Additional safety instructions for pneumatic tools

Air under pressure can cause serious injury:

- always shut off the air supply, drain hose of air pressure and detach tool from air supply, when it is not in use, before changing accessories or performing repairs;

- never direct the air stream at yourself or anyone else.

Hose hitting can cause serious injury. You should always check for damaged or loose hoses and fittings. Cold air should be directed away from the hands

Every time when there are used universal screwed connection (claw couplings), you should apply the protecting pins and connectors against the possibility of damage to the connections between the hoses and between the hose and tool. Do not exceed the maximum air pressure specified for the tool.

Never carry the tool, by holding it by the hose.

OPERATING CONDITIONS

You should also make sure that the source of compressed air allows you to create the proper working pressure and that it provides the required air flow. In the case of a too high air pressure, a reducer should be used together with a safety valve. The pneumatic tool must be powered by the system of a filter and lubricator. This will ensure, at the same time, the air, which is pure and moistured by oil. The state of the filter and lubricator should be checked before each use, and possibly clean the filter or refill shortage of oil in the lubricator. This will ensure proper operation of the tool and will extend its service life.

If you use any additional handles or supporting racks, you should make sure, that the tool is mounted correctly and securely. You should adopt an appropriate posture to counteract the normal or unexpected movement of the tool, caused by its torque.

Be careful of your work surroundings, the grinder machine can easily cut through something.

Do not use any grinding wheels and tools designed for grinding their surface side, for cutting.

Do not use any cutting discs or wheels for milling.

When you turn off the grinder, you should wait with its stacking, until a complete stop to the rotating tool.

Before the installation of additional equipment, you should make sure the maximum speed of the equipment is higher than the speed of the grinder. Do not use any equipment with handles of other dimensions than those specified in the instructions. Do not modify the grinding wheel mandrel to fit it to the diameter of the grip handle. Insert tool must be firmly and securely mounted in the tool holder. Do not use reduction rings and sleeves, in order to match the diameter of the tool spindle and grinding wheel. Do not modify the grinder holder to fit it to the mandrel diameter of the grinding wheel.

Do not operate the grinder in a place with a high risk of explosion. The sparks, which are produced during operation, can cause a fire.

After mounting the grinding wheel you should run it for about 30 seconds in a safe position. Immediately stop the device, if you observe a large vibration or other defects in the grinder behavior.

Any irregularities must be removed before the next launch of the grinder.

You should make sure that the grinding speed is not greater than the speed which is specified on the rating plate.

EN

During processing of certain materials, poisonous or combustible dusts and fumes can be created. Work in well ventilated areas and use personal protective equipment.

When you are selecting safeguard measures you should take into account the type of workpiece.

You should make sure, that sparks and debris created during operation do not cause any hazards.

Use personal protective equipment such as gloves, apron, helmet.

In the case of dropped tools with a mounted grinding wheel, before subsequent switching it on, you should carefully check the condition of the grinding wheel.

Before each use, you should check that none of the components of the product is damaged. If you notice any damage, you should replace the element immediately with new one, undamaged system component.

Before each use of the the pneumatic system, you should dry the moisture condensed inside the tool, compressor and pipes.

ATTENTION! To power the pneumatic tool you should use only compressed air. It is forbidden to use any other gas for that purpose, especially fl ammable gases.

Connecting the tool to pneumatic system

The figure shows the recommended connection of tool to the pneumatic system. Presented method will ensure the most efficient use of tool, and also it will extend the service life of the tool.

Let a few drops of oil with viscosity SAE 10 to the air intake.

To the thread of air inlet tightly and firmly screw the appropriate tip allowing for the connection of an air supply hose (II).

On the tool driver you should mount an appropriate grinding wheel. If the grinding wheel has a specified direction of rotation, then it must be consistent with the direction of rotation on the tool. Make sure, the grinding wheel is designed to work with pneumatic tools, and its permissible rotational speed is equal to or higher than the rotational speed of the grinder.

Make sure, that the switch – speed regulator was rotated in the position marked "OFF" (III).

Connect the tool to an air system by using the hose with an inner diameter of 10 mm / 3/8 “. Make sure, that the strength of the hose is at least 1.38 MPa.

Run the tool for a few seconds by turning the switch – speed controller to the stop in the direction of the position marked "ON". Make sure, that the tool does not issue any suspicious sounds or vibrations.

Adjust the rotational speed by using the switch - speed control. Rotation in the direction marked "ON" increases the speed and in the direction of the "OFF" reduces the speed until the cessation of rotation.

Installation and replacement of equipment (V)

Make sure, that the maximum rotational speed is higher, than the rotational speed of the grinder. You should follow the recommendations of manufacturers of grinding wheels in relation to their speed and the mandrel length, which should be mounted in the spindle.

Make sure, that the grinder has been disconnected from the compressed air supply.

By blocking with one key possibility of the spindle rotation, you should by using the second key loosen the nut of the tool holder.

Mount a piece of equipment, so at least 10 mm of the mandrel is located inside the spindle.

By using keys, tightly and firmly screw the nut which is locking the spindle. Remove keys before connecting the tool to pneumatic system with compressed air.

The grinder is equipped with air lubricator, which you can use when the compressed air supply system is not equipped with and lubricator. Lubricator should be installed at the inlet of compressed air to the tool, then you should screw to it the appropriate tip, which will allow for an air inlet hose connection (VI).

On the case of the lubricator there is the screw (VII), which is an oil tank valve, after unscrewing it, you should fill in the tank with oil designed for use in pneumatic tools, SAE viscosity 10, and then close the oil tank valve by tightening the screw. The lubricator optimal position for work is a vertical position with the air inlet facing downwards. During work you should regularly refill oil.

Operation of the sander

Choose the appropriate tool for a given operation mode. Before starting work, you must allow for grinding wheel to reach its full speed. Only the rotating grinding wheel should be applied to a workpiece.

You should apply only such pressure to the tool, which is required for the material processing. Too much pressure can damage the grinding wheels and increase the risk of injuries.

During work the sparks can occur and workpiece fragments of the workpiece can tear off. You should ensure that the that sparks and tear-off fragments would not create risks in the workplace.

MAINTENANCE

Never use gasoline, solvent, or any other flammable liquid to clean the tool. The vapors can be ignited, causing the tool explosion and serious injury.

EN
