Product overview
Safety Instructions
Warning
Cutting, especially when DRY cutting, generates dust that comes from the material being cut, which
frequently contains silica. Silica is a basic component of sand, quartz, brick clay, granite and numerous other
minerals and rocks. Exposure to excessive amount of such dust can cause:
•Respiratory disease (affecting your ability to breath), including chronic bronchitis, silicosis and
pulmonary fibrosis from exposure to silica. These diseases may be fatal!
•Skin irritation and rash.
•Cancer according to NTP* and IARC*
*/ National Toxicology Program, International Agency for Research on Cancer
Take precautionary steps:
•Avoid inhalation of and skin contact with dust, mist and fumes.
•Wear and ensure that all bystanders wear appropriate respiratory protection such as dust masks
designed to filter out microscopic particles. (See OSHA 29 CFR Part 1910.1200)
•Wet cut when feasible, to minimize dust.
Warning
•Fuel and fuel fumes are highly inflammable and can cause serious injury when inhaled or allowed to
come in contact with the skin. For this reason observe caution when handling fuel and make sure there is
adequate ventilation.
•The exhaust fumes from the engine are hot and may contain sparks which can start a fire. Never start the
machine indoors or near combustible material!
•Do not smoke and do not place any hot objects in the vicinity of fuel
Warning
•Long-term exposure to noise can result in permanent hearing impairment. Always use approved hearing
protection. Listen for warning signals or shouts when you are wearing hearing protection. Always
remove your hearing protection as soon as the engine stops.

Handling
Warning
•Running an engine in a confined or badly ventilated area can result in death due to asphyxiation or
carbon monoxide poisoning.
•Outdoor use or in well ventilated areas only.
Warning
•Make sure the assembly area is firm, so the dust extractor does not tip over. Risk of personal and
material injury.
Warning
•Risk of pinching when handling the toggle fastener.
Warning
•The machine must not be used in environments where explosive gases may be present. Serious risk of
explosion.
•Sparks may appear and start a fire when you work with the machine. Always keep fire fighting
equipment handy.
Explanation of symbols
Transportation
Caution
•During transportation, battery and propane tank must be securely fastened and completely disconnected
at all times.
Caution
•Before operating the vac after transportation, propane tank and battery must be re-connected and
correctly assembled.
1. Battery: Make sure that the wires are firmly connected to the correct terminals (black (-) &
Red (+). Also confirm that the bracket that holds the battery in place is correctly assembled, so
that the battery can’t move during operation.
2. Propane tank: Make sure that the tank is firmly held in place by the ex-centric locks and holder
plate where the propane tank sits on the back of the vac. It should not be able to move when
correctly assembled.
WARNING
Before cleaning and servicing the machine, you must turn the machine off and disconnect battery and
propane tank
ATTENTION!
Wait until fan impeller has completely stopped before starting servicing the machine.
The exhaust will get very hot after running the engine for just a short time

•Avoid cleaning with a high pressure cleaner. If necessary, do not direct at the openings on the machine,
especially the opening for the cooling air.
•Before moving the machine from the working area, the machine must be cleaned. Furthermore, the inlet
must be locked using the inlet valve.
•All other equipment must be considered to be contaminated and be treated thereafter.
•If possible, use a special suitable room.
•Proper personnel protective equipment must be used.
•After a service, all parts that are contaminated must be taken care of properly in plastic bags, according to
all regulations.
•If the vacuum cleaner has to be used for other purposes, it is extremely important that the vacuum cleaner is
cleaned to avoid the spread of hazardous dust.
•Correct distance between clutch plates = 0,5 mm (-0,2 + 0,3)
Warning
•Dust can be spread when the coarse filter and the absolute filter are replaced that can be dangerous to
health. Accordingly, the user should wear protective glasses, protective gloves, and a breathing mask
conforming to protection class FFP3.
Warning
•Do not puncture the absolute filter. Risk of dust dispersion.

Function
The machine is used for sucking and separating dry, non-combustible dust with an explosion limit value of
>0.1mg/m3.
The engine is started by the key switch. When the engine has warmed up and is running at idle, the clutch is
engaged by a second switch. Dust laden air is then sucked through the inlet valve at high speed via the suction
hose. The air is slowed down by the cyclone and coarse dust particles are separated out, partly by centrifugal
force and partly by gravity. Air and finer particles then pass through the tube filter where separation takes place.
The machine is designed for filter cleaning by reverse air pulse.
The separated dust accumulates in the cyclone until the machine is switched off, when it drops through the
bottom flap into the plastic bag.
Use
Before use, the user must be trained in the handling of the dust extractor and the hazardous dust.
The filter must be cleaned from time to time. This must be done before changing the plastic bag. It can also be
done when the work is complete or when there is poor suction.
Procedure: While running the machine, seal the inlet using the inlet valve. Let the machine build up vacuum for
a few seconds (approx. 5 sec.) then quickly push down on the top handle and release it slowly. Repeat this
procedure 5 times. If suction remains poor, the filter should be replaced. The plastic bag may only be replaced
after cleaning the filter.
The plastic bag must be tied up after removal. Only use original parts.
Warning
Before starting the machine, check that the inlet valve is open and that the clutch is disengaged
Warning
Before starting the engine, check the service table for daily maintenance

Filter change
Risk of dust dispersion - Use of personal safety equipment
Unhealthy dust can be spread during filter change. Accordingly, the user should wear protective glasses,
protective gloves, and a breathing mask conforming to protection class FFP3.
Main filter
Loosen the two latches between the tank and the lower cyclone. Loosen the two latches at the hose connection
between the tank and the absolute filter cover. Rotate the tank forwards. Rotate the filter plate counter
clockwise 10 degrees and carefully turn filter and holder upside down. Place a plastic bag over the filter unit.
Lift the filter carefully and pinch up the bag by hand and then tie the bag up. This bag must be properly disposed
of.
Insert a new complete filter pack in reverse order. Only original filters may be used.
HEPA filter
Loosen the three latches holding the filter cover and carefully lift the filter up and into a plastic bag. This bag
must be properly disposed of. Insert new filters in reverse order.
Recommended intervals for filter change: Socks filter every 6 months and Hepa filter every 12 month.
Muffler
The muffler gets very hot during and after use. This also applies during idling. Be aware of the fire hazard,
especially when working near flammable substances and/or vapours. The muffler is designed to keep noise
levels to a minimum and to direct exhaust fumes away from the user.
Inspecting the muffler
• Check regularly that the muffler is complete and secured correctly.

Warranty
All Husqvarna devices and accessories have a 24-month factory warranty for material and manufacturing
defects. Do not attempt to repair the suction apparatus without the consent of the manufacturer.
The warranty does not cover defects which are the result of normal wear and tear, negligence, defective use,
unauthorised repair or the suction apparatus being connected to the incorrect voltage.
In the event of any complaint, the suction apparatus or an agreed part of it must be returned to us or our
authorised representative for warranty examination and for any warranty repair or replacement.
WARNING: Never use a machine without a muffler, or with a faulty muffler. A
damaged muffler may substantially increase the noise level and the fire hazard.
Keep fire fighting equipment handy.
WARNING: Turn off the engine and wait for the fan to completely stop before opening
the machine to change filters.
The exhaust will get very hot after running the engine for just a short time
