SHUTDOWN

HOW TO BURN THE FIRE DOWN FOR SHUTDOWN
All loading should stop one or two hours before you intend to put the fire out.
As the fire burns down, maintain the air speed until the firebox begins to smoke. As
the smoke increases, reduce the air speed. This will help to reduce the smoke.
The air in the manifold needs air flow, both to accelerate the burn down and to protect
the manifold from warping due to excessive heat. DO NOT shut off the air flow, while
there are still flames within 24 inches of the manifold. Doing so may cause elevat-
ed temperatures to warp the manifold, nozzle assembly, etc. Your warranty does NOT
cover damage due to excessive heat.
Once the fire has burned down to about one or two feet and flames are not visible near
the manifold, it will be safe to shut the engine and air down. Make sure the fire is extin-
guished before you leave the job site. The best way is to load dirt or sand into the box,
but do not spray the refractory walls with water as this will damage them.
When the burning materials in the FireBox have burnt down to ash, reduce engine
RPM to 1400 RPM and disengage the PTO. Move the key switch to the OFF position
to shut down the engine. Never shut off the engine with the PTO still engaged. That
can cause damage to the drivetrain and is not covered under your warranty.
Some local authorities allow the firebox to be secured and the embers to smolder all
night. There is generally no smoke from this smoldering. Insure the work site is se-
cured or has a constant security guard to prevent any people or animals from getting
near the firebox. The inside temperatures of the firebox will remain very high most of
the night.
If you are not allowed to smolder through the night, then verify the fire inside is com-
pletely out. If it is still burning or smoldering you can either drag the firebox forward and
water down the embers or your can use sand or dirt to cover the remaining hot spots.
Ensure the fire is out and the job site secure before you leave.
DANGER:
Falling into the FireBox will cause serious injury or death.
