Hand-push Cement Ground Grinder 220V. The pure copper motor is of high quality and the product is sturdy and durable. The new statorand rotor of the motor can easily realize the conversion of electrical energy and mechanical energy. Diamond chassis is sharp, hard, wear-resistant, work efficiency and high quality. High performance, stable life, long service life. T floors can also be fully hardened and work can be done at the root of the wall. The input voltage should not be too low. When using, first lift the machine head off the ground, and then turn on the switch. When the machine head rotates normally, gently place it on the ground.
