ELECTRICAL INFORMATION
DOUBLE INSULATED
This grass trimmer has a plug that looks like the one shown in Fig. 1
The grass trimmer is double insulated to provide a double thickness of insulation between you and
the tool’s electrical system. All exposed metal parts are isolated from the internal metal motor
components with protective insulation.
TO AVOID ELECTRICAL HAZARDS, FIRE HAZARDS, OR DAMAGE TO THE
TOOL, USE PROPER CIRCUIT PROTECTION. YOUR GRASS TRIMMER IS
WIRED AT THE FACTROY FOR 120 V OPERATION. CONNECT TO A 120 V,
15 A CIRCUIT, AND USE A 15 A TIME-DELAYED FUSE OR CIRCUIT
BIREAKER. TO AVOID SHOCK OR FIRE, IF THE EXTENSION CORD IS
WORN, CUT OR DAMAGED IN ANY WAY, REPLACE IT IMMEDIATELY.
USE ONLY IDENTIFICAL REPLACEMENT PARTS WHEN SERVICING THE
GRASS TRIMMER, TO AVOID INJURY.
WARNING
DOUBLE INSULATION DOES NOT TAKE THE PLACE OF NORMAL SAFETY
PRECAUTIONS WHEN OPERATING THIS GRASS TRIMMER
WARNING
TO AVOID ELECTROCUTION:
1. Use only identical replacement parts when servicing a tool with double
insulation. Servicing should be performed by a qualified technician.
2. Do not use in wet or damp areas or expose to rain.
Fig. 1
CAUTION

ELECTRICAL INFORMATION
GUIDELINES FOR USING EXTENSION CORDS
USE THE PROPER EXTENSION CORD. 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 overheating. The table below 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.
GROUNDING INSTRUCTIONS
IN THE EVENT OF A MALFUNCTION OR BREAKDOWN, grounding provides the path of least
resistance for electric current, and reduces the risk of electric shock. This tool is equipped with a
POLARIZED plug. The plug MUST be plugged into a matching grounded extension cord in
accordance with All local codes and ordinances.
DO NOT MODIFY THE PLUG PROVIDED. If it will not fit the properly grounded extension cord,
have the proper outlet installed by a qualified electrician.

Make sure your extension cord is properly wired and in good electrical condition. Always replace a
damaged extension cord or have it repaired by a qualified person before use. Keep extension cords
away from sharp objects, excessive heat and damp or wet areas.
Use a separate electrical circuit for your tools. This circuit should comprise a wire of at least 12
gauge and should be protected with a 15 A time-delayed fuse. Before connecting the motor to the
power line, make sure the switch is in the OFF position and the electric current is identical to that
stamped on the motor nameplate. Running at a lower voltage will damage the motor.
