LIFA Hydmaster 40 brushing machine
Congratulations on your new LIFA Hydmaster 40 brushing machine!
LIFA Hydmaster 40 is an electrically operated hydraulic cleaning machine for demanding cleaning
tasks in round and rectangular ventilation ducts. This brushing machine is designed for the brushing
of medium and large ducts where exceptionally powerful force is required.
Hydmaster 40 can also be used in kitchen grease duct and industrial pipe line cleaning. The length
of the cleaning shaft is 40 meters (131 ft.) or so it can be used in cleaning up to 75 m (246 ft.) of
ventilation duct when accessed from the access door into both directions.
The hydraulic motor provides a notably more silent alternative to pneumatically operated machines
that need compressors to work. The brush of Hydmaster 40 rotates in both directions. The rotation
direction and speed is controlled with a foot pedal.
•For demanding cleaning of medium and large (Ø400 –1200 mm (16-47”) ventilation ducts.
•Operation radius 75 meters (246 ft.)
•Rotating speed can be adjusted continuously up to 880 rpm
•Mechanically directed rotating direction to clockwise and counter clockwise.
•The brushed off debris is removed by sucking it to a negative air vacuum, such as a LIFA
HepaClean 1100, 2500, 4000 or LIFA AirClean 3500 negative air machine unit (accessory).

3
Acentering device for the brush is available as an accessory for the Hydmaster brushing machine.
The centering device helps to push the brush in the duct and centres the brush in the duct so
that no part of the duct will remain un-brushed. The use of the centering device is recommended
especially in >400 mm (16”) and rectangular ducts.
Safety Precautions
The following safety directions must be carefully observed to avoid injury to personnel or damage to
the environment or to the LIFA Hydmaster 40 brushing machine itself. Following these instructions
will ensure the safe and uninterrupted use of the machine.
•The equipment must not be positioned or use in places where there is a risk of explosion or
hazardous substances.
•The equipment must not get wet and it must be protected from moisture, vibration and wind.
•Foreign objects must not be inserted or fitted into the equipment.
•The machine cannot be covered during the use
•The user must ensure that the appliance is adjusted for the task and that the statutory
requirements are met.
1. Avoid contamination of the environment
The machine must be kept as clean as possible. The shaft must be cleaned before pushing it back
to the machine. The brushes and the shell of the cleaning shaft must be cleaned after the work has
been completed, before transporting the machine to another location.
2. General safety
The power must be switched off and the power cable unplugged when the machine is not being
used. It is forbidden to make any modifications to the brushing machine or the accessories (for
example brushes).
3. Operator safety
The person/persons performing the work must use personal protective equipment: respirator,
helmet, earmuffs, goggles, overall, protection shoes and other necessary protective equipment that
the task at hand requires.
LIFA Hydmaster 40 brushing machine has a strong rotating force. Clothes or hair can easily get
caught in the brush and cause damage or accidents. The brush must always be placed in the
ventilation duct before switching on the machine. The machine cannot be used when the brush
is outside the ventilation duct. Because of the great rotating force, Hydmaster 40 is recommended
to be used by two persons. One person directs the shaft into the duct while the other person
feeds/draws the shaft and controls the rotating of the brush.

4
4. Workplace conditions
Make sure that the lighting, air conditioning, ladder and trestle are sufficient. If the brush generates
static electricity or sparks in the duct do not use these types of brushes in the duct if there is any
flammable liquids / gases, dust or other sensitive substances nearby. Use antistatic brushes and
safety grounding and by following the special instructions in difficult conditions. Permitted operating
temperature is 5 –50 °C (41 –122 °F).
5. The cleaning shaft
Check the condition of the cleaning shaft before every use. Be careful not to damage the shaft. If the
shaft has been damaged take immediate contact to your local distributor. Minor scratches on the
shaft surface can be fixed by coating it again with a heat shrinkable tube. During storage and
transportation, the cleaned shaft must always be reeled into the drum.
6. Noise level
The sound level of LIFA Hydmaster is low (<70 dB) and it is not dependant of the operating
environment.
7. Transportation and operating position
During the transportation, the machine must be tied firmly to prevent any damage to the machine or
people. Before use make sure that all the components are in place and that the machine functions
well. The machine must be transported, used and stored in an upright position. The machine must
be positioned far enough from walls and other obstacles and placed firmly and straight. Ensure a
free rotation of the brush.
General Directions
1. LIFA Hydmaster 40 can only be used for the purposes that it is designed for and which are
outlined in the instructions. It is forbidden to use the equipment for any other purposes without
written permission from the manufacturer. If this equipment is used for a purpose other than in
which it is designed for, the manufacturer does not take responsibility for any consequences.
2. Persons responsible for operating this equipment / supervising the use of this equipment must
get acquainted with the structure, functions and the safe use of the equipment.
3. It is prohibited to remove or disable any technical protective / safety device while using the
machine.
4. If the machine has to be installed in a way that protective / safety device is disabled or device
functioning is limited, work supervisor / person in charge must immediately be notified of this.
5. Due to the nature of HVAC cleaning (done in intervals, team changing positions etc.), exposure
to vibrations (hands only) is well below all defined levels.

