INTRODUCTION

THE FINN BARK BLOWER AND ITS FUNCTION
The FINN Bark Blower is an apparatus for conveying and discharging bulk materials, such as
bark mulch, at a fast and uniform rate utilizing a minimum amount of manpower. The product to
be used is generally composted and processed, then used as a soil amendment, a ground cover
for erosion and weed control, or for decorative purposes on landscaping (bark mulch).
This manual is intended to provide step-by-step instructions on the operation, care, and
maintenance of the Bark Blower. In addition, it contains illustrations and a complete list of parts
and components for easy identification.
HOW THE BARK BLOWER WORKS
The bulk material is loaded into the hopper by a loader or by a feed elevator. Located at the
bottom of the hopper is a drag chain conveyor that conveys the bulk material to an opening, in
the rear of the hopper, containing a feed roll. The feed roll and drag chain conveyor feed the bulk
material into an airlock. The airlock is specifically designed and built to handle tough, fibrous
material. The function of the airlock is to take the bulk material into open pockets exposed to the
outside air and to convey it to an area where the pocket is closed off. At that point a high volume /
low pressure air stream, created by the blower, is channeled through the pocket, carrying the
material out of the airlock and through the hose for discharge.
For best results and to ensure safe operation and long life of the
equipment, please read and follow all instructions carefully.
TOWING VEHICLE
The truck used to tow the FINN 5-Series must be equipped with a 2-5/16 in. ball-type or pintle-
type hitch. This hitch should be mounted as near to the end of the truck bed as possible. The
tow vehicle should be fully wired for trailer marker, turn, and stop lights, as well as electric
brakes, and be sized to be able to pull and stop a 12,585 lbs. (5,708 kg) trailer. (Loaded 5-Series
assuming 750 lbs./yd.

mulch.)
NOTE: When towing tandem axle unit, always ensure the unit is level,
applying equal weight distribution across both axles.
When mounting a skid 5-Series, be sure to follow the 5-Series skid-
mounting instructions. Ensure proper weight distribution and make
sure the Bark Blower is properly supported by the truck. When mounting a skid model,
contact FINN Corporation for proper instructions. Failure to comply could result in minor or
moderate personal injury. Failure to comply could also result in product or property damage.
