5.5.2. Removing the Z1 Actuator
Step 1 – Before removing the Z1 actuator, make sure
the head is all the way down against the bottom hard
stops. Disconnect power from the ALS 4.0 and lockout/
tag out the machine. Now unplug power and feedback
cables from the top of the actuator.
!
CAUTION
Failure to disconnect the power from the machine before
removing the cables is not only dangerous, it WILL damage the
actuator.
Step 2 – Start removing the actuator by releasing the
rod end that is attached to the Z-axis slide. Remove the
four socket head cap screws from the bottom of the
casting using an 8mm Allen wrench as shown in the
Figure 174.

Step 3 – With the rod end of the actuator free remove
the right-hand roof panel. Use a 5/32” Allen wrench to
remove the 11 cap screws around the perimeter of the
roof panel and a 7/16” at wrench to remove the ve
hex head screws that attach the right-hand panel to
the middle panel. Set the removed panel aside. This will
provide the necessary clearance for the Z1 actuator to
be removed through the top of the saw cabinet.
Step 4 – Use an 8mm Allen wrench to remove the
cap screws from the trunnion mount at the top of the
actuator. Carefully lift the actuator up and remove it
through the top of the machine. The location of the cap
screws and trunnion are shown in Figure 175.
