CHAIN TENSION

(Including units with

chain already installed)

NOTE:

When adjusting chain tension,

make sure the chain brake nuts are finger

tight only. Attempting to tension the chain

when the chain brake nuts are tight can

cause damage.

Checking the tension:

Use the screwdriver end of the chain adjust-

ment tool (bar 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 below 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 the chain tension by

loosening the chain brake nuts and turning

the adjusting screw 1/4 of a turn while lifting

up on the bar.

S

If chain is too tight, turn adjusting screw 1/4

turn counterclockwise.

S

If chain is too loose, turn adjusting screw

1/4 turn clockwise.

WARNING:

If the saw is operated

with a loose chain, the chain could jump off

the guide bar and result in serious injury.

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

WARNING:

Remove fuel cap slow-

ly when refueling.

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 Husqvarna

R

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

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 listed under HANDLE

FUEL WITH CAUTION.

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.

Only use Bar and Chain Oil for bar and chain

lubrication.

STARTING

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.
