SAFE OPERATION PRACTICES FOR POWER VACUUMS

Read this operating and service instructing manual

carefully. Be thoroughly familiar with the controls and proper use of the power vacuum.

. Never allow children to operate this power

vaccum.

. Keep the area of operation clear of all persons,

particularly small children and pets.

. 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.

Do not change engine governor settings.

. Do not put hands near rotating parts for any

reason.

. 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.

. 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.

. 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.

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 storing 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.

17. Check the vacuum bag frequently for wear and replace when necessary.

18. Never operate as a leaf blower unless impeller guard and guard assembly are properly affixed in their place.

19. Exercise caution whenever operating as a leaf

blower. Do Not allow discharge to be pointed in
