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 kick-

back. The chain brake activates manually if the

front hand guard is pushed forward. The chain

brake is disengaged by pulling the front hand

guard back toward the front handle as far as

possible.

CHAIN TENSION

It is normal for a new chain to stretch during the

first 15 minutes of operation. You should check

your chain tension each time before you start

the chain saw. See CHAIN TENSION under

the ASSEMBLY section.

WARNING:

If the saw is operated

with a loose chain, the chain could jump off

the guide bar and result in serious injury to

the operator and/or damage the chain mak-

ing it unusable.

BEFORE STARTING ENGINE

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.

WARNING:

Be sure to read the fuel

handling information in the safety rules sec-

tion of this manual before you begin. If you do

not understand the fuel handling information

do not attempt to fuel your unit. Seek help

from someone that does understand the in-

formation or call the customer assistance

help line at 1-800-554-6723.

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 un-

leaded 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.

A 40:1 ratio is obtained by mixing 3.2 fluid

ounces (95 ml) of oil with 1 gallon (4 liters) of

unleaded gasoline. Included with this saw is

a 3.2 ounce (95 ml) container of Poulan/

Weed Eater brand synthetic oil. Pour the en-

tire contents of this container into 1 gallon (4

liters) of gasoline to achieve the proper fuel

mixture. DO NOT USE automotive or marine

oil. These oils will cause engine damage.

When mixing fuel follow the instructions

printed on the container. Always read and

follow the safety rules listed under HANDLE

FUEL WITH CAUTION.

CAUTION:

Never use straight gasoline in

your unit. This will cause permanent engine

damage and void the limited warranty.

FUEL REQUIREMENTS

This engine requires the use of minimum 87

octane [R+M]/2 clean gasoline.

IMPORTANT

Use of alcohol blended fuels (called gasohol or

using ethanol or methanol) can cause major

engine performance and durability problems.

WARNING:

Alternative fuels (not

gasoline) such as E--15 (15% alcohol), E--20

(20% alcohol), E--85 (85% alcohol) are NOT

classified as gasoline and are NOT approved

for use in 2--stroke gasoline engines. Use of al-

ternative fuels will cause problems such as: im-

proper clutch engagements, overheating, va-

por lock, power loss, lubrication deficiency,

deterioration of fuel lines, gaskets and internal

carburetor components, etc. Alternative fuels

cause high moisture absorption into the fuel/oil

mixture leading to oil and fuel separation.

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 fric-

tion. 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.

S

Never use waste oil for bar and chain lubri-

cation.

S

Always stop the engine before removing

the oil cap.

CHAIN BRAKE

Ensure chain brake is disengaged by pulling

the front hand guard back toward the front han-

dle as far as possible. The chain brake must be

disengaged before cutting with the saw.

WARNING:

The chain must not

move when the engine runs at idle speed. If

the chain moves at idle speed refer to CAR-

BURETOR ADJUSTMENT within this

manual. Avoid contact with the muffler. A hot

muffler can cause serious burns.

To stop the engine

move the ON/STOP

switch to the STOP position.

To start the engine

hold the saw firmly on the

ground as illustrated. Make sure the chain is

free to turn without contacting any object.
