Gasoline and Oil Mix 40:1 Oil Only
Recommended fuels
Some conventional gasolines are being blended
with oxygenates such as alcohol or an ether com-
pound to meet clean air standards. Your engine is
designed to operate satisfactorily on any gasoline
intended for automotive use including oxygenated
gasolines. It is recommended to use unleaded
petrol as fuel.
Lubrication of chain and chain bar
Whenever you refi ll the fuel tank with petrol you
must also top up the level of chain oil in the chain
oil tank. It is recommended to use standard chain
oil.
Engine pre-start checks
Danger: Never start or operate the saw unless
the bar and chain are properly installed.
1. Fill the fuel tank (A) with correct fuel mixture
(Fig. 8).
2. Fill the oil tank (B) with chain oil (Fig. 8).
3. Be certain the chain brake is disengaged (C)
before starting unit (Fig. 8).
Once you have fi lled the chain and oil tank, tigh-
ten the tank cover securely by hand. Do not use
any tools to do so.
6. Operation
6.1 Starting the engine
1. Set the On/Off switch (A) to “On (I)” to start
the machine (Fig. 9A).
2. Pull out the throttle lever (B) (Fig. 9B) until it
locks.
3. Push the primer bulb (C) 10 times (Fig. 9C).
4. Place saw on a fi rm, fl at surface. Hold saw
fi rmly as shown. Pull starter rapidly 2 times.
Beware of moving chain! (Fig.9D)
5. Push in the throttle lever (B) as far as it will go
(Fig. 9B).
6. Hold saw fi rmly and pull starter rapidly 4
times. Engine should start (Fig. 9D).
7. Let the engine run for 10 seconds to warm up.
Press the throttle lever (D) briefl y, the engine
will go to “idling” speed (Fig. 9E).
If engine failed to start, repeat these instructions.
Note: Always pull the starter cable slowly until
you feel the initial resistance before you then pull
it quickly to start the engine. Do not allow the star-
ter cable to whip back of its own accord.
6.2 Restarting a warm engine

te the chain brake and switch the ON/OFF switch

6.4 General cutting instructions
Danger: Felling trees is prohibited without the
necessary training!
Felling
•
Felling is the term for cutting down a tree.
Small trees up to 6-7 inches (15-18cm) in
diameter are usually cut in a single cut. Larger
trees require notch cuts. Notch cuts determi-
ne the direction the tree will fall.
•
A retreat path (A) should be planned and
cleared as necessary before cuts are started.
The retreat path should extend back and dia-
gonally to the rear of the expected line of fall,
as illustrated in Fig. 11.
•
If felling a tree on sloping ground, the chain
saw operator should keep on the uphill side of
the terrain, as the tree is likely to roll or slide
downhill after it is felled.
•
Direction of fall (B) is controlled by the not-
ching cut. Before any cuts are made, consider
the location of larger branches and natural
lean of the tree to determine the way the tree
will fall (Fig. 11).
•
Do not cut down a tree during high or chan-
ging winds or if there is a danger to property.
Consult a tree professional. Do not cut down
