(1) Plug-in type The leakage protection device should be installed on the vibrator motor power supply. The selection of fuse should meet the requirements, and the zero connection should be safe and reliable. If the neutral line of motor is not connected properly, it is strictly forbidden to start it up.
(3) When the vibrator stops being used, the motor should be turned off immediately; when the vibrator is moved, the power supply should be cut off to ensure safety. Do not use hoses and cables to pull or pull the motor.
(4) When the vibrator is operating, the bending radius of the hose shall not be less than 50cm; the hose shall not be broken.
(6) When the vibrator is started, it must be controlled by the operator. The vibrator rod that is started must not be placed flat on a hard object such as a steel plate or cement board to avoid damage and danger.
(3) The mortar mixer
has two discharging methods: one is to tip the mixing drum, with the mouth of the barrel facing downwards, and the material is discharged; the other is to make the mixing drum stationary, and there is a discharge port at the bottom to discharge the material. Although the latter is convenient for discharging, sometimes slurry leaks due to loose door closing at the discharging port, so the tipping type discharging is generally used. Key points for safe use of
mortar mixer:
(4) Mortar mixer should use a one-way switch. (5) The mortar mixer shell must be installed with protective grounding (zero), and the grounding resistance of and should not be greater than 4Ω.
