IMPORTANT
SAFE OPERATION PRACTICES FOR POWER VACUUMS
1. Read the 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 vac
uum.
3. Keep the area of operation clear or all persons,
particularly small children and pets.
4. 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.
5. Do not change engine governor settings.
6. Do not put hands near rotating parts for any rea
son.
7. If the power vacuum should start to vibrate ab
normally, stop the engine and check immediately
for the cause. Vibration is generally a warning of
trouble.
8. Before cleaning, repairing or inspecting make cer
tain 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 posi
tion.
9. 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 at
tempting to remove the obstruction. Disconnect
spark plug wire to prevent accidental starting.
10. Check all bolts for tightness at frequent periods.
11. Never store this power vacuum with fuel in the
tank. Allow engine to cool before starting in any
enclosure.
12. Keep bag and equipment free of debris when not
in use.
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.
14. Never empty vacuum bag when engine is running.
15. Never change inlet nozzle or auxiliary hose attach
ment when engine is running.
16. The manufacturer recommends that the operator
wear safety glasses or some other suitable eye
protection when operating this machine.
