CHAIN TENSION (Including units with chain already installed)

NOTE: When adjusting chain tension, make sure the bar nuts are finger tight only. Attempting to tension the chain when the bar nuts are tight can cause damage.

Checking the tension:

Use the screwdriver end of the combination screwdriver/wrench tool to move the chain around the bar. If the chain does not rotate, it is too tight. If too loose, the chain will sag be- low the bar.

Adjusting the tension:

Chain tension is very important. Chain stretches during use. This is especially true during the first few times you use your saw. Always check chain tension each time you use and refuel your saw.

You can adjust chain tension by loosening the bar clamp nuts and turning the adjust- ing screw 1/4 of a turn while lifting up on bar.

SIf chain is too tight, turn adjusting screw 1/4 turn counterclockwise.

If chain is too loose, turn adjustingS

screw 1/4 turn clockwise.

S Lift up the tip of the bar and tighten the bar clamp nuts with the combination screw- driver/wrench.

S Recheck chain tension.

FUELING ENGINE

This engine is certified to operate on unleaded gasoline. Before operation, gasoline must be mixed with a good quality

2-cycle air-cooled engine oil. We recommend Poulan/Weed Eater brand oil. If you do not use this oil, use a good quality 2-cycle air-cooled oil designed to be mixed at a ratio of 40:1 (A 40:1 ratio is obtained by mixing 3.2 onces of oil with 1 gallon of unleaded gasoline). When mixing fuel follow the instructions printed on the container. 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 lu- brication.

Always stop the engine before removingS

the oil cap.
