Poulan 952802075 Helpful Tip, Spark Plug, Cooling System, Seasonal Storage, Fuel System

SPARK PLUG

The spark plug should be replaced each year to ensure the engine starts easier and runs better. Ignition timing is fixed and non- adjustable.

NOTE: This spark ignition system complies with the Canadian standard ICES--002.

1.Loosen 3 screws on cylinder cover.

2.Remove the cylinder cover.

3.Pull off the spark plug boot.

4.Remove spark plug from cylinder and discard.

5.Replace with Champion RCJ--7Y spark plug and tighten with a 3/4 inch socket wrench. Tighten securely. Spark plug gap should be 0.025 inches.

COOLING SYSTEM

To keep the working temperature as low as possible the machine is equipped with a cooling system.

The cooling system consists of:

SAir intake on the starter S Air guide plate

S Fins on the flywheel

S Cooling fins on the cylinder

S Cylinder cover (directs cold air over the cylinder)

Clean the cooling system with a brush after each use, more often in demanding condi- tions. A dirty or blocked cooling system re- sults in the machine overheating which causes damage to the piston and cylinder.

STORAGE

WARNING: Perform the following steps after each use:

SAllow the engine to cool, and secure the unit before storing or transporting.

SStore chain saw and fuel in a well venti- lated area where fuel vapors cannot reach sparks or open flames from water heaters,

electric motors or switches, furnaces, etc.

SStore chain saw with all guards in place and position chain saw so that any sharp

object cannot accidentally cause injury.

SStore chain saw well out of the reach of children.

SEASONAL STORAGE

Prepare your unit for storage at the end of the season or if it will not be used for 30 days or more.

If your chain saw is to be stored for a period of time:

SClean saw thoroughly before storage. S Store in a clean dry area.

S Lightly oil external metal surfaces and guide bar.

S Oil the chain and wrap it in heavy paper or cloth.

FUEL SYSTEM

Under FUELING ENGINE in the OPERA- TION section of this manual, see message labeled IMPORTANT regarding the use of gasohol in your chain saw.

Fuel stabilizer is an acceptable alternative in minimizing the formation of fuel gum depos- its during storage. Add stabilizer to the gaso- line in the fuel tank or fuel storage container. Follow the mix instructions found on stabiliz- er containers. Run engine at least 5 minutes after adding stabilizer.

Poulan/WEED EATER 40:1, 2-cycle engine oil (air cooled) is blended with fuel stabilizer. If you do not use this oil, you can add a fuel stabilizer to your fuel tank.

HELPFUL TIP

During storage of your gas/ oil mixture, the oil will sepa- rate from the gas.

We recommend that you shake the gas can weekly to insure proper blending of the gas and oil.

ENGINE

SRemove spark plug and pour 1 teaspoon of 40:1, 2-cycle engine oil (air cooled) through the spark plug opening. Slowly pull the starter rope 8 to 10 times to distrib-

ute oil.

SReplace spark plug with new one of rec-

ommended type and heat range.

SClean air filter.

SCheck entire unit for loose screws, nuts,

and bolts. Replace any damaged, broken, or worn parts.

SAt the beginning of the next season, use only fresh fuel having the proper gasoline to oil ratio.

OTHER

SDo not store gasoline from one season to

another.

S Replace your gasoline can if it starts to rust.
