ON/STOP SWITCH

The ON/STOP SWITCH is used to stop the engine.

THROTTLE TRIGGER

The THROTTLE TRIGGER controls engine speed.

THROTTLE LOCK---OUT

The THROTTLE LOCK--OUT must be pressed before you can squeeze the throttle trigger. This feature prevents you from acci- dentally squeezing the trigger.

CHOKE/FAST IDLE LEVER

The choke and fast idle speed are set by pull- ing the CHOKE/FAST IDLE LEVER out fully for cold or for refueled starting. The choke provides additional fuel to the engine during cold starting.

CHAIN BRAKE

The CHAIN BRAKE is a device designed to stop the chain if kickback occurs. The chain brake activates automatically in the event of kickback. The chain brake activates manu- ally if the front hand guard is pushed forward. The chain brake is disengaged by pulling the front hand guard back toward the front han- dle as far as possible.

CHAIN TENSION

It is normal for a new chain to stretch during first 30 minutes of operation. You should check your chain tension frequently. See CHAIN TENSION in the ASSEMBLY sec- tion.

WARNING: Muffler is very hot dur- ing and after use. Do not touch the muffler or allow combustible material such as dry grass or fuel to do so.

FUELING & LUBRICATION

FUELING ENGINE

WARNING: Remove fuel cap slow- ly when refueling.

HELPFUL TIP

To obtain the correct oil mix ratio, pour 3.2 ounces of 2-cycle synthetic oil into one gallon of fresh gas.

This engine is certified to operate on unleaded gasoline. Before operation, gasoline must be mixed with a good quality synthetic 2-cycle air-cooled engine oil designed to be mixed at a ratio of 40:1. Poulan/WEED EATER brand synthetic oil is recommended. Mix gasoline and oil at a ratio of 40:1. A 40:1 ratio is obtained by mixing 3.2 ounces of oil with 1 gallon of unleaded gasoline. Included with this saw is a

3.2ounce container of oil. Pour the entire contents of this container into 1 gallon of gasoline to achieve the proper fuel mixture. DO NOT USE automotive oil or boat oil. These oils will cause engine damage. When mixing fuel, follow instructions printed on container. Once oil is added to gasoline, shake container momentarily to assure that the fuel is thoroughly mixed. Always read and follow the safety rules relating to fuel before fueling your unit.

BAR AND CHAIN LUBRICATION

The bar and chain require continuous lubri- cation. Lubrication is provided by the auto- matic oiler system when the oil tank is kept filled. Lack of oil will quickly ruin the bar and chain. Too little oil will cause overheating shown by smoke coming from the chain and/ or discoloration of the bar.

In freezing weather oil will thicken, making it necessary to thin bar and chain oil with a small amount (5 to 10%) of #1 Diesel Fuel or kerosene. Bar and chain oil must be free flowing for the oil system to pump enough oil for adequate lubrication.

Genuine Poulan or Poulan PRO bar and chain oil is recommended to protect your unit against excessive wear from heat and

friction. Poulan or Poulan PRO

oil resists

high temperature thinning. If

Poulan or

Poulan PRO bar and chain oil is not available, use a good grade SAE 30 oil.

SNever use waste oil for bar and chain lubri- cation.

SAlways stop the engine before removing the oil cap.

IMPORTANT

Experience indicates that alcohol--blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, the fuel system should be emptied before storage for 30 days or longer. Drain the gas tank, start the engine and let it run until the fuel lines and carburetor are empty. Use fresh fuel next season. See STORAGE section for addi- tional information.
