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 for-
eign objects all affect the ability of the Bark Blower to convey the mulch at a uniform and accept-
able rate.
The mulch material must be processed and/or screened, so that a minimum of material is over
2 in. (5.1 cm) in any direction, with no material exceeding 4 in. (10.2 cm) in length. The Bark
Blower is not a wood processor. The Bark Blower only reduces mulch fibers when they protrude
above the airlock vanes. As the vanes rotate past the knife, the protruding fibers are sheared off.
If the mulch contains long or large fibers and 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 a softwood like pine and one is a 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. Seasoned wood 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 foreign objects, such as rocks, nails, steel, cans,
glass, etc. Failure to comply could result in minor to moderate personal injury. Failure to
comply could also result in product or property damage.
PRE-START EQUIPMENT CHECK
CAUTION
Equipment check must be made with the engine off and all rotating parts stopped. Failure
to comply could result in minor to moderate personal injury. Failure to comply could also
result in product or property damage.
Safety check to ensure operator safety:
1. Check that all the truck mountings are secure.
2. Ensure that all guards are in place.
3. Tool Kit - make sure that it contains all prescribed items (see tool kit list in the
Parts Manual).
4. Lubricate equipment. Use handgun only (see Lubrication Chart, pages 32 and 33.
5. Check engine oil and fill or change if necessary. Refer to Engine Operator’s Manual.
6. Check liquid coolant level in radiator and fill or replace if necessary (protected to
-34ºF [-37ºC] when shipped).
7. Check fuel level. Use number 2-D diesel fuel oil, unless operating at ambient
temperature below 40ºF (4ºC) or at an altitude exceeding 5,000 ft (1,524 m).
In these instances, use number 1-D diesel fuel oil.
