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
water vapour from the air and moisture in the abrasive.
Caution! Before fi lling and emptying the sandblasting machine chamber of the abrasive material, make sure that it has been dis-
connected from the air and power supply. The pneumatic and electric lines must be disconnected from the power supply sources.
The abrasive is poured directly into the sandblasting machine chamber. Do not exceed the maximum permissible abrasive vol-
ume. The screen should not be covered with abrasive.
When replacing the abrasive, place a container under the sandblasting machine for the used abrasive and then unscrew the end
of the suction hose, which is screwed into the bottom of the sandblasting machine chamber. Allow the abrasive to pour into the
container. Clean the inside of the chamber with special regard to the thread in the hose opening and connection and screw the
end of the suction hose back into the bottom of the sandblasting machine.
Lamp operation
The sandblasting machine has a lamp inside the chamber, which allows to illuminate the interior of the chamber during sandblast-
ing. Use only the lamp supplied with the product. Do not point the abrasive jet directly at the lamp or its cable. This can lead to
damage to the lamp or cable, or result in an electric shock. Use only the power adapter supplied with the tool to power the lamp.
The power adapter plug should be connected to the junction box. Make sure the on/off switch of the lamp is in the off position - O
before connecting the tool to the power supply. Switch the lamp on by moving the switch to the on position – I.
Sandblasting
The air supplying the gun in the sandblasting machine chamber should be fi ltered and dried. Do not place an oiler in the com-
pressed air supply system. The compressed air supply system for the sandblasting machine must be diff erent from that for
supplying pneumatic tools, e.g. wrenches. Make sure that the supply system is of proper performance and that it will provide
appropriate pressure. If the air pressure in the supply system is higher than the maximum value in the technical data table and on
the nameplate, connect the gun using the pressure reducing valve and pressure gauge that will allow to regulate the pressure. No
pressure drop should occur during sandblasting, as this will result in uneven work results.
The sandblasted object should be placed on the screen inside the sandblasting machine chamber; the lid should be closed and
secured with the latch. Connect the sandblasting machine to power and pneumatic supply and turn on the lamp inside the cham-
ber. Slide your hands into the gloves and grasp the gun. Point the gun nozzle outlet at the object to be sandblasted, press and
hold the gun trigger. The gun trigger release will stop the blow out of the abrasive from the gun nozzle.
Do not hold the sandblasted object in hand when sandblasting. Avoid pointing the abrasive jet directly at the gloves. This will lead
to faster wear and tear of the gloves, which may result in glove perforation during operation and cause serious injury.
Use the gun in circular movements over a sandblasted surface. Avoid pointing the abrasive stream at one point. Observe the
work results and adjust the pressure. Use the appropriate nozzle. The higher the pressure, the higher the intensity of the abrasive
jet, which results in faster and deeper sandblasting. Smaller nozzle diameter allows for more concentrated abrasive jet which
results in easier sandblasting of small objects. Larger nozzle diameter allows for wider abrasive jet which results in more eff ective
sandblasting of larger surfaces.
Replace the nozzle by unscrewing the ring around the nozzle, cleaning the nozzle mount, nozzle replacement and mounting it
using the ring. Use only the supplied nozzles or the nozzles from the YATO YT-55844 set.
If the nozzle becomes clogged during operation, stop working, disconnect the machine from the pneumatic and power supply,
then remove the nozzle and try to clean it. Use a plastic brush for cleaning. Do not use sharp or metal tools. If the cleaning of the
nozzle fails, replace it.
Caution! Make sure that the unit has been disconnected from the pneumatic and power supply before any replacement or ad-
justment works.
Gloves wear out during operation and should be inspected for signs of wear before each use - whether there are no visible signs of
damage, abrasion, tears etc. If any, replace the gloves. Sandblasting machine gloves are available separately as YATO YT-55846.
The transparent part of the lid may fade during operation. To prevent loss of visibility, the middle part of the lid is covered with
a transparent protective fi lm. Replace the protective fi lm each time the previous one becomes dull and does not allow for work
observation. Protective fi lms are available separately as YATO YT-55845.
MAINTENANCE, TRANSPORT AND STORAGE
Warning! Make sure that the unit has been disconnected from the compressed air and power supply before performing any
maintenance works, transport or storage.