5
Construction and Control

1. Main switch
2. Power on indicator LED
3. Emergency stop switch
4. Pneumatic pedal - the change of the rotating and operating direction
5. Control of the rotating speed
6. Oil pressure meter
7. Oil level meter
8. Tool box

6
Operating Principles
Before beginning the work, check the ductwork with
a) LIFA Duct Control (accessory) camera inspection equipment and choose the suitable
b) brushes and other accessories based on the size and construction of the duct as well as the
composition of the removable dirt.
c) Place the machine in a firm position so that the shaft can be put directly inside the duct
d) Ensure enough low pressure in the channel network by using LIFA HepaClean or AirClean
negative pressure unit (NPU).
Before beginning the work, check the ductwork with LIFA Duct Control (accessory) camera
inspection equipment. There may be air volume controllers, noise silencers, fire dampers etc. that
can be damaged during the work.
•In large rectangular ducts, there might be supporter poles inside the duct. Use extra care,
when dealing with ducts equipped with supporters. When cleaning large rectangular or
round ducts the use of LIFA centering device (accessory) is highly recommended.
•Place the machine in a firm position.
•Choose a right sized brush (depending on the size of the duct). Make sure that the brush
isn’t too small or big for the duct that is going to be cleaned. Nylon grease /Tynex brushes
are meant only for grease exhaust duct cleaning.
•Make sure that the working area is cleared and there are no extra personnel.
•Ensure that all the employees performing the work have adequate personal protective
equipment.

7
Make sure that there is enough low pressure in the channel network and that LIFA HepaClean
or AirClean negative pressure unit (NPU) is installed correctly. The brushed off debris is removed by
sucking it to the NPU.
•Place the brush inside the ventilation duct that is going to be cleaned.
•Connect the machine into a current from the protective switch for motor.
•When the operator who is feeding the shaft into the duct gives a permission to start the
machine, the machine can be started.
Avoid to feed to the duct sharp angles and screws etc. This can damage the shaft.
Adjust the rotating speed of the brush. Note that when cleaning “soft” ducts the rotating speed should
be much lower than in normal ducts. Too high a rotation speed may damage the ventilation duct
channel.
The brush can be rotated to clockwise and counter clockwise. Use both rotating directions to achieve
the best cleaning result. In rectangular ducts, it may be required to clean one side first (with rotating
the brush in one direction only) and after that another side.
Feed the shaft evenly into the duct without excessive force. The use of excessive force may harm
the duct, machine or brush and influence on the cleaning result. Always insert the shaft gently and
smoothly into the ductwork, to prevent the brush from ‘jumping’ and leaving unclean spots into the
duct.
It is also advised to use the-one-and-only specially designed centering device and/or shaft holder by
LIFA in big ducts and/or when full rotation speed is being used.
GREASE DUCTS: LIFA Hydmaster brushing machine may be used for grease duct cleanings.

Service and Maintenance
When the machine is in daily professional use it should be delivered to its first regular maintenance
to the manufacturer or to repair shop that has been authorized by the manufacturer after six months
from the first commissioning date (approximately 100 hours). The warranty expires if the machine
has not been delivered to its first maintenance on time.
The following maintenance and upkeep work must be done in regular basis depending on the
purpose of which the machine is being used. This enables a trouble-free use.
General Cleanliness:
Keep the machine as free from dirt and dust as possible. Dirt and grease may cause defects in the
compressed air valves. The machine can be cleaned by wiping it with a rag.
Cleaning shaft:
The cleaning shaft must be cleaned every time after use. The dirt and grease that has collected
to the plastic surface can be removed with a mild grease removal detergent that is meant for plastic
surfaces. Some lubricant (synthetic Vaseline, lubricating oil etc.) must be put between the
turnbuckle and the outer bearing in the brush adapter regularly.
NOTE!
Possible repairs must be carried out by the manufacturer or a servicer authorized by LIFAair. Third
party repairs will void the warranty.

Troubleshooting
Possible problem situations and solutions are presented below. If you are not sure on how to handle
problem situations do not hesitate to contact us. Our experts are pleased to advice and help you in
a way we can get the desired outcome together.
1. Protective switch for motor does not stay on/does not go on (turn to construction and
control)
a) Make sure that the supply mains are attached to an electrical network with protective
grounding (230V/50Hz) and that the supply mains are in order.
b) Make sure that there is voltage in the electrical network and that a fuse has not burnt.
2. When loaded the machine does not stay on
a) When the machine is being used continuously for long periods especially with large brushes
the motor and the transmission may overheat. If that happens the automatics cuts off the
operation. The machine is ready automatically when it is cooled.
b) Make sure that there aren’t other machines that have a big power consumption connected to
the same electric circuit. The machine should have its own electric circuit so the machine can
get the power it needs.
3. The cleaning brush does not rotate on steady rotating speed
a) Make sure the level of the oil is sufficient. The minimum is in the +30 ºC the maximum in the
place of +80 ºC.
b) Make sure that the machine is placed firmly. If the machine has been used transported or
stored in uneven place there may be some air in the hydraulic hoses. Because of this the
brush motor may run unevenly for a while. Once the air has come out of the hose the motor
will start to run normally.
