If the tiller will not be used for a period longer
than 30 days, following the steps below to
prepare your tiller for storage.
1. Drain the fuel tank completely. Stored fuel
containing ethanol or MTBE can start to go
stale in 30 days. Stale fuel has a high gum
content and can clog the carburetor and
restrict fuel flow.
2. Start the engine and allow it to run until it
stops.
This ensures no fuel is left in the carburetor.
This helps prevent gum deposits from forming
inside the carburetor and possible engine
damage.
3. While the engine is still warm, drain the oil
from the engine. Refill with fresh oil of the
grade recommended in the Engine Manual.
4. Allow the engine to cool. Remove the spark
plug and put 30 ml (1 oz.) of high quality motor
oil into the cylinder. Pull the starter rope slowly
to distribute the oil. Replace the spark plug.
Remove the spark plug
and drain all of
the oil from the cylinder
before attempting to
start the unit after
storage.
5. Use clean cloths to clean off the outside of
the tiller and to keep the air vents free of
obstructions.
Do not use strong
detergents or petroleum
based cleaners when
cleaning plastic parts.
Chemicals can damage
plastics.
6. Inspect for any loose or damaged parts.
Repair or replace damaged parts and tighten
loose screws, nuts or bolts.
7. Remove the tines. Clean and apply oil to the
tines and tine shafts to prevent rusting. Mount
the tines onto the tine shafts.
8. Oil the control cables and all visible moving
parts. Do not remove the engine cover.
9. To store with the handles folded down,
loosen the knobs that secure the upper handle
STORAGE
to the lower handles. Carefully fold the upper
handle down. Do not allow control cables to
become pinched or bent. Tighten the knobs.
Do not sore tiller with
fuel in a non-ventilated
area where fuel fumes
may reach flame,
sparks, or any ignition
sources.
Use only approved fuel
containers.
