Gantry Brake - Acer Wood Runner Manual

4.7 Gantry Brake

Never attempt to operate the Wood Runner system unless the Gantry brake system is operational and has been
tested for safe operation. Never remove or disable the brake system. Serious machine damage, injury or death
may occur.
Cut and remove the zip tie strap or shrink wrap holding the Gantry Brake plunger onto the Gantry. There will be
a slight amount of spring pressure.
The brake release tool is pre-installed in the rear brake chamber for shipping and must be removed to allow the
gantry brake to operate.
To remove, turn the hex nut counter-clockwise using a 3/4" wrench. Remove the nuts and washer. Now remove
the threaded release tool stud by rotating it ¼ turn to the counterclockwise to unlock it. There will be a slight
resistance. Remove the tool from the hole, insert the release tool into the mounting hole on the outside of the
brake chamber and fasten in place with the washer and nuts.
Note: Once this is done, the Gantry cannot be moved until the wiring and pneumatics are functional.
