2Place the rail slowly on the base mounting surface, and then temporarily fasten the rail while making it contact the base reference surface.
Standard Grade improved 3When subjected to impact, vibration, heavy load or requiring high precision, the fixing methods in Figures 1 to 3 are recommended.
4Use a torque wrench to tighten the mounting bolts to the specified torque. (Refer to Table 1 for the specified torque.)
