Why does my footswitch have air blowing out of it when I am not stepping on it?

The problem lies in the Foot Pedal Actuator; here are three things you can check:

  1. It could be the (valve in-side the foot pedal housing) that is causing the problem. This occurs when the actuator has become loose and is misaligned allowing the top portion of the pedal's tab to depress the actuator shaft (button) causing the valve to be a portion of the way depressed (open) allowing air the continue to flow through the pedal.
  2. It may also be that the actuator did not completely open (spring back) after you last stepped off the foot pedal.
  3. There could also be some dust / debris keeping the valve from completely opening (once your foot is off the pedal).
    Simple Fix:
    • Realign foot pedal actuator
    • Clean / lubricate existing actuator with WD40 to remove any dust or derbies from actuator shaft, or within the actuator, blow away any dust from the actuator shaft (button), possibly lubricate shaft, or replace the foot pedal and hoses.
    • To access the actuator remove the two screws on the sides of the pedal.
    • Remove BLUE supply hose and RED exhaust hose for internal lubrication and cleaning.
    • Replace the foot pedal and hoses your cost will be $115.00 (price includes a new modified actuator), unfortunately your style may have been discontinued which will require an up-grade.

Tips:

When removing the screw sleeves from your actuator; Keep a watchful eye for the screws and the foot pedal spring that retracts the pedal, they are very small items and easy to loose.

I can't get the air to stop coming out my hose. The foot pedal has no control. I have taken apart my entire assembly at the bottom of the pot, replaced the white block along with the rubber diaphragm.

This could only be caused by two possible problems:

   1. Air-supply. The Pressure Pot requires at least 80psi supplied to the pot for the diaphragm to stop the flow of air and sand through the white valve body (lower media valve). The upper media valve requires a minimum 30psi greater pressure then your blasting pressure (shown on pot's regulator). The upper media valve receives the unregulated air-supply from the compressor. Confirm your Air Compressor is set at the maximum air-output there should be no air restriction to the pot.
   2. Foot Pedal Actuator. There is an actuator located in your foot pedal housing that interrupts the air supply when stepping on the pedal. When the pedal is not being depressed it is "normally open" meaning the air is flowing through it. Once you step on the pedal it allows the built up pressure in the lower media valve to force the diaphragm open and the sand and air to flow through the lower media valve and the blasting hose. If your sand and air is not stopping, possibly the foot pedal actuator is stuck closed or pressed in and will not spring back out. Open the foot pedal housing and confirm the actuator tab springs in and out when pressing the tab.

Does the exhaust vent on the 2034VX and 2648VX need to be vented outside?

No, the exhaust vent on the dust collector does not need to be vented outside; the dust collector does a superb job of collecting the dust and exhausting clear air. However, it is optional to install some flex tubing and exhaust to an outside wall.

Will the 2034VX Sandcarving Systems fit through my shop door?

The 2034VX Sandcarving System will fit through any standard size 36" door. If you have a smaller door entry, as an option, you can remove the padded arm rests; this will reduce the width of the sandcarving system to about 32" allowing for an easier entrance.
