^ WARNING {
This unit is equipped with an internal combustion engine and should not be used on or near any unimproved forestcovered, brush-covered or grass-covered land unless the engine's exhaust system is equipped with a spark arrester
meeting applicable local or state laws (if any). If a spark arrester is used, it should be maintained in effective workin
order by the operator.
In the State of California the above is required by law (Section 4442 of the California Public Resources Code).
Other states may have similar laws. Federal laws apply on federal lands. A spark arrester muffler is available at
your nearest engine authorized service center.

IMPORTANT
SAFE OPERATION PRACTICES FOR POWER VACUUMS
1. Read this operating and service instructing manual
carefully. Be thoroughly familiar with the controls
and proper use of the power vacuum.
2. Never allow children to operate this power
vacuum.
3. Keep the area of operation clear of all persons,
particularly small children and pets.
4. No one should operate this unit while intoxicated
or while taking medication that impairs the senses
or reactions.
5. Check fuel before starting engine. Do not fill fuel
tank indoors, when engine is running, or while
engine is hot. Wipe off any spilled fuel before
starting engine.
6. Do not change engine governor settings.
7. Do not put hands near rotating parts for any
reasoh.
8. If the power vacuum should start to vibrate
abnormally, stop the engine and check immedi
ately for the cause. Vibration is generally a
warning of trouble.
9. Before cleaning, repairing or inspecting, make
certain all moving parts have come to a complete
stop. Disconnect spark plug wire and keep wire
away from plug to prevent accidental starting.
Also keep throttle control lever in the stop
position.
10. If the power vacuum should become blocked with
debris at any point, shut engine off and wait
until the impeller comes to a complete stop
before attempting to remove the obstruction.
Disconnect spark plug wire to prevent accidental
starting.
11. Check all bolts for tightness at frequent periods.
12. Never store this power vacuum with fuel in the
tank. Allow engine to cool before storing in any
enclosure.
13. Never operate this power vacuum unless air duct
and vacuum bag are properly affixed in their
place. Large zippered end of bag must be closed
when operating to prevent objects from being
blown out.
13. Keep bag and equipment free of debris when not
in use.
15. Never empty vacuum bag when engine is running.
16. Never change auxiliary hose attachment when
engine is running.
17. The manufacturer recommends that the operator
