Intended use
The device is intended for abrasive material processing by fine blast-
ing with various blasting media.
Among others, the following blasting processes are possible:
• Scale removing after hardening.
• Smoothing of plastic and diecasting moulds, compression
moulding dies and embossing dies.
• Shot peening of wearing parts.
• Derusting and removing of lacquer of/from components.
• Deburring of metal components after machining (e.g. turn-
ing, drilling, milling) and of duroplastic mouldings from injec-
tion moulding and shaped casting).
• Cleaning of plastic and rubber moulds, welds and soldered
parts.
• Preparation of surfaces for paint spraying, gluing and elec-
troplating.
• Matting and brightening (decorative blasting).
The application possibilities are versatile by:
• Use of mixed grit and glass bead blasting shots.
• Use of different grid sizes:
The precisely balanced relationship between the dosing cup
and blasting gun in addition to the special filter system allows
the use of all commercially available blasting media. Grit sizes
of between 1 mm (approx. 20 mesh) and 0.01 mm (approx.
400 mesh) can be processed.

Installation and starting the unit for the first time
Installation site
The unit must not be installed in an environment where there is a risk
of explosion or in rooms with a risk of explosion.
The unit must not be installed in damp rooms or in rooms with high
relative humidity.
Machine connections
Only connect the unit via a plug connector that allows disconnec-
tion from the electrical mains. The electrical connection must be
made according to the details on the rating plate and this operat-
ing manual.
The compressed air supply (input pressure) must not exceed 8 bar.
The unit operator must provide for a shutoff valve in the compressed
air connection line on the customer’s side, allowing disconnection of
the unit from the supply network.

Installation and starting the unit for the first time
In order to prevent the blasting shot contained in the cabin from
absorbing humidity, the unit should always be installed in a dry
place. This of course also applies to the storage place of the blasting
shot.
Before using the unit for the first time, the air treatment unit must be
installed on the right-hand side of the machine. The hand crank of
the filter-dust removal device must also be installed on the shaker
rod axle on the left-hand side.
1. A water separator is incorporated in the air treatment unit
in order to eliminate the water in the compressed air.
Care should be taken during installation that the water
separator is in the upright position.
2. The pressure gauge is screwed to the air treatment unit.
The desired blasting pressure is set at the pressure relief
valve. This pressure can be read on the pressure gauge.
3. The electrical connection is single phase, 220 V light cur-
rent. The green/yellow cable forms the earth lead.
4. The entire unit is switched on and off using the main
switch. In the “0” position, the unit is switched off. In the
“1” position, the unit and cabin lighting are switched on
simultaneously. In the “2” position, the fan is activated. The
latter creates negative pressure inside the cabin and en-
sures a clear view during the blasting process.
The fan must be switched off when the cabin remains
open for a prolonged period, during cleaning the main fil-
ter and when changing the blasting shot.
5. The control light only illuminates when the fan is switched
on. It simultaneously serves as a fuse holder and is
equipped with a 2 A / 250 V fine fuse. In case of overload,
the fine fuse burns out and the control light goes out. The
cap with the fuse holder can be unscrewed and the fuse
can be replaced by turning anticlockwise while simulta-
neously applying pressure to the front panel.
6. The electric foot switch operates the solenoid valve incor-
porated in the machine, which releases the compressed
air to the blasting gun. This only works with the fan running.

7. The safety end switch serves to interrupt the blasting proc-
ess if the cabin hood is open. If the cabin is opened during
blasting, the blasting process is interrupted automatically
in order to avoid accidents.
8. The dosing system and run-off container is equipped with
a patent quick-release lock.
9. The two screws on the cabin lid secure the window frame
and must be loosened in order to replace the viewing or
protection pane.
10. The dust collection containers are held firmly closed by
the clamping levers fitted to the sides. If the machine is in
constant use, the drawers should be checked daily for
overfilling.

JOKE®instruction manual

Filter system
The system consists of different types of filter:
1. The air supply rosettes allows the air aspirated by the fan to
enter the blasting chamber. Negative pressure results, which
prevents the blasting shot from escaping during blasting.
2. The air filter aspirates fresh air through the air supply rosettes,
thereby establishing a flow rate. Suspended matter and shat-
tered blasting shot can therefore be sucked into the two filter
cartridges before they re-emerge in the blasting chamber.
Only clean the filter with the fan switched off.
IMPORTANT!
Changing the filter cartridges
1. Open the rear maintenance hatch.
2. Unscrew the M10 securing nuts under the cartridges, unscrew
the threaded rods and remove the cartridge.
Installation is performed in reverse order.

Notes concerning blasting shot
The suitable blasting shot can be found in the JOKE®catalogue in
the “cleaning and blasting equipment” chapter. Take care to use
the shot in the dry state and free of lumps.
The suitable blasting shot for the various different requirements
can be selected and ordered directly from JOKE ®, stating the
order number.
Use of silicone-based or quartz-based blasting shot may cause se-
vere damage to the respiratory tract!
CAUTION
Use of quartz-based blasting shot is forbidden!
Do not use silicone-based blasting shot! Wear breathing protection!
Notes on blasting
It is advisable to hold the blasting gun at a distance of
approx. 40 - 60 mm from the workpiece and at an angle of 45 - 60°.
The gun should be passed evenly over larger areas in order to avoid
cloud formation. Under certain circumstances, finally blast the entire
surface again, but with a greater gun distance.
Fine profiling and sharp edges must only be blasted with fine grits
and at low pressure.
If surface improvement is to be achieved, work must be performed
several times with different grit sizes (from coarse to fine). The blast-
ing shots MK 40/90, followed by MK 90/150 and finally MK 245 are
recommended for this purpose. Subsequent blasting with GPF fine
glass beads results in a silk gloss.
Restoration work is mainly performed at low pressure with the use of
glass beads, high-grade corundum and walnut shells.
