NOTE:
Fuel stabilizer is an acceptable alternative to
emptying the tank of fuel in minimizing the formation of
fuel gum deposits during storage.
•
Add stabilizer to gasoline in fuel tank (on model 569
if FreshStart™ fuel preserver cartridge is empty) or
storage container.
•
Do not drain the gas tank and carburetor if using
fuel stabilizer.
In all cases, drain all the oil from the crankcase (this
should be done after the engine has been operated and
is still warm) and refill the crankcase with fresh oil.
When you visually see that the fuel preserver cartridge
is empty(model 569), replacement cartridges are
available through your local Troybilt Service Dealer.
If you do not use FreshStart™ or other fuel stabilizer,
follow these instructions:
•
Drain the fuel from the tank by running the engine
until the fuel tank is empty.
•
Remove spark plug, pour approximately 1/2 ounce
(approximately one tablespoon) of engine oil into
cylinder and crank slowly to distribute oil.
•
Replace spark plug.
•
Follow recommendations in the engine manual for
off-season storage of the engine.
•
Clean engine and remove any grass clippings.
Other
•
Do not store gasoline from one season to another.
•
Replace your gasoline can if it starts to rust. Rust
and/or dirt in the gasoline will cause problems.
Store unit in a clean, dry area. Do not store next to
corrosive materials, such as fertilizer.
NOTE:
If storing in an unventilated or metal storage
shed, be certain to rustproof the equipment by coating
with a light oil or silicone.
