vacuum.
OPERATION4.4
This yard vacuum has been designed to pick up dry
organic debris such as leaves, grass clippings, shavings
and saw dust as well as debris mixed with cans, bottles
and small amounts of sand. Vacuuming hard non-organic
material will affect the life of your machine. Sand is
abrasive and will produce wear of items including the
blower housing, impeller and bag adapter.
WARNING
DO NOT operate the machine without the entire
debris bag and bag adapter installed and the
zipper fully closed. Always wear eye, ear and
breathing protection when operating machine.
Adjust the height of the vacuum inlet. For maximum1.
debris pickup, the inlet should be as close to the
debris as possible without blocking airflow and the
engine speed should be set to "Fast".
Inspect the debris bag. It must be properly attached2.
to the machine, in good condition, clean and dry
with the top zipper fully closed. Make sure that the
accessory plug is installed into the front hole in the
vacuum nozzle.
Not all debris pick up will require that the engine3.
speed be set to "Fast". You can experiment with the
vacuum inlet height and engine speed to best suit
your conditions.
Operating in dry dusty conditions may require that4.
the engine speed be set to the "Slow" position. The
debris bag can quickly become plugged with fine
dust reducing vacuum action. A zippered vent flap
has been provided on the side of the debris bag.
It can be opened to improve air flow. Do not open
when the engine is running.
For peak performance, keep the debris bag clean5.
and do not overfill. The bag must be completely dry
before use.
