LIFA HYDMASTER 40
Lifa Hydmaster 40 is a multifunctional cleaning machine for entilation ducts. Hydmaster
40 is especially designed for tasks that require exceptionally strong force. It is designed
for demanding tasks and for rectangular and circular ducts. The special feature is its
strong motor torque, which is done hydraulically. Hydmaster 40 is designed and
manufactured according to international quality and en ironmental management system
ISO 9001:2008 and ISO 14001:2004
Hydmaster 40 is operated with normal electricity (single-phase current) and is notably
more silent than pneumatically operated machines. The hydraulic motor pro ides an
alternati e to pneumatically operated machines that need compressors in order to work.
The machine unit use hydraulic oil in power transmission. Inside the shaft there is: carbon
fibre reinforced hoses are inside a polypropylene co er; flexible glass fibre rod keeps the
shaft in the duct so it is easy to direct in it.
Hydmaster 40 is designed for ducts that ha e a diameter from D 315 mm to D 1200 mm
(12.4 – 47.25 inches) The rotating speed of the brush has a stepless speed ariation from
340 to 650 rpm.
The length of the shaft is 40 m which enables the cleaning of 75 meters (246 feet) of duct
when accessed in one ser ice hatch (access door) to both directions.
The most ad anced model of Hydmaster 40 has a camera and a screen so it is possible to
follow the result/progress of the cleaning work in the screen. The screen also shows
possible obstacles for example sound silencers etc.
Since the Hydmaster 40 has exceptionally strong motor torque it is possible to use
o ersized brushes especially in ducts getting smaller in diameter.
Lifa Y-Gear (accessory) brings efficiency to cleaning in cur es and corners of rectangular
ducts of 250 mm - 1200 mm (9.8 - 47.25 inches).
For exceptionally wide rectangular ducts Lifa 3 Brush- gear, 100 mm - 300 mm (9.84 –
11.81 inches)

The machine cannot be covered durin the operation
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 should be kept as clean as possible. When the shaft is pushing the shaft
back to the drum it should be cleaned with a cloth. After the work has been completed
the brushes and the shell of the cleaning shaft must be cleaned, before transporting
the machine into another location
2. General Safety
It is forbidden to stay in immediate contact with the machine while it is operating.
3. The safety of the operator
The person/persons who are performing the work should use personal protection:
filtered mouth mask, helmet, earmuffs, goggles, o erall, protection shoes and other
necessary protecti e equipment that the task at hand requires.
Hydmaster 40 has a strong rotating force. Clothes or hairs can easily get caught in the
brush and cause damage or accidents. The brush has to be placed always in the
entilation duct before starting the machine. The machine cannot be used when the
brush is outside the entilation duct. Due to the great rotating force Hydmaster 40 is
recommended to be used by two persons. One who directs the shaft into the duct, and
another who feeds/draws the shaft and controls the rotation of the brush.
4. The safety of the workin environment
Make sure that the lightning, air conditioning, latter and trestles 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 are any flammable liquids, gases, dust or other sensiti e
substances. Use antistatic brushes and safety ground by following the special
instructions in difficult conditions.

3. Transportation
During the transportation, the machine has to be tied firmly in order to pre ent any
damage to the machine or people.
The machine should be transported, used and stored in an upright position.
Before use make sure that all the components are in place and that the machine
functions well.
The equipment has to be protected from humidity, ibration and hits. It must not get
wet.
4. Positionin
The machine has to be placed firmly (locking wheels) and in straight position in order to
make sure its operation. The free rotating of the brush has to be ensured. The machine
has to be placed far enough from walls and other obstacles.
Make sure that the machine is placed firmly and straight and protect the machine
from ibration and weather influences.
Ensure that the brush rotating normally/free (before putting into duct/pipe)
Permitted working temperature is from 5ºC to 50ºC
5. Electrical connections
Hydmaster 40 is operated with one phase current and has a protecti e grounding.

THE USE OF THE MACHINE
Before beginning the work check the channel network with Lifa DuctTruck
(accessory). There may be air olume 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 Centring de ice (Accessory) is highly
recommended.
Choose a right sized brush (depending in 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 for cleaning the grease ducts. The combination brushes
are meant to use only in grease duct cleaning
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 fast rotation speed
may damage the entilation duct channel. Only softest brushes may be used.
Make sure that the working area is cleared and there are no extra personnel.
Ensure that all the employees performing the work ha e adequate protecti e
equipment.
Make sure that there is enough low pressure in the channel network and that Lifa
HepaClean or AirClean is installed correctly.
Connect the machine in to an electrical network with grounding.
Place the brush inside the entilation duct that is going to be cleaned.
Connect the machine into a current from the protecti e switch for motor.
When the shaft is being pushed to the duct a oid sharp angles and screws etc.
which can damage the shaft, especially sharp edges of duct opening.
When the operator who is feeding the shaft in to the duct gi es a permission to start
the machine, the machine can be started.
The brush can be rotated to clockwise and counter clockwise. Use both rotating
directions in order to make sure the best possible 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 steadily (slowly) in to the duct without excessi e force. The use of
excessi e force may harm the duct, machine or brush and influence to the cleaning
result.
