SELECTING A MULCHING MATERIAL:
Several factors must be considered when selecting material to convey through the Bark Blower. The variety
of the wood used, how it is processed, its moisture content, and the presence of foreign objects all effect the
ability of the Bark Blower to convey the mulch at a uniform and acceptable rate.
The mulch material must be processed and/or screened so that a minimum of material is over 2 inches (5.1
cm) in any direction with no material exceeding 4 inches (10.2 cm) in length. The Bark Blower is not a
wood processor. It only reduces mulch fibers when they protrude above the rotary air valve (airlock) vanes.
As the vanes rotate past the knife, the protruding fibers are sheared off. If the mulch contains long or large
fibers, and if the wood fibers are harder to cut, then the machine’s throughput is reduced. For example, if
two mulches have the same mix of material sizes that the Bark Blower rotor must cut, but one is softwood
like pine, and one is hardwood such as oak, the pine would go through at a higher rate because it is easier
to cut.
Two characteristics must be considered when selecting a material: the “greenness” of the wood and the
moisture of the mulch as a whole. Wood that is well seasoned is easier to cut than “green” wood. It also
processes better, making a less stringy mulch. High moisture in the mulch may cause it to bridge in the
hopper.
CAUTION: Avoid using mulches that contain any hard foriegn objects
such as dirt, mud, rocks, nails, glass metalic objects, etc.
These objects could cause bodily injury as well as damage
to machine components, especially the cutting knifes in the
airlock. If you have any questions regarding the materials that
can be used, contact your sales rep.
PRE-START EQUIPMENT CHECK:
CAUTION: Equipment check is made with the engine off and all rotating
parts stopped.
Safety check to insure operator safety:
1. Check that all the truck mountings are secure.
2. Make sure that all guards are in place.
3. Tool Kit - see that it contains all prescribed items (see tool kit list, parts manual).
4. Lubricate equipment - use handgun only (see lube chart, pages 28-29).
5. Check engine oil - refer to engine operator’s manual.
6. Check liquid coolant level in radiator (protected to -34ºF (-37ºC) when shipped).
7. Check fuel level. Use #2-D diesel fuel oil unless operating at ambient temperature below 40ºF (4ºC)
or at an altitude exceeding 5000 feet (1524 meters). In these instances use #1-D fuel oil.
8. Inspect the engine air cleaner (refer to the engine operator’s manual), the radiator chaff screen, and
the blower air cleaner for dust and dirt.
9. Check hopper and transition for foreign objects that could injure workers, or damage equipment.
10. Check the fluid level in the hydraulic tank. Check that service valve is open on reservoir. Proper
level is midway between the upper and lower indicator mark on the sight gauge. (See page 29 for
oil specification).
11. Install the discharge hose, using the short hot air hose section as the first connection after the airlock.
This will help extend the life of the other hoses. Use clamps provided with the machine.
