Note 1) When tightening an auto switch mounting screw, use a
watchmaker’s screwdriver with a grip diameter of 5 to 6 mm.
Also, set the tightening torque to be 0.037 to 0.074 lbf·ft (0.05 to
0.1 N·m). As a guide, turn 90° from the position where it comes
to feel tight.
Note 2) Set the tightening torque of a hexagon socket head set screw
(M4 × 0.7) to be 0.74 to 0.89 lbf·ft (1 to 1.2 N·m).
1. Fix it to the detecting position with a set screw by installing an auto
switch mounting bracket in cylinder tie-rod and letting the bottom
surface of an auto switch mounting bracket contact the cylinder tube
firmly. Fix it to the detecting position with a set screw. (Use a hexagon
wrench.)
2. Fit an auto switch into the auto switch mounting groove to set it
roughly to the mounting position for an auto switch.
3. After confirming the detecting position, tighten up the mounting screw
attached to an auto switch, and secure the auto switch.
4. When changing the detecting position, carry out in the state of 2.
∗
To protect auto switches, ensure that main body of an auto switch
should be embedded into auto switch mounting groove with a depth of
15 mm or more.
