Adjusting the mounting surface of the outer flange
4
Adjust the mounting surface of the outer flange. In order to adapt to the different thickness of grinding
wheel, cutting wheel and other accessories, it is necessary to properly adjust the mounting surface of the
outer flange. If a thicker grinding wheel is used, the protrusion on the outer flange shall be placed inward (see
Figure 1). If a thinner cutting or diamond cutting wheel is used, the protrusion on the outer flange shall be
placed outward (see Figure 2). To ensure that the grinding/cutting wheels are fixed.

Adjusting the wheel guard
5
Put the wheel guard in the groove of the spindle collar, screw the wheel guard to the required position
and fasten it. Ensure that the grinding wheel can rotate freely in the wheel guard after tightening.
Precautions for use
If the machine is seriously hot, please let your machine run for 2-3 minutes without load to cool the motor.
Do not start the machine when the grinding wheel or other working accessories are in contact with the
workpiece.
Please start working after the machine runs to the maximum speed. Do not increase the friction between
the grinding wheel and the workpiece to improve efficiency, the rotating speed of the grinding wheel will
decrease, and the working time will be prolonged. When grinding, always keep the angle between the
grinding wheel and the working surface 15-30°. Large working angle will cause uneven working surface and
affect surface quality. Please keep the angle grinder moving forward, backward and cross when working.
When using the diamond cutting wheel, it is seriously hot and causes a spark along the entire circle of the
rotating grinding wheel. At this time, please stop using it to cool it and run it for 2-3 minutes without load.
Please ensure that the workpiece is well clamped and does not move.
Maintenance
Before performing any replacement work on the machine, be sure to pull out the plug first.
This power tool can maintain normal operation without applying lubricating oil or special maintenance. The
machine has no parts for user replacement.
Simply maintain the machine according to the following requirements.
1. Clean the machine with dry rag after use. Attention: Never use water or chemical cleaning agent to clean
the machine, so as not to affect the performance of the machine enclosure or cause electric leakage and
other accidents.
2. Always keep the air inlet of the motor clean and unobstructed to prevent debris from accumulating at the
air inlet and affecting the cooling of the motor.
In addition, try not to use it in dusty environment. If the power cord is damaged, in order to avoid danger, it
must be replaced by the manufacturer, authorized maintenance center or equivalent qualified professionals.
