MAINTENANCE AND REPAIR INSTRUCTIONS

CLEANING

Use a small brush to clean off the outside of the unit.
Do not use strong detergents. Household cleaners that
contain aromatic oils such as pine and lemon, and
solvents such as kerosene, can damage plastic housing
or handle. Wipe off any moisture with a soft cloth.

STORAGE

• Never store a fueled unit where fumes may reach an

open flame or spark.

• Allow the engine to cool before storing.

• Store the unit locked up to prevent unauthorized use

or damage.

• Store the unit in a dry, well-ventilated area.

• Store the unit out of the reach of children.

LONG TERM STORAGE

If you plan on storing the unit for an extended time, use
the following storage procedure:

1. Drain all fuel from the fuel tank into a container with

the same 2-cycle fuel mixture. Do not use fuel that
has been stored for more than 60 days. Dispose of
the old fuel/oil mix in accordance to Federal, State
and Local regulations.

2. Start the engine and allow it to run until it stalls. This

ensures that all fuel has been drained from the
carburetor.

3. Allow the engine to cool. Remove the spark plug and

put 1 oz. (30 ml) of any high quality motor oil or
2-cycle oil into the cylinder. Pull the starter rope
slowly to distribute the oil. Reinstall the spark plug.

NOTE: Remove the spark plug and drain all of the oil

from the cylinder before attempting to start the
trimmer after storage.

4. Thoroughly clean the unit and inspect it for any loose

or damaged parts. Repair or replace damaged parts
and tighten loose screws, nuts or bolts. The unit is
ready for storage.

TRANSPORTING

• Allow the engine to cool before transporting.

• Drain fuel from unit.

• Tighten fuel cap before transporting.

• Secure the unit while transporting.

WARNING: To avoid serious personal injury,
always turn your trimmer off and allow it to
cool before you clean or service it.
