PRODUCT CHARACTERISTICS

Sandblast cabinet is a table-top sandblasting tool. Sandblasting is the mechanical removal of rust and/or paint coatings from objects using a jet of abrasive material (abrasive) ejected from the gun nozzle by means of a jet of compressed air. Since sandblasting takes place inside the sealed chamber, a dusting of the abrasive material is limited to a minimum. The correct, reliable and safe operation of the tool depends on its proper use, therefore:

Read and keep this entire manual before the first use of the tool.

The tool supplier shall not be liable for any damage resulting from failure to comply the safety instructions and recommendations specified in this manual.

ACCESSORIES

The unit is delivered disassembled and must be assembled according to the instructions given below before starting work. The product is delivered with a blast gun, additional nozzles and a pair of protective gloves. Abrasive is not supplied with the tool.

SAFETY INSTRUCTIONS

Warning! Close and secure the door before starting work. Unsecured doors can cause serious injuries.

Warning! Disconnect the machine from the air and power supply before opening the lid and before performing any maintenance works.

The abrasive and compressed air jets are hazardous. Never point the tool outlet towards people - abrasives or compressed air can cause body trauma or other injuries. Injection of lubricant can cause necrosis or even loss of limb. In case of injection, seek medical attention immediately.

Due to multiple hazards, read and understand the safety instructions before starting installation, operation, repair, maintenance and alteration of accessories or when working in the vicinity of a pneumatic tool. Failure to do so may result in serious injury. Pneumatic tools may only be installed, adjusted and assembled by qualified and trained personnel. Do not modify the pneumatic tool. Modifications can reduce efficiency and safety, and increase the risk for the tool operator. Do not throw away the safety instructions, they should be handed over to the tool operator. Do not use the pneumatic tool if it is damaged.

Operators and service personnel are required to receive appropriate training in the use and repair of the equipment.

It is forbidden to use any other gases instead of compressed air. The use of gases may lead to serious injury, cause fire or explosion. When connecting the tool to the compressed air system, consider the space required for the hose to avoid damaging the hose or connectors.

Effective ventilation should be provided at the workplace. Lack of effective ventilation may result in health hazards, cause fire or explosion. The tool is not intended for use in explosive atmospheres. Use the tool away from heat sources and fire as this may

EN

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: - insufficient natural or forced ventilation, - improper atomisation pressure, - insufficient optimisation of spray parameters 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, fire 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 electrostatic 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 qualifications.

Never point the spray jet at a source of heat or fire, as this may cause fire.

Repairs of the tool can only be performed by qualified 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 stiffening connector from the side that comes into contact with the chamber panels, and then mount the stiffening 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 filter and the lamp handle using screws and nuts inside the sandblasting machine chamber. Install the lid latch (VI) outside the chamber.

Use the screws to mount the chamber lid and then fix 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 fix the junction box to the side panel using screws (IX).

Install a flat filter (X) on the rear panel.

Put the clamp on the glove and then roll back the glove cuff edge onto the clamp (XI). Place the glove inside the sandblasting machine chamber so that the clamp with the rolled back cuff wraps around the opening flange 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: - antimony, lead, cadmium, tin, arsenic, beryllium, chromates, cobalt, nickel - total 2% of mass fraction; - arsenic, beryllium, chromates,

EN

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_3 ; - pure crystalline silica ( SiO_2 ) - 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 efficiency. If the colour of the abrasive accumulated in the chamber differs significantly from the colour of the new abrasive, it means significant dirt and in this case the abrasive must be replaced. Similarly, if the efficiency is significantly reduced, the abrasive should be replaced.

The abrasive must be completely dry to ensure that it is free flowing; the flow 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 filling and emptying the sandblasting machine chamber of the abrasive material, make sure that it has been disconnected 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 volume. 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 sandblasting. 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 filtered and dried. Do not place an oiler in the compressed air supply system. The compressed air supply system for the sandblasting machine must be different 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 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 effective 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 adjustment 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 film. Replace the protective film each time the previous one becomes dull and does not allow for work observation. Protective films 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.

EN

Before performing any maintenance works, unscrew the hose mount from the sandblasting machine bottom and remove all abrasive. Clean the sandblasting machine 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 machine chamber. Close and snap the chamber lid, point the gun nozzle at the container internal part and with the minimum working pressure empty the hose as during work.

Remove the flat and cone filters and clean them with jet of compressed air with pressure not higher than 0.3 MPa. If the filters are too dirty, replace them.

Clean the machine housing with a damp cloth and then wipe dry.

Transport and store the unit in its working position. The place of storage should protect the machine from access by unauthorised persons, especially children. The place of storage should be shaded and well-ventilated to prevent water vapour condensation. The place of storage should provide protection against precipitation. Do not place anything on the machine.

Transport the unit in the working position, emptied of abrasive. In the case of longer transport distances, the machine must be protected against damage by means of an additional packaging (cardboard box, box).
