water vapour from the air and moisture in the abrasive.
Caution! Before fi lling and emptying the sandblasting cabinet 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 cabinet chamber. Before refi lling the sandblasting cabinet chamber with
abrasive, ensure that the drain hole is properly closed. Do not exceed the maximum permissible abrasive volume. The screen
should not be covered with abrasive.
When replacing the abrasive, place a container for the used abrasive under the drain hole, then turn the drain hole locking pin
until it unlocks and then pull it out. Allow the abrasive to pour into the container. Clean the inside of the chamber of any spent
abrasive residue.
Lamp operation
The sandblaster is equipped with a lamp to illuminate the inside of the chamber during sandblasting. The lamp is located inside
the sandblasting cabinet chamber (X). 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 supply plug is connected to the socket on the back of the lamp switch casing (X). 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
Caution! Before using the sandblaster, check the condition of the seals. A self-adhesive sandblaster door sealing tape is included
to keep the chamber airtight. If the door seal has signifi cant signs of wear or does not provide a seal when the sandblaster is oper-
ating, it should be replaced with a new one. To do this, remove the old tape from the sandblaster door and replace it with new tape.
The air supplying the gun in the sandblasting cabinet 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 cabinet must be diff erent from that for supply-
ing 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 name-
plate, 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 cabinet chamber; the doors should be closed
and secured with the latch (XI). Connect the sandblasting cabinet to power and pneumatic supply and turn on the lamp inside the
chamber. 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-55847.
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-55849.
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.
Before starting maintenance, place a container for used abrasive under the drain hole, then turn the drain hole locking pin until
it unlocks, then pull it out and dump all the abrasive. Clean the sandblasting cabinet chamber using a soft hand broom, a brush
or jet of compressed air with pressure not higher than 0.3 MPa. If the abrasive remains in the suction hose, place a small metal
container in the sandblasting cabinet chamber. Close and snap the chamber doors, point the gun nozzle at the container internal
