OPERATING YOUR UNIT

BEFORE STARTING ENGINE

WARNING: Be sure to read the fuel

information in the safety rules before you be-

gin. If you do not understand the safety rules,

do not attempt to fuel your unit. Contact an

authorized service dealer.

BAR AND CHAIN LUB RICATION

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.Only use Bar and

Chain Oil for bar and chain lubrication.

Oil Cap

Fuel mix cap

FUELING ENGINE

WARNING: Remove fuel cap slowly

when refueling

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. 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

0,125 liter of oil with 5 liters of unleaded

gasoline. DO NOT USE automotive or boat

oil. These oils will cause engine damage.

When mixing fuel follow the instructions

printed on the container. Always read and

follow the safety rules relating to fuel before

fueling your unit.

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, empty the fuel

system 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. Never

use engine or carburetor cleaner products in

the fuel tank or permanent damage may

occur.

CHAIN BRA KE

Ensure chain brake is disengaged by pulling

the front hand guard back toward the front

handle 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 below. Make sure

the chain is free to turn without contacting

any object.

Hold saw firmly while pulling starter rope.

Use only 15”---18” of rope per pull.

IMPORTANT POINTS T O REMEMBER

When pulling the starter rope, do not use the

full extent of the rope as this can cause the

rope to break. Do not let starter rope snap

back. Hold the handle and let the rope rewind

slowly.

For cold weather starting, start the unit at

FULL CHOKE; allow the engine to warm up

before squeezing the throttle trigger.

NOTE: Do not attempt to cut material with

the choke/fast idle lever in the FULL CHOKE

position.
