4.0 OPERATIONS
4.1 TO THE NEW OPERATOR OR OWNER
Buffalo Turbine Debris Blowers are designed to quickly and efficiently, blow away leaves, cuttings and other debris. The material is
conveyed on a stream of high volume and velocity of air to remove it from the area of concern. When the material is removed, it gives a
neat, professional look to the working area.
Many of the features incorporated into the machine are the result of suggestions made by customers like you. Read the manual carefully to
learn to operate the machine safely and how to set it to provide maximum efficiency. The manual will take you step-by-step through your

4.5 FIELD OPERATION
1. Do not direct debris blower towards people, pets, autos, windows, etc.
2. Starting blower unit: Always start engine at a lower engine speed with nozzle pointed down or away.
3. The air stream direction is changed (in either direction) by pressing the nozzle buttons on the transmitter. The nozzle will stop
turning by releasing the transmitter button. ALWAYS CHECK THE GROUND CLEARANCE WHEN OPERATING THE NOZZLE
IN THE DOWN VERTICAL POSITION.
4. Stopping blower unit: Shut engine off above ½ throttle by turning key switch to off position to avoid engine backfire.
5. Allow the blower fan speed to come to a complete stop before disconnecting from tow vehicle.
4.6 Operating RPM (All Models)
The manufacturer’s engine section normally recommends the unit be run at a RPM that will insure efficient operation. The
Blower can operate at a slower RPM if it can effectively move the debris. Increase engine RPM as needed.
Moving light material, such as dry leaves, requires much less wind than wet or heavier material.
Always try to blow with the wind. The Blower can be used for a wide variety of applications to move leaves, grass clippings,
aeration plugs and debris. Drying wet areas has been another use with these powerful Debris Blowers.
4.7 Storage
At the end of the working season or before storing the blower unit, prepare the machine by following this procedure:
1. Select a storage area that is dry, level and free of debris.
2. Thoroughly wash the machine with a water hose to remove all debris and residue.
3. Run the machine at low RPM to dry the Blower Components.
4. Touch up all paint chips and scratches to prevent rusting.
5. Inspect for worn or failed components. Order the replacement parts and repair the blower unit when time allows. This will
eliminate unnecessary down time at the start of next season.
6. Store in an enclosed building. If space is not available, cover with a waterproof tarpaulin and tie it down securely.
7. Store the machine away from areas of human activity.
8. Do not allow children to play around the stored unit.
5.0 TROUBLE SHOOTING
The Buffalo Turbine Debris Blower uses a high volume and velocity of air to move material from one place to another. The
