23

TRANSPORTING

• Allow the engine to cool before transporting. 

• Secure the unit while transporting.

• Drain fuel from unit.

• Tighten fuel cap before transporting.

CLEANING

WARNING: 

To avoid serious personal injury,

always turn your trimmer off and allow it to
cool before you clean or do any maintenance
on it.

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 the unit with fuel in the tank 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 the unit will be stored for an extended time, use the
following storage procedure.

1. Drain all fuel from the fuel tank and drain 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 for any loose

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