CAUTION: Do not use radiator type clamps. These clamps may not hold
under machine operating pressure.
STARTING PROCEDURE:
CAUTION: See safety section of the manual (pages 2-4) before operating
the machine.
1. Turn the remote control to the off position on the remote control panel.
2. Turn the key until starter engages and the engine fires.
NOTE: This engine has a safety system that will shut the engine off if the
engine oil pressure drops below 7 PSI (.48 bar) or if the water tem-
perature reaches 230º Fahrenheit (110º Centigrade).
3. Allow engine to warm up for three to five minutes.
4. Prior to mulch application, move the throttle position to fully open, and allow the governor to con-
trol the engine speed. Governed engine speed should be 2575 to 2625 RPM under load.
CREW MEMBERS AND THEIR DUTIES:
1. The Operator controls the placement of the mulch by moving and aiming the discharge hose.
2. The Loader(s) feed material to the machine by using a bucket loader or belt conveyor dumping
material directly into the hopper.
THE MATERIAL FEED SYSTEM:
The material feed system on the Bark Blower has been designed to give fast and uniform mechanical feed-
ing. The adjustable feeding rate and the automatic reverse control system allow the use of varied materials
while obtaining maximum production. The system is an integration of the following four subsystems, all of
which contribute to efficient material flow:
SUBSYSTEM 1: MATERIAL HANDLING GROUP
The four major components of the material handling group are the blower, the drag conveyor, the feed roll,
and the rotary air valve (airlock).
The blower is a rotary lobe, positive displacement type unit having two double lobe impellers. It is direct
driven off the engine flywheel by a flexible coupling. Therefore, whenever the engine is running, air is
being pumped. The blower is equipped with a relief valve limiting maximum air pressure to 16 PSI (1.1
bar), an inlet and outlet silencer for noise attenuation, and an inlet air filter.
The drag conveyor receives material from the agitated hopper and conveys it to an opening located at the
rear of the hopper, where the feed roll is located. The feed roll insures a uniform feed of bulk material to
the rotary air valve. The drag conveyor is powered by a variable speed hydraulic motor mounted to a gear-
box.
