servicing your boom arm
Your Mullet Boom Arm is designed to make an endless amount of
memories. But there are a couple of components that can wear over time.
O RINGS
Worn O Rings can crack or compress over extended use compromising
easy rotation. Find replacements at mullettools.com.
TEFLON WASHERS*
Careful not to lose these little buggers when disassembling your Pivots,
as the Tee Knobs may not hold in place. But no sweat if you do – more can
be found at mullettools.com, along with virtually every other component.
Square O-Ring (#133) 2x
Molded Bushing
Carriage Bolt (1/4-20)

*Note: Without Teon washer Tee Knob may tighten or loosen when rotating.

troubleshooting
1) Pipe pulls out of pivot.
That’s intended so that you can modify the setup for your shop. But if you
want to lock it more permanently in place, use the included Self-Drilling
Screws to attach Pivots, Dust Hood or Hose Adapter to pipe or Cyclone
inlet.
2) Pivot is rotating on cyclone inlet.
Ensure the Pivot is rmly pushed into the Cyclone inlet. You can also use
an included Self-Drilling Screw to more permanently lock it in place.
3) My vac has an angled inlet when attaching the base.
No sweat. It’s rare, but Gus can get you a free 3D-printed adapter to get
you connected lickity split. Get in touch with [email protected].
4) The base interferes with my shop vac or dust extractor's wheels.
Ensure the base is centered relative to your vac and its inlet. If it still
interferes, move the base forward (away from your vac) by moving the
rear casters to the alternate set of holes and moving the PVC Table Mount
back towards the rear of the base.
5) My hose doesn’t t into the tee on my workbench.
Gus can help solve this problem, too. Hit him up at [email protected].
Just don’t ask for tax advice.
