Air Curtain Burner Instructions

Photograph Machine Before Using It

Your contract states you must take pictures of the machine when you receive it to record any damage you see when you take possession of it.

You will get an email that lets you easily take the exact photos needed and upload them to us. Please look for that email.

The photos ensure that you only pay for damage that you cause.

You are not responsible for scratches and paint damage. You are responsible for bending, cracking, crushing, melting, ripping and breaking any parts of the machine.

The main thing is to be careful with the manifold and the clutch. You are not responsible for belts and wear items.

You are responsible to check and maintain the oil and water levels. If you run it out of oil or do not keep water in it, then you will be responsible for the damage it causes. It does not leak oil or water.

Do not tow the machine over 62 MPH.

Set Up

Never locate the machine closer than 75′ to flammable materials or structures.

Make sure that there is clear access all around the machine to load fuel and remove ashes.

If you have any questions about building your pit or set up, in addition to reading all of this page, please contact us or visit:

How To Use An Air Curtain Burner

Starting the Machine

ALWAYS check weather for “no burn” orders and high wind. Rain or low clouds will hinder the machine’s performance and should be avoided.

DO NOT load the pit above the air curtain that is blowing across the pit.

NEVER put cardboard in the pit. NOTE: Only wood waste consisting of trees, logs, large brush, and stumps relatively free of soil may be burned.

Starting the Fire

If there are hot coals in the pit from prior operation, start the blower using the Engine Start Up Procedure (Outlined below). If not, pour one pint of diesel fuel or fuel oil (NOT gasoline, thinner, mineral spirits) on the wood in the front center of the pit and light the fire.

Once the fire is well lit, start the blower using the below Engine Start Up Procedure.

Never pour anything on the fire without checking with your local EPA/EPD office to see if accelerants are permitted.

ALWAYS make sure a fire extinguisher is on hand.


Burn Pit Loading Procedures

  • Once the fire reaches full intensity, intermittent loading may begin.
  • The intervals between loading may be determined by observing the burning rate.
  • The charges should be alternated between light and heavy material.
  • The material should be loaded toward the rear of the pit under the ACD manifold.
  • The pit should not be overloaded, that is, the material should not be piled up so high that it will protrude above the air curtain. This can damage the manifold causing you to have to buy a new one.
  • Loading several smaller loads instead of one large load when charging will enhance burner performance.

Engine Start-Up Procedure

It is advisable to call us before starting up the equipment so that no damage is incurred.

  1. Disengage the clutch lever.
  2. Push in Murphy switch and hold.
  3. Using the ignition switch, start the engine.
  4. Release Murphy switch after the oil pressure level has risen to proper operating level.
  5. Engage the clutch below 800 RPMS by bumping the clutch 3 to 5 times to get the fan spinning the slam the clutch in.
  6. Using the throttle adjustment knob increases engine speed to 2000 RPM.

Engine Shut-Down Procedure

  1. Stop loading the fire 60 minutes before you reduce engine speed to 800 RPM. After reducing RPMs
  2. Next disengage the clutch lever.
  3. Maintain 800 RPM for 10 minutes to allow the engine to cool.
  4. Switch the ignition key to the OFF position.

After Burning

Burn down the fire without adding any more debris 1 hour before turning off the burner or put dirt on it. This will keep the manifold from being exposed to super high heat without the cooling effect of the air blowing through it.

The machine must be returned as it was, as of the pick-up date or the delivery date.

Before you return the machine, you are responsible to take pictures of the machine to prove the condition when you return it. You will get an email that lets you easily take the exact photos needed and upload them to us. Please look for that email. The photos ensure that you only pay for damage that you cause.
