MULCHING WITH THE BARK BLOWER
1. Check all areas listed under PRE-START EQUIPMENT CHECK.
2. Start the engine following all the steps listed under STARTING PROCEDURE.
3. Press the START button on the hardwired pendant to activate the MATERIAL START/
STOP feature on the remote. This will allow the material flow speed to be adjusted from
the remote.
4. Use the Radio Remote to stop material flow.
5. With material flow stopped, increase ENGINE RPM to full
6. With a firm grip on the hose, use the remote to start material flow.
7. Adjust floor speed and engine throttle to achieve desired amount of mulch output.
8. At the end of the load, push the MATERIAL STOP button on the hardwired pendant and
shut down the engine.
BARK BLOWER ADJUSTMENTS
The Bark Blower has been designed to be as simple as possible to operate. The feed roll and
rotary air valve are designed to create a smooth, consistent flow of material from the hopper to
the discharge hose. However, material conditions can change from one load to the next or from
one day to the next. Adjusting the floor speed and engine RPM will allow the Bark Blower to
efficiently convey many different types of materials.
Knowing when and how much to adjust the floor speed is the key to maximizing the machine’s
performance. The floor conveyor speed is controlled by the floor increase (FLOOR INC) or floor
decrease (FLOOR DEC) on the Keypad and/or Radio Remote. The floor speed can be increased
using these controls until certain warning signs appear. They include the following:
A. CONSISTENT HOSE SHOCK
The Bark Blower uses a large volume of air to blow the mulch material through the discharge
hose, which can, at times, become difficult for an operator to handle. Hose shock is usually due
to partial plugging around the rotary air valve discharge. When the material gets dislodged, the
larger clumps are shot through the hose and this action can make the hose jump significantly. If
rough shock waves become consistent, the floor speed can be turned down to smooth out the
flow of material into the rotary air valve. Increasing the engine RPM can also smooth out hose
shock by speeding up the air flow.
NOTE: Be careful not to lower the engine RPM too much, as this can cause
excessive plugging if there is not enough air to move the material or if the
material slows too much.
NOTE: Smooth application is a balance between air volume and material volume.
If hose shock is a problem, reduce the amount of material being fed into
the rotary air valve or increase air volume.
