5. When the engine starts, gradually back off the choke until the engine runs with no choke.
Operating
This machine has been designed for two methods of vacuuming debris:
1. With the handle of the intake nozzle in the operator’s hands, move the nozzle back and forth in a
sweeping motion over the debris.
2. Rotate the intake nozzle to lay sideways on the ground. By placing the nozzle in this position,
debris can be raked into the nozzle. While large amounts of debris can be vacuumed quickly with this
machine, caution must be taken to avoid blocking the airflow into the nozzle.
Stopping the Engine
When operation is complete, the unit needs to be checked, or a clog needs to be cleared:
1. Move the throttle to SLOW.
2. Set the engine switch to the OFF position.
3. Close the fuel valve.
Note: The impeller will continue to rotate for several seconds after engine is stopped.
Excessive Vibration
Shut off the engine immediately if abnormal/excessive vibration occurs. Remove the spark plug wire.
Find the cause of vibration and repair it. Some possible causes for excessive vibration are:
1. Damaged impeller.
2. Loose impeller bolt.
3. Loose impeller key.
4. Lodged objects.
Clogging
To prevent clogs, do not overfeed, especially with heavy wet material.
Pay attention to how full the debris receptacle is.
Overfilled debris receptacles cause material to back up and get tightly packed in the discharge
cute.
Removing Clogs
If a decrease in suction is experienced, there may be a debris blockage in the hose. Often a clogged
hose can be cleared by stretching the hose out straight with the engine running. If the hose does not
clear, you will need to remove the hose. Before removing the hose or attempting to clear a clog
manually:
1. STOP the engine. Put the engine switch in the OFF position.
2. Wait for the impeller to come to a complete stop.
3. Disconnect the spark plug wires so impeller movement cannot accidentally start the engine.
⚠CAUTION
Caution should be used when clearing truck loader from inside the housing.
Gloves should be worn as sharp edges on the impeller or in the truck loader maybe preset.
