Do not apply strong impact or excessive moment tothe slide table (slider).Since the slide table (slider) is supported by precisionbearings, do not subject it to strong impact or excessivemoment when mounting workpieces.2. Perform careful alignment when connecting to aload which has an external guide mechanism.Mechanically jointed rodless cylinders can be used with adirect load within the allowable range for each type of guide,but careful alignment is necessary for connection to a loadwhich has an external guide mechanism. Since fluctuation ofthe center axis increases as the stroke becomes longer, use amethod of connection which can absorb the variations(floating mechanism).3. Do not put hands or fingers inside when the body issuspended.Since the body is heavy, use eye bolts when suspending it.(The eye bolts are not included with the body.)CautionMountingHandling1. Do not unnecessarily alter the guide adjustmentsetting.The guide is preadjusted at the factory so that readjustment isnot required under normal operating conditions. Do notinadvertently move the guide adjusting unit and change thesetting.Caution2. Air leakage will result from negative pressure.Take precautions under operating conditions in which negativepressure is increased inside the cylinder by external forces orinertial forces. Air leakage may occur due to separation of theseal belt.CautionSwitch mounting grooveHandlingMounting of Auto Switch1. Insert the auto switch into the cylinder , s switch mountinggroove, then slide it sideways in the direction shown belowand place it inside the switch spacer (with the spacerpositioned over it).2. Use a flat head watchmakers’ screwdriver to fasten the switch,tightening with a torque of 0.05 to 0.1 N·m. As a rule, it shouldbe turned about 90° past the point at which tightening can befelt.BMP1-032Auto switch8-11-96
