Safety Rules and Instructions:

Extension Cords

WARNING:

shock, use only with an extension cord intended for

outdoor use, such as an extension cord of cord type

SW‑A, SOW‑A, STW‑A, STOW‑A, SJW‑A, SJOW‑A,

SJTW‑A. or SJTOW‑A.

Make sure your extension cord is in good condition. When

using an extension cord, be sure to use one heavy enough

to carry the current your product will draw. An undersized

cord will cause a drop in line voltage resulting in loss of

power and overheating. The table shows the correct size

to use depending on cord length and nameplate ampere

rating. If in doubt, use the next heavier gauge. The smaller

the gauge number, the heavier the cord. If the extension will

be used outside, the cord must be suitable for outdoor work.

The letters "WA" on the cord jacket indicate that the cord is

suitable for outdoor use.

Servicing of Double Insulated Appliances

Your appliance is double‑insulated to give you added

safety. In a double insulated appliance, two systems of

insulation are provided instead of grounding. No grounding

means is provided on a double insulated appliance, nor

should a means for grounding be added to the appliance.

Servicing a double insulated appliance requires extreme

care and knowledge of the system and should be done

only by qualified service personnel. 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 insulated or "double insulation". The

symbol (square within a square) may also be marked on

the appliance.

Safety Rules and Instructions:

Extension Cords

Double insulated appliances have 2‑wire cords and can

be used with 2‑wire or 3‑wire extension cords. Only

round jacketed extension cords should be used, and we

recommend that they be listed by Underwriters Laboratories

(U.L.) (C.S.A. in Canada). If the extension will be used outside,

the cord must be suitable for outdoor use. Any cord marked

as outdoor can also be used for indoor work.

Before using an extension cord, inspect it for loose or

exposed wires, damaged insulation, and defective fittings.

Make any needed repairs or replace the cord if necessary.

Safety Rules and Instructions:

Polarized Plug

To reduce the risk of electric shock, this appliance has a

polarized plug (one blade is wider than the other). This

equipment must be used with a suitable polarized 2 wire or

3 wire extension cord. Polarized connections will fit together

only one way. Make sure that the receptacle end of the

extension cord has large and small blade slot widths. If the

plug does not fit fully into the extension cord, reverse the

plug. If it still does not fit, obtain a suitable extension cord. If

the extension cord does not fit fully into the outlet, contact a

qualified electrician to install the proper outlet. Do not change

the appliance plug or extension cord in any way.

SAVE THESE INSTRUCTIONS

Motor

Be sure your power supply agrees with the nameplate

marking. Voltage decrease of more than 10% will cause loss

of power and overheating. These tools are factory tested; if

this tool does not operate, check power supply.
