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: - insu ffi cient natural or forced ventilation, - improper atomisation pressure, - insu ffi 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 signi fi 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 quali fi 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 quali fi ed personnel using original spare parts.
PRODUCT OPERATION
Tool assembly
Caution! The tool is equipped with adhesive sealing tape, which should be used to seal the sandblasting machine chamber.
To disassembly the sandblasting machine, remove the old tape from all the tool elements and replace it with a new one before
reassembly.
Apply strips of sealing tape (II) to the shorter edges of the front panel and to the longer edges of the side panels.
Assemble all four panels of the sandblasting machine chamber (III) together using screws and nuts.
Apply sealing tape to the sti ff ening connector from the side that comes into contact with the chamber panels, and then mount
the sti ff ening connectors (IV) in the corners at the lower edge of the sandblasting machine chamber using screws and washers.
Apply sealing tape to the entire lower edge of the sandblasting machine chamber. Then mount the bottom of the sandblasting
machine chamber using screws and nuts. Mount the legs (V) in the corners.
Place the sandblasting machine on legs and mount the cone fi lter and the lamp handle using screws and nuts inside the sand-
blasting machine chamber. Install the lid latch (VI) outside the chamber.
Use the screws to mount the chamber lid and then fi x the open lid lock (VII) on the left.
Mount the lamp in the brackets so that the light element is directed towards the interior of the sandblasting machine chamber and
having loosened the plastic nut of the opening (VIII), run the lamp cable through the hole in the side panel. Connect the power
supply cable wires to the contacts inside a junction box. Make sure the wires are connected in a correct way; the blue wire should
be connected to the blue wire and the brown/grey wire to the brown/grey wire. Then fi x the junction box to the side panel using
screws (IX).
Install a fl at fi lter (X) on the rear panel.
Put the clamp on the glove and then roll back the glove cu ff edge onto the clamp (XI). Place the glove inside the sandblasting ma-
chine chamber so that the clamp with the rolled back cu ff wraps around the opening fl ange in the front panel of the chamber. Then
use a screwdriver to tighten the clamp (XII). 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.
Screw the free end of the compressed air supply hose of the gun (attached to the gun handle) to the hole in the side panel of the
chamber (XIII). Screw the free end of the abrasive suction hose (attached near the gun nozzle) to the hole in the bottom of the
chamber (XIV).
Mount the bracket to the screen using screws and nuts (XV). Place the bracket as close as possible to the screen centre. Place
the screen at the bottom of the sandblasting machine chamber with the bracket pointing down so the suction hose runs through a
gap made by the screen bevelled corner (XVI).
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,
