and felling cut are badly placed.

When the felling cut and directional cut are complete

the tree should start to fall under its own weight or

with the aid of a FELLING WEDGE or BREAKING BAR.

We recommend that you use a bar that is longer than

the diameter of the tree, so that you can make the

FELLING CUT and DIRECTIONAL CUT with single cut-

ting stokes. (See ”Technical data” to find out which

lengths of bar are recommended for your saw).

UNLESS YOU HAVE SPECIAL TRAINING WE ADVISE

YOU NOT TO FELL TREES WITH A DIAMETER LARGER

THAN THE BAR LENGTH OF YOUR SAW!

MOST KICKBACK ACCIDENTS HAPPEN DURING LIMB-

ING!PAY CLOSE ATTENTION TO THE POSITION OF THE

KICKBACK ZONE OF THE BAR WHEN YOU ARE LIMB-

ING BRANCHES THAT ARE IN TENSION!

Make sure there are no obstacles in your way. Work

on the left side of the trunk. Work close to the saw for

maximum control.

WARNING! Do not start the saw without the bar, chain

and clutch cover (chain brake) assembled. If you do,

the clutch might come loose and cause severe

injuries.

Operation

• The carburettor governs the engine speed via the throt-

tle. Air/fuel are mixed in the carburettor. The air/fuel

mixture is adjustable. To take advantage of the saw’s

maximum output the setting must be correct.

• Adjusting the carburettor means the engine is

adapted to local operating conditions, e.g. climate,

altitude, petrol and the type of 2-stroke oil used.

• The carburettor has three adjustment possibilities:

L = Low speed jet.

H = High speed jet.

T = Adjustment screw for idling.

• The fuel quantity required in relation to the air flow,

provided by opening the throttle, is adjusted by the

L and H-jets. If they are screwed clockwise the

air/fuel ratio becomes leaner (less fuel) and if they

are turned anti-clockwise the ratio becomes richer

(more fuel). A leaner mixture gives a higher engine

speed and a richer mixture give a lower engine

speed.

• The T screw regulates the idling speed. If the

screw T is turned clockwise this gives a higher

idling speed; anti-clockwise a lower idling speed.

Below you will find some general maintenance

instructions. If you have more questions, contact your

servicing dealer.

MAINTENANCE

1. Check the throttle trigger for smooth operation. If

any binding occurs, or if engine fails to return to

idle, the saw should be taken to your dealer,

before it is used again. Also, be sure that the trig-

ger cannot be pulled until the throttle trigger lock-

out is depressed.

2. Clean the chain brake and check its function

according to the instructions. Make sure that the

chain catcher is undamaged. Otherwise replace it

immediately.

3. Clean the air filter daily or more often if the air is

exceptionally dusty in the working area.

Disassemble the air filter by removing the cylinder

cover and unscrew the filter. When reassembling,

make sure that the filter is tight against the filter

holder. Clean the filter by brushing or shaking it.

A more thorough cleaning of the filter is obtained

by washing it in water and soap.

An air filter, which is used for some time, cannot

be cleaned completely. Therefore it must be

replaced by a new one, with regular intervals.

IMPORTANT! A damaged air filter must always

be replaced.

4. The bar should be turned daily for more even

wear. Check the lubrication hole in the bar, to be

sure it is not clogged. Clean the bar groove, if the

bar has a sprocket tip, this should be lubricated.

5. Check the function of the oiler to be sure the bar

and chain receive proper lubrication.

6. Sharpen the chain and check its tension and con-

dition. Check the drive sprocket for wear. Replace

if necessary.

7. Check the starter and starter cord for wear or

damage. Clean the air intake slots on the starter

housing.

8. Check for any loose nuts and screws and retight-

en if necessary.

9. Test the stop switch to be sure it shuts off the

engine.

10.Clean the spark plug and check the gap. The cor-

rect gap is 0.5 mm (.020 inch).
