Preparing the M-BUMP stacking platform

Required material
14 mm & 16 mm hex keys
Attach two M-JACK to each of the two M-BARs.
a. Remove both shackles from each M-BAR, keeping the safety pins and the bolts.
Refer to APPENDIX D for information about the safety pin mechanism.
b. At both ends of each M-BAR, align the M-JACK hole with the second M-BAR hole and secure with the bolt, nut
and safety pin previously removed from one of the shackles.
Attach both M-BAR/M-JACK assemblies to the M-BUMP.
a. Place an M-BUMP at the rigging location with the identification plate right side up
b. Remove both T-BLP from each M-BAR.
c. Place one M-BAR on each side of the M-BUMP frame, by inserting the M-BAR studs into the M-BUMP slits.
Choosing between the front or rear extension
At this step, install both M-BAR the same way, i.e. protruding at the front or the rear of the M-
BUMP, for front or rear extension respectively. The identification plate is the reference for the front
of the array, the laser slit being oriented towards the audience.
d. Secure the assembly by inserting the T-BLP previously removed from the two M-BAR.
Place the platform at the stacking location in the correct orientation with the M-JACK on the floor.
Adjust the heights of the four M-JACK to set the platform in perfect horizontal position.
a. Unscrew the locking nut on each M-JACK (16 mm hex key).
b. Place a handled inclinometer (included in the TECH TOOLCASE) on the platform, and rotate the 4 M-JACK
knobs to adjust the platform in the horizontal position.
Tips
In case of resistance when turning the knob, use a 14 mm hex key to turn the base nut
c. Lock each M-JACK height by firmly screwing the locking nut (16 mm hex key).
