ELECTRICAL INFORMATION
DOUBLE INSULATED
This grass trimmer has a plug. 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 FACTORY FOR 120V OPERATION. CONNECT TO A 120 V,
15 A CIRCUIT, AND USE A 15 A TIME-DELAYED FUSE OR CIRCUIT
BREAKER. TO AVOID SHOCK OR FIRE, IF THE EXTENSION CORD IS
WORN, CUT OR DAMAGED IN ANY WAY, REPLACE IT IMMEDIATELY.
USE ONLY IDENTICAL 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.
CAUTION
ALWAYS MAKE SURE THAT YOUR OUTLET IS PROPERLY GROUNDED.
IF UNCERTAIN, HAVE IT CHECKED BY A CERTIFIED ELECTRICIAN.
WARNING
THIS GRASS TRIMMER IS FOR OUTDOOR USE ONLY. DO NOT EXPOSE
TO RAIN OR USE IN DAMP LOCATIONS.

ELECTRICAL INFORMATION
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.
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.

TRIMMING
1. Hold the grass trimmer. Gently swing the trimmer from side
to side (Fig. 10).
2. When cutting long grass, work in stages from top to bottom
in small sections. This will prevent the grass being cut from
wrapping around the shaft and spool head.
3. If the grass trimmer starts running slowly, reduce the load.

NOTE: This trimmer is equipped with a 7-position pivoting head. The head can be adjusted so it is
easy to access to areas such as under bushes and garden furniture.
1. Depress the pivoting head button and adjust the shaft to the desired angle (Fig. 11).
2. Release the button.
USING THE FLOWER GUARD
If necessary the flower guard can be swung down until it engages. Use the flower guard as shown
to cut around delicate plants or flowers (Fig. 12).

trimmer. The line will extend approximately 3/16” with each stop and start of
the on/off switch WHILE NOT TRIMMING until the line reaches the length of
the grass deflector blade.
3. It may take up to 10 complete starts and stops to advance the line.
NOTE: After each use, clean the trimmer head with a damp cloth to remove
dirt and grime.
