damage the tool or impair its operation.
Observe the general safety principles when working with spraying materials. Wear suitable personal protective equipment such
as goggles, masks and gloves.
There is a risk of absorption of spraying agent or preservative particles during work or when performing maintenance activities,
caused by: - insuffi cient natural or forced ventilation, - improper atomisation pressure, - insuffi cient optimisation of spray param-
eters to reduce contamination, - improper distance between tool nozzle and application area of spray agent, the distance should
be determined depending on the agent used, - absorption of solvent vapours or other hazardous substances, - improper use e.g.
use of improper spray agent.
Never leave the assembled pneumatic system unattended by a person authorised to operate it. Keep children away from the
assembled pneumatic system. High-pressure compressed air supply may cause the tool to recoil in the direction opposite to that
of the spraying agent ejection. Special care should be taken as jet forces can, under certain conditions, cause multiple injuries.
It is recommended to try the tool out before beginning work. It is recommended that persons working with the tool are properly
trained. This will signifi cantly increase work safety.
Observe the instructions of the abrasive material manufacturer and use them in accordance with the presented principles for
personal, fi re and environmental protection. Failure to follow the instructions of the abrasive material manufacturer can lead to
serious injury. In order to determine compatibility with the abrasive materials used, a list of materials used for the construction of
the tool will be available on request.
When working with the use of compressed air, energy is stored in the entire system. Care must be taken when working and during
breaks in order to avoid the risk connected with the stored compressed air energy. Due to the possibility of electrostatic charge
build-up, measurements should be taken to ensure whether the tool needs to be grounded, or whether a surface dissipating elec-
trostatic charges and/or compressed air system is necessary. It is required that the measurement and installation of such system
is carried out by personnel with appropriate qualifi cations.
Never point the spray jet at a source of heat or fi re, as this may cause fi re.
Repairs of the tool can only be performed by qualifi ed personnel using original spare parts.
PRODUCT OPERATION
Device assembly
Secure the legs to the underside of the sandblasting cabinet using M6 x 12 mm bolts, washers and M6 nuts. Position the cabinet
on the assembled legs. Secure the sandblaster tray (III) to the underside of the cabinet using M6 x 20 mm bolts, washers and M6
nuts. The shelf (IV) should then be attached to the legs of the sandblaster using M6 x 12 mm bolts, washers and M6 nuts. Inside
the tray, using M6 x 12 mm bolts, washers and M6 nuts, fi x the intake pipe as shown in the illustration (V). Inside the sandblasting
cabinet, place the screen so that the suction line is on the outside of the screen (VI). Put the free end of the abrasive suction hose
onto the end of the suction line to the gun (VI). Tighten the hose clamp with a screwdriver. Ensure that the suction hose is properly
secured and does not slip out during operation. Slide the free end of the hose supplying the compressed air to the gun (attached
to the gun handle) onto the spigot inside the sandblasting cabinet (VII). Tighten the hose clamp with a screwdriver. Ensure that
the supply hose is properly secured and does not slip out during operation. Do not overtighten the clamp screw as this may dam-
age the hose. Put the clamp on the glove and then roll back the glove cuff edge onto the clamp (VIII). Place the glove inside the
sandblasting machine chamber so that the clamp with the rolled back cuff wraps around the opening fl ange in the front panel of
the chamber. Then use a screwdriver to tighten the clamp (IX). Make sure that the right glove is in the right-hand opening and the
left-hand glove is in the left-hand opening. Tighten the clamps so that the glove does not slip out from the clamp and is not cut by it.
Dust extraction connector
CAUTION! For dust extraction, use only a dedicated dust extraction system or an industrial hoover fi tted with a high fi ltration
effi ciency fi lter designed for class M dust extraction. It is forbidden to use domestic hoovers or any other equipment not designed
for dust extraction.
Remove the dust extraction connector cover located on the left side of the cabin, then connect an external dust extraction system
to the connector. The venti is located at the rear of the sandblasting cabinet. Remove the cover from the vent before starting work.
Abrasive
Make sure that the abrasive is suitable for pneumatic sandblasting machines. The recommended abrasive grain size should be
between 0.18 and 0.25 mm. The concentration of harmful substances in the abrasive should not exceed the following levels: - anti-
mony, lead, cadmium, tin, arsenic, beryllium, chromates, cobalt, nickel - total 2% of mass fraction; - arsenic, beryllium, chromates,
cobalt and nickel - total 0.2% of mass fraction; - beryllium, chromates, cobalt, cadmium - separately 0.1% of mass fraction; - metal
chemicals should be calculated as metal elements and chromates as CrO ; - pure crystalline silica (SiO ) - 2% of mass fraction.

The abrasive material gets worn out and contaminated during use. Replace the abrasive periodically. Replacement time depends
on the work intensity; observe the abrasive colour and the work effi ciency. If the colour of the abrasive accumulated in the chamber
diff ers signifi cantly from the colour of the new abrasive, it means signifi cant dirt and in this case the abrasive must be replaced.
Similarly, if the effi ciency is signifi cantly reduced, the abrasive should be replaced.
The abrasive must be completely dry to ensure that it is free fl owing; the fl ow must be adequate to ensure correct work. Do not
store abrasives in humid rooms and do not expose them to sudden changes in temperature. This can lead to condensation of
