Drill Whiling drilling holes, pay attention to the following points:
Use a 14 drill bit to drill the holes at the positions where theexpansion bolt holes are marked.
While drilling holes, keep the drill bit vertical to the ground andtightly hold the drilling machine.
Keep the depth of holes equal to the length of expansion bushplus cone. Keep the depths of all holes equal.
While drilling, use a blower to remove dust.
If the floor is too hard and smooth to locate the drill bit, youcan cut a dent at the desired position with the sample drill firstto help locating the drill bit.
Expansion Bolt Installation
Before installation, use a cleaner to clean the inside and outsideof all the holes, and then measure the space between holes. Forholes with large deviation, it is necessary to reposition and re-drillthe holes.

Take the gasket and nut out of the expansion bolt. Put the expan-sion rod and expansion bush vertically in the hole and hammer theexpansion bolt fully into the ground.
The expansion bolt is M12 100, which is attached to the cabinet.
Cabinet Fixing
Leveling Move the cabinet and place its four anchors at the positions markedfor them. Place a horizontal ruler on the top of the cabinets intwo perpendicular directions to check the horizontal level. If thecabinet is slanted, adjust the adjustable nuts of the four adjustablelegs of the cabinet to level the cabinet.
Cabinet Fixing Lock the four pressure plates onto the four anchors of the cabinet,and install them completely, as shown in Figure 44. Screw downthe nuts of the expansion bolts to fix the cabinet firmly on the floor.The fastening moment of force should be 45 N m.
