DOUBLE INSULATION CONSTRUC- TION
Your unit is double insulated to help protect against electric shock. Double insulation construction consists of two separate “lay- ers” of electrical insulation instead of grounding. Tools and appliances built with a double insulation system are not intended to be grounded. No grounding means is provided on this unit, nor should a means for grounding be added to this unit. As a re- sult, the extension cord used with your unit can be plugged into any standard 120 volt electrical outlet.
Safety precautions must be observed when operating any electrical tool. The double in- sulation system only provides added pro- tection against injury resulting from an inter- nal electrical insulation failure.
WARNING:
All electrical repairs to this unit, including housing, switch, motor, etc., must be diag- nosed and repaired by an authorized ser- vice dealer. Replacement parts for a double insulated appliance must be identical to the parts they replace. A double insulated appliance is marked with the words
“DOUBLE INSULATION” or “DOUBLE INSU- LATED.” The symbol (square within a
square) 
may also be marked on the ap- pliance. Failure to have the unit repaired by an authorized service dealer can cause the double insulation construction to become ineffective and result in serious injury.
UNIT/MAINTENANCE SAFETY
DDo not set the unit on any surface except a clean, hard area while the unit is run- ning. Debris such as gravel, sand, dust, grass, etc., could be picked up by the air intake and thrown out through the dis- charge opening, damaging the unit, prop- erty, or causing serious injury to bystand-
ers or operator.
D Do not overreach or use from unstable surfaces such as ladders, trees, steep slopes, rooftops, etc. Use extra care when cleaning on stairways. Keep firm footing and balance at all times. Keeps hands out of tubes.
DInspect the entire unit before each use for worn, loose, missing, or damaged parts. Do not use until the unit is in proper work- ing order.
D This unit is double insulated. See the
