ELECTRICAL SAFETY

d_IbWARNING: Avoid a dangerous environment. To reduce the risk of

electrical shock, do not use in rain, in damp or wet locations, or around swimming pools, hot tubs, etc. Do not expose to snow, rain, or water to avoid the possibility of electrical shock. Do not handle extension cord plug or unit with wet hands.

•Use only a voltage supply as shown on the nameplate of the unit.

•Avoid dangerous situations. Do not use in presence of flammable liquids or gases to avoid creating a fire or ex- plosion and/or causing damage to unit.

•Avoid dangerous environments. Do not use in unventilated areas or where dust or explosive vapors can build up.

•To reduce the risk of electrical shock, use extension cords specifically marked as suitable for outdoor ap- pliances. The electrical rating of the cord must not be less than the rating of the unit. The cord must be marked with the suffix "W-A" (in Canada, "W"). Make sure your extension cord is in good condition. Inspect extension cord before use and replace if dam- aged. An undersized extension cord will cause a drop in line voltage re- sulting in loss of power and over- heating. If in doubt, use the next heavier gauge. The smaller the _Naugenumber, the heavier the cord.

OTE: The correct size to be used

depending on the cord length is shown in this manual. See SELECT AN EXTENSION CORD in the AS- SEMBLY section).

•Inspect the insulation and connectors on the unit and extension cord before each use. If there is any damage, do

not use until damage is repaired by your Sears Service Center. Do not

pull or carry by cord; do not use cord as a handle, close a door on cord, or pull cord around sharp edges or cor- ners. Keep cord away from heated surfaces. Do not unplug by pulling on cord. To unplug, grasp the plug, not the cord.

•To reduce the possibility of the exten- sion cord disconnecting from the unit during operation, secure cord to cord retainer and connect to recessed plug as shown in this manual.

•Do not use the unit if the switch does not turn the unit on and off properly. Have the unit repaired by your Sears Service CenteE

•Keep the extension cord clear of oper- ator and obstacles at all times. Do not expose cords to heat, oil, water, or sharp edges.

•Avoid any body contact with any grounded conductor, such as metal fences, or pipes, to avoid the possibil- ity of electric shock. Don'thandle plug or unit with wet hands.

•Do not use with damaged cord or plug. If unit is not working as it should, has been dropped, dam- aged, left outdoors, or dropped into water, return it to your Sears Service Center for repair.

•Ground Fault Circuit Interrupter (GFCI) protection should be provided on the circuit or outlet to be used for this unit. Receptacles are available having built- in GFCI protection and may be used for this measure of safety.

•Keep others including children, ani- mals, bystanders, and helpers a mini- mum of 30 feet (10 meters) away. Stop the motor immediately if you are approached. Do not allow the unit to be used as a toy.

DOUBLE INSULATION

CONSTRUCTION

This unit is double insulated to help

protect against electric shock. Double insulation construction consists of two

separate "layers" of electrical insula- tion instead of grounding.

Tools and appliances built with a double insulation system are not in- tended to be grounded. No grounding means is provided on this unit, nor should a means of grounding be add- ed to this unit. As a result, the exten- sion 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 insulation

system only provides added protection against injury resulting from an internal electrical insulation failure.

_JkWARNING: All electrical repairs to this unit, including housing, switch, motor, etc., must be diagnosed and re- paired by qualified service personnel. Replacement parts for a double insu- lated 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 symbolFSq (square within a square) may also be marked on the appliance. Failure to have the unit re-
