
V 1.0
To clean the coarse lter, hold button 1 in
so that the inlet valve closes and the airow
into the coarse lter container ceases. The
side duct fan then starts to build up a greater
negative pressure.
Keep button 1 held in and then press but-
ton 2 to open the cleaning valve and clean
the coarse lter.
On the display, check that the desired
lter status is achieved after cleaning.
Otherwise, clean again.
If the lter status is above 30%,
dust is stuck in the lter and the lter
must be cleaned or replaced. See Filter

Place the bags in the holder and install on the container. Pull up the inner part of the bag and tighten
with the strap. Seal the lower part with a tie.
Tip!
Pull out a new length of empty bag down to the collection plate. This
is to create the best conditions for the waste to fall into the bag.
5.8 Replacing the dust bag
The dust extractor is equipped with a bag system that makes it possible to minimise dust exposure when
changing dust bags. This bag system can be ordered. Please contact your HTC retailer.
Warning!
Use protective equipment such as safety shoes, safety
goggles, protective gloves, mouth mask and hearing pro-
tection.
When the bag is full, pull out the bag and install two
ties and cut off the bag.

6.1 Automatic lter cleaning
Automatic lter cleaning automatically cleans the dust extractor's coarse lter when it becomes
blocked. This occurs by electromagnets connecting to buttons 1 and 2, whereupon the dust ex-
tractor's control panel can perform lter cleaning automatically or via a button push. Filter cleaning
occurs when one or more of the following conditions are met:
• Set time between lter cleans reached.
• Filter status - Standard is 100%.
Lower values giver more frequent pulses.
• Flow limit - Standard is 240 m³/h (150cfm).
Higher values give more frequent pulses.
To adjust pre-set values, see 4.9 Display information menu.
