4,Installation and precautions                                                             

4.1 The equipment must be well grounded and must use a standard three-pole power outlet.
4.2 The equipment shall be installed on a stable, non-vibration workbench, and the environment shall be ventilated and dry, with a temperature of 10ºC -30ºC; with a relative humidity of <85%, and no corrosive gas and conductive dust around.
4.3Open the present machine, remove the winding film on the whole machine and remove the accessories, put the packaging bottom plate together with the whole machine pad high, remove the four bolts from the following with the wrench, and then move the whole machine to the work surface. Cover one end of the drain with the throat collar into the drain connector at the rear of the device; move to the middle of the joint to the drain, and tighten the screw of the collar to secure the drain. Then screw the inlet pipe into the inlet nozzle, so that the glue pad and the inlet nozzle contact and close well.






4.4 Determine the placement position of the equipment according to the inlet and drainage conditions, and adjust the 4 adjustable damping pads to make the basic level of the equipment and stabilize it.
4.5 Grinding plate can be quickly replaced, two hands hold the grinding plate gently lift to unload; the other grinding plate two hands flat, visual grinding plate three piston rod holes and three piston rod basic fall, feel one of the hole corresponding, the slight swing of the other two also corresponding to the plate flat insertion, and then with the hand pressure, make the grinding plate and the ground seat positioning surface completely contact.
4.6 Installation method of metalsandpaper and polished fabric
Wipe the upper plane of the grinding plate (must be clean without any dust or bulge), paste the gold phase sandpaper or polished fabric with pressure-sensitive adhesive on it, visually see the distance between the sandpaper or fabric and the edge of the plate, and make it with the hand to bond firm.

Table 1                   Grinding parameters of the seat

	Gold sand paper particle number	Grinding throw plate turn number	Requirements to be met
fine grinding	240#-400#	400 r/min	Remove the processing marks left by the cutting
Half fine grinding	600#-800#	400 r/min	Remove the grinding marks of rough grinding
finish grinding	1000#-2000#	400 r/min	Grclose to the mirror
Note: The size of sand paper and grinding speed shall be appropriately selected according to the requirements of metaltest sample. When the sample requirements are general, the semi-fine grinding step can be omitted. When the sample requirements are high, the grinding step should be added appropriately.
