Head Directions

The head can be mounted in four directions. To remove the head,

turn the head by 45° as shown in figures A and B below.

To change the direction of the head, make sure that the protruding

part of the rotating lever engages with the groove of the plunger.

Then turn the head clockwise or counterclockwise to the desired

direction. At that time, make sure that the groove of the plunger is

located under the rotating lever. If the direction of the head is not set

when the plunger is rotated by 45°, the groove of the plunger presses

the rotating lever. The head, plunger, or the built-in switch may be

damaged as a result.

Head Direction Changes

Be sure to check the mechanical lock and solenoid release functions

when mounting the D4BL.

If the head direction is changed, recheck the tightening torque of

each of screw. Make sure that no foreign materials will penetrate

through the key hole on the head.

Mounting the Cover

When tightening the cover, first check the specified torque, and then

tighten each screw to the that torque. Also, make sure that no foreign

matter has entered the switch.

When mounting the cover, make sure that the cover and switch box

are properly aligned.
