Trouble Shooting - Troy-Bilt 566 Operator's Manual

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:
