SEASONAL
STORAGE
Prepare unit for storage at end of season or if it will not be used
for 30 days or more. If your unit is to be stored for a period
of time:
• Drain all fuel from the fuel tank into the proper receptacles
for storage.
• Press purge bulb 15 times to remove all fuel from carburetor
and fuel lines. Drain this fuel into proper receptacles. If fuel is
to be disposed, please refer to local rules for proper disposal.
• Clean the entire unit before lengthy storage.
• Store in a clean dry area.
• Lightly oil external metal surfaces.
• This trimmer may be stored in a variety of positions. If
possible, it is preferred to store the trimmer in a horizontal
position with the spark plug up. The trimmer should not be
stored or transported
with the spark plug down.
• Storing or transporting the trimmer with the spark plug down
may result in white smoke coming from the muffler or
difficulty starting.
ENGINE
• Remove spark plug and pour 1 teaspoon of HD30 wt. engine
oil through the spark plug opening. Slowly pull the starter rope
8 to 10 times to distribute oil.
• Replace spark plug with new one of recommended
type and
heat range.
• Clean air filter.
• Check entire unit for loose screws, nuts, and bolts. Replace
any damaged, broken, or worn parts.
• At the beginning of the next season, use only fresh fuel.
OTHER
• Do not store gasoline from one season to another.
• Replace your gasoline can if it starts to rust.
• When removing the unit from storage, only use fresh gasoline.
Perform the routine operation checks as spelled out in the
manual before any start.
FUEL SYSTEM

formation
of fuel gum deposits during storage. Add stabilizer to
the gasoline in the fuel tank or fuel storage container. Follow the
mix instructions
found on stabilizer container. Run engine at
least 5 minutes after adding stabilizer.
