1. Avoid contamination of the environment
The machine should be kept as clean as possible. When the cable is being pushed 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,overall, protection shoesand other necessaryprotective equipment
that the task at hand requires.
Lifa Duct Control Cleaning Robot has a strong rotating force. Clothes or hair can easily get caught in
the brush and cause damage or accidents. The brush has to be placed always in the ventilation duct
before starting the machine. The machine cannot be used when the brush is outside the ventilation
duct. Because of the great rotating force, the Duct Control Cleaning Robot is recommended to be
used by two persons. One who drives and controls the robot in the duct and another whofeeds/draws
the cables (electrical cable and pneumatic hose).
4. The safety of the working 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 sensitive substances. Use antistatic brushes and safety
ground by following the special instructions in difficult conditions.
5. Cable (electrical)
Be careful not to damage the cable. If the cable is damaged take immediate contact to your local
distributor. If the cable has been scratched only it can be coated again with a heat shrinkable tube.
During the storage and transportation, the cable has to be reeled. Always make the reeling so that
other end is free so that all the twists/kinks are taken out.
6. Compressed air connection
Make sure that the compressed air feed matches to the information on the CE-plate and the
operating instructions. The connector for brush motor is CEJN 320 series, other analogic
connectors: Rectus 25, Tema 1600 and JWL520/530, all Euro-standard 7.6 (7.4).
The connector for air/liquid jetting is CEJN 221 or Rectus series 21.
