• When sanding, do not use oversized sanding paper. Select sanding paper according to the manufacturer’s recommendation. Large sandpaper beyond the sanding pad is in danger of tearing and can cause entanglement, tearing or rebound of the sanding pad.

Further safety instructions for all operations

• Rebound and related warnings.
• Rebound is a sudden reaction force caused by stuck or entangled rotating grinding wheel, back cushion, wire brush or other accessories. Jamming or winding will cause the rapid stalling of rotating accessories, and then the runaway electric tool will move in the opposite direction of accessory rotation at the jamming point.
• For example, if the grinding wheel is entangled or stuck by the workpiece, the edge of the grinding wheel extending into the sticking point may enter the material surface and cause the grinding wheel to climb out or rebound. The wheel may fly to or away from the operator, depending on the direction of movement of the wheel at the sticking point Under this condition, the grinding wheel may break
• Rebound is the result of misuse of power tools and/ or incorrect operation procedures or conditions, which can be avoided by taking appropriate protective measures given below.
• Hold the power tool tightly so that your body and arms are in the right position to resist rebound. If there is an auxiliary handle, it should be used all the time, to maximize the control of the rebound force or torque when starting. If appropriate preventive measures are taken, the reaction torque or rebound force should be controlled at all times.
• Never put your hand close to the rotating attachment Attachments may bounce and touch hands.
• Don’t stand where the power tool may move in case of rebound. The rebound will drive the tool to move against the grinding wheel at the winding point
• Be very careful when working at sharp corners, sharp edges, etc. Avoid jumping and winding of accessories. Sharp corners, sharp edges and bouncing tend to wind the rotating accessories and causing rebound and out of control.
• Do not attach saw chain, woodcarving blade or toothed saw blade. These saw blades will produce frequent rebounds and out of control.

Power connect

To plug in the socket and use the power tool, make sure that the voltage of the power supply is consistent with the rated voltage of the tool. If the power supply voltage exceeds the rated voltage of the tool and is used by mistake, it will not only damage the machine, but also hurt people. If the voltage of the socket can not be determined, it must not be used. In addition, if the power supply voltage is lower than the tool specification voltage, it will also be harmful to the operation of the motor.

Assembly procedures

About sanding paper

Place the tool in the flat and soft surface before assembly of abrasive paper to ensure replacement quality. First take out the accessory abrasive paper from the tool box and mount it onto the disc. Back of the abrasive paper and the disc will adhere automatically with each other to achieve the functions of connection and conduction.

Sanding efficiency of the tool will reduce after it works for some time. It is necessary to replace the abrasive paper to improve its sanding efficiency. First turn off the electric tool, and disconnect the power plug; then remove the original abrasive paper. Abrasive paper on the disk shall be completely cleared to ensure that the newly-mounted abrasive paper is flat and firm, and will be easier for future replacement. Finally, put on the new abrasive paper.

The drywall sander makes use of the sand gravels on the abrasive paper and rotation of abrasive paper to grind surfaces of walls and other objects when it works. Abrasive paper is classified in sizes.Select the right type of abrasive paper in accordance with disc size of the tool. Abrasive paper can also be classified according to the number of abrasive grains. For abrasive paper of the same size, the more the number of abrasive grains on the paper, the smoother and flatter the sanding effect, correspondingly the sanding efficiency becomes low.

On the contrary, for the abrasive paper of the same size, the less the number of abrasive grains on the paper, the higher the sanding efficiency, but the finished surface becomes rough correspondingly. Therefore please purchase the right type of 220 (mm) abrasive paper as actually required during replacement. Take out the old abrasive paper; insert a hexagonal wrench into the hexagon socket hole in the threaded spindle in the center of abrasive paper sanding pad and rotate clockwise to remove the original sanding pad. Then put on the new abrasive paper sanding pad.
